IT Essentials Chapter 3 Quiz Answers Online

Part 1 describes a processor or CPU. Athlon is an AMD processor. CPUs are installed into a processor socket and secured by lowering and securing the load lever.​

A Gigawhiz GA-A239VM is a type of motherboard since it mentions front panel connectors. The system panel connector is used to attach cables between the motherboard and the front of the case for USB ports, power button, microphone jack, headphones jack, etc. Standoffs keep the motherboard from grounding to the case. The holes in the motherboard should align to the standoffs. Each standoff screws into the case. Then screws are used to securely attach the motherboard to the case (via the standoffs).

Cases, motherboards, and power supplies all come in the ATX form factor, but cases are the only ones that have drive bays.

Part 6 is a power supply. Power supplies have fans that provide proper air flow through the interior of the computer case. Power supplies should be tightly screwed to the case (but not over tightened) so that the fan vibrations do not loosen it.

The BIOS contains a power on self test (POST) program that tests hardware during computer startup. One beep is a common indication that all is well. Several beeps indicate a hardware issue. BIOS is built into the motherboard, so it is the motherboard documentation that should be consulted to resolve this issue.

Before you install a memory module it is important to verify that there are no compatibility issues. A DDR3 RAM module will not fit in a DDR2 slot. Verification is best done by consulting the motherboard documentation or checking on the website of the manufacturer.

The Advanced Technology Extended (ATX) main power connector will have either 20 or 24 pins. The power supply may also have a 4-pin or 6-pin Auxiliary (AUX) power connector that connects to the motherboard. A 20-pin connector will work in a motherboard with a 24-pin socket.

The BIOS configuration data is saved to a special memory chip called a Complementary Metal Oxide Semiconductor (CMOS).

Go to the motherboard manufacturer site to get the correct software to update the BIOS.

After the new motherboard is in place and cables are connected, you should install and secure all expansion cards. Finally, connect the keyboard, mouse, and monitor, then power on the computer to check for problems.

The computer time and date are held in CMOS. This requires power from a small battery. If the battery is getting low, the system time and date may become incorrect.

The BIOS setup program is used to change settings if memory modules, storage devices, and adaptor cards are added. Most manufacturers provide the ability to modify boot device options, security and power settings, and adjustments for voltage and clock settings.

Increasing the CPU clock speed will make the computer run faster, but also generate more heat and cause overheating issues.

When reinstalling the heat sink, clean the base of the heat sink with isopropyl alcohol. This removes all traces of old thermal compound so the newly applied thermal compound works properly.

A signed driver is a driver that has passed the Windows hardware quality lab test and has been given a driver signature by Microsoft. Installing an unsigned driver can cause system instability, error messages, and boot problems.
