How many bits are used in three address instruction formats?
Correct answer: D. Twenty-Two bits
- A. Four bits
- B. Ten bits
- C. Sixteen bits
- D. Twenty-Two bits
Explanation
The answer cannot be definitively determined without additional information about the specific three-address instruction format being used. Here's why each option is inconclusive.The number of bits required in a three-address instruction format depends on several factors:Opcode size: The opcode identifies the operation to be performed. More complex instruction sets may require more bits for the opcode.Address size: The size of the memory addresses or register identifiers will determine how many bits are needed to specify each operand location.Addressing mode size: Different addressing modes (e.g., register direct, immediate, indirect) may have varying bit requirements to encode the necessary information.Without knowing the specifics of the instruction format, it's impossible to pinpoint an exact bit count. However, sixteen to twenty-two bits is a more realistic range compared to four or ten bits.

About Hardware and Software
Hardware includes the physical components of a computer, such as the CPU, motherboard, registers, memory, storage devices and peripheral equipment. Software covers system software, application software, utilities, drivers and firmware, with attention to how the operating system manages hardware and how software differs from the physical equipment it controls.
