ISDN uses which of the following technologies?
| ( | A | ) | | Digital and analog |
 |
| ( | B | ) | | Only analog |
|
| ( | C | ) | | Only digital |
|
| ( | D | ) | | Laser diode |
|
| ( | E | ) | | None of the above |
The Correct Answer is: C
The most chosen answer was [ A ] :: [ Digital and analog ]
Explanation:
ISDN uses only digital signals to transfer data packets.
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.
Which of the following DRAM types is the fastest?
(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
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
What are the two files that the Windows 95 Registry is composed of?
(this question provided by simulationexams.com)
| ( | A | ) | | SYSTEM.COM, USER.DAT |
|
| ( | B | ) | | SYSTEM.DAT, USER.DAT |
|
| ( | C | ) | | USER.DAT, SYSTEM.COM |
|
| ( | D | ) | | IOSYS.COM, USER.DAT |
|
| ( | E | ) | | None of the above |
The Correct Answer is: B
Explanation:
The Windows 95/98 system
files include the following:
A.
IO.SYS
B.
MSDOS.SYS
C.
WIN.INI
D.
COMMAND.COM
E.
SYSTEM.INI
F.
SYSTEM.DAT
G.
USER.DAT
MSDOS.SYS, WIN.INI,
SYSTEM.INI are text files.
SYSTEM.DAT, USER.DAT files are part of windows Registry and can be edited using
REGEDIT or REGDT32 utility. Further, USER.DAT file corresponds to
HKEY_LOCAL_USER and SYSTEM.DAT corresponds to HKEY_LOCAL_MACHINE.
Registry files can't be read with standard text editors.
