Primary memory is faster to access because it is wired directly to the processor. It is used by the system to perform operations while programs are running. Examples are cache, RAM, and ROM.Secondary memory is usually somewhat slower and is used for permanent storage of information. Examples are hard disks, floppy disks, CDs, DVDs, flash memory, etc.

∙ 12y ago- Cache memory is usually "On Die" which means it is in the processor chip, which allows it to 'talk' with the processor direct at a much higher speed than standard RAM.

- cache is a small chip, that's usually placed inside the CPU or sometimes its right next to it and is responsible for providing direct access to the commonly used programs, rather than going back to the hard disk and ram again and again
so
cache makes it more fast than RAM, you know!!!

What is main memory in computer architecture?
main memory is RAM.The words Memory,Buffer,Cache are all refers Ram. Which is Nearly 11,000 times faster than secondary memory (Hard Disk) in Random Access.
Is cache memory is the main memory of cmputer system?
NO...The cache is a smaller, faster memory which stores copies of the data from the most frequently used main memory locations. As long as most memory accesses are cached memory locations, the average latency of memory accesses will be closer to the cache latency than to the latency of main memory.Thus Cache memory is not main memory of computer system.--- form Wiki
Cache memory and register memory?
Register memory are smaller in size than cache memory and registers are faster than cache..Cache memory store the frequently used data from main memory..
What is a cache?
Answer:- The Cache memory is placed between the CPU and the main memory. It is a fast speed memory and is expensive and faster than the main memory. Cache memory is used to store the frequently accessed data of main memory. The instructions that are frequently used by the CPU are stored in the cache memory. It is used to reduce the average access time for address, instructions or data, which are normally stored in the main memory. Cache memory increases the operating speed of the system. But is much costlier than main memory. From economic considerations, the capacity of the cache memory is much less as compared to main memory..
How does virtual memory differ from main memory and secondary memory?
The computer uses microchips for primary and secondary memory. Virtual memory uses a portion of the computers hard drive. The former have faster access times than the latter.
The more memory your computer has the faster it goes?
Generally speaking, yes. However, the main strength of more RAM is that your computer is faster at multitasking but running a single program will also be faster.
Which is the fastest memory device in a computer?
cash memory
How is cache different from primary memory?
Cache memory is a memory that is used by CPU so that the average time to access the memory is reduced. It is a smaller and faster memory that stores copies of data which is used in frequently accessed main memory locations, On the other hand, Primary memory is the main memory of the computer. The processor can easily access, store and retrieve information from the primary memory. Primary memory has two types, Random access memory and read only memory.
Is cache memory is main or sec memory?
cache memory is neither main memory nor second memory. DDR's are Main memory and Disk is second memory.
What is the purpose of Ram Drive system?
The main purpose of a Ram Drive system to make a computer operate faster. It is a faster type of temporary memory that applications can use instead of RAM.
What is an L2 cache and is 6 MB good?
An L2 cache is a small amount of RAM built directly into the processor. This memory is faster than the main system memory. It is used so that the processor doesn't have to fetch data from main memory as often, and thus making many tasks on the computer, such as video games and editing faster. A 6 MB L2 cache is considered good by today's standards.
Why does the speed of a computer increases as soon as we increase the size of the cache memory?
This would ONLY be true if the computer had been built with insufficient cash memory. Cash memory is faster than RAM and its IO performance is matched to the processing speed of the CPU chip. The cash sits between the CPU and the RAM, pre-fetching the data the CPU will need next. It therefore needs to be large enough to ensure that the processor does not use all the data in the cash before more can be staged in from the RAM. After this adding more cash will not improve performance further. Knowing this many chip manufacturers build in the cash needed for the CUP as part of the chip.
