Stack is also known as:

  1. LIFO memory
  2. FIFO memory
  3. LILO memory
  4. Flash memory

Correct answer: 1. LIFO memory

Explanation:

  1. LIFO stands for Last In, First Out, which means that the last element added to the stack is the first one to be removed.
  2. A stack is a data structure that follows the LIFO principle. It is a collection of elements with two main principal operations: push (to add an element to the top) and pop (to remove the element from the top).
  3. FIFO stands for First In, First Out, which is associated with queues, not stacks. Queues remove the first element added before others.
  4. LILO stands for Last In, Last Out, but it is not commonly used in the context of memory or data structures.
  5. Flash memory is a type of non-volatile storage technology that does not relate to the concept of a stack. Flash memory is used in various electronic devices for data storage.

In conclusion, a stack is also known as LIFO memory due to its characteristic of Last In, First Out.
