Software
There are software which tell hardware how to interact with the computer system as a whole. These are called
Device Drivers
There are software which maintain the computer system such as configuration, monitoring and security. These are called
Utility Software
There are software which manage the computer system’s resources and services for other software. These are called
System Software
It manages the computer system and
provides an environment where apps can communicate with the user.
Operating System
a circuit that carries out instructions for the computer system. Also known as processor
CPU
stores data and instructions for the operations of the CPU.
Memory Unit
High-speed, volatile memory. Volatile means that the information which is stored will be erased when the computer system shuts down
Random Access Memory
Slower, non-volatile memory. Non-volatile means that the information is stored and not erased even when the computer system shuts down.
Read-only Memory
It is not directly accessed by
the CPU
Secondary Memory
