How does the internet work?
The internet works by connecting millions of computers, smartphones, servers, routers, data centers, wireless networks, and other devices through a global network of interconnected networks. These devices communicate by following standardized rules called protocols. When you open a website, your device does not simply connect to one giant computer called the internet. Instead, it communicates through several layers of hardware and software that identify the destination, divide information into packets, move those packets through networks, and reconstruct the information when it reaches the destination.
For example, when you enter a website address into a browser, several things happen within seconds. Your device connects to a local network, a domain name is translated into an IP address, routers determine where the traffic should go, packets travel through multiple networks, a web server receives the request, and the server sends data back to your device. The browser then interprets that data and displays the webpage.
This process may appear simple to users, but it involves many technologies working together. Internet service providers, fiber-optic cables, cellular networks, Wi-Fi equipment, routers, switches, DNS servers, web servers, cloud platforms, and communication protocols all contribute to the experience.
What is the internet?
The internet is a worldwide collection of interconnected networks. The word internet can be understood as an interconnected network system rather than a single physical object. Universities, companies, governments, data centers, internet service providers, homes, mobile networks, and other organizations operate networks that can communicate with one another.
There is no single machine that contains the entire internet. Instead, the internet is distributed across an enormous infrastructure. Different organizations own and operate different parts of this infrastructure, while common technical standards allow their networks to communicate.
Your home Wi-Fi network is one example of a small network. Your router connects devices such as laptops and smartphones to an internet service provider. The provider connects your local network to larger networks. Those networks connect to other networks, eventually providing paths to servers and services located anywhere in the world.
What happens when you open a website?
Suppose you type a website address into a browser. The browser first needs to understand which server should receive the request. A domain name such as example.com is designed for people to remember, while computers communicate using IP addresses.
The browser therefore needs to discover the IP address associated with the domain. This process involves the Domain Name System, commonly called DNS. After obtaining the required address, the browser can establish communication with the destination server.
The request then travels through your local network, your internet service provider, and potentially several intermediate routers. Eventually, it reaches the appropriate server or infrastructure responsible for the website.
The server processes the request and sends a response. The response may contain HTML, CSS, JavaScript, images, fonts, videos, JSON data, and other resources. The browser downloads these resources and uses them to construct the webpage that you see.
What is a network?
A network is a collection of connected devices that can communicate and exchange information. A network may be extremely small, such as two computers connected directly, or extremely large, such as a telecommunications provider serving millions of customers.
Networks use physical and wireless connections. Ethernet cables, fiber-optic cables, copper cables, Wi-Fi radio signals, cellular connections, microwave links, and satellite systems can all carry network traffic.
Networks are connected to other networks through specialized infrastructure. This is one of the fundamental ideas behind the internet. Instead of requiring every computer to have a direct connection to every other computer, networks connect through intermediate systems and exchange traffic according to agreed protocols.
What is an internet service provider?
An internet service provider, or ISP, is an organization that provides customers with access to the internet. Depending on the region and service, an ISP may deliver connectivity through fiber, cable, DSL, fixed wireless, mobile networks, or other technologies.
When your phone or computer connects to the internet, your traffic normally passes through an access network operated by a provider. The provider then connects that traffic to other networks that can reach the requested destination.
An ISP does not necessarily host every website that its customers visit. It primarily provides the connectivity required to communicate with networks and services operated by other organizations.
What is an IP address?
An IP address is a numerical address used to identify a device or network interface within an Internet Protocol network. IP addresses allow network traffic to be directed toward the intended destination.
IPv4 addresses use a format such as 192.0.2.1, while IPv6 uses a much larger address space and a hexadecimal format such as 2001:db8::1. The growth of connected devices has made IPv6 increasingly important because IPv4 provides a limited number of unique addresses.
Your device may use a private IP address inside your home or organization while the router uses a public address for communication with external networks. Network address translation can allow multiple private devices to share a public IPv4 address.
What is DNS?
The Domain Name System translates human-readable domain names into IP addresses and provides other information used by internet services. It works somewhat like a distributed directory for internet names.
People generally prefer names such as dfluxspace.com because they are easier to remember than numerical IP addresses. Computers and network systems need addresses to locate destinations. DNS connects these two needs.
When a browser needs to access a domain, it can use a DNS resolver to find the relevant record. The resolver may obtain the information from cached data or query other DNS servers. Once the appropriate address is known, the browser can continue the connection process.
