Study Notes
Introduction to Computers and ICT
- ICT encompasses technologies like the internet, cell phones, and digital platforms, enabling information access through telecommunications.
- Proficiency in ICT is essential for academic, professional, and social success.
- Examples of modern ICT applications include fitness trackers, home automation, and self-driving cars.
What is a Computer?
- A computer is an electronic device capable of inputting data, processing instructions, outputting results, and storing data.
- Its core functions are input, processing, output, storage, and communication.
- Computers are versatile tools due to their ability to perform tasks ranging from simple calculations to complex problem-solving.
Computer System Components
- Hardware encompasses the physical components of a computer, including the CPU, monitor, keyboard, and storage devices.
- Software provides instructions for hardware operation and includes operating systems and application software.
- Software interacts with hardware to execute user commands.
Basic Computer Structure
- Computer architecture comprises units that enable data processing, interpretation, and output.
- These units include the input unit, central processing unit (CPU), and output unit.
- The CPU consists of the arithmetic logic unit (ALU) for calculations and the control unit (CU) for managing instruction execution.
- Registers within the CPU hold data temporarily during processing.
Input Devices
- Input devices enable users to enter data and instructions into the computer.
- Examples include keyboards for text input, mice for navigation, microphones and webcams for audio and video capture, and scanners for converting visual information into digital data.
Output Devices
- Output devices convert and display processed data to users.
- Examples include monitors for visual output, printers for hard copies, speakers and headphones for audio output, and specialized devices like Braille readers for visually impaired users.
Storage units in Computers
- Storage units are essential for storing and retrieving data long-term.
- Primary storage includes RAM (Random Access Memory) for temporary storage of active tasks and cache for high-speed data access.
- Secondary storage encompasses hard disks, SSDs, and optical media for permanent data storage.
