Question:
How do switch buffers affect network performance?
- They provide error checking on the data received.
- They store frames received, thus preventing premature frame discarding when network congestion occurs.
- They provide extra memory for a particular port if autonegotiation of speed or duplex fails.
- They hold data temporarily when a collision occurs until normal data transmission resumes.
Explanation: Switches have large frame buffers that allow data waiting to be transmitted to be stored so the data will not be dropped. This feature is beneficial especially if the incoming traffic is from a faster port than the egress port used for transmitting.