What is a DNS resolver?
A DNS resolver is a service that handles DNS queries on behalf of a client. Your device may be configured to use a resolver supplied by an internet service provider, organization, operating system, router, or another DNS service.
If the resolver already has a valid cached answer, it may return the address without performing the entire lookup again. DNS caching reduces repeated queries and can improve response times.
DNS uses different types of records for different purposes. An A record commonly maps a domain name to an IPv4 address, while an AAAA record maps a domain to an IPv6 address. Other records can support email delivery, aliases, verification, and additional services.
What are routers?
Routers are networking devices that forward packets between networks. They examine information in network packets and use routing information to determine where traffic should be sent next.
Your home router may connect your devices to your ISP. Larger routers operate inside provider networks and internet exchange environments. These systems can process enormous quantities of traffic.
A router does not normally need to know the entire journey of every packet in the same way that a person might plan a complete road trip. Instead, routing systems determine an appropriate next hop based on available routing information.
How does internet routing work?
Internet routing is the process of determining paths for traffic between networks. The internet is made up of many independently operated networks called autonomous systems. These networks exchange routing information using protocols such as Border Gateway Protocol, or BGP.
BGP allows participating networks to advertise which IP address ranges they can reach. Other networks use this information to build routing decisions. Policies, network topology, performance considerations, and operational requirements can influence the paths selected.
As a result, the route between two computers can involve multiple networks and can change over time. Internet routing is dynamic rather than a single permanent route established for every possible pair of devices.
What are data packets?
Information sent across the internet is generally divided into smaller units called packets. Instead of sending a large piece of data as one uninterrupted block, network protocols break information into manageable pieces that can travel through the network.
Packets contain control information that helps networking equipment determine how to process and deliver them. The exact structure depends on the protocols being used.
Different packets belonging to the same communication can sometimes travel through different paths. At the destination, appropriate protocols can help put the information back together and detect missing or damaged data.
Why does the internet use packets?
Packet-based communication makes large networks more flexible and efficient. Multiple users and applications can share network infrastructure instead of requiring a dedicated physical connection for every communication session.
If one route becomes unavailable or congested, routing systems may be able to use another route. Packets also allow network equipment to process traffic from many applications at the same time.
Packet switching is therefore one of the fundamental concepts behind modern computer networking. It allows diverse applications, devices, and networks to share common infrastructure.
What is TCP?
Transmission Control Protocol, or TCP, is a transport-layer protocol designed to provide reliable, ordered delivery of data between applications. It can detect lost data and request retransmission when necessary.
TCP establishes a connection between communicating endpoints and uses mechanisms such as sequence numbers, acknowledgments, retransmissions, and flow control. These features help applications receive data in the expected order.
Traditional web traffic commonly used TCP, although modern web protocols can also use other transport technologies. The choice depends on the protocol and application requirements.
What is IP?
Internet Protocol, or IP, is responsible for addressing and forwarding packets between networks. IP provides the fundamental addressing and packet-delivery framework used by the internet.
IP itself does not guarantee that every packet will arrive, arrive only once, or arrive in a particular order. Higher-level protocols can provide reliability or other communication features when required.
TCP and IP are often discussed together because they form important parts of the traditional internet protocol suite. Modern networking also includes UDP, QUIC, HTTP, TLS, DNS, and many other protocols.
What is HTTP?
Hypertext Transfer Protocol, or HTTP, is a protocol used for transferring resources between clients and servers. Web browsers use HTTP to request webpages and related resources from web servers.
An HTTP request can specify a method such as GET, POST, PUT, PATCH, or DELETE depending on the operation. The server returns an HTTP response containing a status code and potentially data.
For example, a successful request for a webpage may return status code 200. A requested resource may return 404 when it cannot be found, while server-side problems can produce 5xx status codes.
What is HTTPS?
HTTPS is HTTP protected by Transport Layer Security, commonly called TLS. It provides encryption and authentication features for communication between a client and server.
Encryption helps prevent third parties on the network from simply reading the transmitted content. TLS also helps a browser verify that it is communicating with a server associated with the requested domain through a valid certificate and trusted certificate chain.
HTTPS is particularly important for login forms, payments, personal information, business systems, and ordinary web browsing. Modern websites commonly use HTTPS as a standard security measure.
