Data: Any type of instructions and programs placed in the computer in the form of numbers which can be read and stored.

Input: In order to process the computer or operate any software, we need to give input to the computer, it takes the input data in a systematic way and processes one after the other in the computer.

Storage: To save and store data securely, a storage unit is required where the data is stored permanently. The storage unit performs the following major functions:

  • All data and instructions before and after processing are stored here, and
  • The intermediate results of processing are also stored here.

Processing: Some operations are required to perform any task, these operations are arithmetic and logical operations, these operations are called processing. The CPU processes the data and instructions from the storage unit and as per the given instructions, the data is provided to us, which is then sent back to the storage unit.

Output: When we give any kind of instructions or inputs to the computer, it processes them and produces results and outputs. All this output is stored in the storage unit before being shown to us and visible to us in human-readable form.

Control: They are fixed even after typing, as they are typed and they also have a result. This last is important.
