  4. 7

  5. 8


Correct Option: D
Explanation:

To solve this question, the user needs to know about the Interrupt Request (IRQ) system and how it applies to the LPT1 (Line Print Terminal 1) port.

LPT1 is a parallel port commonly used for printers and other similar devices. In terms of IRQ, it typically uses IRQ7.

Now, let's go through each option and explain why it is right or wrong:

A. 1: This option is incorrect. IRQ1 is typically used for the keyboard controller.

B. 4: This option is incorrect. IRQ4 is typically used for the serial port COM1.

C. 5: This option is incorrect. IRQ5 is typically used for the sound card.

D. 7: This option is correct. LPT1 commonly uses IRQ7.

E. 8: This option is incorrect. IRQ8 is typically used for the real-time clock.

Therefore, the answer is: D.

  1. the black wires of both connectors should NOT be next to each other

  2. P8 and P9 don't plug into the system board

  3. the black wires of both connectors should be next to each other

  4. it doesn't matter which way you plug them in, the voltages are the same


Correct Option: C
  1. They are identical except for their shape.

  2. AT supplies use a single P1 power connector while ATX uses P8 and P9.

  3. AT power supplies run on 120V AC current while ATX uses 220V AC

  4. AT supplies use P8 and P9 power connectors while ATX uses a single P1 connector.

  3. word processing, spreadsheets, database, and contact management

  4. read, write, calculate, and display

  5. bits, bytes, words, and OSI


Correct Option: A
  1. it's usually open

  2. system timer

  3. real time clock

  4. keyboard

  5. none of the above


Correct Option: D