What happens when you search on Google?
When you submit a search query, your browser sends a request to the search service. DNS helps locate the appropriate service infrastructure, while network routing delivers the request.
The search service processes the query against its search index and ranking systems. The results are then returned to the browser, where the page is rendered for the user.
This process involves many backend systems rather than a single computer. Search engines operate large distributed infrastructures containing servers, storage systems, databases, networking equipment, software services, and data centers.
What is a web server?
A web server is a system that receives web requests and returns resources or generated responses. The term can refer to the hardware, operating system, software, or overall server environment depending on context.
Common web server software includes systems such as Nginx and Apache HTTP Server. Applications can also run behind reverse proxies, application servers, serverless platforms, content delivery networks, and cloud infrastructure.
A website may be served by one machine in a simple deployment or by many distributed systems in a large production environment.
What is a data center?
A data center is a facility designed to operate computing and networking infrastructure. It can contain servers, storage systems, network switches, routers, power systems, cooling equipment, physical security systems, and monitoring infrastructure.
Large internet companies operate multiple data centers in different geographic regions. Distributing infrastructure can improve availability, capacity, and latency for users in different locations.
Cloud computing providers also operate large data center environments and provide computing, storage, database, networking, and other services to organizations.
How does Wi-Fi connect to the internet?
Wi-Fi provides wireless communication between compatible devices and a wireless access point or router. Wi-Fi itself is not the entire internet. It is one method of connecting a local device to a local network.
When your laptop connects to home Wi-Fi, the wireless connection carries data between the laptop and the router. The router then forwards appropriate traffic to the ISP and onward through other networks.
This distinction is useful because internet access can work through many technologies. A device may use Ethernet, Wi-Fi, cellular data, or another access method while ultimately communicating with internet-based services.
How does mobile internet work?
Mobile internet uses cellular radio networks to connect phones and other devices to carrier infrastructure. The device communicates with a nearby cellular base station, which connects the traffic to the mobile operator's core network.
From there, traffic can reach other networks and internet services. Modern cellular technologies provide increasingly high data rates and lower latency, although actual performance depends on coverage, network conditions, device capabilities, congestion, spectrum, and other factors.
What are fiber-optic cables?
Fiber-optic cables transmit information using pulses of light through optical fibers. They can carry large quantities of data over long distances and form a major part of global internet infrastructure.
Undersea fiber-optic cables connect continents and carry substantial amounts of international internet traffic. Terrestrial fiber networks connect cities, data centers, internet exchanges, businesses, and access networks.
Although users often experience the internet as wireless, much of the long-distance infrastructure underneath internet services depends on physical fiber connections.
What are undersea internet cables?
Undersea communication cables are fiber-optic cables laid across the seabed to connect different geographic regions. They form a critical component of international telecommunications infrastructure.
These cables carry internet traffic, cloud service traffic, video calls, financial communications, and many other forms of digital information. Multiple cable systems can provide alternative connectivity between regions.
The existence of undersea cables illustrates that the internet is not entirely wireless. A substantial portion of global connectivity relies on physical infrastructure extending across land and oceans.
What is a CDN?
A Content Delivery Network, or CDN, is a distributed collection of servers that can deliver content from locations closer to users. CDNs are commonly used for images, JavaScript, CSS, videos, downloads, and other web resources.
When a website uses a CDN, a user may receive cached content from a nearby edge location rather than retrieving every resource directly from the origin server.
CDNs can reduce latency, improve scalability, and help websites handle large numbers of requests. They are widely used by news sites, software platforms, e-commerce services, streaming services, and other high-traffic websites.
What is latency?
Latency is the time required for data to travel between endpoints or for a network operation to receive a response. Lower latency generally means interactions feel more immediate.
Latency depends on physical distance, routing, network equipment, congestion, processing time, wireless conditions, and application architecture. A server located geographically closer to a user can often provide lower network latency, although physical distance is only one factor.
Latency is particularly important for video calls, online gaming, remote desktop applications, financial systems, interactive websites, and other real-time applications.
What is bandwidth?
Bandwidth describes the capacity of a network connection to transfer data over a period of time. It is commonly expressed in bits per second, such as Mbps or Gbps.
Bandwidth and latency are different concepts. A connection can have high bandwidth but still experience noticeable latency. Conversely, a connection can have low latency but limited bandwidth.
