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
The most chosen answer was [ C ] :: [ RTS ]
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.
Capacitors are measured in...
| ( | A | ) | | Ohms |
|
| ( | B | ) | | Farads |
|
| ( | C | ) | | Volts |
|
| ( | D | ) | | Spindles |
|
| ( | E | ) | | Fusers |
The Correct Answer is: B
Explanation:
The Farad is the basic unit of measurement for Capacitors.
Of the following DMA Channels, which is most commonly used by the Sound Card?
| ( | A | ) | | DMA0 |
|
| ( | B | ) | | DMA1 |
|
| ( | C | ) | | DMA2 |
|
| ( | D | ) | | DMA3 |
|
| ( | E | ) | | DMA4 |
The Correct Answer is: B
Explanation:
DMA1 is most commonly used for sound cards. This is the channel that has the most conflicts and should be checked first if conflicts arise. Typical conflicts with this channel arise with network cards, SCSI host adapters, and voice modems.
What does ISDN stand for:
| ( | A | ) | | Integrated Services Digital Network |
|
| ( | B | ) | | Internal Services Device Networked |
|
| ( | C | ) | | Input Send Destination Network |
|
| ( | D | ) | | Input System Digital Network |
|
| ( | E | ) | | Internet System Domain Network |
The Correct Answer is: A
Explanation:
ISDN, or Integrated Services Digital Network, is used as a high speed alternative to modems.
Which of the following still holds a charge even after the power to the system has been disconnected?
| ( | A | ) | | Capacitor |
|
| ( | B | ) | | Fuse |
|
| ( | C | ) | | SIMM chip |
|
| ( | D | ) | | CMOS |
|
| ( | E | ) | | CPU |
The Correct Answer is: A
Explanation:
The Capacitor will keep a charge for an amount of time even after all power has been disconnected. A Capacitor holds a charge in the form of an electrostatic field.
