What are SIFS and DIFS, and why are they needed?

What will be an ideal response?


The wireless standard defines timing parameters as follows:
? SIFS (Short Inter-Frame Space) of 10 µsec
? DIFS (Distributed Inter-Frame Space) of 50 µsec
The SIFS parameter defines how long a receiving station waits before sending an ACK or other
response; the DIFS parameter, which is equal to SIFS plus two Slot Times, defines how long a channel
must be idle before a station can attempt transmission.
