This document provides an overview of basic networking concepts, defining a network as a group of connected devices for data exchange. Key topics include nodes, client-server architecture, IP addresses, switches, and routers, which are essential for connecting and managing network traffic. It also offers an invitation to learn more about networking through TCCI's resources.

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.
Basic of Network contains node, Client-server, Ip Address, Switch, Router
-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

2. -Some networks also provide names that humans can more easily remember than numbers.
Example: www.javasoft.com, corresponding to the above numeric address. NIC addr1 NIC
addrN NIC addr2 …
Clients and servers—how services such as e-mail and web pages connect using networks.
IP addresses—how devices on a network can be found. Network hubs, switches and cables—
the hardware building blocks of any network.
Switches
Switches are the foundation of most business networks. A switch acts as a controller,
connecting computers, printers, and servers to a network in a building or a campus.
Routers
Routers connect multiple networks together. They also connect computers on those networks
to the Internet.
Routers and firewalls—how to organize and control the flow of traffic on a network.
