Functional Units of Computer

Introduction to Functional Units of Computer

In order to perform the operations that mentioned above the computer allocates the work between its several functional units. The computer system is categorized into three separate units for its operation. They are as follow:

1) Arithmetic logical unit, (ALU)

2) Control unit, (CU)

3) Central processing unit (CPU)

ARITHMETIC LOGICAL UNIT (ALU)

After that you enter data by the input device the data is stored in the primary storage unit. The real processing of the data and instruction are carried out through Arithmetic Logical Unit. The main operations carried out through the ALU are addition, division, subtraction, multiplication, logic and comparison. Data is transmitted to ALU (Arithmetic Logical Unit) from storage unit while needed. Later than processing the output is return back to storage unit for additional processing or getting stored.

CONTROL UNIT (CU)

The component that is emerges next to ALU is the Control Unit that acts like the supervisor seeing that things are completed in proper fashion. The control unit ascertains the sequence where computer programs and instructions are executed. Things such as processing of programs stored in the main memory, interpretation of the instructions and issuing of signals for other computer's units to execute them. CU also works as a switch board operator while various users access the computer concurrently. Thus it coordinates the activities of peripheral equipment of computer as they carry out the input and output. So it is the manager of all operations mentioned in the preceding section.

CENTRAL PROCESSING UNIT (CPU)

The CU and ALU the of a computer system are jointly termed as the central processing unit (CPU). You might call central processing unit (CPU) as the brain of a computer system. It is just similar to the brain that takes all main decisions, carries out all sorts of calculations and directs dissimilar parts of the computer functions through activating and controlling the operations.

CPU (central processing unit) or processor is an electronic circuit which can execute computer programs that are actually sets of instructions. This word has been in employ in the computer industry at least from the early 1960s. The type, design and implementation of CPUs (central processing units) have changed dramatically since the earliest examples, but their fundamental operation stays much similar.

A. The CPU (central processing unit) executes a series of instructions by looping by an instruction cycle.

B. The speed of the instruction cycle is controlled through the CPU's clock.

C. The CPU executes computer instructions

D. well-liked CPU's: Intel-Pentium, AMD, Power PC

E. It is on a chip termed as the microprocessor.
