Study Notes
Desktop ICT Components
- Desktop computers are a type of personal computer assembled from various hardware components, each with a specific function.
- These components work together to form a complete system capable of processing information and tasks.
Essential Hardware Components
- Central Processing Unit (CPU): The computer's brain, executing instructions and performing calculations. It determines the computer's processing speed.
- Motherboard: The main circuit board connecting all components, enabling communication and coordinated operation. It houses slots for expansion cards, ports, and the CPU socket.
- Random Access Memory (RAM): Temporary storage for data and instructions used by the CPU. More RAM allows for smoother multitasking.
- Graphics Processing Unit (GPU): Dedicated to graphical processing and display, offloading the CPU for other tasks. More powerful GPUs handle graphics-intensive applications (e.g., gaming, video editing).
- Hard Disk Drive (HDD) or Solid State Drive (SSD): Permanent storage for programs and files. SSDs are faster and more durable than HDDs. Storage capacity is measured in gigabytes (GB) or terabytes (TB).
- Power Supply Unit (PSU): Converts AC to DC power for computer components. Sufficient power is crucial for all components.
- Optical Drives (Optional): CD/DVD drives for reading and writing data on optical discs. Less common now.
- Input Devices: Keyboard, mouse, webcam, microphone, and other peripherals, providing commands and data input.
- Output Devices: Monitor (screen), speakers, printers; displaying processed or generated information to the user.
Peripheral Devices
- Monitor: Visually displays computer-processed information.
- Keyboard: Allows users to input text and commands.
- Mouse: Controls the cursor and enables interaction with screen objects.
- Printers: Create hard copies of documents or images.
- Webcam: Captures video for video conferencing.
- Microphone: Allows audio input.
- Speakers: Output sound.
Software Components
- Operating System (OS): Core software managing hardware (CPU, memory), providing a user interface, and running applications. Examples include Windows, macOS, and Linux.
- Applications: Programs for specific tasks like word processing, web browsing, or photo editing.
ICT (Information and Communication Technology) in Desktop Computers
- ICT encompasses the technologies and processes for managing, sharing, and utilizing information and communication within a desktop setting. This includes networking and data management practices.
Desktop ICT Functions
- Data Processing: Performing calculations, organizing data, and creating reports.
- Communication (limited in a single desktop): Connecting via networks to remote servers or computers. The desktop itself isn't a primary communication hub.
- Data Storage: Maintaining files and data for future access and use.
- Automation: Using software and hardware to automate tasks or processes (e.g., scripts).
- Information Retrieval: Searching and finding relevant information from stored data.
