Explanation
Explanation: Answer options B and C are correct. Serial port is the primary means for connecting modems and mouse to a computer. There are two types of serial port connectors, 9-pin and 25-pin. The word serial refers to the that data is sent in series, one bit at a time, over a single wire. This design is significantly slower than sending 8 bits at a time via a parallel channel, but serial signals can travel much farther without degradation.
