The instruction unit (decodes and sends commands to alu of the cpu)
Instruction fetch is the process by which the CPU retrieves instructions from memory in order to execute them. The CPU fetches instructions one at a time, and these instructions are then decoded and executed as part of the program being run. Efficient instruction fetching is important for the overall performance of a computer system.
The only part of a program a computer understands is each instruction as it is presented to the instruction decoder. It understands the instruction by an intricately designed logic circuit and/or microprogram configured by a human computer hardware engineer. This engineer had to fully understand the instruction set of the machine to teach it to understand the instructions one at a time at runtime.
In programming, an instruction that directs the computer to another part of the program based on the results of a compare.

In the context of the 8086 microprocessor, the prefetch queue is a 6-byte high-speed queue that stores the next instruction to be executed. This helps improve performance by fetching instructions in advance and storing them in the queue. When the CPU is ready to execute the next instruction, it can quickly access it from the prefetch queue without having to wait for the instruction to be fetched from memory.
A microprocessor is the main part of a computer. It is the engine of a computer that has been created on only one chip. It stores data, moves data from one memory location to another, communicates with other parts of the computer, can do computations, and is controlled by assembly language instructions, that it fetches from some memory.
When an instruction is read from memory, it is called "fetching." This process is part of the instruction cycle, where the Central Processing Unit (CPU) retrieves an instruction from memory to execute. Fetching is the initial step, followed by decoding and executing the instruction. This sequence is essential for the proper functioning of a computer's processing capabilities.
The Hard Drive is the main storage unit in a normal, desktop computer. This is the only internal component in a standard computer that has information when the machine is turned off (all your saved files, the operating system (such as Windows), etc). There are other components (such as RAM, or Random Access Memory) that store data, but this usually serves a special purpose, or is only at run-time.
Instruction is a noun.
The part of the computer that processes data is called the processor or processing unit. Older computers had a Central Processing Unit (CPU) . Modern machines often have more than one processing unit. The processor fetches and decodes the instructions that make up the program as well as doing the arithmetical operations.
CPU - trust me I already took the test! :)
