Study Notes

Major Computer Operations

Five key computer functions: accepts data (input), stores data, processes data, provides results (output), and controls operations.

Information Technology (IT)

Information Technology, essential in the Information Age, influences daily life and work environments.
Definition: IT encompasses technologies used to create, collect, process, protect, and store information, including hardware, software, and computer networks.

Concepts Under Information Technology

Computer

Origin: The term "computer" derives from the Latin "computare," meaning to calculate or think together.
Definition: An electronic device that processes user input, executes instructions, and produces output.

Architecture of Computer

Computer architecture specifies the interaction of software and hardware standards to form a computer system.
Refers to how computer systems are designed and operated.

Components of a Computer System

Central Processing Unit (CPU): The core of the computer that processes instructions.
- Control Unit (CU): Directs operations within the computer.
- Arithmetic and Logical Unit (ALU): Performs calculations and logical comparisons.
Memory Units:
- Primary Memory: Holds active data and instructions during processing.
  - Types:
    - RAM (Random Access Memory): Temporary, read/write memory, commonly referred to as main memory.
    - ROM (Read-Only Memory): Permanent memory that stores essential instructions.
- Secondary Memory: Used for persistent data storage.

Data vs. Information

Data: Raw facts and figures (e.g., Umbar, 1234, MG Road).
Information: Processed data that is organized and formatted for usefulness (e.g., contact details of an individual).

Need for Information

Information is crucial for making short-term and long-term decisions, as well as strategic planning within organizations.

Data Processing Capabilities

Computers can process diverse formats, including data, images, audio, video, and graphics, making them versatile for various tasks.
