Electrical Engineering XYZ MCQs
Queue is also known as:
- LIFO memory
- FIFO memory
- LILO memory
- Flash memory
Correct answer: 2. FIFO memory
Explanation: Queue is a data structure that follows the First-In-First-Out (FIFO) principle. In a queue, the first element added is the first one to be removed. This is similar to a queue in a real-world scenario, where the first person standing in line is the first one to be served. The term “FIFO memory” refers to a memory structure that operates on the FIFO principle, and it is commonly associated with queues. Therefore, the correct choice is “FIFO memory.”
The other options do not accurately describe a queue:
- LIFO (Last-In-First-Out) memory is associated with stacks, not queues. In a stack, the last element added is the first one to be removed.
- LILO (Last-In-Last-Out) is not a standard term used in the context of memory structures or data structures.
- Flash memory is a type of non-volatile computer storage that can be electrically erased and reprogrammed. It is not synonymous with a queue or any specific data structure.
