3.1 Hardware

external image 800px-Computer_icon.png
The hardware topic deals with a computer system consisting of input devices, output devices, a central processing unit and storage. ITGS students are required to understand the meaning of the terms and concepts listed here and, where appropriate, briefly describe how they work.

The increasing tendency to develop hardware in modular units raises a range of social impacts and ethical issues such as the use of non-renewable natural resources, the global transportation of manufactured components and their eventual disposal by individuals, organizations and governments. Students are expected to discuss possible solutions and evaluate their effectiveness.

Possible scenarios to address:
A computer user is planning to upgrade their current computer system to a newer model and must use their knowledge to
  • understand the specifications of the proposed new system
  • evaluate other physical considerations that may influence the choice of the physical environment of the proposed new system, such as ergonomics and other health-related issues
  • suggest upgrades to the computer system to take advantage of improvements in components, such as processing speed
  • describe how the proper disposal of the old computer system can take place and whether the choice
  • of computer may be affected by the manufacturer’s policies on disposal

The computer system key terms:
  • Types of computers: personal digital assistant (PDA), laptop, desktop computer
  • MAC address
  • Motherboard
  • Central processing unit (CPU), microprocessor, clock speed: for example, megahertz (MHz), gigahertz
  • (GHz), terahertz (THz)
  • Primary storage: read-only memory (ROM), random-access memory (RAM)
  • Secondary storage: optical, magnetic, flash memory: for example, USB (universal serial bus) flash drive
  • Bit, byte, kilobyte (KB), megabyte (MB), gigabyte (GB), terabyte (TB), petabyte (PB), exabyte (EB), zettabyte (ZB), yottabyte (YB)
  • Character encoding: ASCII (Unicode and American Standard Code for Information Interchange)
  • Ports

Input and output devices key terms:
  • Keyboards, mice, touch pads
  • Optical mark recognition (OMR), optical character recognition (OCR), magnetic ink character
  • recognition (MICR), radio frequency identification (RFID), radio tag, bar code scanners, magnetic stripe readers
  • Microphones
  • Smart card readers
  • Webcams, digital cameras, digital video cameras
  • Sensors, probes, real-time data collection
  • Composite devices: for example, game controllers
  • Touch-sensitive devices: for example, pads
  • Printers, monitors, speakers, projectors
  • CD-ROM (compact disc read-only memory), DVD (digital versatile/video disk) readers and burners
