NETWORK TOPOLOGY:

The arrangement or layout of computers in a network is called network topology. In simple words we can say that the way computers and devices are connected in a network is called network topology. There are different types of network topology some of them discussed:

§ BUS TOPOLOGY

§ RING TOPOLOGY

§ STAR TOPOLOGY

§ MESH TOPOLOGY

BUS TOPOLOGY:

In this topology a main transmission line is laid down in the center of network and all the devices and computers are connected to each other. The physical line is called bus that is why this type of network is called bus network or bus topology. Data travel through the center line until it reaches the required device or computer. At both end of line there are terminators that terminate data when it reaches the destination. One of the computer acts as server in this topology. It is a low cost and easy to install network topology.

RING TOPOLOGY:

In ring topology each node is exactly connected to each other nodes on a network, forming a ring. In this type of topology data travels in one direction. When a computer sends data to the other device or a node it travel through entire ring until it reaches the destination. In this topology if one node is failed the whole ring is failed. For example if client 4 requests a file from the server the file will travel through the client 1, client 2 and client 3 then it will reach the destination client 4, hence the transfer is low.

STAR TOPOLOGY:

In star topology all devices and computers are connected to a central device like a router, switch or a hub, etc. data is sent to the central device which then sends out data to the desired host. In this topology if one device fails then the rest of the network is unaffected. On the other hand if central device breaks down the whole network crashes. For example, if a computer requests for the data the central device will locate the data and route that data to the required destination. It is very popular and most used topology. In this topology new nodes are very easy to install.

In star topology the central device can be a computer server or a simple device like switch, router, hub, bridge, NIC or dial up modem.

MESH TOPOLOGY:

In mesh topology each node is exactly connected to one or multiple other nodes on a network. In this topology all hosts can also be connected to each other which are known as full mesh. It is expensive and difficult to install and manage.

LAN (LOCAL AREA NETWORK);

LAN stands for local area network. It connects computers and devices in a limited geographical area such as home, school, computer laboratory and office. In LAN, computer share printers, storage devices and different programs with one another. A LAN is the simplest form of network. In LAN typically one transmission medium is used. Its speed ranges from 10 Mbps to 1Gbps.

COMMUNICATION:

The basic exchange of data/ information from one computer to another is known as data communication.

DATA:

In communication data is an entity that is sent and received over a computer network. It can be in the form of text, image, numbers, audio or video, etc.

DATA TRANSMISSION:

Sending data from one device to another device or a computer network is known as data transmission.
