Hardware

• Hardware is a term for the physical components
  that are included when you purchase a PC. They
  include the system box, monitor, keyboard and
  mouse. 

6
CPU

• Central Processing Unit is the main processor of
  the computer, located in the tower, desktop box,
  or under the keyboard of a laptop. It may be
  thought of as the brains of your computer. It
  takes instructions from software, makes
  calculations and helps run the show.
• We measure the central processing unit's (CPU)
  speed in megahertz (MHz). Megahertz is a unit of
  measurement commonly used to compare the speeds
  of computers. The higher the CPU's megahertz
  rate, the faster it processes information and
  instructions.

7
Memory

• RAM is the computer's primary working
  memory. RAM is used for short-term storage while
  the computer does its work. It is read/write
  memory. RAM is distinguished from ROM, which is
  read-only memory. The more RAM you have the more
  your computer can do at one time. RAM is
  volatile memory. It needs to be running to
  "remember" what it is doing. In case of a system
  failure or power interruption, you will lose all
  of your work in RAM that you have not saved on a
  disk drive. Save your work frequently. 

8
Storage

• Storage is where the program is kept, RAM is
  where it works. The amount of space a program
  needs for storage on the hard drive has nothing
  to do with how much RAM is needed to run the
  program. Many PC programs take up several
  megabytes of storage space. Many programs also
  require at least 16MB to 32MB (or more) of
  RAM. To run today's popular programs, make sure
  your computer has adequate RAM and storage.

9
Disk Drives

• Disk drives allow you to store and move data
  from, and to, different types of media. There
  are several types of drives floppy drive, hard
  drive, CD-ROM drive, and DVD drive. 

10
Floppy Drive

• A floppy disk drive is an economical, removable
  storage medium. It uses a magnetic disk. You can
  record or erase it and then remove it from the
  computer. You can use the removable disk
  repeatedly. Today's floppy is 3.5 inches of
  square, stiff plastic with a magnetic disk
  inside. To read or write to a floppy disk,
  insert the disk into the floppy disk drive slot
  on the front of your CPU.

11
Hard Drive

• The hard disk, or hard drive, is your PC's main
  storage device. It's sometimes called the C/
  drive, and pronounced "cee" drive. Data is
  magnetically stored there. It stores programs and
  data files. A typical hard disk holds from 1 to
  10 gigabytes of storage. Much larger hard drive
  capacity is available.

12
CD-ROM Drive

• CD-ROMs are compact discs, read-only, removable
  storage media. CD-ROMs read the data encoded on
  the disc and then transfer this data to the
  computer.CD-ROMs are different from hard drives
  and floppy disks, in that you cannot store your
  own information on them. One CD-ROM can hold as
  much information as about 450 floppy
  diskettes. Recently, the creation of RW CD-ROM
  drive appeared this is a re-writeable CD-ROM
  drive. It allows you to read, erase, and use it
  repeatedly like a floppy drive.

13
Output Devices

• Output devices enable you to store, print or
  display the data that has been processed. Some
  examples of output devices are the monitor,
  printer and various disk drives.

14
DVD Drive

• DVD stands for digital versatile disk. DVD
  drives read DVDs. A DVD holds about 5 gigabytes
  of information while a CD-ROM only holds about
  600 megabytes. A CD-ROM drive cannot read a DVD.
  However, DVD drives can read CD-ROMs.
• Unfortunately, the Holland School does not have
  any computers with DVD drives yet.

15
Monitor

• All computers are connected to some type of
  display, which usually is called the monitor.
  Sometimes we call the monitor a CRT (cathode ray
  tube) and sometimes we refer to it as a video
  display unit. The monitor attaches to the video
  output of the computer and produces a visual
  display. Monitors are available in many
  different types and sizes. The size generally
  goes from 12 to 21 inches diagonal.

16
Printer

• A printer is a device that accepts text and
  graphic output from a computer and transfers the
  information to paper, usually to standard size
  sheets of paper. Printers vary in size, speed,
  sophistication, and cost. In general, more
  expensive printers are used for higher-resolution
  color printing.

17
Input Devices

• Input devices enable you to give commands or
  provide data for the process. Examples of an
  input device are keyboard, mouse, joystick, and
  a scanner.

18
Keyboard

• On most computers, a keyboard is the primary text
  input device. The keyboard also contains certain
  standard function keys, such as the Escape key,
  tab and cursor movement keys, shift and control
  keys, and sometimes other manufacturer-customized
  keys.
• The computer keyboard uses the same key
  arrangement as the mechanical and electronic
  typewriter keyboards that preceded the computer.

