Study Notes
Introduction to Computer Basics
- Overview of computer system design and organization of components.
- Components divided into two categories: hardware (physical devices) and software (programs).
- Importance of systematic instruction feeding for task performance.
Objectives of the Lesson
- Understand basic organization of a computer system.
- Identify and explain types of input and output devices.
- Define software and its classifications.
- Differentiate between system software and application software.
- Describe computer languages and their classifications.
What is a Computer?
- A computer transforms data into meaningful information.
- Data examples: marks, personal information (name, age, etc.).
- Functions of a computer include:
- Accepting data.
- Storing data.
- Processing data.
- Retrieving stored data.
- Producing outputs in desired formats.
- Major characteristics: high speed, accuracy, diligence, versatility, and storage capacity.
Computer Organization
- Basic operations of a computer represented in a block diagram.
- Five major functions of computers:
- Input: Entering data and programs into the system.
- Control Unit (CU): Supervises input, output, processing, and storage; manages data flow.
- Memory Unit: Stores data and instructions.
- Arithmetic Logic Unit (ALU): Performs calculations (addition, subtraction, multiplication, division) and logical operations (comparison).
- Output: Producing results from data to generate useful information.
Central Processing Unit (CPU)
- Composed of the ALU and CU; often referred to as the brain of the computer system.
Intext Questions Overview
- Basic operations performed by computers include input, storage, processing, output, and control.
- Definitions:
- ALU: Arithmetic Logic Unit, performs arithmetic and logical operations.
- CU: Control Unit, supervises all operations.
- CPU: Central Processing Unit, consists of ALU and CU.
Peripheral Devices
- Definition: External devices connected to the computer.
