Twisted pair
A cable composed of two small insulated conductors twisted together without a common covering. Also known as copper pair. Twisted pair is the ordinary copper wire that connects home and many business computers to the telephone company. To reduce crosstalk or electromagnetic induction between pairs of wires, two insulated copper wires are twisted around each other. Each connection on twisted pair requires both wires.

Coaxial Cable Coaxial cable is the kind of copper cable used by cable TV companies between the community antenna and user homes and businesses.The inner conductor is typically a straight wire, either solid or stranded and the outer conductor is typically a shield that might be braided or a foil.A cable consisting of a conducting outer metal tube that encloses and is insulated from a central conducting core, used primarily for the transmission of high-frequency signals. Also called coaxial line.

Fiber Optic Cable

An optical fiber cable is a cable containing one or more optical fiber. The optical fiber elements are typically individually coated with plastic layers and contained in a protective tube suitable for the environment where the cable will be deployed. Fiber Optic Network Cables including mutlimode and singlemode simplex and duplex fiber optic cable in bulk, FC, MTRJ, SC, ST and LC fiber terminations available in various lengths. Fiber converters also available.

Node

In a network, a node is a connection point, either a redistribution point or an end point for data transmissions. In general, a node has programmed or engineered capability to recognize and process or forward transmissions to other nodes.

Client

A client is the requesting program or user in a client/server relationship. For example, the user of a Web browser is effectively making client requests for pages from servers all over the Web. The browser itself is a client in its relationship with the computer that is getting and returning the requested HTML file. The computer handling the request and sending back the HTML file is a server.

Server
A server is an application running on a computer that delivers a service. For example, a web server will deliver web pages when requested by a browser. The way a server and a client dialogs is called a protocol. For instance, HTTP is the protocol used between a browser and a web server.

Hub

A common connection point for devices in a network. Hubs are commonly used to connect segment of a LAN. A hub contains multiple ports. When a packet arrives at one port, it is copied to the other ports so that all segments of the LAN can see all packets.
Network Interface Card (NIC)


A network interface card (NIC) is a computer circuit board or card that is installed in a computer so that it can be connected to a network. Personal computers and workstations on a local area network (LAN) typically contain a network interface card specifically designed for the LAN transmission technology, such as Ethernet or Token Ring. Network interface cards provide a dedicated, full-time connection to a network. Most home and portable computers connect to the Internet through as-needed dial-up connection. The modem provides the connection interface to the Internet service provider.

Network Operating System (NOS)

Network operating system (NOS) is a computer operating system that is designed primarily to support workstation or personal space older terminal that are connected on a local area network (LAN). Contains components and programs that allow a computer on a network to serve requests from other computer for data and provide access to other resources such as printer and file systems.
Host Computer
Main or controlling computer connected to other computers or terminals to which it provides date or computing service via a network. It is similar to a server. In the modern, every computer is a peer and also a host to every other computer connected to the network. The name reflects the biological relationship between the host and parasites.
Network Manager
Operation deals with keeping the network up and running smoothly. It includes monitoring the network to spot problems as soon as possible, ideally before users are affected. Administration deals with keeping track of resources in the network and how they are assigned. It includes all the "housekeeping" that is necessary to keep the network under control. Maintenance is concerned with performing repairs and upgrades. Maintenance also involves corrective and preventive measures to make the managed network run "better", such as adjusting device configuration parameters.
