Glossary

Here you will find introduction to network glossary, LAN/WAN terminology, telecommunication terminology such as Router, bandwidth, wireless communication, hubs, modems, multiplexer and topology. You will be able to find different terms such as Hubs, Router, Switch, Ethernet, Raid, coaxial cable, bridge, fiber optic, internet, infrared, email, repeater, segment, thick-net etc and many other terms.

Communication Devices

Introduction to the Network Communication Devices

In this tutorial you will learn get the basic introduction to network devices such as NIC {Network Interface control } adapters, Routers, Hubs, Switches, Modems, communication cables,LAN/WAN Routers, Gateway and other Devices. A Network is consists of a larger number of the communication devices. The simplest device that is used in the communication is the NIC adapter which is attached with the every computer in a network. If you want to build a LAN, you will need to have computers, hubs, switches, network adapters, UTP/STP cables, routers, internal/external modems, connectors, cable testers and clipping tool.

About of Networking Layers

OSI 7 Layers Reference Model

Here you will learn OSI Model Layer Introduction, overview of the 7 OSI reference model,application, presentation, session, transport, network and physical layers. If you want to remember the sequence of the OSI layers model name then the following two sentences can help you a lot for this purpose.“All People Seems To Need Data Processing”. Open Systems Interconnection (OSI) model is developed by ISO (International organization for standardization) in 1984. OSI reference model is a logical framework for standards for the network communication.

OSI reference model is now considered as a primary standard for inter networking and inter computing. Today many network communication protocols are based on the standards of OSI model. In the OSI model the network/data communication is defined into seven layers.
