Correct Option: D

Which IRQ does COM1 commonly use?
hardware

  1. 3

  2. 4

  3. 6

  4. 7

  5. 14

Show answer
Correct Option: B
Explanation:

To solve this question, the user needs to have knowledge about computer hardware and specifically about the IRQ (Interrupt Request) system.

The IRQ system is used by devices to communicate with the CPU (Central Processing Unit) and request its attention. Each device is assigned a specific IRQ number to ensure proper communication and coordination.

COM1 is a standard serial port used for connecting peripherals such as modems or serial mice. In the IRQ system, COM1 commonly uses IRQ 4.

Let's go through each option and explain why it is right or wrong:

A. 3: This option is incorrect because COM1 commonly uses IRQ 4, not IRQ 3.

B. 4: This option is correct. COM1 commonly uses IRQ 4.

C. 6: This option is incorrect because COM1 commonly uses IRQ 4, not IRQ 6.

D. 7: This option is incorrect because COM1 commonly uses IRQ 4, not IRQ 7.

E. 14: This option is incorrect because COM1 commonly uses IRQ 4, not IRQ 14.

The Answer is: B

Which of the following retains the information it's storing when the power to the system is turned off?
hardware

  1. CPU

  2. ROM

  3. RAM

  4. DRAM

  5. DIMM

Show answer
Correct Option: B
Explanation:

To solve this question, the user needs to know the differences between the types of computer memory.

A. CPU (Central Processing Unit) is not a type of memory, it is a processing unit that performs most of the processing inside a computer.

B. ROM (Read-Only Memory) is a type of non-volatile memory that retains its data even when the power is turned off. It is used to store firmware, BIOS, and other permanent system data.

C. RAM (Random Access Memory) is a type of volatile memory that does not retain its data when the power is turned off. It is used to temporarily store data while the computer is running.

D. DRAM (Dynamic Random Access Memory) is a type of volatile memory that requires constant refreshing to retain its data. It is used as the main memory in most computers.

E. DIMM (Dual In-Line Memory Module) is not a type of memory, it is a form factor for RAM modules.

Therefore, the correct answer is B. ROM.

Which of the following is NOT a type of RAM?

hardware

  1. SIMM

  2. DIMM

  4. SLIPP

Show answer
Correct Option: C

AI Explanation

To answer this question, you need to understand the different types of RAM and identify which option is not a type of RAM.

Let's go through each option to understand why it is correct or incorrect:

Option A) SIMM - This option is a type of RAM. SIMM stands for Single Inline Memory Module and was a common type of memory module used in older computers.

Option B) DIMM - This option is also a type of RAM. DIMM stands for Dual Inline Memory Module and is the most common type of memory module used in modern computers.

Option C) ROM - This option is NOT a type of RAM. ROM stands for Read-Only Memory and is a type of non-volatile memory that stores permanent data and instructions. Unlike RAM, ROM cannot be written to or modified.

Option D) SLIPP - This option is not a recognized type of RAM. It is likely a made-up term or a typo.

The correct answer is C) ROM. This option is not a type of RAM because ROM is a separate category of memory that serves a different purpose.
