PowerPoint Lesson #1

the kinds of computers
The Kinds Of Computers

There are essentially 4 categories of Computers

  • One “main-mast” server
    • Holds huge amounts of information
    • Usually the center of a network
      • Maintains integrity of attached/detached network computers
      • Hold a little bit of data for each computer
    • Controls the entire infrastructure
    • Sometimes can be connected to via a Remote Desktop Connection

  • The “Internet” is….
    • Not one big server
      • It is actually all of our computers hooked together by connections
    • Not owned by one person
      • All of us own it equally
    • A connection to websites
      • Every website is stored on a server somewhere. The only thing controlled by the government is the domain name (ex:
  • A desktop is….
    • More commonly referred to as a Personal Computer (PC)
    • A single computer that connects to a network
    • A hardware group consisting of
      • A Monitor (if included)
      • A CPU
      • A Keyboard
      • A Mouse
    • Smaller than a Server by far!
  • A Laptop is…
    • A portable computer
    • Smaller than a Desktop
      • This makes its limiting factor weight and size:
        • Less capabilities for larger and better components
        • More fragile
        • Less upgrade capability
        • Does not run off of a continuous AC power supply
    • A device that connects to the internet via wireless adapter/card
    • Usually combines mouse, keyboard, and monitor

  • An Adapter is a device that connects to a computer to give it extra functionality:
    • An Internet Connection
    • A RJ-45 Connection (Wired Connection)
    • Some extra hardware connection
  • A Router is a device that intercept wireless pings (connection attempts) and (upon connection) transfers data to and from the connected device.

    • Wireless Adapter  Router  Internet
    • RJ-45 Connection  Router or RJ-45 Outlet  Internet
    • Dial-Up  Internet
    • Dial-Up  Modem (allows for greater speed)  Internet
    • Wireless DeviceWireless Tower  Internet
portable devices
Portable Devices
  • Any device that utilizes basic input commands and gives out a result (output).
  • Types of Portable Devices:
    • Cell Phones
    • MP3 Players
    • PDA’s
    • Walk – and - Talkies
    • Calculators
    • Etc.
  • Some of these devices can access the internet but others cannot:
