Define Network?
-----A network is a set of devices connected by physical media links. A network is recursively is a connection of two or more nodes by a physical link or two or more networks connected by one or more nodes.

Define Bandwidth and Latency?
------Network performance is measured in Bandwidth (throughput) and Latency (Delay). Bandwidth of a network is given by the number of bits that can be transmitted over the network in a certain period of time. Latency corresponds to how long it t5akes a message to travel from one end off a network to the other. It is strictly measured in terms of time.
What is a gateway or Router?
-----A node that is connected to two or more networks is commonly called as router or Gateway. It generally forwards message from one network to another.
Define Routing
---- The
process of determining systematically hoe to forward messages toward
the destination nodes based on its address is called routing
Switches are used to connect multiple devices on
the same network within a building or campus. For example, a switch can
connect your computers, printers and servers, creating a network of
shared resources.
Routers, the second valuable component of your
networking basics, are used to tie multiple networks together. For
example, you would use a router to connect your networked computers to
the Internet and thereby share an Internet connection among many users.
What is the communication protocol?
In telecommunications, a communications protocol is a system of rules that allow two or more entities of a communications system to transmit information via any kind of variation of a physical quantity.
