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.
Which control signal on a serial cable, indicates that the data set is ready?
(this question provided by simulationexams.com)
| ( | A | ) | | DTR |
|
| ( | B | ) | | DSR |
|
| ( | C | ) | | RTS |
|
| ( | D | ) | | CTS |
|
| ( | E | ) | | None of the above |
The Correct Answer is: B
Explanation:
COM1, COM2 on a computer uses a serial cable. The pin
assignments are shown below. The computer acts as a DTE (Data Terminal Equipment)
and the Modem acts as DCE (Data Communication Equipment).
Signal--Name---------DB9 Pin
RX------Received Data--2
TX------Transmitted Data-3
DTR-----Data Terminal Ready--4
GND---- Ground--5
DSR---- Data Set Ready--6
RTS---- Request to Send--7
CTS---- Clear to send--8
Normally, a DTE device connects to a DCE device
with a straight cable. If you want to connect two DTR devices, as you would do
to hook up two computers via the serial line to exchange files, the cable itself
must have cross connections. Such a cable is called a null modem cable.
Which of the following is the port address for serial port COM1?
(this question provided by simulationexams.com)
| ( | A | ) | | 3F0-3F7 |
|
| ( | B | ) | | 2F8-2FF |
|
| ( | C | ) | | 320-32F |
|
| ( | D | ) | | 3F8-3FF |
|
| ( | E | ) | | None of the above |
The Correct Answer is: D
Explanation:
You need to memorize the following port addresses
before attending the exam.
Port-Base
address (in hex)
COM4:
2E8-2EF
COM2:
2F8-2FF
COM3:
3E8-3EF
COM1:
3F8-3FF
LPT2 :
278-27F
LPT1 :
378-37F
Floppy Controller:
3F0-3F7
Hard Drive Controller, 16
bit, ISA: 1F0-1F8
What tool would be used to check for line voltage sags?
| ( | A | ) | | Surge protector |
|
| ( | B | ) | | Feedback circuit |
|
| ( | C | ) | | Terminal adapter |
|
| ( | D | ) | | Polarity tester |
|
| ( | E | ) | | High frequency monitor |
The Correct Answer is: D
Explanation:
A Polarity tester is useful whenever there is a need to check for the presence of low voltage in insulated conductors, without having to touch the live cable or wire.
