Which hardware component stores instructions for critical system activities?

Rationale

Read-only memory (ROM) stores instructions for critical system activities.

ROM is a type of non-volatile memory that retains its contents even when the power is turned off, making it essential for storing firmware and critical system instructions necessary for booting and hardware initialization.

A (Random-access memory (RAM)) YOUR ANSWER

RAM is a volatile memory type that temporarily stores data and instructions for the CPU while the system is running. However, it loses all stored information when power is lost, making it unsuitable for storing critical system activities that must persist across reboots.

B (Read-only memory (ROM)) CORRECT

ROM is specifically designed to hold critical system instructions permanently. It contains the firmware necessary for the computer's basic functions, such as booting the operating system and performing hardware checks, ensuring that these instructions are always available on startup.

C (Central processing unit (CPU)) YOUR ANSWER

The CPU is the main processing unit of a computer that executes instructions from RAM. While it performs critical computational tasks, it does not store instructions permanently; it relies on RAM and ROM for instruction retrieval.

D (Graphics processing unit (GPU)) YOUR ANSWER

The GPU is specialized hardware designed for rendering images and managing graphics operations. Although it can process complex graphical instructions, it does not store critical system activities or instructions necessary for the overall functioning of the computer system.

Conclusion

Read-only memory (ROM) is the key hardware component responsible for storing essential instructions for critical system activities because it retains its data regardless of power status. In contrast, RAM, CPU, and GPU serve different roles in the computing process and do not provide the same permanent storage of vital system instructions. This distinction is crucial for understanding how computers boot and operate reliably.
