Study Notes
Main Components of Computer Systems
- Computer systems comprise hardware (physical parts) and software (intangible programs).
Hardware
- Input Devices: Allow users to enter data (e.g., keyboard, mouse).
- Output Devices: Display or present data (e.g., monitor, printer, speaker).
Central Processing Unit (CPU)
- Acts as the "brain" of the computer, executing instructions and managing resources.
Graphics Processing Unit (GPU)
- Specialized for rapid image and video data processing; ideal for parallel tasks like 3D rendering.
CPU vs. GPU
- CPU: General-purpose, aligns with sequential processing; handles diverse applications but less efficient for parallel tasks.
- GPU: Excels at tasks suited for parallel processing; great for graphics and machine learning but primarily designed for graphics-related functions.
Advantages and Disadvantages
- CPU Advantages: Versatile, can perform a wide range of tasks.
- CPU Disadvantages: Less efficient in parallel processing; may consume more power.
- GPU Advantages: Highly efficient for parallel tasks and energy-efficient in specific workloads.
- GPU Disadvantages: Generally costly and programming complexity increases when utilizing GPUs.
Motherboard
- The main circuit board connecting all computer components.
Primary Storage Devices
- RAM (Random Access Memory): Temporary storage for data and instructions.
- ROM (Read-Only Memory): Permanent storage for critical system software.
Secondary Storage Devices
- HDD (Hard Disk Drive): Magnetic data storage.
- SSD (Solid-State Drive): Fast, reliable flash memory storage.
- M.2 SSD: Compact SSD form factor, commonly in laptops.
- Floppy Disk: Obsolete medium for removable data storage.
- Optical Drive: Reads/writes data to CDs/DVDs/Blu-ray.
- Flash Drive: Portable storage for data transfer and access.
Power Supply Unit (PSU)
- Converts AC power to DC power for computer components.
Cooling System
- Maintains optimal operating temperature using fans and heat sinks; thermal paste is utilized for improved heat transfer.
Networking Devices
- Include Network Interface Card (NIC), Wireless Card, and Wi-Fi Stick for connectivity.
Input/Output Ports
- USB Ports: Connect various devices.
- HDMI Ports: High-quality video and audio output.
- DisplayPort: Digital video interface for display connections.
- VGA: Older analog video interface for display connections.
- Ethernet: Establishes connections to wired networks.
- Audio Ports: Color-coded ports for microphones, speakers, and headphones.
Internal Ports
- PCI: Expansion slot for connecting devices like network and sound cards.
- PCIe: High-speed expansion slot for performance devices like GPUs and SSDs.
- SATA: Connects storage devices (HDDs and SSDs).
- PS/2: Older port for keyboards and mice.
- CMOS Battery: Powers CMOS memory for BIOS settings.
Software
- Divided into two categories:
- System Software: Manages basic computer operations (e.g., operating systems like Windows, macOS).
- Application Software: Designed for specific user tasks (e.g., word processors, games).
System Software Examples
- BIOS (Basic Input/Output System): Firmware stored on the motherboard chip, crucial for system startup and management.
