Network, so what is it ? today we are gonna talk about computer network, that what is it ? what is it their advantage and disadvantage. and what is collision.
network is used in many company to send and receive data . it is very useful to transfer large amount of data.
What is Network?
Two or more devices are connected in such a way that the data and information that can be shared with the media is called network.
Advantages And Disadvantages of a Network
| Advantage | Disadvantage |
| Hardware can be shared Data or information can be shared Central administrators can be used Permission or security can be givenCan be shared in any networkProtocols can used | · If the server fails in the network, the whole network stops. |
What is collision?
Collision gives data on one or two PCs in the network and the data that happens on the same time is collision with one other, it is called collision. Data collapses when a collision occurs within the network
What is a baseband line?
A signalling technology that sends digital signals over a single frequency as discrete electrical pulses.baseband system ’s entire bandwidth has only one data to carry and it is generally less than the broadband transmission system’s available bandwidth
In This line of communication only one way of receiving or giving of data is happen
What is the broadband line?
The Broadband transmission employs analog signals which include optical or electromagnetic wave form of signal.To send multiple signals simultaneously, signals are sent into different frequency. frequency spectrum was divided into several sections of bandwidth to make possible frequency division multiplexing. Distinct channels can send different frequency signals simultaneously.
The broadband line is a line in which data can be sent at one time and can also be received
