Study Notes

Information and Communication Technology

  • Information Technology (IT): Refers to hardware and software that enable data access, conversion, storage, organization, manipulation, and presentation.
  • Communication Technology (CT): Involves telecommunications equipment for data access; examples include phones, faxes, scanners, modems, and computers.

Basic Computer Tasks

  • The four essential tasks of any computer: inputting data, processing data, outputting information, and storing data (IPOS cycle).
  • The acronym IPOS emphasizes these sequential functions.

Computer Programs

  • Programs are sets of instructions produced by programmers for creating software.

System Software

  • Operating System (OS): Controls hardware and manages all software. The most commonly used OS is Microsoft Windows.
  • Utility Software: A subset of system software designed to maintain and protect system software, such as antivirus programs, backup systems, and data recovery software.

Application Software

  • Software that performs specific tasks for users, including word processors, spreadsheets, and databases.

Input Devices

  • Manual Input Devices: Require user interaction for input (e.g., keyboards, mice).
  • Direct Data Entry Devices: Automate the transfer of data into a computer (e.g., barcode readers, smart cards).

Barcode Reader

  • Utilizes vertical bars to represent numeric data and is widely used in retail to streamline data entry processes.

Biometric Systems

  • Identify individuals using unique physical traits (e.g., fingerprints, facial recognition) or behavioral traits (e.g., signatures, voice).

Optical Mark Recognition (OMR)

  • Used to input data from marked forms (like lottery tickets) into computer systems, providing quick and accurate data entry.

Optical Character Recognition (OCR)

  • Converts scanned images of printed or handwritten text into editable digital text.

Operating System Functions

  • Booting: The process of starting a computer, involving system checks and loading the OS from disk to RAM.
  • Memory Management: Allocates RAM effectively, using virtual memory when necessary.
  • File Management: Handles saving, organizing, and modifying files.
  • Process Management: Manages CPU time allocation for processes.

Key Hardware Components

  • Central Processing Unit (CPU): The brain of the computer, divided into:
    • Control Unit (CU): Directs instruction execution and data flow.
    • Arithmetic Logic Unit (ALU): Performs calculations and logical operations.

Input Media

  • Keyboards and Keypads: Devices for manual data entry; risk of human error.
  • Mouse: A pointing device that facilitates data input through movement.

Smart Cards

  • Contain a magnetic strip or electronic circuit, allowing data storage and transaction processing without constant database access.

Utility Software

  • Focused on maintaining the health of system software, it supports virus protection, file management, and data recovery.### Input and Output Devices
  • Input devices transfer data to a computer; examples include mouse, keyboard, and scanner.
  • Output devices convey processed data from a computer; examples include printers, computer screens, and speakers.

Memory and Storage

  • Memory allows temporary storage of instructions and data.
  • Storage media include hard disks, CD-ROMs, DVDs, and USB flash drives.
  • Storage devices enable reading and writing of data; hard disk drives, CD-ROM drives, and DVD drives are common.

Peripheral Devices

  • Peripheral devices operate outside the CPU and require it for control.
  • Input, output, and storage devices can all function as peripherals.

Software

  • Software consists of programs dictating hardware functions, essential for the operation of computer hardware.

Touch-sensitive Devices

  • Touchscreens are sensitive to touch and are prevalent in banks, malls, restaurants, and mobile devices like phones and tablets.
  • Touchpads serve as a mouse alternative on laptops, allowing pointer movement through finger gestures.

Pointing Devices

  • Light pens, resembling mice, are hardly used today and are often substituted with touch-sensitive technology.
  • Styluses, with plastic or felt tips, allow precision drawing on graphics tablets and touchscreens, avoiding direct finger contact.

Remote-Control Devices

  • Remote controls transmit data via signals activated by button presses, which are processed by another device upon receiving the signal.

Document Scanners

  • Scanners capture pictures, graphics, and text by scanning from top to bottom, converting them into digital format for printing or emailing.

Microphones

  • Microphones facilitate data entry into computers via voice commands, enabling functions like printing documents and converting speech to text in voice-activated systems.

Digitisers

  • Digitisers convert images and drawings into digital data; digital cameras capture still and video images for later editing.
  • Webcams transmit images over networks, commonly used for online communication or live streaming.
  • Graphics tablets function as digitizers capturing drawings and signatures, facilitating display on monitors and allowing interactive use when overlaid on screens.
