Instruction Cache - Used for storing instructions that are frequently used Instruction Register - Part of CPU's control unit that stores the instruction currently being executed Instruction Opcode - It is the portion of a machine language instruction that specifies the operation to be performed Translation Lookaside Buffer - It is a memory cache that stores recent translations of virtual memory to physical addresses for faster access. So, all the above except Instruction Opcode are memories. Thus, C is the correct choice. Please comment below if you find anything wrong in the above post.

Instruction Opcode
Instruction Opcode is not a form of memory. It is a part of the instruction set of a computer's machine language. It is a code that specifies the operation to be performed by the processor.

Explanation:

Instruction Cache:
- Instruction cache is a type of memory that stores frequently accessed instructions for faster execution by the processor.
- It helps reduce the time taken to fetch instructions from the main memory.

Instruction Register:
- Instruction register is a part of the processor that holds the current instruction being executed.
- It is a small storage location within the CPU.

Translation Lookaside Buffer (TLB):
- TLB is a memory cache that stores the mapping between virtual memory addresses and physical memory addresses.
- It is used to accelerate the translation of virtual addresses to physical addresses during memory access.

Conclusion:
Instruction Opcode is not a form of memory because it is a part of the instruction set and does not store data or instructions like the other components mentioned above. It is used to specify the operation to be performed by the processor and is not involved in memory storage or retrieval.
