Input devices sends data to the central processing unit. Central processing unit (CPU) excutes computer instructions. Memory holds data and programs currently in use. In the same time secondary storage devices stores data and programs. Lastly output devices make processed data (information) available.
The main devices that do the most work at computing in all computers it the CPU (Central Processing Unit) and GPU (Graphics Processing Unit).
Information consists of the processing results produced by a computer. By definition, computers are devices that convert raw data into useful information.
the processing devices are CPU, CD-ROM, and Memory Card
Processing devices are those devices which are used for processing the computer system. For example:mother board, video card,sound card etc.
Information processing involves five phases: input, process, output, storage, and retrieval. Each of these phases and the devices associated with each are discussed below.
Input devices are used to capture data at the earliest possible point in the workflow, so that the data are accurate and readily available for processing.

Input some raw data after processing you will get Information as Output. The structure will be like this..........
