Collision is a problem occurring when two workstations (computer connected through LAN) sends data simultaneously, id is corrected with CSMA/CD and Token technology.

Why not asynchronous?

Sehar said:   1 decade ago
Why collision is right answer? according to physics rule it might be right but its still confusing to me.

Collisions are a condition that arises when two or more data stations attempt to transmit at the same time over a shared channel, or when two data stations attempt to transmit at the same time in a half duplex communication link. A contention based channel access (multiple access) protocol is a protocol where data packet collisions may occur.

What is the difference between contention and collision?

Neel said:   1 decade ago
Collision is not the condition used to transmit two packets over a medium at the same time.

Question is asked in wrong way. It should be:

Which of the following condition when two packets transmitted over a medium at the same time?

Ans: Collision.

I think synchronous is correct answer because same time has been mentioned in it.

Meena V C said:   9 years ago
Yeah. Collision is the right answer because traffic occurs when two packets travel at a same time over the medium.

The answer should be option A contention as condition is used to transmit two packets over a medium at the same time is contention or Aloha in Random access method.

Contention is the answer. The contention is the condition when two stations try to send packet simultaneously.