Streaming high-resolution video, downloading large files, and serving many simultaneous users can require substantial bandwidth. Network capacity can also be shared among many users.
How does video streaming work?
When you stream a video, the application requests media data from a server or CDN. The video is usually divided into segments or delivered through a streaming protocol designed for continuous playback.
The player maintains a buffer containing some upcoming content. If network conditions change, adaptive streaming technologies can select different quality levels to balance video quality and uninterrupted playback.
The content may be delivered from infrastructure geographically distributed around the world. This is why the same streaming service can provide content to users in many countries without requiring every user to connect to one physical server.
How does email work on the internet?
Email uses several protocols and services. When a person sends an email, the message is submitted to a mail server. Mail systems use DNS records, particularly MX records, to determine which servers accept email for a domain.
SMTP is commonly used for transferring email between mail servers and for submitting messages. Protocols such as IMAP allow mail applications to access messages stored on servers.
Spam filtering, authentication mechanisms, encryption, storage systems, and other services may also participate in modern email delivery.
How does online banking communicate securely?
Online banking applications typically use encrypted connections such as HTTPS to protect communication between the user's device and the service infrastructure. Authentication systems verify users before granting access to account functions.
Modern financial applications can include multiple layers of security, such as multi-factor authentication, session management, fraud monitoring, access controls, encryption, and transaction verification.
The internet provides the communication infrastructure, while the banking application and its supporting systems implement the specific security and financial controls required by the service.
How does cloud computing use the internet?
Cloud computing allows organizations and individuals to access computing resources through networked infrastructure. Cloud providers operate large collections of servers, storage systems, databases, networking equipment, and software services.
A developer can deploy an application to a cloud platform and allow users around the world to access it through the internet. The application may use load balancers, databases, object storage, content delivery networks, containers, virtual machines, or serverless functions.
Cloud computing therefore extends the internet model by making computing infrastructure available as an on-demand service.
What happens when an app connects to an API?
An application programming interface, or API, allows software systems to communicate using defined interfaces. A mobile application might call an API to retrieve user data, submit an order, process a payment, or request search results.
The application sends a network request to an API endpoint. DNS can resolve the endpoint's domain, network routing delivers the request, and the API server processes it. The server may then access databases or other internal services before returning a response.
Many modern applications therefore depend on several networked services rather than one standalone program.
How does the internet know where to send information?
The internet uses addressing and routing mechanisms to move packets toward their destinations. IP addresses identify destinations, while routers use routing tables to determine suitable next hops.
At each stage, a router examines relevant packet information and forwards it toward another network. The process continues until the packet reaches the destination network and eventually the destination device or service.
This layered approach allows the internet to scale without requiring every router to maintain a direct connection to every other device on Earth.
Can internet packets take different routes?
Yes. Internet traffic can take different routes depending on network topology, routing policies, failures, congestion, maintenance, and other conditions. The path used at one moment may differ from the path used later.
Different packets belonging to the same communication can also potentially encounter different network paths. Higher-level protocols are designed to deal with these possibilities.
This flexibility contributes to the resilience of the internet. If a particular link becomes unavailable, routing systems can sometimes redirect traffic through alternative paths.
Is the internet the same as the World Wide Web?
No. The internet and the World Wide Web are related but different concepts. The internet is the broader network infrastructure and protocol ecosystem that connects devices and networks.
The World Wide Web is a service that operates over the internet and uses technologies such as HTTP, URLs, HTML, CSS, JavaScript, browsers, and web servers.
Email, online gaming, messaging systems, file transfer, voice communication, and many other services can use the internet without being the World Wide Web itself.
How do browsers display webpages?
A browser receives resources from web servers and processes them. HTML provides the document structure, CSS controls presentation, and JavaScript can add interactive behavior and application logic.
The browser parses these resources, constructs internal representations of the page, calculates layout, paints visual elements, and displays the result. Additional resources such as images, fonts, videos, and API responses may be downloaded during this process.
Modern browsers also include networking, security, storage, caching, rendering, JavaScript execution, and developer tools.
What is browser caching?
Browser caching allows a device to store copies of certain web resources for later use. If a resource has not changed and its caching policy allows reuse, the browser may avoid downloading it again.
Caching can reduce bandwidth consumption and improve page loading performance. Websites can define cache-control behavior so browsers and intermediary systems know how long resources can be reused.
