Random Access Memory (RAM) is the memory in a computer that is used to store computer programs while they are running and any information the programs need to do their job. Information in the RAM can be read and written quickly in any order. Usually, the RAM is cleared every time the computer is turned off. It is known as 'volatile memory'.
Cache memory is a more expensive memory much faster than regular memory. It is used as a buffer between main memory and the CPU so that repeated access to the same memory address will actually reference t a copy of the information if it is still stored cache memory. This speeds up the way applications work.
This is different than cache storage as when internet Explorer uses a cache to store recently visited web page information so that a subsequent access to the web page will retrieve the data from cache instead of fetching it through the internet. This makes it much faster when you browse the Internet as it doesn't have to fetch every single file every time.
ROM is a memory which is not cleared when power is turned off. The BIOS ROM permanently stores essential system instructions (BIOS). The data held on ROM can be read but not changed. This is done during manufacturing. ROM is non volatile, meaning that the data stored on it will not be lost when the computer is switched off.

How many levels of cache memory?
there are twothree.instruction cachedata cacheconsolidated cache
Which is faster among ram or cache or CD rom or registers?
cache
Which area of the computer holds the data and instruction that are about to be used by the central processing unit?
MAIN MEMORY
Why are RAM and ROM software?
ram is random access memory and ROM is read only memory
The definition for ROM ram eprom eeprom?
ROM: Read Only Memory, Memory that can only be read, it cannot be rewritten. RAM: Random Access Memory, it's a kind of memory that can be read and rewritten many times, it loses its information when it loses power.
What type of memory is mostly closely connected to the CPU?
In this instance, you likely mean cache memory, though you could mean RAM, particularly DRAM. Cache memory, like the L1, L2, and L3 processor cache, helps to speed up operations between the CPU and RAM.
What is the expanded form of RAM and ROM?
RAM is random access memory and ROM is read-only memory.
What is do the acronyms RAM and Rom mean?
RAM - Random Access Memory ROM - Read Only Memory
Is Cache memory a form of ROM?
No. It's a kind of RAM integrated into your processor. The cache memory is usually small and is used to store data that is being used by the processor because accessing the main RAM directly will be slower. In multiple-processor systems, a problem called cache incoherence can occur when two or more processors access the same region, modifies the data in different ways and not immediately writing back the data to the main RAM. It will cause two different versions of the same region existing simultaneously, causing problems. That is why mutexes or other locks should be used when accessing shared memory.
What allows faster access- RAM ROM or virtual memory a. ROM b. Virtual Memory c. RAM d. All of the above?
rom
Which of the following can be added by the expansion card a cache b register c RAM d ROM?
Cache
Which memory is in built in CPU?
if you mean processor then cache memory if you mean computer then ROM
