Using the Autoexec.bat file, how would you load device drivers into Upper Memory?
| ( | A | ) | | UpperMem= |
 |
| ( | B | ) | | LoadHigh= |
|
| ( | C | ) | | EMM= |
|
| ( | D | ) | | HighLoad= |
|
| ( | E | ) | | Autoexec= |
The Correct Answer is: B
The most chosen answer was [ C ] :: [ EMM= ]
Explanation:
Starting a line with "LoadHigh=" followed by the location and name of the driver will load that device into Upper Memory the next time the Autoexec.bat file is run.
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.
ISDN uses which of the following technologies?
| ( | A | ) | | Digital and analog |

|
| ( | C | ) | | Only digital |
|
| ( | D | ) | | Laser diode |
|
| ( | E | ) | | None of the above |
The Correct Answer is: C
Explanation:
ISDN uses only digital signals to transfer data packets.
What 3 things must be configured in the Operating System in order to use an internal modem?
| ( | A | ) | | COM, I/O, IRQ |
|
| ( | B | ) | | DMA Channel, IRQ, I/O |
|
| ( | C | ) | | IRQ, I/O |
|
| ( | D | ) | | DMA Channel, I/O |
|
| ( | E | ) | | COM, DMA Channel, IRQ |
The Correct Answer is: A
Explanation:
The 3 things that must be configured for an internal modem to work are the COM port, I/O address, and IRQ (Interupt Request).
Which of the following terms is used to explain the process of two modem establishing communication with each other?
| ( | A | ) | | Sharing |
|

|
| ( | C | ) | | Negotiating |
|
| ( | D | ) | | Duplexing |
|
| ( | E | ) | | Handshaking |
The Correct Answer is: E
Explanation:
Handshaking is used to describe the process of modems trying to connect with each other.
