  1. 1. 1 ELCL605 Heejung An Week 2
  2. 2. 2 What to do: Discussion Question for weeks 1-2
  3. 3. 3 Computer Basics Hardware
  4. 4. 4 Hardware Hardware includes all of the computer components and devices that are physical pieces or equipment, like the computer machine itself, the monitor, keyboard, printer, mouse, and speakers.
  5. 5. 5 Hardware Hardware consists of five main components.  Central Processing Unit (CPU).  Memory: This is very fast temporary storage used to hold data.  Input devices: Mouse, Keyboard, Microphone, etc.  Output devices: Printer, Speakers, Monitor, etc.  Storage: Hard-drive, Floppy drive, Jump drive, CD-ROM Drive, DVD Drive.
  6. 6. 6 Hardware: CPU Central Processing Unit (CPU) or Microprocessor chip: the brain of the computer.  Fast processor = better = fast response time. (800 MHz is faster than 400 MHz)  Speed is measured in MHz (megahertz). (e.g., Intel Pentium 4 processor chip) http://www.intel.com/
  7. 7. 7 Hardware: Memory ROM (Read only memory) for booting up. RAM (Random Access Memory):  Acts as the “workspace” – The bigger the space, the more work the CPU can get done at any point in time. RAM is where data is stored while being used and processed.  Measured in mega bytes (MB) or GB (gigabytes).  Some programs require lots of RAM (e.g., Photoshop), and the computer will run very slow if you don’t have much RAM.  Remember- More RAM is better. 128 MB is better than 64 MB.
  8. 8. 8 Determining your computer’s CPU & RAM Start > Control Panel > System Processor type Amount of RAM
  9. 9. 9 Hardware: Input Devices Pieces of hardware that allow you to enter data into the computer.  e.g.) Keyboard, Mouse, Stylus, Microphone, Scanner, Digital Camera, etc.
  10. 10. 10 Scanner Allows you to capture and then translate printed copies or images into digital data.
  11. 11. 11 Hardware: Output Devices Pieces of hardware that move information off of the computer :  e.g.) Monitor (soft copy) Printer (hard copy) Speaker, SmartBoard, Projector
  12. 12. 12 Monitor The screen size refers to the number of inches measured across the screen. e.g.) 15’’, 17’’, 24’’ …. Resolution refers to the clarity and crispness of the images on the monitor screen.. diagonally
  13. 13. 13 What is Smart Board? It is an interactive whiteboard that is connected to a computer and a data projector. Once the computer image is projected on the board, the Smart Board can be used as a computer. By just using your finger you can control the computer.
  14. 14. 14 Hardware: Storage - Hard (Disk) Drive Where all of the programs (including the operating system and applications) are stored. And, where you save your personal files.  Usually C: on PCs.  Readable / writable  Size measured in gigabytes (GB).  Bigger hard drive (more GB) is better (more space to store/save programs and your files)
  15. 15. 15 Hard Drive Status - Windows PC Start > My computer > Right click on the C drive (C:) > Properties
  16. 16. 16 Hardware: Removable Storage Devices DVD-ROM (digital versatile discs): 4.7 GB CD-ROMs (compact-disc-read- only memory): 650 MB CD-Rs (recordable) CD-RWs (rewritable) Floppy disk: 1.44 MB Zip disk: 100, 250, and 750 MB USB Flash Drive (called jump drives or keychain drives): 128 MB to 2 GB
  17. 17. 17 Accessing Drives: Windows PC “My Computer” will indicate all of the drives that are currently connected to your computer. Hard Drive- C: Removable drive - E: (if you have two CD- ROM drives, it might be F:) CD-ROM drive - D: Floppy drive - A:
  18. 18. 18 Accessing Drives: Windows PC Hard Drive C: CD-ROM Drive D: Floppy Drive A: Removable Drive E or F:
  19. 19. 19 Display Properties in Windows Right click in an empty space on the desktop > Select Properties > Click on the Settings tab. Also, you can change the background, etc.
  20. 20. 20 Other emerging digital technologies Handheld Computers: Known as PDAs (Personal Digital Assistant):  http://www.citejournal.org/vol7/iss1/scienc e/article1.cfm  http://www.biokids.umich.edu/about/  http://education.mit.edu/pda/overview.htm
  21. 21. 21 Computer Basics Software
  22. 22. 22 Software Software: the name given to the programs that you install on the computer to perform certain types of activities. Software Operating System Software Application Software (Application Program)
  23. 23. 23 Operating System (OS) • creates an interface between the user and computer (GUI – Graphic User Interface). • provides a software platform on top of which other programs, called application programs, can run. • tells the computer how to function and how to manage its own operations. e.g.) - Mac OS X for Apple Macintosh, - Windows and Linux OS for a PC, - The Palm OS for Palm Pilots.
  24. 24. 24 Operating System (OS) controls the computer by: • managing the settings of the display, network connections, time/date, other devices connected to the computer, etc. • installing and running other programs such as games, word processing, browsers, etc. • managing file space on the hard drive and other removable drives that are connected to the computer. • managing user accounts (if more than one), logins, , etc.
  25. 25. 25 Application Software (or Application Programs): A set of instructions that tells the computer how to complete a unique task. e.g.) - Microsoft Word, PowerPoint, Excel. - Adobe Photoshop. - Macromedia Dreamweaver, Flash.
  26. 26. 26 Word Processor A word processor is an application that is used to produce easy to read, professional-looking documents:  e.g., Microsoft Word, Microsoft Works, Corel WordPerfect, etc.
  27. 27. 27 Presentation Software Includes programs that are designed for creating digital support materials for presentations. e.g.) - Microsoft PowerPoint - Apple Keynote
  28. 28. 28 Lab…continued Technical aspects:  Use a master slide  Use animation effects somewhere in the presentation  Slide transitions – Optional  Insert images  Use actions buttons
  29. 29. Web Logs (Blogs) electronic journals Blogs are “part web site, part journal, part free-form writing spaces.”  Top 100 Education Blogs: http://oedb.org/library/features/top-100-education-blogs Blogger: https://www.blogger.com/ e.g.) http://makefilmpk.blogspot.com/ 29
