Chapter 1 Reviewing the Basics Questions
1. SuperSpeed USB 3.0 is faster than Hi-Speed 2.0
2. A S/PDIF sound port connects to an external home theater audio system, providing digital audio output and the best signal quality.
3. Video Graphics Array, S-Video, Digital Video Interface, High-Definition Multimedia Interface and Display Port.
4. A motherboard has expansion slots to be used by expansion cards. An expansion card, also called an adapter card, is a circuit board that provides more ports that those provided by the mother board.
5. Most power supplies have a dual-voltage selector switch on the back of the computer case where you can switch the input voltage to the power supply ...view middle of the document...
9. A surge suppressor protects electrical equipment from power surges and is rated in joules.
10. A power supply receives 120 volts of Alternating current power from a wall outlet and converts it to 3.3, 5, and 12 volts of Direct Current power.
11. Power supplies and CRT monitors contain capacitors. A capacitor holds its charge even after the power is turned off and the device is unplugged.
12. The best way to guard against ESD is to use a ground bracelet together with a ground mat or wear antistatic gloves.
13. The power-on self-test is a series of tests performed by the startup BIOS when you first turn on a computer. These tests determine if startup BIOS can communicate correctly with essential hardware components required for a successful boot.
a. System BIOS manages essential devices (such as keyboard, mouse, hard drive, and monitor) before the OS is launched.
b. Startup BIOS is used to start the computer.
c. BIOS setup or CMOS setup is used to change the motherboard configuration or settings.
15. The best way to know for sure what type of cable you're dealing with, trace the cable from its source to its destination.
16. A serial ATA or parallel ATA.
17. When faster PCI express (PCIe) slots were added to motherboards, more powReer was required and a new ATX specification (ATX Version 2.2) allowed for a 24-pin P1 connector.
18. A 6-pin PCIe connector provides an extra +12 V for high-end video cards using PCI Express, Version 1 standard.
19. A 4-pin auxiliary motherboard connector used for extra 12 V power to the processor.
20. A 4-pin Molex connector is used for IDE (PATA) drives.
