Networking

A network can be defined as a group of computers and other devices connected in some ways so as to be able to exchange data.

A network must provide connectivity among a set of computers. While some networks limit the number of connected machines, others grow as large as a global wide area network.

Naturally, computer networks are expected to perform well, and it’s vital to understand the factors that can impact network performance. Network performance is measured by bandwidth and latency. A network’s bandwidth is the number of bits that can be transmitted over the network in a certain period of time. Latency is how long it takes a message to travel from one end of a network to the other and is measured in time. Equations found in this chapter can help you properly assess the performance of your computer LAN or WAN network.

Each of the devices on the network can be thought of as a node; each node has a unique address.
Addresses are numeric quantities that are easy for computers to work with, but not for humans to remember.
Example: 204.160.241.98

Computer networking are commonly  at both the undergraduate and graduate levels through certificate and degree programs in information systems, computer networking technology .Basic networking topics (LANs, WANs, Ethernet, Frame-Relay and so on).
