Control Unit
All computers follow instructions that are given to it in a program. These instructions are in a particular order in the program, and following them, and carrying them out, will mean that the computer has accomplished whatever task it was meant to do. Something in the computer has to manage the instructions and make sure that all the other parts of the processor do what they should be doing. This is the job of the control unit.
The control unit has three jobs:
- It has to decide which instruction to carry out next and then go and get it.
- It has to decipher the instruction, in other words it has to work out what needs to be done to carry the instruction out.
- It has to tell other parts of the processor what they should do so that the instruction will be carried out.
Memory Unit
The third part of the processor is where everything that the processor is going to use is stored. This includes all the program instructions and all the data needed to carry out those instructions. One of the jobs of the control unit is to be able to find the information stored there when it is to be used. The parts of the operating system, which the computer is using at the time, also need to be stored in memory.

Is memory unit parts of control unit?
No, the memory unit is not a part of the control unit. The memory unit is a separate component in a computer system that stores data and instructions temporarily or permanently. The control unit, on the other hand, is responsible for directing the operation of the processor and managing the flow of data between the CPU, memory, and other peripherals. While they work closely together, they serve distinct functions within the computer architecture.

What is the difference between microprocessor and computer?
a microprocessor is a small unit with memory inside the system unit while a computer is the combination of a monitor and a system unit
What is the purrpose of a control unit in a processor?
Control unit generates all the control signals like memory read signal,i/o read signal,memory write signal etc
What is the function of the control unit in the CPU?
The control unit provides the timing and control signal to all operations of microcomputer. It control the flow of data between microprocessor and memory and peripherals.
What is a S A M control unit?
A S A M control unit, or Serial Access Memory control unit, is a component in computing that manages the flow of data between the CPU and memory in systems that utilize serial access memory. It handles read and write operations, ensuring efficient data retrieval and storage. This unit is crucial in applications where memory access speed and efficiency are paramount, such as in embedded systems or digital signal processing. Its design can significantly impact the overall performance of the system.
Where do the control unit's instructions come from?
The control unit's instructions originate from the system's memory, specifically from the program stored in the main memory (RAM). These instructions are fetched from memory as part of the instruction cycle and then decoded and executed by the control unit to manage the operations of the CPU and coordinate with other components of the computer. Additionally, the control unit may also receive control signals from the CPU's internal registers and other hardware components.
What fetches instructions from memory decodes them and process them?

What are the three common components of computer?
central processing unit comprising of arithmetic logic unit and control unit, and RAM i.e.the internal memory
What is a control unit operation?
A control unit operation refers to the function of the control unit within a computer's central processing unit (CPU), which directs the execution of instructions in a program. It coordinates the activities of the CPU by sending control signals to other components, such as the arithmetic logic unit (ALU) and memory. The control unit interprets instructions from the program and manages the flow of data between the CPU, memory, and input/output devices, ensuring that operations are performed in the correct sequence. Overall, it acts as the "brain" of the CPU, orchestrating the entire computing process.
