“Computer Networks”, You probably hear that sound. Before begin to do the networking stuff let’s learn
what is networking?In its most basic form, a network is a communication system. Computer networks are systems made up of devices, their connections to one another, and the technologies used for information transfer.
Computer networks also known as information networks, play an integral role in today’s economy and society. A reliable connection to the internet, the world’s largest information network, is vital to governments, many businesses, organizations, and individuals. Learning how these connections occur and the requirements for connecting to the internet is the first step to understand information networks. The meaning of the “Network” word can simply describe as; A group of devices that can communicate with each other. Share the resources (such as hard disk. Files and folders) and access remote devices or other networks. So if we haven’t network such as we use today in our day to day life we won’t be abled to contact our friends even, meaning the networks are essential. The following picture will simply illustrate it. When we are going to learn about networking we have to make a foundation to understand the concepts of networking properly. Understanding the networking basics may be really boring because it is theoretical, anyway we have to follow that properly otherwise we will not understand them properly. So as a first step to build that foundation this article will describe about Basic Components of Network. Such as,
- Transmission Media
- NIC (Network Interface Card)
- Radio frequency waves often are used for LAN signaling. Radio frequencies can be transmitted across electrical cables(twisted pair or coaxial) or by using radio broadcast transmission.
- Microwaves are used to communicate between Earth Stations and satellites.
- Low power micro waves will be used for cellular phones.