19
Mouse

• A mouse is a small device that a computer user
  pushes across a desk surface in order to point
  to. A mouse consists of a metal or plastic
  housing or casing, a ball that sticks out of the
  bottom of the casing and is rolled on a flat
  surface, one or more buttons on the top of the
  casing, and a cable that connects the mouse to
  the computer. As the ball is moved over the
  surface in any direction, a sensor sends impulses
  to the computer that causes a mouse-responsive
  program to reposition a visible indicator (called
  a cursor) on the display screen. The positioning
  is relative to some variable starting place.
  Viewing the cursor's present position, the user
  readjusts the position by moving the mouse.

20
Scanner

• A scanner captures images from photographic
  prints, posters, magazine pages, and similar
  sources for computer editing and display.
  Scanners come in hand-held, feed-in, and flatbed
  types and for scanning black-and-white only or
  color. Very high resolution scanners are used for
  scanning for high-resolution printing, but lower
  resolution scanners are adequate for capturing
  images for computer display. Scanners usually
  come with software, such as Adobe's Photoshop
  product, that lets you resize and otherwise
  modify a captured image.
• The Holland School has a scanner in each of the
  computer labs and the library.

21
Local Area Network

• Local Area Network or LAN is a computer network
  limited to the immediate area, usually the same
  building. A LAN is a network that is confined to
  a relatively small area. It is generally limited
  to a geographic area such as a writing lab,
  school or building.
• The Holland School has a Local Area Network
  within the building.

22
Ethernet

• Ethernet is a system for connecting computers
  within a building using hardware running from
  machine to machine. It is a Local Area Network
  (LAN) protocol developed by Xerox and DED
  (Digital Equipment Corporation) that allows data
  transfer rates of 10Mbps often called 10Base-T,
  10Base-2 or 10Base-5. The differences designate
  the type of cable used.
• Ethernet is the protocol the Holland School uses
  to access our network and the World Wide Web.

Assembling Classroom Computers

• The process of assembling a computer has become
  drastically easier as time has marched on. Our
  classroom computers have these basic components
  CPU, monitor, keyboard, mouse, network cable,
  power cables and printer. We will now begin the
  process of assembling your classroom computer.
  Once again, if you do not feel comfortable
  completing any task that is involved in the
  process of setting up your classroom computer,
  just ask for assistance. We will walk through all
  the steps together, so relax and enjoy!

25
Computer Assembly

• Place the CPU, monitor, keyboard, mouse and
  printer on your classroom computer table.
• CPU The CPU has a power cord attached that we
  will plug into an outlet when we are finished.
• Monitor There are 2 cables that are attached to
  the back of the monitor. One is a power cord that
  we will plug into an electrical outlet when we
  are done. The other cable connects to the back of
  the CPU. The monitor cable has little pins
  surrounded by metal casing. There are also two
  screws on the outside of the casing. Believe it
  or not the cable will only fit into one place on
  the back of the computer, which has little holes
  that will receive the pins on the cable. Simply
  insert the monitor cable into the CPU and tighten
  the screws. You shouldnt have to be very
  forceful with the connection, if you need to
  force the cable in it is probably not aligned
  correctly.

26
Computer Assembly

• Keyboard The keyboard has a cable that connects
  to the back of the CPU. This cable is also has
  pins in a circle surrounded by metal casing. The
  cable is color-coded. Simply go to the back of
  the CPU and find the matching color and insert
  the cable. There is also a picture of keyboard
  directly above the insertion place. Remember if
  you have to use excessive force, the cable is
  probably not aligned correctly.
• Mouse The mouse also has a cable that connects
  to the back of the CPU. This cable also has pins
  in a circle surrounded by metal casing. This
  cable is also color-coded. Again, go to the back
  of the CPU and find the matching color and insert
  the cable. There is also a picture of a mouse
  directly above the insertion place. Remember if
  you have to use excessive force, the cable is
  probably not aligned correctly.

27
Computer Assembly

• Network Cable The Network Cable looks like a
  phone cable and fits into the area on the back of
  the CPU that looks just like a phone jack. The
  other end of the Network Cable plugs into the
  network jack on the wall, once again it inserts
  just like a phone cord.
• Printer Our printers are connected to our Local
  Area Network. The printer has a power cord and
  Network Cable. Insert the Network Cable into the
  network jack on the wall, once again it inserts
  just like a phone cord. Now plug in the power
  cord into an outlet in the wall.
• Finally, plug in the power cords from the monitor
  and CPU. We are now ready to start up the
  computer!

