Communication and network

Twisted-pair

Twisted pair cabling is a type of wiring in which two conductors are twisted together.

The two wires carry equal and opposite signals and the destination detects the difference between the two.

Noise sources introduce signals into the wires by coupling of electric or magnetic fields.

Coaxial cable

Coaxial cable is an electrical cable with an inner conductor surrounded by a tubular insulating layer typically of a flexible material. The term coaxial comes from the inner conductor.

Coaxial cable is used as a transmission line for radio frequency signals.

Fiber optic cable

An optical fiber cable is a cable containing one or more optical fibers. fiber elements are typically individually coated with plastic layers.

Network Term

Node

Node is a connection point, either a redistribution point or a communication endpoint. node depends on the network and protocol layer.

A physical network node is an active electronic device that is attached to a network, and is capable of sending, receiving, or forwarding information.

Client

Client-server computing or networking is a distributed application architecture that partitions tasks or work loads between service.

Server

A network server is a computer designed to process requests and deliver data to other computers over a local network or the Internet. A server in this case could refer to the program that is managing resources rather than the entire computer.

Hub

A network hub or repeater hub is a device for connecting multiple twisted pair or fiber optic.Hubs are commonly used to connect segments of a LAN.

Network Interface Card

A wireless network interface controller (WNIC) is a network card which connects to a radio-based computer network, unlike a regular network interface controller (NIC) which connects to a wire-based network such as token ring or ethernet. This port accommodates an Ethernet cable, which resembles a thicker version of a standard telephone line.

Network Operating system

A networking operating system is an operating system that contains components and programs that allow a computer on a network to serve requests from other computer. It is also an operating system that includes special functions for connecting computers and devices into a local-area network.

Distributed Processing

A system consisting of a network of microcomputers performing certain functions and linked with a main computer used for more complex tasks. The computers interact with each other in order to achieve a common goal. . It also refers to any of a variety of computer systems that use more than one computer, or processor, to run an application.

Host Computer

Controlling computer connected to other computers or terminals to which it provides data or computing services via a network. The system that contains the data is called the host, while the computer at which the user sits is called the remote terminal.

Network Manager

NetworkManager is a software utility aimed at simplifying the use of computer networks on Linux and other Unix-like operating systems. A service which manages connections and reports network changes, and a graphical desktop applet which allows the user to manipulate network connections.
