How can you tell that a particular ribbon cable should only be used to connect a floppy drive?

Explanation
A ribbon cable with a twist in it is specifically designed to connect a floppy drive. The twist is necessary because a floppy drive requires a different signal orientation compared to other devices. This twist ensures that the data is transmitted correctly between the floppy drive and the motherboard. Therefore, if a ribbon cable has a twist in it, it is a clear indication that it should only be used to connect a floppy drive.

The system timer commonly uses IRQ 0. IRQ stands for Interrupt Request and it is a mechanism used by devices to request attention from the CPU. IRQ 0 is typically reserved for the system timer, which generates regular interrupts to keep track of time and schedule tasks. This allows the operating system to perform time-sensitive operations and maintain system stability.

What does RAM mean?

Correct Answer
random access memory

Explanation
RAM stands for random access memory. It is a type of computer memory that allows data to be accessed randomly, meaning any byte of memory can be accessed without touching the preceding bytes. This allows for fast and efficient data storage and retrieval. RAM is volatile, meaning it requires a constant flow of electricity to retain data. It is used by the computer to store data that is currently being processed, allowing for quick access and manipulation.

Which of the following is not a type of RAM?

DIMM
SIMM
ROM
SLIP

Correct Answer

A. ROM

Explanation

ROM stands for Read-Only Memory, which is a type of non-volatile memory that stores data permanently. Unlike RAM (Random Access Memory), ROM cannot be written to or modified. It contains firmware or software instructions that are permanently programmed during manufacturing and cannot be changed by the user. DIMM (Dual In-Line Memory Module) and SIMM (Single In-Line Memory Module) are types of RAM, while SLIP is not a type of memory at all.
