What is Tree topology?

The tree topology is the combination of star and the bus topology. It combines the multiple star topologies into one bus topology.

What is Mesh Topology?

In Mesh topology all the system is connected which each other. It is more reliable than the other networks but it is very expensive if one system collapses other network still work.

What is Star topology?

In star topology all the computers are connected through the central device which is called HUB. We can increase computers without stopping the network if one computer stops working others computers on network still work but if the HUB stops working then the network will be collapse.

What is Bus topology?

In bus topology all the computers are connected to the middle wire which is called the backbone of the network. The establishment of this network is very simple and its cheap if one system is down the reaming systems will work but the disadvantage is if the middle wire (back bone) break then the whole network will collapse.

What is Ring topology?

In ring topology all the computers are connected in a series and the last computer is connected to the first computer like a ring. The advantage is it is simple to connect but disadvantage is that if any link or computer is down the whole network will down.

How many topologies are there?

There are different topologies. In which the most common topologies are below.
Like Ring topology,
 bus topology ,
Star topology
Mesh topology
Tree topology

What do you mean by topology?

To form a computer network is called Topology. It is also the arrangement of nodes which are connected together .Topologies are used for share the resources of a computer like printers, data etc

What is network in computers?

When different computers connect together to share the data it is called network computers. Many organizations are connected through the computer networks. These make the business easy.Two or more computer connect together and share their resources is also called Network.

What is personel Computer?

A computer which is used by one person is called personal computer. It is also called PC .

Difference between computer science and computer engineering?

Computer science is a knowledge about computers. It includes the software and other utilities of software.
Where computer engineering is knowledge study of computer software as well as computer hardware.
Software are those which are not touchable like Multimedia software, Windows etc where Hardware are the devices which are touchable like monitor, printer etc .

Computer Basic parts

There are many basic parts of a computer like Monitor , Keyboard , CPU , Mouse etc .Some parts are called input device and some are called output device . the devices from which we entered the data is called input device like Keyboard , mouse scanner .The devices which give us out put are called output devices like Monitor/LCE/LED, printer, plotters etc


What is Computer ?

A computer is an electronic device to which w give instructions and it processess the instructions and give us the desired result. The word computer come from the word compute which means' to calculate' so computer is a machine which was used in past as calculater.
