A Correct answer
Explanation

PROM (Programmable Read-Only Memory) can be programmed by the user exactly once using a PROM programmer. During programming, fuses are blown to create the desired pattern. Once programmed, it cannot be reprogrammed - this is why it's called 'one-time programmable'.

Multiple choice

What is the process of converting analogue materials into a digital format called?

  1. CD-ROM

  2. Electronic media

  3. Born-digital

  4. Digital reformatting

  5. Electronic book
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Digital reformatting is the process of converting analogue materials into a digital format as a surrogate of the original. The digital surrogates perform a preservation function by reducing or eliminating the use of the original. Digital reformatting is guided by established best practices to ensure that materials are being converted at the highest quality.

Multiple choice

A pointer is _____.

  1. the address of a variable

  2. an indication of the variable to be accessed next

  3. a variable for storing addresses

  4. the data type of an address variable
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

A pointer is a variable that stores memory addresses. Option C correctly defines a pointer as 'a variable for storing addresses.' Pointers allow you to indirectly access and manipulate memory locations. Option A is incomplete - while pointers contain addresses, they are themselves variables. Option B describes program flow. Option D describes a pointer's type, not what a pointer is.