Start Up

• When you turn on your computer it begins the
  process of booting up. This is a term for
  starting your personal computer. It initiates an
  automatic routine that clears the memory, loads
  the operating system, and prepares the computer
  for use. 
• After the start-up, what you should see on the
  monitor is the Windows Desktop. It is the home
  base like the physical desk where your computer
  sits. Several tools to get you started are placed
  on the background area. These include a taskbar,
  icons, and a Start button. There will be
  variations from computer to computer on what the
  Desktop looks like.

31
Shut Down

• It is important to use the correct shutdown
  procedure. You should never just shut off your
  computer. Before you shut down, always save the
  files you are working on. Always close Windows
  before shutting down your computer. This will
  help to protect your files from data corruption. 

• To shut down Click the Start button and select
  Shut Down.  Select the Shut Down option. 
  Click the OK or yes button.  You will see a
  screen that tells you it is safe to turn off your
  PC. Turn off the power to your computer. Do not
  forget to turn off the monitor, too.

Basic Troubleshooting

• There are some problems that may arise

34
Computer Doesnt Work

• Double check to make sure the computer and
  monitor are plugged in.
• If you are using a power strip, make sure it is
  on. If the power strip is on and the computer
  still doesnt work, plug the computer directly
  into a wall outlet instead.
• If the problem persists, plug the computer into a
  different outlet in case there is a problem with
  the outlet itself.
• Check the adjustment of the contrast on your
  monitor, youll be surprised how often the
  students turn it down.

35
Out of Memory Error

• If you have more than one program running, close
  any of the programs you are not using.
• If the problem persists, reboot the computer.
• If the error message appears frequently, you may
  need more memory. See your Technology Specialist
  for more assistance.

36
Mouse Doesnt Work

• Make sure the mouse is properly connected to the
  computer.
• Clean the ball of the mouse and then reboot the
  computer, see your technology specialist for more
  assistance in this instance.

37
Frozen Computer

• Press Ctrl Alt Del at the same time to bring
  up the Task List. Close any program that is
  listed as Not Responding.
• If this does not solve the problem, turn off the
  computer, wait a minute, then restart.

38
Printer Doesnt Work

• Make sure the printer is plugged in and turned
  on.
• Check to make sure there is paper in the printer.

39
Cant Log Onto Network

• Check to make sure the Network Cable is plugged
  into the CPU and the network jack on the wall.
• Check to see if there is a green light on the
  back of the CPU next to the Network Cable.
• Make sure you are using the correct username
  password. Remember they are case sensitive.

Password Protection

• Each staff member of the Holland School has been
  given a random and unique username and password
  by the Office of Information Systems.This
  username and password enables staff to access our
  network and a variety of on-line teacher
  resources including student report cards, student
  attendance, student assessments, emergency
  information, etc. The number of resources is
  growing daily and we must fight to ensure privacy
  rights of all. Remember, these wonderful
  resources bring with them additional
  responsibility.

42
Password Protection

• It is imperative to ensure the privacy of your
  username and password. Therefore you should
  never share this information with anyone else.
  Remember, the information you have access to via
  this username and password is often private by
  law. Please secure your username and password as
  you would your ATM password.

Back-up

• Imagine losing all your work when the power
  fails
• Imagine if your computer were to be stolen
• Imagine if your hard drive crashes
• I can not stress enough the importance of
  continually backing up all your work.
• Please do not rely on your hard drive to store
  all your files.
• You should also stores copies on a floppy disk
  or your folder on the network.
• Back-up, back-up, back-up.

45
Back-up

• When should I back up?
• As a matter of routine.
• To protect yourself against accidental data loss,
  you should back up your files according to a
  regular schedule (e.g., every Friday afternoon).
  You may also choose to back up each file whenever
  you make changes to it, this is strongly
  suggested.
• Before your computer is repaired or has new
  software installed.
• You must back up your files before any hardware
  or software repairs or upgrades can be performed.
  
• Before you get a new computer.
• If you are moving to a different computer, you
  must back up any files which need to be
  transferred to your new machine. All files left
  on the hard drive of your old computer will be
  lost.
