Study Notes

Purpose of Computer in Data Processing

The core function of a computer is to process data, taking raw input, manipulating it, and producing meaningful output.

Unit of Speed in Computers

The gigahertz (GHz) is used to measure the speed of a computer's central processing unit (CPU). A higher GHz rating indicates the CPU can process instructions faster.

Advantages of Computers for Calculations

Computers excel at calculations due to their speed, accuracy and ability to handle complex algorithms.

Function of the Computer in Controlling Operations

The Central Processing Unit (CPU) is responsible for controlling and coordinating all the input, processing, and output operations of a computer system.

Purpose of Data Storage in a Computer's Memory

The main purpose of storing data and instructions in a computer's memory is to enable rapid access and processing by the CPU. This allows for quick retrieval of information during calculations and execution of programs.
