Explanation / Answer

LAN

The local area network connects the computer hardware in a localized area. It is typically a wired connection that links computers and peripherals .A device connected in the LAN can access data from any other computer connected to the LAN. Users connected over a LAN can interact via messaging .LANs are used when you need much higher data rates then the telephone line connections.It can also be used to connect over telphone lines, satallites and radio waves to create a WAN

LAN metering

LAN metering is used to monitor real time the amount of time a particular software or an application has been used on a LAN network, or to detect unregistered/unlicensed software or to detect how many times or for how long functions in the software are used, and the user pays fees accordingly

Network types

Network types include

LAN, WAN, PAN, MAN

LAN : LAN will span a small distance usually in an office, school and they are owned , managed and controlled by a single organization

WAN:Wide area network It spans a larger physical distance and is a geographically dispersed collection of LANs.Routers are used to connect lans to wans.Most wans are not owned by single organization

MAN: A network which spans a physical area greater than a LAN but smaller than a WAN, such as a city. A MAN is typically owned and operated by a single entity such as a government body or large corporation.

Peer to Peer networks

A peer to peer network is a network in two or more users share content with each other over the network without the presence of a centralized server.Instead of having a server each computer acts as a server and stores files upon it
