Data processing, manipulation of data by a computer. It includes the conversion of raw data to machine-readable form, flow of data through the CPU and memory to output devices, and formatting or transformation of output. Any use of computers to perform defined operations on data can be included under data processing.

How A Computer process data Two components handle processing in a computer are the central processing unit or CPU, and the memory. Both are located on the motherboard which connects the CPU to all the other hardware devices. The CPU The CPU is the brain of the computer that is place where data is manipulated. Every CPU has at least two basic parts; these are the control unit and the arithmetic logic unit. •

• The control unit The duty of the control unit is manage all the computer’s resources. It seems to be a traffic cop directing the flow of data, logical hub of the computer. • The arithmetic logic unit Due to a lot of the processing which takes place involves comparing numbers or carrying out mathematical operations, the computer can perform only two types of operations. These are arithmetic operations and logical operations.

Arithmetic operations include addition, subtraction, multiplication, and division. Logical operations include comparisons, such as determining whether one number is equal to, greater than, or less than another number. Arithmetic logic unit or ALU is the second component of the CPU. It includes a group of registers – high-speed memory locations built directly into the CPU that are used to hold the data currently being processed.

For instance, the control unit might load two numbers from memory into the registers in the ALU. Then, it might tell The ALU to divide the two numbers (an arithmetic operation), or to see whether the numbers are equal (a logical operation).
Memory Memory is the area which can hold programs and the data being manipulated. This electronic memory allows the CPU to store and retrieve data very quickly. The CPU is attached to two kinds of memory: RAM which is volatile and ROM which is nonvolatile.
