Homework

Read pages 14-21 (blue book) and add any terms that you do not know to your definitions list.

Read Chapter 1 Gray - Introduction pages 2-9 and page 39

Look at the back of your home computer and try to identify the different connections and ports.
Prepare for the Ports Quiz - Friday. Know the ports found on a typical computer. This page may help you review - scroll down to the picture of the back of a computer and see if you can name each port.

Continue searching for your first news article, this will be due this Friday. Place your summary and news article information in your Excel file or create a Google Docs spreadsheet. The focus for this weeks news article are the stakeholders. Who are they and why do they have an interest in this topic? Post to school loop.

What

3.1 Hardware - pages 26-27
Introduction
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 scenario
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.

IT concepts to address in this topic
The computer system
• 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
• 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

Why

Computers are the basis of IT systems and an understading of computers is the foundation of this course.

How

Class discussion of computer systems, homework questions and the laptop lab.
