Introduction of computer Networking
In its most basic form, a network is two or more computers that are connected with a communications line for purposes of sharing resources. so, if two computers connect to each other over a telephone line or through a piece of cable or even through a wireless connection and the users are able to access ad share files and peripheral devices on the other computers, a network is formed. the individual systems must be connected through a physical pathway (called the transmission medium). All systems on the physical pathway must follow a set of common communication rules for data to arrive at its intended destination; and for the sending and receiving systems to understand each other. The rules that govern computer communication are called protocols.
Networking must have the following:
- Something to share (data)
- A physical pathway (transmission medium)
- Rules of communication (protocols)
