What is a Computer Network and How Does it Work

There are many different types of computer networks, each describing the intended purpose and geographic area they serve. Today, as the global economy continues its transition from analog to digital, companies are beginning to embrace a major paradigm shift. Fully digitizing their businesses is a top priority, and modern networks have become essential components in maintaining business continuity and a consistent user experience. These features make them essential components of today’s network architecture. But what is a computer network and how does it work?

Internet is a computer network

The Internet is a global network of computers that enable data exchange and transmission. It includes both public and private networks, academic, government, and business networks. It is connected by a wide array of networking technologies, including Internet Protocol (IP). These networks carry a vast range of information resources and services. For example, the Internet can send emails, download music, or watch television programs from one location to another. This type of networking is known as peer-to-peer (P2P).

The Internet connects millions of computers worldwide and enables world-wide communication. These networks share a common protocol known as TCP/IP, or Transfer Control Protocol. It requires a computer, modem, and an Internet connection. Colleges often provide direct Internet access to students. If you are not sure where to get a connection, ask your teacher or professor. You may be able to get free Internet access at an institution in your area.

The Internet was originally designed for scientific information sharing, but it has evolved to include online shopping and personal blogs. Redundancy exists in the Internet because of multiple pathways. This means that if one pathway is down, there is another, more reliable route available. Redundancy is crucial because the Internet is very large and has so many users and connections. However, if you don’t have a high-speed Internet connection, you might end up waiting a long time for your email to arrive.

Peer-to-peer networks

A peer-to-peer computer network is a distributed application architecture where tasks and workloads are shared among peers. Each peer has an equal stake in the application, and collectively they form a peer-to-peer network of nodes. Each peer can also be considered a single computer. This architecture enables users to share resources and process large amounts of data. Peer-to-peer computer networks are particularly useful for large-scale, distributed applications.

Peer-to-peer computer networks are used for several purposes. For example, in a spelling bee, a peer-to-peer computer network 100 can broadcast audio and video of each contestant’s attempt to spell the contest word. Each participating peer receives a broadcast of the contestant’s attempt and responds by broadcasting the appropriate spelling. A control computer 110 can then generate instructions to synchronize the broadcast data from each peer. This can be done by examining the time stamps of each broadcast.

The size of a peer-to-peer network depends on its architecture. For example, a network with twelve million users may have three million nodes, but each node can only connect to a handful of them. Because of this, the number of nodes that each user can search for a particular file is limited. A single user may be able to search for a particular file only on a small number of nodes, or they might not even know about it.


Ethernet is a family of wired computer networking technologies that are used in local, wide area, and metropolitan networks. Ethernet was first commercially introduced in the 1980s and standardized as IEEE 802.3 in 1983. Its usage has expanded from its humble beginnings in computer networks to the internet. To understand Ethernet and its uses, we need to know more about the Ethernet standard. We’ll discuss some common applications of Ethernet in this article, as well as how it differs from other computer networking technologies.

One of the benefits of Ethernet is its flexibility. Ethernet is ideal for small devices and bandwidth-intensive applications. It can easily handle many different types of data without any special configuration. Since it breaks information down into frames, it’s easy to route them through a network. Ethernet can handle the most complex networking needs, so it’s easy to see why it’s a popular choice for many companies. Listed below are some of the other benefits of Ethernet.

The Ethernet standard was created by Xerox engineers in 1973. Inspired by a project at the University of Hawaii, Ethernet was the first computer network. Its raw speed could only reach 2.94 Mb/sec, but it was enough to connect two computers. Ethernet’s rapid adoption and wide-spread use have made it the standard of choice for office networks. This technology has paved the way for the Internet.

Wireless networks

A wireless network uses wireless data connections between network nodes. Wireless networks can be used for a variety of purposes, from teleconferencing to file sharing. A wireless computer network may be created for use in a small business or at home. Here are some examples of how you can set up one. Let’s start by defining a wireless network. There are two basic types: fixed and mobile. Depending on your needs, either type may work.

Fixed wireless networks require more security than those that are wireless. Wireless computer networks are often less secure than wired ones, but recent articles have indicated that there are some that are less vulnerable. You can read more about wireless network security by searching for the phrase “wireless networks.”

A wireless network can span large areas. The advantages of wireless networking are numerous. First of all, it allows communication between devices in areas that are difficult to wire, such as an office building or a warehouse. Second, it provides free space in a home. Wireless networks can even be used for emergency services, which use them to send information to remote locations. And because wireless networks can reach so many different locations, wireless networking is a great alternative to traditional wired networks.


In a local area network, the computers are connected to each other via a local network interface. LANs are usually limited to a physical area, such as a home, office building, or school. Wide area networks, on the other hand, can cover a large geographical area and generally involve leased telecommunications circuits. In both cases, the network interface is a proprietary protocol, so you may not be able to share your network with others.

A local area network, or LAN, is a private network that connects computers and other hardware within a certain geographic area. Typically, LANs use wired connections to connect computers and peripheral devices. The computers and other devices connected to a LAN can share data. Users can also communicate through chat or email. LANs can be very useful for small businesses, as well as for connecting personal computers to printers.

For a basic LAN setup, you will need a router and at least one computer. The router will then be connected to each other through a wired or wireless connection. In larger networks, you will likely need a switch or multiple routers to exchange data. LANs are an excellent choice for small businesses because they can help reduce costs by sharing resources. Most importantly, LANs eliminate the need for additional desk space.


A WAN is a type of network that connects multiple LANs or computer networks. It enables users in one location to connect to computers in other locations. While many WANs are privately built for a single organization, others connect the LAN to the Internet. No matter how large the network is, the ability to connect users from different locations is important for business. Here are some common types of WANs.

A WAN is a type of computer network that can span an entire region, country, continent, or even the world. It can connect any number of computers to share regional resources. Typically, WANs are created by service providers and leased to their customers. In this case, each customer requires access to a WAN and can do so via several different links. But what exactly is a WAN? And how do you design one?

LANs operate in a closed area, typically sharing a single point of Internet connectivity. WANs, on the other hand, span large distances and are comprised of many connected LANs. An organization may use a WAN to connect multiple locations, which is why it has to have a central point of Internet connectivity. The difference between a LAN and a WAN is that a LAN uses a single router, while a WAN requires multiple switches and WANs use several different LANs connected to a central point.

Viruses and malware spread through a computer network

There are many ways to get a virus or malware onto your computer. Some are simple and are hidden within shared files, others spread through computer networks. These malicious programs will take over the computer and change its settings, including your home page URL and search preferences. Viruses can also change your computer’s behavior by redirecting you to malicious websites to steal your data and earn money for the attackers. Many viruses are “resident” or stay in the computer’s memory until they are activated by their victims. Other malware will stay dormant until a certain date or time is triggered.

Viruses spread through computer networks by attaching to files and activating when they are opened or clicked on. The infected files and programs spread through computer networks in the same way as viruses and other malware. Viruses can be transmitted through email attachments, USB drives, and file collaboration apps. Then, the infected files spread to other systems. They can also migrate to other systems via the internet and computer networks.
