OR

Why do we need computer networks?

TCP/IP stands for Transmission Control Protocol / Internet Protocol.
TCP/IP is a set of rules and regulation (protocols) governing communications among all computers on the Internet. More specifically, TCP/IP dictates how information should be packaged (turned into bundles of information called packets), sent, and received, as well as how to get to its right destination. TCP/IP is a combination of two separate protocols: TCP (Transmission Control Protocol) and IP (Internet Protocol).
The Internet Protocol standard dictates the logistics of packets sent out over networks; it tells packets where to go and how to get there.
The Transmission Control Protocol is responsible for ensuring the reliable transmission of data across Internet-connected networks. TCP checks packets for errors and submits requests for retransmissions if any are found.
OR
(i) Networks enable resource sharing across the globe.
(ii) Networks provide high reliability by having alternate copies of data. Presence of multiple CPUs means that if one goes down, the others may be able to take over its task. This ability to work in the face of hardware problems is of at most importance in military, banking, air traffic control, nuclear reactor safety, etc.
(iii) Networks enable a client/server model with clients as small computers, one per user, with data kept on one or more shared file server machines. e.g. Software installation can be done on server and this can save cost of buying license for every machine.