CDNs and proxy systems can also cache content, creating multiple layers of caching between a user and an origin server.
How does internet security work?
Internet security is not provided by one single technology. It involves encryption, authentication, authorization, secure protocols, software updates, firewalls, intrusion detection, access controls, monitoring, backups, and secure application design.
TLS protects many client-server connections. Password systems should use secure storage techniques rather than storing plaintext passwords. Multi-factor authentication can add another verification factor beyond a password.
Applications must also defend against vulnerabilities such as injection attacks, cross-site scripting, broken access control, insecure dependencies, and improper handling of sensitive information.
What is encryption?
Encryption transforms readable information into a form that cannot be easily understood without the appropriate key. In internet communications, encryption helps protect information from unauthorized observation while it travels between systems.
HTTPS uses TLS to establish protected communication between clients and servers. Encryption does not automatically make an entire application secure, however. Authentication, authorization, software security, server configuration, and data handling remain important.
Why can the internet become slow?
Internet performance can be affected by many factors. A user's Wi-Fi signal may be weak, the access network may be congested, an ISP link may be busy, a remote server may be overloaded, or routing may involve a distant path.
Large downloads can consume available bandwidth. Wireless interference can reduce performance. High latency can make interactive applications feel slow even when download bandwidth is substantial.
Websites can also contribute to perceived slowness through large images, excessive JavaScript, inefficient backend processing, slow databases, or poorly optimized resources.
What happens if an internet connection is interrupted?
If a network link fails, active connections can be interrupted. Depending on the architecture, routing systems may discover another available path and redirect future traffic.
Applications can also implement retry mechanisms, connection recovery, buffering, and offline storage. The result depends on the service and the type of failure.
The distributed nature of the internet provides resilience, but it does not guarantee uninterrupted access. Physical cable failures, equipment problems, power outages, configuration mistakes, natural events, and large-scale infrastructure incidents can still affect connectivity.
How do multiple users share the internet?
Internet infrastructure is shared among many users. A home router can allow several devices to use the same connection. An ISP aggregates traffic from many customers and carries it through larger network links.
At larger scales, providers use high-capacity routers, switches, optical systems, and interconnection facilities to handle traffic from many networks simultaneously.
Because traffic is bursty, shared infrastructure can be used efficiently when capacity is properly engineered. Congestion occurs when demand exceeds available capacity on a link or system.
What are internet exchange points?
Internet Exchange Points, commonly called IXPs, are facilities where networks can interconnect and exchange traffic. Direct interconnection can allow networks to exchange traffic without sending it through additional intermediary networks in some circumstances.
IXPs can improve network efficiency and reduce unnecessary transit. They are important components of internet infrastructure in many regions.
The global internet therefore consists of many forms of interconnection, including private network links, transit relationships, peering arrangements, data centers, IXPs, and access networks.
How does a domain become connected to a website?
A domain becomes associated with a website through DNS configuration and server infrastructure. The domain owner can configure DNS records that point the domain toward an IP address or another appropriate service.
The web server or hosting platform then needs to recognize the domain and serve the appropriate website when requests arrive. HTTPS certificates are also configured so secure browser connections can be established.
Hosting providers can simplify these tasks by offering domain configuration, certificates, DNS management, deployment systems, databases, storage, and other services.
What is an IP packet header?
An IP packet contains a header with information needed for network processing. Depending on the IP version, the header includes fields such as source and destination addresses and information relevant to packet handling.
Network equipment uses these fields to determine how traffic should be processed and forwarded. Other protocols add their own headers to support transport, security, application, or other functions.
Layered headers are one reason network communication can support many different applications over common infrastructure.
What is a port number?
A port number identifies a communication endpoint associated with a transport-layer service on a host. IP addresses identify network interfaces or destinations, while ports help identify the application or service receiving traffic.
For example, web services commonly use TCP port 80 for HTTP and TCP port 443 for HTTPS, although software can be configured differently and modern protocols may use other transport arrangements.
Ports allow multiple network services to operate on the same IP address without all traffic being delivered to one application.
How do passwords travel over the internet?
When a user signs into a properly configured website, the login request should normally be protected by HTTPS. TLS encrypts the communication between the browser and server, helping prevent network observers from reading the transmitted password.
The server should then process the credential securely. Good authentication systems do not store passwords as ordinary readable text. Password hashing and appropriate authentication controls are used to reduce the impact of credential database exposure.
