What are the benefits advantages of addressing modes?
The addressing mode specifies a rule for interpreting or modifying the address field of the instruction before the operand is actually executed. The 8086 memory addressing modes provide flexible access to memory, allowing you to easily access variables, arrays, records, pointers, and other complex data types.

What is difference between direct and indirect addressing mode?
Direct addressing provides the full address of the main memory in the instruction, where the is stored. On the other hand, in indirect addressing mode, the address is stored at the address field of the instruction.
What is direct mode in computer?
Direct mode, also known as immediate mode is a computing term referring to the input of textual commands outside the context of a program. The command would be executed immediately and the results printed on screen, in contrast to programming mode where nothing would be executed until a specific command was given.
What is direct command?
In the “direct command” you flash your command to the mind of the other person, mentally, of course, but in exactly the same way that you would make an actual command by spoken words, if the conditions admitted of the same.
What do you mean by addressing mode?
Addressing modes are an aspect of the instruction set architecture in most central processing unit (CPU) designs. An addressing mode specifies how to calculate the effective memory address of an operand by using information held in registers and/or constants contained within a machine instruction or elsewhere.
