Basic Operations of Computer
The computer is an electronic device that receives input from the user, stores and processes the instruction as per user instructions, and provides output in the desired format.
Data
The computer input is called Data. Data is raw facts and figures which have no much significance can be processed using arithmetic and logical operation to obtain meaningful information. Data is represented with characters such as alphabets (A-Z, a-z), digits (0-9), or special characters (+,-,/,*,<,>,=, etc.)
Information
The output obtained after processing the data based on the user's instruction is called information. Information is organized or classified data, which has some meaningful values.
Basic operations of the computer system
Five basic operations for converting raw input data into information are as follows:
Inputting:
Inputting is a basic operation of a computer system. Inputting is the process of entering the data and instruction into the computer. A device that enters data into a computer, such as a keyboard or a mouse, is called an input device.
Storing
Storing is the process where all input data, instructions, and the intermediate results produced by the computer are stored in the memory. Memory is of two types – primary memory and secondary memory. Primary memory resides within the CPU whereas secondary memory is external to it.
Processing
The task of performing calculations and comparisons are known as processing. ALU (Arithmetic and Logical Unit) unit is responsible for processing in Computer System. ALU is the place where the actual execution of the instructions takes place during the processing operations.
Outputting
Outputting is the process of providing information to the user in the desired format. A device that provides information to the user such as a monitor, or a Printer, is called an output device.
