Question 1

is another name for a patch.

Accepted Answer

A patch, often referred to as a service release, is a set of changes to a computer program or its supporting data designed to update, fix, or improve it. This includes fixing security vulnerabilities and other bugs, and improving the usability or performance. AUTOEXEC.BAT is a system file that was originally on DOS-type operating systems, an upgrade is a complete new version of the software that offers significant changes or improvements, and a download simply refers to the act of transferring a file from the internet to a computer.

Question 2

Which of the following is NOT a major manufacturer of BIOS chips?

Accepted Answer

Logitech is a major manufacturer of computer peripherals, such as mice and keyboards, but not BIOS chips. The other options, AMI, Byosoft, and Phoenix, are all major manufacturers of BIOS chips.

Question 3

Jake was upset because the one beep that the computer normally emitted during the boot process stopped. He was concerned that the computer was malfunctioning even though the computer started without a problem. What is going on with his computer?

Accepted Answer

The beep that the computer emits during the boot process is a signal from the system speaker indicating that the computer is functioning correctly. If the beep is not heard, it is likely that the speaker has been disconnected or is faulty. However, since the computer is starting without a problem, it is unlikely that there is an issue with the CPU or memory. Similarly, unplugging the keyboard would not affect the system speaker.

Question 4

If the computer beeps once during POST and the computer has an AMI BIOS, what is the problem?

Accepted Answer

A single beep during POST with an AMI BIOS indicates that the DRAM refresh has passed without any errors. Therefore, there is no problem with the DRAM refresh. The other options are not relevant in this case.

Question 5

Hardware is checked out sequentially by the

Accepted Answer

The POST (Power-On Self Test) is a diagnostic routine that checks the hardware connected to the motherboard in a systematic sequence. It checks components such as the CPU, RAM, and graphics card and ensures they are functioning correctly before allowing the computer to boot up.

Question 6

POST is executed by the

Accepted Answer

POST (Power-On Self Test) is executed by the BIOS (Basic Input/Output System) chip. The BIOS chip is responsible for initializing and testing the system hardware components during the boot-up process. Therefore, the correct choice is option D. The other options (A, B, and C) are not related to the POST process.

Question 7

If a computer beeps once during POST, what is the problem?

Accepted Answer

A single beep during the Power-On Self-Test (POST) typically indicates that the computer has passed all diagnostic tests without any errors, meaning there is no problem with the hardware at this stage.

Question 8

Mitch Miller wants to use his optical drive to play a Moody Blues CD. When he inserts the disk and closes the drive tray, the drive turns, but he does not hear any music. What type of problem would a technician say this is?

Accepted Answer

The answer of Mitch Miller wants to use his optical...

Question 9

What BIOS manufacturer uses multiple beeps with pauses in between such as two beeps, pause, four beeps, pause, and then three beeps?

Accepted Answer

The pattern of multiple beeps with pauses in between is a part of the POST (Power On Self Test) process that BIOS (Basic Input/Output System) performs when a computer starts up. Different BIOS manufacturers have different beep codes to indicate system errors. In this case, the pattern of two beeps, pause, four beeps, pause, and then three beeps is specific to the Phoenix BIOS. Therefore, the best choice is D, Phoenix.

Question 10

Sarah became concerned because her computer beeped once each time she turned it on. She wondered what she was doing wrong, or what was going on with her computer. As an observing technician, what do you tell her?

Accepted Answer

A single beep when the computer is turned on is usually a normal indication that the computer has passed its power-on self-test (POST) and is functioning properly. Therefore, Sarah should relax because everything is fine.

Question 11

You see part of the following table in a POST reference manual:  The numbers refer to

Accepted Answer

The answer of You see part of the following table...

Question 12

The audio beeps heard during the boot process are caused by the

Accepted Answer

The beeps heard during the boot process are called beep codes, and they are typically produced by the BIOS (Basic Input/Output System). The BIOS is responsible for initializing and testing hardware components during the boot process, and it will generate beep codes if it detects any issues with these components. Therefore, the correct answer is C) BIOS.

Question 13

Hardware errors are often obvious during:

Accepted Answer

Hardware errors are often detected during POST (Power-On Self-Test) when the hardware devices are checked for proper functioning by the system BIOS. This test is performed during the boot-up process of a computer system. The other options may show symptoms of hardware errors but are not the best choice as they do not necessarily detect hardware errors specifically.

Question 14

What testing component could be installed into an expansion slot or attached to a USB port to perform hardware diagnostics and display the results on an LED display?

Accepted Answer

A POST (Power On Self Test) card can be installed into an expansion slot or attached to a USB port to perform hardware diagnostics and display the results on an LED display. This can be helpful in diagnosing hardware issues in a computer.

Question 15

A PC technician would most frequently rely upon which procedure to repair a PC?

Accepted Answer

Swapping parts is the most common procedure used by PC technicians to diagnose and fix PC issues. By swapping out faulty components with working ones, technicians can quickly isolate the source of the problem and replace the faulty part. Analyzing electrical conductivity using a probe and monitoring the clock cycle of a CPU using an oscilloscope are specialized procedures that are not commonly used in general PC repair. Monitoring motherboard LEDs may provide some information about the status of the system, but it is not a primary method for diagnosing and fixing PC problems.

Question 16

Jenny is having a difficult time using her new word processing program. While typing a document, she presses the Esc key and suddenly the monitor screen on her computer turns black. She presses the Esc key again and nothing happens. When she finally reboots the system, she hears a long beep followed by two short beeps. She watches in disbelief at what appears to be a dead computer and wonders what she did wrong to make the computer break. As an observing technician, what would you tell Jenny?

Accepted Answer

Pressing the Esc key and the computer problem of having a black screen and beeping sounds are most likely coincidental. There may be a video problem that caused the monitor to turn black and led to the beeping sounds during the reboot. It is not necessarily Jenny's fault or caused by her actions on the word processor.

Question 17

Which of the following helps determine whether a problem is hardware or software?

Accepted Answer

Listening to initialization beeps can help identify hardware problems, seeing if the problem occurs only in one application can help identify software problems, and looking up error codes can help identify both hardware and software problems. Therefore, all of these options can help determine whether a problem is hardware or software.

Question 18

You see part of the following table in a Phoenix BIOS reference:  The numbers refer to

Accepted Answer

The answer of You see part of the following table...

Question 19

What would be the purpose of the EPU motherboard LED?

Accepted Answer

The EPU motherboard LED is designed to show that the motherboard has been enabled to moderate power consumption efficiently. This feature allows the motherboard to conserve power and extend the lifespan of the system. It does not have anything to do with indicating issues with the CPU, RAM, or front panel connections.

Question 20

What is the best source for looking up a particular POST error code?

Accepted Answer

The motherboard documentation is the best source for looking up a particular POST error code as it will provide specific information about the hardware and BIOS settings related to the error. The AUTOEXEC.BAT and CONFIG.SYS files are related to the operating system and do not address hardware-related errors. The operating system manual may provide some information, but it is not as specific as the motherboard documentation. The hard drive manual is also not relevant in the context of a POST error code, as the error is related to the hardware components of the system rather than the hard drive specifically.
