Direction: Identify the following statement.

 _________1. Define as the flow of electron or electric current. It is an invisible form of energy that can be transform into other form of energy like heat light and mechanical.

 _________2. The negatively charge component of an atom. It has the ability to flow. 

_________3. Define as the opposition to the flow of current. The amount of resistance can be measure in ohms (Ω). _________

4. The positively charge component of an atom. It has the ability to attract electron.

 _________5. Anything that occupy space and has mass. It can be a solid, liquid or gas in state.

 _________6. Basic component of matter. It composes of a nucleus which is the central part, the protons and electrons.

 _________7. Same as electricity or flow of electron. The amount of current flowing in a circuit can be measured in ampere (I).

 _________8. The amount of pulling force that makes the electron flow. Also known as potential difference or EMF (electromotive force). The amount of voltage can be measured in volt (V).

 _________9. Materials that easily allow the flow of current, or it has a low resistance to current flow.

 _________10. Materials that do not easily allow the flow of current, or it has a high resistance to current flow.

 _________11. A computer power supply converts AC to ___________________. 

_________12. Define as the pathways for electricity to flow. 

_________13. A component of a circuit that is commonly represented by a bulb or any electrical component that consumes electricity. 

_________14. A component of a circuit that is commonly represented by a cell or a battery.

_________15. An electrical device that opens or closed a circuit.

 _________16. A type of circuit that has a closed path for current to flow. It means that current can flow in this circuit.

 _________17. A type of circuit that has an open path for current to flow. It means that current cannot flow in this circuit.

 _________18. A circuit connection has only one path of current flow. In this circuit connection the current remain constant.

 _________19. A circuit connection that has 2 or more path of current. In this circuit the voltage remains constant.

 _________20. An invisible form of energy. 

1. Look at the back of your computer. Without opening the case, list the ports that you believe come directly from the motherboard. 

2. Remove the cover of the case. List the different expansion cards in the expansion slots. Was your guess correct about which ports come from the motherboard? 

3. To expose the motherboard so you can identify its parts, remove all the expansion cards. 

4. Draw a diagram of the motherboard and label these parts: Processor (Include the prominent label on the processor housing.) 

a) RAM (each DIMM slot) 

b) CMOS battery 

c) Expansion slots (Identify the slots as PCI, PCIe x1, PCIe x4, PCIe x16, and AGP.) 

Each port coming directly from the motherboard Power supply connections, SATA or IDE drive connectors and floppy drive connector 

5. Draw a rectangle on the diagram to represent each bank of jumpers on the board. 

6. What is the brand and model of the motherboard? 

7. Locate the manufacturer’s Web site. If you can find the motherboard manual on the site, download it. 8. You can complete the following activity only if you have the documentation for the motherboard:
