(this question provided by simulationexams.com)
| ( | A | ) | | Conventional DRAM |
 |
| ( | B | ) | | FPM DRAM |
|
| ( | C | ) | | EDO DRAM |
|
| ( | D | ) | | BEDO DRAM |
|
| ( | E | ) | | None of the above |
The Correct Answer is: D
The most chosen answer was [ B ] :: [ FPM DRAM ]
Explanation:
The following are basic types
of DRAM:
1.
Conventional DRAM
2.
Fast Page Mode DRAM
3.
Extended Data Out (EDO) DRAM
4.
Burst Extended Data Out (BEDO) DRAM
FPM DRAM typically allows
burst system timing of 5-3-3-3 at 66MHz
EDO DRAM typically allows
burst system timing of 5-2-2-2 at 66MHz
BEDO DRAM typically allows
burst system timing of 5-1-1-1 at 66MHz
When working on a user's PC you notice that the fan on the power supply is excessively dusty. After turning the PC off, what would you use to clean it?
| ( | A | ) | | Spray bottle of Windex |
|
| ( | B | ) | | A toothe brush |
|
| ( | C | ) | | Compressed air |
|
| ( | D | ) | | A damp paper towel |
|
| ( | E | ) | | A vacuum cleaner |
The Correct Answer is: C
Explanation:
The best thing to use would be a can of "Compressed air." You are least likely to cause damage when using it correctly. When using Compressed air, hold the can at least 6 inches from the target.
IRQ2 is used with which of the following?
(this question provided by simulationexams.com)
| ( | A | ) | | COM1 |
|
| ( | B | ) | | COM2 |
|
| ( | C | ) | | LPT1 |
|
| ( | D | ) | | Used to cascade the second IRQ controller |
|
| ( | E | ) | | None of the above |
The Correct Answer is: D
Explanation:
The IRQ numbers and relevant Standard Device
Assignment are given below. It is important to memorize these values before
going to the exam, as there would be 5-10 questions on IRQs, and conflicts.

| 13 |
Math co-processor |
| 14 |
Primary hard-disk IDE controller |
| 15 |
Secondary hard-disk controller |
You are reported that the monitor at a client's place is having a problem. You are about to remove the cover of the monitor. What do you do just before opening the monitor cover? Choose all that apply.
(this question provided by simulationexams.com)
| ( | A | ) | | Wear wrist strap to prevent ESD damage to the monitor |
|
| ( | B | ) | | Make sure that the power is switched off and the power cord is plugged out |
|
| ( | C | ) | | Make sure that the ESD is grounded properly |
|
| ( | D | ) | | Connect the Monitor as well as the wrist strap to the ground. |
|
| ( | E | ) | | All of the above |
The Correct Answer is: B
Explanation:
Never wear a wrist strap when working on monitors.
Monitors contain very high voltages, sometimes fatal to human, even when the
power is turned off. If you are wearing wrist strap, the human body work as a
conduit to discharge the electric charge.
Which function key is pressed to bypass CONFIG.SYS, and AUTOEXEC.BAT during the DOS boot process?
(this question provided by simulationexams.com)
| ( | A | ) | | F6 |
|
| ( | B | ) | | F8 |
|
| ( | C | ) | | F4 |
|
| ( | D | ) | | F5 |
|
| ( | E | ) | | None of the above |
The Correct Answer is: D
Explanation:
To bypass the CONFIG.SYS, and AUTOEXEC.BAT files during boot process of DOS, you need to press F5. F8 allows you to selectively bypass commands in AUTOEXEC.BAT, and CONFIG.SYS.
