Communication and Network

Modulation :-

        Modulation is the process of changeable properties of high frequency periodic waveform with a regulating signal which contains information to be transmitted. It can be used to alternating current, to direct current, and to optical signals.









Demodulation :-

        Demodulation is the opposite of modulation. It is the act of extracting the original data-bearing signal from a regulating carrier wave. It converts analog signals back into digital signals. It is also called detection.

Bandwidth :-

        Bandwidth is the range of frequencies used to transmit signals. It is a range within a band of wavelengths. It has a transmission capacity of a computer network or other telecommunication system.

TCP/IP :-

        TCP/IP is abbreviated as Transmission Control Protocol / Internet Protocol. They are a set of protocols used to take control the connection of the systems in the computer to the Internet. They are the basic language of the Internet.

Node :-

        Node is a connection point used to build linked data structures. For example, a computer-based representations of the graph. It is where two or more circuit elements meet.

Client :-

        A client runs on a personal computer or workstation and accesses a remote service on a server by way of a network. It is a node that asks and uses resources available from other nodes.

Server :-

        A server is a computer program that has been assigned to hold large quantities of data and stream it to the users who requested them. It manages access to a consolidated resource or service in a network.

Network Operating System :-

        A network operating system is also known as NOS. It is an operating system that holds components and programs that allows a computer on a network to serve requests from other computers for information. It controls the computer systems, peripherals and the communication between them.

Network Administrator :-

        A network administrator is a computer professional that is responsible for maintaining the computer hardware and software comprises a computer network. In other words, a network administrator is responsible for efficient network operations and implementation of all networks.
