Computer networking is a process of sharing data and shared resources between two or more connected computers. The shared resources can include printer, Fax modem, Hard disk, CD – DVD Rom, Database and the data files. A computer network can be divided into a small or local area network, a networking between computers in a building of a office (LAN), medium sized network (MAN), a network between two offices in a city and Wide network (WAN) a network between the computers, one is locally and the other can be thousands of miles away in any other country of the world.

WAN connectivity is achieved by a network device known as “Router”. The internet is the world’s largest WAN network, where millions of computers from all over the globe and connected with each other.

Networking is the practice of linking two or more computers or devices with each other. The connectivity can be wired or wireless. A computer network can be categorized in different ways, depends on the geographical area as mentioned above.

There are two main types of the computer network client-server and peer to peer. In the client server computing, a computer plays a major role known as server, where the files, data in the form of web pages, docs or spread sheet files, video, database & resources are placed.

All the other computers in the client/server network are called clients and they get the data from the server. In the peer to peer network all the computers play the same role and no computer act as a centralized server. In the major businesses around the world client-server network model is in major use.

A network topology defines the structure, design or layout of a network. There are different topologies like bus, ring, star, mesh, hybrid etc. The star topology is most commonly used network topology. In the star topology, all the computers in the network are connected with a centralized device such as hub or switch. Thus forms a star like structure. If the hubs/switch fails to work for any reason then all the connectivity and communication between the computers of a network will be halted.

In the network, a common communication language is used by the computers and the network devices and this language is known as protocols. The most commonly used and popular protocols on the internet and in the home and other networks is called TCP/IP. TCP/IP is not a singleprotocol but it is a suite of several protocols.

A network can be a wired or wireless and TCP/IP protocol can work both in types of network.

A data flow in a computer network can be divided into seven logical layers called OSI layersmodel that was developed by Intel and Xerox Corporation and was standardized by ISO.

1. Application layer

2. Presentation layer

3. Session layer

4. Transport layer

5. Network layer

6. Data Link layer


a. Media access control sub-layer


b. Logical link control sub-layer

7. Physical layer.


A network can be divided into different scales and ranges and it depends on the requirement of the network and the geographical location. Computer Network can be divided into Local Area Network, Personal Area Network, Campus Area Network, Wireless Local Area Network,Metropolitan Area Network and Wide Area Network.

There are several network connection methods like HomePNA, Power line communication, Ethernet and Wifi connection method.A network can also be categorized into several different types based on the services it provides like Server farms, Storage area networks, Value control networks, Value-Added networks,SOHO network, Wireless network and Jungle networks.

Computer engineers have been finding ways to connect computers and their devices together in different ways. Computer networking has come hand in hand with other bodies of knowledge such as telecommunications, information technology, and computer engineering. So many things have been made possible through computer networking. It has helped people live easier lives in many ways through personal area network, local area network, metropolitan area network, and wide area network.

One great example of a wide area network is the champion of all networks, the Internet. It is the biggest network in the world, and billions of data (maybe even trillions) is being transferred everyday. So much information is exchanged and it has practically changed the way we live our lives.

Education online

The usual way to get your education is to enroll in a school, and go to your classes on a fixed schedule. Nowadays, we can actually get a college and master’s degree through the Internet. A lot of reputable universities now offer their courses online because they understand how hard it is for some students to juggle a job and their schooling. Depending on the program, you can have your own schedule, and usually you’d just have to submit work on or before a particular deadline. At times, you’d have real time chatting with you professor and “classmates”, sometimes even with a webcam. What’s great about this is that you no longer have to go through the hassle of commuting. The good news is that companies have been accepting a lot of applicants with this sort of education but there are still some that are overly traditional.

Video games galore

What started out as simple 2 dimension games is now a multi-billion dollar industry, and has spawned a new way of social interaction. Because of the Internet, gamers are now able to interact with people from across the globe, and play the same game at the same time. This is great because video games were once viewed as an anti-social activity. This is no longer true and now gamers not only get to play the game together, but are able to chat and make new friends as well. Internet gaming has also created a new gaming genre called “massively multiplayer online role-playing games” or MMORPGs. This is a supercharged type of RPG where thousands of players get to play together in a particular game at the same time.

Social Networking

A lot of websites nowadays allow people to interact and socialize with each other with their different tools and services. Some of them are focused on dating, where users can create their own profile and indicate their particular tastes. Other websites are dedicated to people uploading pictures and sharing them with other users as well. This has been a great way of connecting with long lost friends, and making new ones as well.

