2. I Beam
3. ROM
4. Hypertext Link

Answer 1

Correct Answer - Option 1 : Cache

The correct answer is Cache.

• Cache memory is an extremely fast memory type that serves as a buffer between RAM and the CPU.
• It holds usually requested data and instructions so that they are immediately available to the CPU when needed.
• Cache memory is used to reduce the average time to access data from the Main memory.
• RAM, which stands for random-access memory, which temporarily stores data while the central processing unit (CPU) is doing other tasks.
• With more RAM on the computer, the less the CPU has to read data from the external or secondary memory (storage device), allowing the computer to run faster.
• RAM is fast though it is volatile, which means it will not retain data if there is no power. It is therefore important to save data to the storage device before the system is turned off.
• RAM and Cache memories are both volatile.
