Core Hardware Quiz #11
Serial Ports transmit data _____ .
Answer: B - One bit at a time
Explanation: Well, right off the bat you can cancel out A and C because there is only one answer to this question and A and C are the same amount of data! Normal RS-232 communication is serial standard and transmits at 1 single bit at a time. Parallel totally revolutionized this transfer because of it's ability to transfer 1 bit at a time over 8 "parallel" cables. Hence the name. So, parallel would be the connection that transfers 8 bits at one time.
Tidbit: Did you know that all networking communication is serial???? Well, it is until the data gets to the network card itself. From there on, it's parallel!!!
