| ( | 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
The most chosen answer was [ A ] :: [ COM, I/O, IRQ ]
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).
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
Of the following DMA Channels which is used by the Floppy Disk Controller?
| ( | A | ) | | DMA2 |
|
| ( | B | ) | | DMA4 |
|
| ( | C | ) | | DMA5 |
|
| ( | D | ) | | DMA6 |
|
| ( | E | ) | | DMA7 |
The Correct Answer is: A
Explanation:
The most common DMA (Direct Memory Access) Channels should be known. The Floppy Disk Controller / Floppy Drive uses channel 2, (DMA2).
Which of the following choices is the type of data transmission used by a modem?
| ( | A | ) | | Multisynchronous |
|
| ( | B | ) | | Asynchronous |
|
| ( | C | ) | | Time-delay transmission |
|
| ( | D | ) | | Synchronous |
|
| ( | E | ) | | Digital |
The Correct Answer is: D
Explanation:
Asynchronous transmission is used by modems to send data intermittently rather than at a steady stream. This allows both parties to transmit data at the same time.

| ( | A | ) | | 3 |
|
| ( | B | ) | | 4 |
|
| ( | C | ) | | 5 |
|
| ( | D | ) | | 9 |
|
| ( | E | ) | | None of the above |
The Correct Answer is: C
Explanation:
Usually, Keyboards come with two types of
connectors. They are:
1.
DIN-5
2.
Mini DIN-6
DIN-5 are used with AT style keyboards. DIN-5 has 5
pins. Mini DIN-6, also known as PS/2 connector has around port with 6 pins, one
of which being a square pin used for alignment.
