Remember CSMA/CA
Full name: Carrier Sense Multiple Access with Collision Avoidance
Memory aid: Wireless clients Cannot reliably detect every collision, so they Avoid them.
Avoidance reduces collisions but does not guarantee none occur.

CSMA/CA — Carrier Sense Multiple Access with Collision Avoidance
Coordinates wireless medium access by sensing and attempting to avoid collisions.
Why learn CSMA/CA — Carrier Sense Multiple Access with Collision Avoidance?
Coordinates wireless medium access by sensing and attempting to avoid collisions.
Where it came from
Avoidance reduces collisions but does not guarantee none occur.
- Memory aid (a learning cue, not the expansion): Wireless clients Cannot reliably detect every collision, so they Avoid them.
