Routing and switching are the basic functions of network communication. ... The function of Switching is to switch data packets between devices on the same network (or same LAN - Local Area Network). The function of Routing is to Route packets between different networks (between different LANs - Local Area Networks).

A wireless network is a computer network that uses wireless data connections between network nodes. ... Examples of wireless networks include cell phone networks, wireless local area networks (WLANs), wireless sensor networks, satellite communication networks, and terrestrial microwave networks.

Mainly specialized authentication policies are used to scrutinize network traffic. A LAN also requires internal security to avoid threats such as email based viruses or viruses from downloading a file from an illegitimate source.

In its simplest term, it is a set of rules and configurations designed to protect the integrity, confidentiality and accessibility of computer networks and data using both software and hardware technologies.

A structured cabling system is a complete system of cabling and associated hardware, which provides a comprehensive telecommunications infrastructure. This infrastructure serves a wide range of uses, such as to provide telephone service or transmit data through a computer network. It should not be device dependent.
