COAL Flashcards
All of the electronic and mechanical equipment in a computer is called the hardware.
HARDWARE
example of hardwares
- Motherboard
- Hard disk
- RAM

is used to describe computer
programs that perform a task or tasks on a computer
system.
software
Software can be grouped as
- System software - Operating System etc.
- Utility programs - Antivirus etc.
- Applications Software - Word, SolidWorks etc.
collection of electronic and
mechanical devices operating as a unit.
computer system
The main parts of computer system
- System unit
- Monitor
