Study Notes
Introduction to ICT
- ICT stands for Information and Communication Technology, which facilitates information transfer and various electronically mediated communication methods.
- The ICT Development Index (IDI) quantitatively measures ICT access, usage, and skills across different regions and countries.
Key Definitions
- Information: Knowledge gained through reading, investigation, study, or research.
- Communication: Exchanging information between individuals using verbal and non-verbal methods.
- Technology: Methods, systems, and devices derived from scientific knowledge for practical use.
Computer Systems
- A computer system consists of interconnected computers that share a central storage system and peripheral devices.
Architecture Components
- Hardware: Physical equipment that processes data by executing instructions and provides input/output capabilities.
- Software: Programs that perform tasks and execute instructions within the system.
- Data: Basic representation of facts and observations.
- Communications: Facilitates data sharing and processing among various systems.
Components of a Computer
- Hardware: All physical components of a computer system.
- Software: Electronic instructions that guide the computer in task execution, developed through programming.
Software Classifications
- System Software: Manages hardware and allows application programs to operate; coordinates activities of computer components.
- Application Software: Designed for end-users to perform specific tasks; can be standalone or a suite of programs.
Hardware Classifications
- Input Devices: Hardware that connects to a computer for user input (e.g., keyboard, mouse).
- Output Devices: Hardware converting information into perceivable formats for humans (e.g., LED, CRT, LCD).
- System Unit: Enclosure containing main components like CPU, memory chips, motherboard, power supply, and secondary storage.
Inside the System Unit
- Houses the following essential components:
- CPU (Central Processing Unit): Executes instructions and processes data.
- Motherboard: Main circuit board housing CPU and other components.
- Memory Chips: Temporary storage for data being processed.
Types of Computers
- Various classifications exist depending on size, capability, and technology used, although specifics are not detailed in the provided text.
