Computer
The computer is an electronic device that is capable of receiving information or data and performing a series of operations in accordance with a set of operations. This produces results in the form of data or information. A computer is a machine capable of solving problems and manipulating data. It accepts and processes the data by doing some mathematical and logical operations and gives us the desired output.
in other language Computer is an electronic machine which has been mastered in rapid calculation, today the use of computers is increasing in all fields, now the computer is not only used for addition and remainder, it is now a machine used even in rocket science. It is really such an amazing machine that processes our given Instructions (Input) and produces useful Results (output|).
Computer Hardware: It is the external part of the whole computer that we can see even by touching or in other language say that the parts and devices of the computer which we can touch and see are hardware. It is physically connected to the computer.
Computer Software: It is a set of instructions and programs. A computer needs a set of programs to program and run it, these are called software, which gives the ability to any user to work on the computer very easily.
Computer User: The one who operates the computer is the user because the computer needs to be operated and turned on at least once, to run any software, the user’s instruction is required.
Computer Data: Any type of instructions and programs in the computer are kept in the form of numbers which can be read and stored.
Computer 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 an organized way and processes them one after the other in the computer.
Computer Storage: To save the data and store it safely, 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
- Intermediate results of processing are also stored here.
Computer Processing: Some operations are required to perform any task, these operations are arithmetic and logical operations, these operations are called processing. CPU processes the data and instructions from the storage unit and according to the instructions given, the data is provided to us, which is then sent back to the storage unit.
Computer Output: When we give any kind of instruction or input to the computer, it processes them and generates a result and output. All this output is stored in the storage unit before it is shown to us and is visible to us in a human-readable form.
Computer Control: Controlling of all operations like input, processing, and output are performed by the control unit. It takes care of the step-by-step processing of all operations inside the computer.
