Unlike other types of memory such as RAM or EEPROM, ROM does not require power to maintain its data, making it nonvolatile and permanent.

An interrupt is a signal from a hardware device to the CPU indicating that it requires attention. It can be either asynchronous, meaning it can occur at any time, or synchronous, meaning it occurs at a specific time. Interrupts allow the CPU to handle multiple tasks efficiently by temporarily suspending the current task and switching to a different task that requires attention. Therefore, an interrupt is the correct answer as it perfectly fits the definition given in the question.

A parity bit is a very simple example of an error-detecting code. It is a single bit that is added to a binary code to detect errors during transmission. The parity bit is set to either 0 or 1, depending on the number of 1s in the code. If the number of 1s is even, the parity bit is set to 0, and if the number of 1s is odd, the parity bit is set to 1. During transmission, the receiver can check if the number of 1s in the received code matches the parity bit. If they don't match, an error is detected.

The correct answer is Basic input output system (BIOS). The BIOS is responsible for initializing communication with all hardware devices in a computer system. It is the first software that runs when a computer is powered on and performs a power-on self-test (POST) to check if all hardware components are functioning properly. If a keyboard or mouse is not found during the POST, the BIOS will send a message indicating the absence of these devices.

Electrostatic discharge refers to the sudden and momentary electric current that occurs between two objects at different electrical potentials. This phenomenon typically happens when there is a buildup of static electricity on one object, and it discharges to another object with a lower electrical potential. This discharge can result in a visible spark or shock and can potentially damage electronic components.

Fault isolation refers to the process of identifying and analyzing the cause of an operational failure or fault in order to prevent it from happening again. This involves collecting and analyzing data related to the failure, investigating the underlying factors, and implementing measures to prevent its recurrence. Fault isolation is an essential step in troubleshooting and problem-solving, as it helps to identify the root cause and develop effective solutions to prevent similar failures in the future.

In the troubleshooting process, the step of "Resolving the problem" involves identifying likely causes and eliminating unlikely causes.
