Everything You Have To Know About Computer Networking
Computer networking, usually called datacom or data communication is the practice of linking two or more computer systems with each other to interchange information. Computer networking is considered a branch of computer science, IT, telecommunications and/or computer engineering because it greatly relies on the theory and practical application of these mentioned areas.
There are 3 kinds of computer networks namely the internet, intranet and then the extranet.
- The Internet - is a worldwide system of networks of computers that are connected. These networks make use of Internet Protocol Suite which is either TCP or IP, which serves millions of computer users all over the world.
- The Intranet - in contrast to the internet, the intranet is a private computer network. Although the intranet uses Internet Protocol technology, the data is secured within the company and not shared to the world.
- The Extranet - at the same time is actually an extension of a company's intranet. Its primary purpose is to enable users from outside the organization such as vendors, partners, and suppliers to access specific data and information.
Here are a few of the many ways of networking computers:
- Local Area Network - or generally known as LAN, is a small network of computer systems in a small area. One example of LAN is a network of computer systems in a building.
- Metropolitan Area Network - or MAN is similar to LAN. The significant difference is that MAN is used in a larger scale such as metropolitan areas or states.

- Wireless LANs and WANs - are like WAN and LAN and the only difference is the fact that they are wireless.
In computer networking, there are many ways to interconnect computer systems such as the use of coaxial cables, optical fibers, and also by means of power lines. But as technology improvements there are newer ways to do this such as wireless technologies which includes Bluetooth and Wi-Fi.
