Q. Describe Data Transfer Instructions?

These instructions transfer data from one location in the computer to another location without altering the data content. Most common transfers are between:

• Processor registers and I/O
• Processor registers and memory
• Processor registers themselves

These instructions require:

• Location of destination and source operands
• Mode of addressing for every operand. Given below is a table that lists eight data transfer instructions with their mnemonic symbols. These symbols are used just for understanding purpose, the actual instructions are binary. Various computers may use different mnemonic for the same instruction.
