Study Notes
Computer Storage Interfaces
- Integrated Drive Electronics (IDE) and Serial ATA (SATA) are essential standard interfaces for PC-compatible computers.
- IDE was developed in 1986 by Western Digital and Compaq, designed for hard drives and CD/DVD drives.
- SATA succeeded the older Parallel ATA standard and is now the primary interface for storage devices.
Hard Disk Drive (HDD)
- An HDD is an electro-mechanical storage device that uses magnetic storage to store and retrieve digital data.
- Contains one or more rigid platters coated with magnetic material that rotate rapidly.
Central Processing Unit (CPU)
- The CPU, also known as the processor, is the primary electronic circuitry in a computer responsible for executing program instructions.
- Performs essential functions: arithmetic, logic, control, and I/O operations.
Power Supply Unit
- Converts mains AC voltage to low-voltage regulated DC power for computer components.
- Modern PCs typically utilize switched-mode power supplies for efficiency.
System Unit
- The system unit houses critical components such as the motherboard, CPU, and RAM, and performs core computing functions.
Input and Output Devices
- Output Devices: Convert data into a human-perceptible format (e.g., monitors, printers).
- Input Devices: Enable user interaction with the computer (e.g., keyboards, mice).
Light Pen
- A light pen is an input device enabling drawing on a CRT display, providing high positional accuracy and functionality akin to a touchscreen.
Image Scanner
- Scanners optically convert images or printed materials into digital formats, commonly utilizing flatbed versions for document scanning.
Microphone
- A mic converts sound into electrical signals, essential for audio input in computing environments.
Printers
- Printers produce physical representations of graphics or text, primarily on paper, and encompass various types like inkjet and laser.
Computer Monitors
- Monitors serve as output devices displaying visual information, including text and graphics, typically featuring a screen and internal circuitry.
Video Card and Sound Card
- A video card enhances a computer's display capabilities, while a sound card improves audio output through speakers.
Input/Output (I/O) Devices
- Common Input Devices: Graphics tablets, joysticks, webcams.
- Common Output Devices: Monitors, printers, plotters.
- Combined I/O Devices: Headsets (combining microphones and speakers), touch screens.
Computer Software
- Software is a collection of programs and documentation essential for computer operations, divided into system and application software.
- System Software: Manages hardware and provides a platform for running application software, including operating systems like Windows, Linux, and mobile systems like Android.
BIOS and Firmware
- BIOS is a core program stored in EPROM that initializes hardware when the computer is powered on.
- Firmware includes permanent software instructions for hardware functionalities.
Shell
- The shell acts as an interface between the user and the operating system, facilitating interaction to control devices and run applications (e.g., command lines in MS DOS or terminal in Ubuntu).
