Is a multiplexer a register?

Not all the registers have multiplexers. But parallel to serial SR’s have. Multiplexers are just digital blocks and widely used in digital systems. So, multiplexers are not avoided to use in register or in any digital block at all.

What is the difference between multiplexer and decoder?

Multiplexer is a data selector which takes several inputs and gives a single output.In multiplexer we have 2n input lines and 1 output lines where n is the number of selection lines. 2. Decoder is a logic circuit which n input lines into m output lines.

What is the difference between register and memory?

Registers hold the operands or instruction that CPU is currently processing. Memory holds the instructions and the data that the currently executing program in CPU requires.

What is buffer register in digital electronics?

buffer register A storage location or device for the temporary storage of information during the process of writing to or reading from main memory. It generally has a capacity equivalent to one byte or one word.

What is multiplexer and demultiplexer explain it?

A Multiplexer is a circuit that accept many inputs but gives only one output. A Demultiplexer functions exactly in the reverse way of a multiplexer i.e., a demultiplexer accepts only one input and gives many outputs. Generally, multiplexer and demultiplexer are used together in many communication systems.

What is the multiplexer and demultiplexer?

A multiplexer (Mux) is a combinational circuit that uses several data inputs to generate a single output. A demultiplexer (Demux) is also a combinational circuit that uses single input that can be directed throughout several outputs.

What is meant by multiplexer and demultiplexer?

A Multiplexer is a circuit that accept many inputs but gives only one output. A Demultiplexer functions exactly in the reverse way of a multiplexer i.e., a demultiplexer accepts only one input and gives many outputs.
