Exactly What You Need To Know About Computer Networking
Computer networking, more commonly known as datacom or data communication is the practice of connecting several computer systems together to interchange data. Computer networking is recognized as a branch of computer science, information technology, telecommunications and/or computer engineering since it heavily depends on the concept and application of these mentioned fields.
There are 3 types of computer networks to be exact the internet, intranet and the extranet.
- The Internet - is a global system of networks of computers that are interconnected. These networks use Internet Protocol Suite which may be either TCP or IP, which in turn serves billions of computer users throughout the world.
- The Intranet - unlike the internet, the intranet is an exclusive computer network. Even though the intranet makes use of Internet Protocol technologies, the information is protected in the organization and not shared to the entire world.
- The Extranet - on the other hand is actually an expansion of a company's intranet. Its main purpose is to allow users from outside the company like manufacturers, associates, and suppliers to gain access to some information and data.
Below are a few of the various ways of networking computers:
- Local Area Network - or more commonly abbreviated as LAN, is a small network of computers in a limited area. One instance of LAN is a network of computers in a building.
- Metropolitan Area Network - or MAN is similar to LAN. The only difference is that MAN is employed in a bigger scale like cities or states.
- Wide Area Network - or WAN is a much bigger network when compared with MAN and is used to cover larger geographic regions.
- Wireless LANs and WANs - are just like WAN and LAN and the only real difference is that they are wireless.
In computer networking, there are lots of ways to interconnect computers like using coaxial wires, optical fibers, and even by means of power lines. But as technology advances there are better ways to do this like wireless technology which include Bluetooth or Wi-Fi.
