Multiplexer(Multiplexing).In telecommunications and computer networks,multiplexing(also known as muxing) is a method by which multiple analog message signals or digital data streams are combined into one signal over a shared medium.
Depends, is the device serial or parallel?

Serial
A serial port is neither strictly an input device nor an output device; rather, it is a communication interface that can handle both input and output data. It allows for the transmission of data between a computer and peripheral devices, such as modems or printers. Depending on the direction of data flow, a serial port can function as an input, output, or both simultaneously.
Serial ports only allow one device to send and one device to receive at a time, where a parallel port can send and receive data at the same time.
No. VGA port is not either serial or parallel port. It is a different interface. If you need a serial output, you need a VGA to serial converter.
The best way is to attach a serial port using device to the serial port of your computer and use your preferred program to send data to the device
true.
A 4-bit serial-in parallel-out (SIPO) shift register consists of four flip-flops connected in series, where data is input serially into the first flip-flop. As each clock pulse is applied, the data shifts through the flip-flops, moving from one to the next. Once all four bits are shifted in, they can be read out in parallel from the output of each flip-flop simultaneously. This allows for the serial input data to be converted into a parallel output format.
Neither. A computer case is just a box to hold the parts of a computer. It provides no form of communication itself.
