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.
The memory is a storage area that holds information. The processor processes, computes, and manipulates the information. Nowadays, the CPU does contain some information, but it is used for storing the most used information to make it easier for the CPU to access it. The RAM holds the programs while they are running, but the CPU is what runs the programs.

What is the difference between the read only memory and the random access memory in the internal memory unit of a computer?
R.O.M. :SoftwareR.A.M. :Hardware
Memory unit is a part of?
control unit too
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 fetches instructions from memory decodes them and process them?
Control Unit
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
Give the parts of the computer and ots functions?
ALU-->Arithamatic Logic Unit CU--->Control Unit MU--->Memory Unit
Different parts of the system unit or CPU?
diffent types of register, memory,ALU,timing and control unit
What are the parts of a microprocessor?
The microprocessor contains the CPU of a microcomputer. It is composed of the Arithmetic Logic Unit, Cache Memory (optional), Memory Management Unit (optional), Bus Interface Unit, Control Unit, Instruction Decoder, and Registers.
Difference between a CPU and control unit?
There is a big difference between these components. Both of them are part of central processor unit but control unit is responsible for generating control signals to all parts of cpu, to handle interrupts, to deal with registers etc. Arithmetic logic unit is part which does arithmetic and logic operations (for example, arithmetic operations are add,subtract,add with carry,subtract with carry,divide... and logic operations are AND,OR,XOR,NOT,NAND,NOR...).