It’s great that computer networking has helped in bringing us the Internet. With it, life has become more convenient, and we can learn so many new things everyday just by connecting to it. With the Internet, there are certainly more new things to come.

Computer network training is one of the latest gateways to jump into the competitive IT world. Network is a media for computers to communicate with each other by sending files, instant messages and other information. This is accomplished through LAN (Local Area Network) and WAN (Wide Area Network). Nowadays, many companies use networks of computers to run their operations smoothly. So, computer networking is a good job option. Basically, there are two main networks, namely Microsoft and Novell.

Specialized degree and certificate network training programs are available through several institutions, schools and online coaching. Many schools conduct training courses as part of regular programs and vocation courses. Some of these schools have labs outside the classroom that students can attend during designated hours. Online training courses allow students to take their courses anytime, anywhere. In addition, you can purchase training courses individually or bundled, available on CD-ROM. Each regular training program extends from six months to one year.

Each networking training course comprises fundamental programs about the working plans of network, wiring and the types of software installed in computers. Normally, these basic courses run just for a few weeks. Students learn about workstations, servers, their functions, and different types of networking such as client server and peer to peer.

After the fundamental program, the training moves gradually toward the next higher part. In this phase, students can learn about individual systems and their differences. Many schools divide this phase into two operating systems, for Novell and Microsoft. Students can take either one or both. Each operating system course normally extends up to 3 months. But some schools concentrate on one system. Practical procedures such as installing workstation software, installing server software, wiring and finally, making a simple computer network are involved.

The students are prepared for the certification exams. The examination has a number of practice tests. Most centers allow their students to continue the training until they have passed the exams.

Computer networking is very important when it comes to in-house office jobs where the mutual connection of computers constitutes an important part of the whole work. Therefore, networking is an important element in today’s corporate world.

There are many professional technicians who have the to securely install whatever type of network you require. All networking vendors use the highest quality hardware and software to help insure that your network is trouble free so that you don’t have to worry about it. They also troubleshoot and maintain existing networks in homes and offices.

Most technicians are friendly, professional and qualified and will do everything in their power to make servicing your computer or network a positive experience. This means speaking in non-technical, easy-to-understand terms and explaining exactly what’s wrong, what your options are and what the estimated costs are. Computer network vendors and repairers provide support for all network platforms.

Of course, security should be your main concern. It should always be your number one priority when it comes to choosing a company to do your computer network repair. They should be fluent in all security program-related language, and should be able to communicate it in lay terms when needed. That way, you can work with them to decide what is the most efficient and least expensive route to take. However, do not skimp on this investment, for such skimping could hypothetically cost you your entire business in the long run.

Shop arouond for the most thorough and holistic service, and find the best situation for your company and your employees.

Computer networking or data communication is a most important part of the information technology. Today every business in the world needs a computer network for smooth operations, flexibly, instant communication and data access. Just imagine if there is no network communication in the university campuses, hospitals, multinational organizations and educational institutes then how difficult are to communicate with each other. In this article you will learn the basic overview of a computer network. The targeted audience of this article is the people who want to know about the network communication system, network standards and types.

A computer network is comprised of connectivity devices and components. To share data and resources between two or more computers is known as networking. There are different types of a computer network such as LAN, MAN, WAN and wireless network. The key devices involved that make the infrastructure of a computer network are Hub, Switch, Router, Modem, Access point, LAN card and network cables.

LAN stands for local area network and a network in a room, in a building or a network over small distance is known as a LAN. MAN stands for Metropolitan area network and it covers the networking between two offices within the city. WAN stands for wide area network and it cover the networking between two or more computers between two cities, two countries or two continents.

There are different topologies of a computer network. A topology defines the physical layout or a design of a network. These topologies are star topology, bus topology, mesh topology, star bus topology etc. In a star topology each computer in a network is directly connected with a centralized device known as hub or switch. If any computer gets problematic in star topology then it does not affect the other computers in a network.

There are different standards and devices in computer network. The most commonly used standard for a local area network is Ethernet. Key devices in a computer network are hub, switch, router, modem and access point etc. A router is used to connect two logically and physical different networks. All the communication on the internet is based on the router. Hub/Switch is used to connect the computers in local area network.

Hopefully, in this article you may have learnt that what a computer network is, how important it is in our lives, what are different network devices, standards, topologies and communication types.
