Final answer:
PROM (Programmable Read-Only Memory) is not suitable for digital exams because it is a physical memory chip that can only be written to once. Digital exams require an electronic platform or software for easy editing, updating, and grading.
Step-by-step explanation:
PROM stands for Programmable Read-Only Memory and it refers to a type of memory that can only be written to once. It is commonly used in devices like microcontrollers and embedded systems. Since PROM is a physical memory chip, it cannot be directly used for a digital exam where the content needs to be easily editable and updated.
In contrast, for a digital exam, an electronic platform or software is used to create, distribute, and grade the exam. This allows for easy editing and updating of exam questions as well as automated grading. It also provides a more interactive and engaging experience for students.
Therefore, PROM is not suitable for digital exams because of its static nature and limited ability to be updated or modified.
