Why not synchronous it is also valid along with time bound ?

Pavankumar said: (Nov 10, 2011)  
Why not synchronous?

Blossom said: (Nov 16, 2011)  
Because one packet can be transmitted at a time.

Why collision is right answer?

Why collision?

Kingkalai said: (Mar 3, 2012)  
A problem will arise when two packets are send together.

I think sout synchronous is right answer because without synchronization, collision will occur which leads to loss of information. Synchronous condition is neccessary to trasmit 2 packets simutaneously. :).

Vikas Kumar Singh said: (Oct 12, 2012)  
Yeah synchronous is the right answer.

Focused on question two packets are send at same time that's means chance of collision here and they should manage by collision occuring condition so. Right one is collision.

While transmitting two packets avoiding collision b/w them is more important. So collision is the correct answer.

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: (Sep 26, 2013)  
Why collision is right answer? according to physics rule it might be right but its still confusing to me.

Hitesh said: (Nov 8, 2013)  
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.

Spoorthi said: (Jul 2, 2015)  
What is the difference between contention and collision?

Neel said: (Aug 17, 2015)  
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.

Akhtar Ali Bhatti said: (Jan 2, 2016)  
I think synchronous is correct answer because same time has been mentioned in it.

Meena V C said: (Mar 14, 2016)  
Yeah. Collision is the right answer because traffic occurs when two packets travel at a same time over the medium.

Dimple said: (Apr 25, 2016)  
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.

Usha said: (Aug 30, 2016)  
Contention is the answer. The contention is the condition when two stations try to send packet simultaneously.

Saumo said: (Apr 16, 2017)  
I think Synchronous is right option.

Radhika said: (Jun 23, 2018)  
Synchronous is correct I think.

Priya said: (Jul 27, 2018)  
Contention must be the correct answer.

G. Altamas said: (May 21, 2019)  
Synchronous must be the correct answer.
