What is faster than RAM?
Cache memory operates between 10 to 100 times faster than RAM, requiring only a few nanoseconds to respond to a CPU request. The name of the actual hardware that is used for cache memory is high-speed static random access memory (SRAM).
What is the capacity of ROM?
ROM chips can only store several megabytes (MB) of data, usually amounting to between 4 and 8 MB per ROM chip. RAM chips can store multiple gigabytes (GB); this storage often ranges from 1 to 265 GB per RAM chip. 1 GB is considered to be the equivalent of 1000 MBs.
Does RAM mean storage?
The two components that 'memory' & 'storage' refer to are RAM & the hard drive. The memory is known as RAM. It is is a part of your computer that it uses while it's powered on. Your computer stores everything that it's thinking about in RAM.

What is cache size?
The "size" of the cache is the amount of main memory data it can hold. This size can be calculated as the number of bytes stored in each data block times the number of blocks stored in the cache.
What is the fastest memory?
Cache memory is the fastest system memory, required to keep up with the CPU as it fetches and executes instructions. The data most frequently used by the CPU is stored in cache memory. The fastest portion of the CPU cache is the register file, which contains multiple registers.
Is ROM cache memory?
A ROM is a storage device that holds vital instructions or program data needed to start or boot a computer. It's a non-volatile memory, which means the data it stores is safe even if the power is turned off or the machine is turned off.
