Question

Which type of interframe space provides the highest level of priority network function control over the medium for a short time period?

a) Short Interframe Space (SIFS)
b) Medium Interframe Space (IFS)
c) Long Interframe Space (LIFS)
d) Distributed Interframe Space (DIFS)

Answer 1

Short Interframe Space (SIFS) provides the highest level of priority network function control over the medium for a short time period.

Step-by-step explanation:

The type of interframe space that provides the highest level of priority network function control over the medium for a short time period is Short Interframe Space (SIFS).

SIFS is the shortest interframe space in the IEEE 802.11 standard and is used for high-priority network control messages. It allows the MAC layer to transmit such messages with minimal delay, giving them the highest priority over other frames or data.

For example, SIFS is used for ACK (Acknowledgment) frames, which are sent by the receiver to confirm the successful reception of a frame.
