  1. How many states can a computer understand and what are they?
    2. On and Off
  2. How many counting digits are used in binary code? What numbers are they?
    Two digits  are used.  0 and 1.

  21. What motherboard form factor is this?
    AT Motherboard
  22. What motherboard form factor is this: 
    ATX Motherboard
  23. What are these called? Abbreviation and full name (the white slots) 

    What are they used for?
    PCI Bus Expansion Slots. Peripheral Component Interconnect. They are used for expansion cards such as sound cards and video cards.
  24. What is this Slot called? Acronym and full name. ��What is it used for?
    AGP. Accelerated Graphics Port.  It is only used for video cards.
  25. What is this slot called? (Acronym & name) Why is it better than it's predecessor?
    PCI-X Peripheral Component Interconnect Extended.  It has a 64 bit wide bus and is backwards compatible with older hardware/software.
  26. What is the name of the port that is used in laptops as an expansion bus port?
  27. What is the name of the faster more advanced slot that is normally used in computers today for an expansion bus?
    PCIe Peripheral Component Interconnect Express.
  28. Why is the PCIe better than it's predecessors? Explain why.
    Because it uses Serial communication instead of Parallel communication. In parallel communication two way traffic shares on wire which makes it slower. In serial communication the wires are dedicated to going one direction.
  29. In order, what are the 4 steps necessary steps for installing an expansion card?
    • Step 1: Knowledge
    • Step 2: Physical Installation
    • Step 3: Driver Installation
    • Step 4: Verify
  30. Explain step 1 for the expansion card installation process.
    Knowledge - you need to make sure that your device that you are installing is compatible with the computer you are installing it into.  Some older operating systems will not support newer hardware if a driver has not been issued for that hardware for that OS.
  31. Explain step 2 of the Expansion card installation process.
    Physical Installation- always protect against ESD first.  Make sure you hold the card by it's edges and not on the components. Once you are grounded with the chassis then make sure you use the correct angle when inserting the card.  Always secure the card in place (when it is sitting properly) with either a screw or sliding mechanism.
  32. Explain step 3 of the Expansion card installation process.
    device drivers - you need to make sure that you are installing the most updated drivers for that device.  You can get the drivers from a optical disk provided by the hardware or you can get it from the website for the hardware company.  Installing the most recent driver is probably the best but if you have issues then you may need to roll back to a previous driver.
  33. Explain step 4 of the Expansion card installation process.
    Verification - verify that the device is working properly.  Also open up Windows device manager and make sure the device is showing up. Finally put the card to the test by using it and making sure it works properly.
  34. What is the command you would enter into the command prompt in order to get the hardware wizard?
  35. What is the best way to choose a motherboard for a client or customer?
    1st choose what kind of MOBO you need.  Make sure it fits your chassis, fits the type of processor you want to use, and keep in mind how much RAM you may want to install now and in the future.  It is also important to look at expansion slots so that you can install new hardware in the future if needed. Also make sure there is a manual with the mobo so that you can verify how things should be set up.
