Study Notes
Chapter 1: Introduction to ICT
- ICT stands for Information Communication and Technology; it encompasses methods, systems, and devices enabled by scientific knowledge for practical use.
- Information represents meaningful data, processed by various technologies for communication such as radio, TV, and newspapers.
- ICT allows for global communication at any time by anyone, enabling digitization, storage, processing, transmission, and retrieval of digital data.
- Digitization involves converting text, images, or audio into a format manageable by computers.
- Key components of ICT include information systems for various sectors:
- E-government services facilitate citizens' access to government information.
- Education services utilize web-based platforms for learning materials and online courses, supported by Learning Management Systems.
- The health sector employs advanced machinery like CAT and MRI machines for diagnostics, and telemedicine for remote healthcare.
- Agriculture benefits from ICT devices like automated insect control and weather monitoring systems.
- Industries leverage automation, e-banking, and online shopping platforms.
- Transport utilizes ICT for traffic monitoring and intelligent systems.
- Drawbacks of ICT include addiction to gaming, physical ailments, negative social interactions, and mental health issues.
Chapter 2: Introduction to Computer
- A computer is an electronic device that processes data, stores it, and generates user-output; it consists of hardware and software.
- Hardware refers to the physical components, while software consists of instructions that direct the hardware.
- Characteristics of computers include speed, reliability, accuracy, and storage capacity, but they lack intelligence and emotions.
- Computer classifications include:
- Supercomputers for intensive computations.
- Mainframe computers for large data processing.
- Minicomputers for laboratory uses.
- Microcomputers for everyday tasks.
- Historic generations of computers:
- First Generation (1940-1956): Utilized vacuum tubes, large size, and high power consumption.
- Second Generation (1956-1963): Used transistors, smaller size, and more efficient power usage.
- Third Generation (1964-1975): Features integrated circuits and the birth of operating systems.
- Fourth Generation (1975-1989): Introduced microprocessors and personal computers with graphics user interfaces.
- Fifth Generation (1989-present): Focus on artificial intelligence and advanced processing capabilities.
Parts of Computers
- Hardware components include:
- CPU (Central Processing Unit): Executes programs, measured in MHz.
- ALU (Arithmetic Logic Unit): Performs arithmetic and logical operations.
- Memory: Divided into volatile (temporary) and non-volatile (permanent).
- Input devices enable instructions and data entry, including keyboards, mice, scanners, and microphones.
- Output devices produce data output in various forms:
- Display devices (CRT, LCD, LED), printers (impact and non-impact), and speakers.
- The motherboard and computer ports define connectivity and communication:
- Types of ports include Parallel, Serial, PS/2, USB, and SCSI, each serving different peripheral connections and data transmission speeds.
- Processor manufacturers include Apple, Intel, and AMD; processor types range from single-core to multi-core architectures.
