Which DOS FORMAT command is used to create a self-booting diskette?
| ( | A | ) | | FORMAT /B |
 |
| ( | B | ) | | FORMAT /S |
|
| ( | C | ) | | FORMAT /A /E |
|
| ( | D | ) | | FORMAT /BOOT |
|
| ( | E | ) | | FORMAT /OS |
The Correct Answer is: B
The most chosen answer was [ C ] :: [ FORMAT /A /E ]
Explanation:
/S (System) is the attribute that should be used with the FORMAT command to create a self-booting diskette.
The files
- IO.SYS
- MSDOS.SYS
- COMMAND.COM
are copied onto the diskette.

|
| ( | D | ) | | 4e2 |
|
| ( | E | ) | | 2f8 |
The Correct Answer is: E
Explanation:
COM 2 is assigned the the I/O address 2f8.
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.
The I/O address 2e8 is used for which COM port?
| ( | A | ) | | COM5 |
|
| ( | B | ) | | COM4 |
|
| ( | C | ) | | COM3 |
|
| ( | D | ) | | COM2 |
|
| ( | E | ) | | COM1 |
The Correct Answer is: B
Explanation:
COM4 uses I/O addresss 2e8.
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
