Task 1.1 and 1.2, Significant features of Local Area Networks.
A
Describe in detail peer to peer.

Peers are computer networks that are connected to each other through the internet. Files can be shared directly between systems without the need of a central server, which makes each computer on a p2p system its own client as well as a file server. A P2P (peer to peer) network requires only that you have an internet connection and P2P software such as, Kazaa , LimeWire, or bearshare.
When a P2P is connected it allows you to search for files on other peoples computers, while at the same time allows other users on the network to access yours that are typically assigned onto a single folder that you have designated to share.

Because data has to pass through each device the performance can be slower than other networks topologies. And if one device is off or if the cable breaks, the entire network fails.

Describe Token Passing.

Token passing: It is channel access method in which a signal called a token (a series of bits) is passed between 2 nodes that grants permission to the nodes to communicate. When its function is finished the device passes the token along to the next device in the topology. In the protocol there are system rules that manage how long a device may keep the token, how long it may transmit for and if there is a token circulating, how to generate one.

Describe CSMA/CD: stands for Carrier Sense Multiple Access/Collision Detection.

Its function is to determine how network devices respond when two devices attempt to use the same data channel simultaneously (collision detection). It is a method that is used by shared networks like the Ethernet to manage access to the network. CSMA/CD monitors traffic on lines of participating channels. If a transmission is not taking place at the time on a particular channel, it is allowed to transmit. If two stations attempt to transmit at the same time, it causes a collision which is detected by the participating channels. After some time interval, the channels that collided attempt to transmit
