Study Notes
Computer Systems: Hardware and Software
- Hardware: The physical components of a computer system, including input/output devices.
- Internal Hardware: Central Processing Unit (CPU), motherboard, RAM, ROM, graphics card, sound card, hard disk drives (HDD), solid-state drives (SSD), Network Interface Card (NIC).
- External Hardware: Monitor, keyboard, mouse, printer, external storage devices.
- Software: Instructions, commands, and programs that tell the computer what to do.
- Application Software: Performs specific tasks for users (e.g., spreadsheets, databases, word processors).
- System Software: Provides a platform for other software to run (e.g., compilers, linkers, device drivers, utilities, operating systems).
- Compilers: Translate high-level programming languages into machine code.
- Linkers: Connect language processors to create functioning programs, and define data.
- Device Drivers: Enable external devices to communicate with the system.
- Utilities: Provide tools for system maintenance (e.g., antivirus, disk cleanup).
- Operating Systems: Manage the computer's resources, allowing users to interact with it.
Analogue and Digital Data
- Computers process digital data (binary: 0s and 1s).
- Real-world data is usually analogue (smooth curves).
- Analogue-to-Digital Converters (ADCs) convert analogue data into digital form.
- Digital-to-Analogue Converters (DACs) convert digital data back into analogue form.
Main Components of Computer Systems
- Central Processing Unit (CPU): The brain of the computer; understands and executes instructions. Also known as a microprocessor.
- Control Unit (CU): Manages input and output devices.
- Arithmetic and Logic Unit (ALU): Performs calculations and logical operations.
- Registers: Tiny storage areas within the CPU.
-
Internal Memory: Temporary storage for data currently in use.
- RAM (Random Access Memory): Volatile memory lost when power is off.
- ROM (Read-Only Memory): Non-volatile memory, can only be read. Stores configuration data like BIOS setup.
- BIOS (Basic Input/Output System): Stores system configuration data, including date, time, and settings.
- CMOS: Non-volatile chip (often battery-powered) that stores BIOS settings (data).
Input & Output Devices
- Input Devices: Hardware that allows users to enter data (e.g., keyboard, mouse, scanner).
- Output Devices: Hardware that presents the computer's output to the user (e.g., monitor, printer).
Backing and Secondary Storage
-
Backing Storage: Stores large amounts of data permanently.
- Hard disk drives (HDDs): Magnetic storage.
- Solid-state drives (SSDs): Flash memory.
-
Differences between internal memory and backing storage:
- RAM loses data when power is off, ROM is read-only, and backing storage is permanent.
- Internal memories are faster and smaller than backing storage.
- Backing storage is usually less expensive.
Operating Systems
-
Operating Systems (OS): Manage computer hardware and software resources.
- Control input, output, and secondary storage.
- Load, run, and store application programs.
- Handle errors in applications.
- Maintain system security and logs.
-
User Interfaces: How users interact with the computer.
- Command Line Interface (CLI): Users type commands.
- Graphical User Interface (GUI): Uses windows, icons, menus, and pointing devices.
- Dialogue-based User Interface: Uses voice input.
- Gesture-based User Interface: Uses hand, head, or foot movements.
Types of Computers
-
Desktop Computers: Separate monitor, keyboard, mouse, and processor unit.
- Advantages: Upgradable, standardized parts, good specifications for price.
- Disadvantages: Not portable, complex to set up, not mobile.
-
Mobile Computers:
-
Laptops: Integrated monitor, keyboard, pointing device, and processor unit.
- Advantages: Portable, wireless connections.
- Disadvantages: Battery limitations, smaller keyboards/screens.
-
Smartphones: Cell phones with OS, apps, internet connectivity.
- Advantages: Portability, instant apps and location services.
- Disadvantages: Small screens, slower typing compared to laptops.
-
Tablets: Large, flat handheld computers.
- Advantages: Portability, touch screen, faster boot times, long battery life.
- Disadvantages: Smaller storage, expensive compared to laptops.
- Phablets: Hybrid smartphone/tablet.
-
Laptops: Integrated monitor, keyboard, pointing device, and processor unit.
Impact of Emerging Technologies
- Artificial Intelligence (AI): Machines that perform tasks requiring intelligence. (e.g., self-driving cars, robotic research for disabilities).
-
Extended Reality (XR): Combined real and virtual environments:
- Augmented Reality (AR): Overlays virtual objects onto the real world (e.g., Pokemon Go).
- Virtual Reality (VR): Creates totally virtual environments (e.g., gaming, simulations).