Users should also avoid entering credentials into suspicious websites and should enable multi-factor authentication where available.
How does internet infrastructure support artificial intelligence?
Modern artificial intelligence services often depend heavily on internet infrastructure. Users send prompts, images, audio, or other data to AI applications through network connections. The service processes that information on servers and returns a response.
Large AI systems may operate across clusters of specialized computing hardware in data centers. The application layer, databases, storage systems, networking infrastructure, authentication services, and content delivery systems can all work together.
This means an AI application can be considered another type of internet service built on top of the same broad networking principles.
How does the internet support social media?
Social media applications use internet-connected servers to store accounts, posts, images, videos, comments, messages, and other data. A mobile or web application communicates with backend APIs to retrieve and submit information.
Large social platforms typically distribute their infrastructure across multiple data centers and use caching, databases, CDNs, load balancing, queues, and other technologies to serve large numbers of users.
When a user uploads a photo, for example, the application may upload the file to storage, create optimized versions, update metadata, and distribute the image through a CDN.
How does the internet support online shopping?
An e-commerce website uses internet connectivity to allow customers to browse products, manage shopping carts, submit orders, and communicate with payment and fulfillment systems.
A typical transaction may involve several services. The browser communicates with the store, the store accesses product and inventory databases, payment information is sent to a payment processor, and order information may be sent to logistics or fulfillment systems.
Secure communication, authentication, authorization, fraud detection, and data protection are important because e-commerce systems handle valuable information.
How does the internet continue to evolve?
The internet continues to evolve as more devices, applications, and services become connected. Technologies such as IPv6, faster fiber networks, 5G and newer cellular systems, edge computing, cloud platforms, content delivery networks, and modern transport protocols are changing how applications are delivered.
Internet architecture also continues to respond to increasing demand for video, cloud computing, artificial intelligence, connected devices, remote collaboration, gaming, and real-time communication.
At the same time, network operators and software developers must address security, privacy, reliability, scalability, energy consumption, interoperability, and resilience.
What is the internet in simple terms?
In simple terms, the internet is a huge network of networks that allows computers and other devices to exchange information. Your device connects to a local network, that network connects to an internet service provider or another access network, and the traffic travels through interconnected networks toward the requested destination.
DNS helps translate names into addresses. IP provides addressing and packet forwarding. Routers move packets between networks. Transport protocols help applications communicate. HTTP and HTTPS support web applications. Servers process requests and return information. Browsers interpret the returned data and display it to users.
All of these technologies work together so that an action that appears simple, such as opening a webpage, can involve many systems operating across different physical locations.
Why understanding the internet matters
Understanding how the internet works is useful for students, developers, business owners, content creators, cybersecurity professionals, and ordinary users. It explains why websites sometimes load slowly, why DNS changes can take time to propagate, why HTTPS matters, why servers can become unavailable, and why a website can be hosted in one country while serving visitors around the world.
For developers, networking knowledge makes it easier to understand APIs, databases, authentication, cloud deployment, web hosting, caching, CDNs, DNS configuration, HTTP status codes, and application performance. For everyday users, basic knowledge helps explain what happens when a device connects to Wi-Fi, loads a website, sends a message, or streams a video.
The internet is not one machine and it is not one cable. It is a continuously operating ecosystem of physical infrastructure, network protocols, software systems, data centers, service providers, and interconnected networks. Its ability to move information globally comes from standardized communication methods and the cooperation of many independently operated systems.
Conclusion
The internet works by connecting networks and devices through standardized protocols that allow digital information to travel from one endpoint to another. When you visit a website, your device uses networking hardware and software to connect to a network, DNS helps locate the destination, routers forward packets, transport protocols manage communication, and web servers return the requested resources.
Behind this apparently simple process are fiber-optic cables, wireless networks, routers, switches, data centers, DNS infrastructure, cloud platforms, web servers, CDNs, security systems, and many other components. Together, these technologies create the global communication system that supports websites, applications, email, streaming, online banking, cloud computing, artificial intelligence, social media, and countless other services.
Once the basic concepts of IP addresses, DNS, packets, routing, HTTP, HTTPS, servers, and networks are understood, many everyday internet activities become much easier to explain. The internet is fundamentally a system for moving information between interconnected networks, using shared technical standards so that devices operated by different organizations can communicate.
