COMPUTER DATA CONVERSION

Data conversion is the conversion of computer data from one format to another. Throughout a computer environment, data is encoded in a variety of ways. For example, computer hardware is built on the basis of certain standards, which requires that data contains, for example, parity bit checks.

Similarly, the operating system is predicated on certain standards for data and file handling. Furthermore, each computer program handles data in a different manner. Whenever anyone of these variables is changed, data must be converted in some way before it can be used by a different computer, operating system or program.

REGISTERS:

A register is a small, high-speed storage location within the CPU that temporarily holds data, instructions, or addresses during processing.

TYPES OF REGISTERS IN THE CPU

​MDR (Memory Data Register):

Holds data that is being transferred to or from memory. It acts as a buffer between the CPU and memory during data access.

Stores the current instruction being executed by the CPU, allowing the processor to decode and process the instruction

​

​CIR (Current Instruction Register)

Keeps track of the sequence and status of instructions, often used to manage the flow of operations within the CPU.

​

​SQR (Status or Sequence Register):

Address

An address is a unique identifier used to locate a specific storage location in the memory where data or instructions are stored

​BUS

A bus is a communication pathway that transfers data and instructions between the CPU, memory, and other components of a computer.

Functions of register
The three important functions of computer registers are fetching, decoding, and execution. Data instructions from the user are collected and stored in the specific location by the register. The instructions are interpreted and processed so that the desired output is given to the user.

Conclusion

Registers play a crucial role in data processing by temporarily holding data, instructions, and addresses, enabling fast and efficient data conversion and execution in the CPU.
