Motherboard

• The Motherboard is the heart and brains of the
  computer.
• The Hard Disk stores all the info and data.
• On the Motherboard you will find a few expansion
  cards.
• The Sound Card contains special circuits for the
  computers sound.
• The Modem is a card that allows computers to talk
  to each other.
• These parts are all stored on the Motherboard.

E-mail

If you wanted to send a message to your friend
like Want to go to lunch then you would type
the message including the persons ISP or E-mail
address. Then your mail sever would read the
address and decide the best route to take. It
then sends the message to your friends mail
server. There it is kept in an electronic mailbox
until your friend opens it. Computers must have a
POP server, such as Outlook, America Online, etc,
to open and read emails.

The Virus Effect

• All viruses but Trojan Horses can duplicate
  themselves.
• Viruses can be many things, but the main ones are
  Worms,
• Trojan Horses, and Viruses. Some viruses
  duplicate
• themselves but are harmless. If a virus gets in a
  computer
• it can cut off a whole region in hours! Its
  against the law to
• purposely send out a virus.

How the Internet Connects Worldwide

• The internet connects using routers and protocol
  which is rules to how to communicate.
• Routers are special computers inside regular
  computers that send your messages and E-mails to
  destinations in the internet through thousands of
  pathways.
• Your modem changes the signals in your computer
  into signals that are able to travel through
  electronic power lines.
• Your ISP, or addresss, allows you to connect to
  the Internet.

The Complete Computer

• The computer is made up of many parts such as
  the CPU, the ROM
• (Read-Only Memory) and RAM (random access
  memory), the Modem,
• Hard Drive, Circuit Board, Ports, and Interface.
  The Hard Drive has magnetic
• disks that store all info you save on your
  computer. RAM and ROM are the
• memory on your computer. RAM is short term memory
  and ROM is permanent memory. Ports are on the
  outside of your computer and allow
• you to connect hardware. The CPU (Central
  Processing Unit) located on the
• Motherboard is the brain of a computer and
  instructs the other parts of the
• computer.

Hard Drive

• The Hard Drive stores all the data that is
  saved. The Hard Drive is made up of magnetic
  spinning discs that are made of polished steel.
  On the surface you will find cylinders or tracks.
  When your computer says it is loading, it is
  searching the Hard Drive for the information. The
  larger your Hard Drive the more data your
  computer can store.

Binary Code

• Binary code is the language made of 1s and 0s,
  that the computer understands.
• When you press a key, it closes and opens tiny
  doors. Open is a 1 and closed is a 0.
• These numbers get sent to the CPU that translates
  the numbers into text and are next sent to the
  monitor.
• A bit is a 1 or a 0. 8 bits a byte.
• kilobyte 1,000 bytes
• megabyte 1,000,000 bytes
• gigabyte 1,000,000,000 bytes

Fun Facts

• When computers were first invented they filled a
  room 30 by 50 feet.
• Your Hard Drive can spin up to 3,600 times per
  minute.
• A CPU generates so much heat that it usually
  needs a small fan to cool it down.
• Most computers have a CD-ROM, but new computers
  have a CD-RW which allows you to rewrite the
  information on the disc.
• Each byte holds eight bits capable of making 256
  codes of 1s and 0s.
• Every day the people send each other billions of
  e-mails a day.
