components of computer for processing data
Answers
Input devices are hardware devices which take information from the user of the computer system, convert it into electrical signals and transmit it to the processor. The primary function of input devices is to allow humans to interact with the computer system. For instance a mouse allows the user to control the movement of the pointer (a common element in user interface design).
Output devices take data from the computer system and convert it to a form that can be read by humans. For instance a monitor creates a visual electronic display to output information created by the processor to the user.
Processing devices are the components responsible for the processing of information within the computer system. This includes devices such as the CPU, memory and motherboard.
Storage devices are components which allow data to be stored within a computer system. This includes devices such as hard disk drives and compact disk drives.
✔A computer has four main components: the central processing unit or CPU, the primary memory, input units and output units.
✔ A system bus connects all four components, passing and relaying information among them. This type of computer organization and architecture is called a "von Neumann machine" after John von Neumann, who finalized the theory and design of the first modern digital computer.
