How many devices, a 16 bit SCSI-2 can support?
(this question provided by simulationexams.com)
| ( | A | ) | | 8 |
|
| ( | B | ) | | 16 |
|
| ( | C | ) | | 7 |
|
| ( | D | ) | | 14 |
|
| ( | E | ) | | None of the above |
The Correct Answer is: B
Explanation:
For a 16-bit Wide SCSI, there are 16 possible
SCSI Ids, 0-15. A standard 8-bit SCSI can support only 8 devices (including SCSI
card), the Ids allows are 0-7.
SCSI ID - 0=bootable drive, 7=controller, 1-6=any
other devices
SCSI 3 ultra-wide - 16 devices, 0=bootable drive, 15=controller
You have loaded Windows 3.1 into the primary partition on your computer, and made it the default Operating System. You have formatted one of the logical drives in the Extended partition. Which file system would have been installed?
(this question provided by simulationexams.com)
| ( | A | ) | | FAT16 |
|
| ( | B | ) | | FAT32 |
|
| ( | C | ) | | VFAT |
|
| ( | D | ) | | NTFS |
|
| ( | E | ) | | None of the above |
The Correct Answer is: A
Explanation:
-
DOS natively supports only FAT16.
-
Since Windows 3.1 runs on top of DOS, it will also support only FAT16
file system.
-
FAT32 is supported by Windows 98 and Windows 95 OEM Release 2.
-
Note that Windows NT does not support FAT32. NT supports only FAT16 and
NTFS.
Windows 2000 supports FAT16, FAT32, and NTFS
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.
