Study Notes
Major Characteristics of Computers
- Computers exhibit high speed, accuracy, diligence, versatility, and significant storage capacity.
Computer Organization
- Basic structure includes Input Unit, Memory Unit, Control Unit, Arithmetic Logic Unit (ALU), and Output Unit.
- These units collaboratively perform five main operations:
- Accepting input
- Storing data
- Processing data
- Producing output
- Controlling internal operations
Key Components of Computer Operations
- Input: Entry of data and instructions into the system.
- Control Unit (CU): Manages and supervises all operations and processes input and output.
- Memory Unit: Stores data and instructions temporarily for processing.
- Arithmetic Logic Unit (ALU): Executes mathematical operations (addition, subtraction, multiplication, division) and logical operations (comparisons).
- Output: Displays results and information derived from processed data.
Central Processing Unit (CPU)
- Comprised of ALU and CU, often referred to as the brain of the computer.
Peripheral Devices
- Connect externally to the computer and serve specific functions, categorized into:
- Input Devices
- Output Devices
- Other Peripherals
Input Devices
- Accept data and instructions from users; examples include:
- Keyboard
- Mouse
- Light Pen
- Optical/Magnetic Scanner
- Touch Screen
- Microphone
Scanners
- Scanners convert physical documents into digital formats.
- Bar-code readers are specialized image scanners for automatic data collection.
- Optical Character Recognition (OCR) devices convert scanned pages into editable text.
Touch Screens
- Allow input through direct touch on the screen, providing an alternative to conventional keyboards.
Microphone
- Captures voice inputs; two types include Desktop Microphone and LCD Microphone.
Monitor Types
- Cathode Ray Tube (CRT): Traditional bulky monitors resembling televisions.
- Liquid Crystal Display (LCD): Slim, flat-panel monitors preferred for their modern aesthetics and lower power consumption; resolution often at least 800 x 600 pixels, with high-end models reaching 1024 x 768 or 1280 x 1024 pixels.
Printers
- Produce hard copies of documents; different types include:
- Laser Printer: High speed and quality, silent operation.
- Inkjet Printer
- Dot Matrix Printer
- Line Printer
Software
- Utility Programs: Software for specific functions (e.g., file management, antivirus protection).
- Application Software: Programs designed for specific tasks. Examples include:
- Library Information System for managing book and user details.
- Student Information System for handling student records and examination processing.
Types of Application Software
- Generalized Packages: Designed for common tasks such as document creation, presentations, and gaming.
- Customized Packages: Tailored software for specialized needs or functions.
