Fill in the blank with the appropriate port name.
___________ is a 2-row and 9-pin male D port used to connect to switches and routers

Answer: Serial port
Explanation:
Serial port is a 2-row and 9-pin male D port used to connect to switches and routers for configuring
them in a network. 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 fact 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.
