Study Notes
Functions of Computer Components
- The Input Unit allows users to enter data and commands into the computer, translating human actions into a format the computer can process.
Brain of the Computer
- The Central Processing Unit (CPU) is referred to as the brain of the computer system, responsible for executing instructions and processing data.
Memory Unit Function
- The Memory Unit stores data and instructions temporarily or permanently, enabling quick access for the CPU during computing tasks.
Role of the Central Processing Unit (CPU)
- The CPU carries out arithmetic, logic, control, and input/output (I/O) operations specified by the instructions in the program, managing the flow of data within the system.
Data Translation Device
- Input devices, such as keyboards or scanners, translate data from a human-understandable format into electronic impulses that the computer can interpret.
