what is instruction length and what is instruction format and what is program length and what is the difference among them
the number of bits required to represent an instruction of a cpu is known as length of the instruction or known as instruction.
In the 8086 microprocessor, the maximum length of an instruction is 6 bytes. This includes the opcode, any necessary prefixes, and operands. The architecture allows for complex addressing modes, which can contribute to the instruction length, but the limit remains at 6 bytes for any single instruction.

The Instruction Location Counter is a variable inside of the assembler. While the Program Counter is a register. The PC solely keeps track of the next instruction in a program, ILC increments by each instruction's operand length.
One of its advantage is to save storage space.
When designing the length of an instruction, several factors should be considered: the complexity of the operation being performed, the need for efficient encoding to minimize memory usage, and the architecture of the processor, which may favor fixed or variable-length instructions. Additionally, the target application and overall system performance, including execution speed and pipeline efficiency, play crucial roles in determining instruction length. Balancing these factors ensures optimal performance and ease of use in software development.
