Question

A binary message consisting of four bits was sent to you by a friend. The message was supposed to be ABAB. Unfortunately, your friend set the bit on the wire once every 2 seconds, but you read the wire once every second. Assuming that the first bit was sent and read at the same time, what message did you receive instead?

Answer 1

Answer: The correct answer is AABB. The bit rate can processed as fast as 8 bits per second. If you are reading every second and they are sending every 2 seconds, you may miss the 2nd bit and read this wrong.

The wire setting is set and will keep B, it will always keep the last setting on the wire.
