  • ELCL605 Heejung An Week 2 1
  • What to do: Discussion Question for weeks 1-2 2
  • Computer Basics Hardware 3 View slide
  • 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. 4 View slide
  • 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. 5
  • 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) (e.g., Intel Pentium 4  Speed is measured in processor chip) MHz (megahertz). http://www.intel.com/ 6
  • 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. 7
  • Determining your computer’s CPU & RAM Start > Control Panel > System Processor type Amount of RAM 8
  • 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. 9
  • Scanner Allows you to capture and then translate printed copies or images into digital data. 10
  • Hardware: Output Devices Pieces of hardware that move information off of the computer :  e.g.) Monitor (soft copy) Printer (hard copy) Speaker, SmartBoard, Projector 11
  • Monitor The screen size refers to the number of inches measured diagonally across the screen. e.g.) 15’’, 17’’, 24’’ …. Resolution refers to the clarity and crispness of the images . on the monitor screen. 12
  • 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. 13
  • 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) 14
  • Hard Drive Status - Windows PC Start > My computer > Right click on the C drive (C:) > Properties 15
  • Hardware: Removable Storage Devices Floppy disk: 1.44 MB DVD-ROM (digital Zip disk: 100, 250, versatile discs): 4.7 GB and 750 MB CD-ROMs USB Flash Drive (compact-disc-read- (called jump drives only memory): 650 or keychain drives): MB 128 MB to 2 GB CD-Rs (recordable) CD-RWs (rewritable) 16
  • 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: 17
  • Accessing Drives: Windows PC Hard Drive C: Floppy Drive A: CD-ROM Drive D: Removable Drive E or F: 18
  • 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. 19
  • 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 20
  • Computer Basics Software 21
  • Software Software: the name given to the programs that you install on the computer to perform certain types of activities. Software Application Software Operating System (Application Software Program) 22
  • 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. e.g.) - Mac OS X for Apple • tells the computer how to Macintosh, - Windows and Linux OS for a function and how to PC, manage its own operations. - The Palm OS for Palm Pilots. 23
  • 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. 24
  • 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. 25
  • 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. 26
  • Presentation Software Includes programs that are designed for creating digital support materials for presentations. e.g.) - Microsoft PowerPoint - Apple Keynote 27
  • Lab…continued Technical aspects:  Use a master slide  Use animation effects somewhere in the presentation  Slide transitions – Optional  Insert images  Use actions buttons 28
  • 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
