Networking

Network, is a collection of computers and other hardware components interconnected by communication channels that allow sharing of resources and information. Where at least one process in one device is able to send/receive data to/from at least one process residing in a remote device, then the two devices are said to be in a network. Simply, more than one computer interconnected through a communication medium for information interchange is called a computer.

Active Networking:-

Active networking is a communication pattern that allows packets flowing through a telecommunications network to dynamically modify the operation of the network.

Passive Networking:-

A passive optical network is a form of Fiber-optic access network Downstream signals are broadcasted to all premises sharing multiple fibers. Encryption event eavesdropping. Upstream signals are combined using a Multiple access protocol, usually time diversion multiple access (TDMA). The OLTs "range" the ONUs in order to provide time slot assignments for upstream communication.
