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.
- Types:
-
Secondary Memory: Used for persistent data storage.
