What is cache memory?

 As we all know about ROM and RAM 😎. And there is also a type of memory that is called Cache memory. 😎

Frankly writing that when I was also unaware of that memory 😉, I used to clear that memory from the apps of my phone. 

But that was a mistake. How?🤔

Cache Memory is something the fastest among all the memories that have been mentioned above(RAM and ROM)👍.  Yes, you read it right😌, Cache Memory is the fastest and the most expensive💰 among them.

But, the question is, why only cache memory, why is it important, and how it is so fast?🤔

The answer to the first two questions is that Cache memory is the fastest and in today's world, speed matters a lot to everyone. Now coming to the third question that how it is so fast. 

The Cache Memory is directly connected to the CPU of any computer😯. CPU first approaches the cache memory and then goes to other ones. When we clear this memory, the CPU has to perform more tasks than usual. Because CPU firstly approaches to the cache memory and if it was unable to find anything there then it goes to ROM. Hence, it takes more time than usual.🤔

So.......

Think before clearing the Cache Memory.......🧑‍💻
