Central processing unit (CPU Central Processing Unit:) Display unit (unit output): monitor, printer.2. the software. Software or computer program is an important element, which is the second step of the sequence will be ordered to work hardware. To process the data results based on usage. At present, the operating system software, software, control systems, software and application software for various styles of previous software. The user must contact using primarily text.
