The power supply cords to the motherboard provide the correct voltage, and the connectors match theconnections on the board.The holes in the motherboard align with the holes in the case for anchoring the board to the case.The holes in the case align with ports coming off the motherboard.For some form factors, wires for switches and lights on the front of the case match up with connectionson the motherboard.The holes in the power supply align with holes in the case for anchoring the power supply to the case.PTS:1REF:95.Describe the PATA interface.ANS:The PATA interface, also called the IDE interface, uses a wide 40-pin ribbon cable and connector. Thestandard allows for only two connectors on a motherboard for two data cables.Each IDE ribboncable has a connection at the other end for an IDE drive and a connection in the middle of the cable fora second IDE drive.Using this interface, a motherboard can accommodate up to four IDE or PATAdrives in one system.PATA drives use a 4-pin power connector called a Molex power connector. AMolex connector is shaped so it connects in only one direction.PTS:1REF:206.What is the difference between AC and DC electricity?ANS:Electricity can be either AC, alternating current, or DC, direct current. Alternating current (AC) goesback and forth, or oscillates, rather than traveling in only one direction.Voltage in the system isconstantly alternating from positive to negative, which causes the electricity to flow first in onedirection and then in the other.Direct current (DC) travels in only one direction and is the type ofcurrent that most electronic devices require, including computers.PTS:1REF:267.What is the purpose of the 3-wires in an AC electrical system?ANS:AC travels on a hot line from the power station to a building and returns to thepower station on aneutral line. When the two lines reach the building and enter an electrical device, such as a lamp, thedevice controls the flow of electricity between the hot and neutral lines.If an easier path (one withless resistance) is available, the electricity follows that path. This can cause a short, a sudden increasein flow that can also create a sudden increase in temperature—enough to start a fire and injure bothpeople and equipment.To prevent uncontrolled electricity in a short, the neutral line is grounded.Grounding a line means that the line is connected directly to the earth, so that, in the event of a short,the electricity flows into the earth and not back to the power station.PTS:1REF:268.List three indications of a potential electrical danger.ANS:The power cord is frayed or otherwise damaged in any way.Water or other liquid is on the floor around the device or spilled on it.The device has been exposed to excess moisture.The device has been dropped or you notice physical damage.

You smell a strong electronics odor.The power supply or fans are making a whining noise.You notice smoke coming from the computer case or the case feels unusually warm.PTS:1REF:289.What is the description of and purpose of a ground bracelet?ANS:A ground bracelet, also called an ESD strap, antistatic wrist strap, or ESD bracelet, is a strap you weararound your wrist. The strap has a cord attached with an alligator clip on the end. Attach the clip to thecomputer case you’re working on. Any static electricity between you and the case is now discharged.Therefore, as you work inside the case, you will not damage the components with static electricity.The bracelet also contains a resistor that prevents electricity from harming you.PTS:1REF:3010.List three of the six rules you should follow to protect computer parts against ESD.ANS:Rule 1: When passing a circuit board, memory module, or other sensitive component to anotherperson, ground yourself and then touch the other person before you pass the component.Rule 2: Leave components inside their protective bags until you are ready to use them.Rule 3: Work on hard floors, not carpet, or use antistatic spray on the carpets.Rule 4: Don’t work on a computer if you or the computer have just come in from the cold becausethere is more danger of ESD when the atmosphere is cold and dry.Rule 5: When unpacking hardware or software, remove the packing tape and cellophane from the workarea as soon as possible because these materials attract ESD.Rule 6: Keep components away from your hair and clothing.PTS:1REF:33

ANS:Video cards draw the most power. Video cards draw the most power in a system, and they draw fromthe +12 V output. If your system has a video card, pay particular attention to the +12 V rating. Thetrend nowadays is for the motherboard to provide the video components and video port, thus reducingthe overall wattage needs for a system.The power supply should be rated about 30 percent higher than expected needs. Power supplies thatrun at less than peak performance last longer and don’t overheat. In addition, a power supply losessome of its capacity over time. Also, don’t worry about a higher rated power supply using too muchelectricity. Components only draw what they need.PTS:1REF:75
