What is the difference between cache memories, Ram and Rom?
Hello TopUniverse, Random Access Memory is a form of memory that can be read without having to begin at the first address, then the second address, then the third, and so on. This is a carryover from when most memory was Serial Access, such as magnetic tape, paper tape, or punched cards. The on-board memory computers use for temporary storage is Random Access Memory, but on chips, instead of a hard disc drive. Read Only Memory is exactly what the name implies, it can only be read, not written to. A CD-ROM is a form of memory, as is a chip on the motherboard which is used to store instructions for the Central Processor Unit. RAM is your computer’s temporary storage space. RAM is really the computer’s short-term memory. As such, it remembers everything that the computer needs to process the data into information, such as data that has been entered and software instructions, but only when the computer is on. This means that RAM is an example of volatile storage. When the power is off, the
cache – Hardware implements cache as a block of memory for temporary storage of data likely to be used again. It is a relatively small memory. RAM – It is a volatile memory. Means it can hold data until it is receiving electricity. It is a temporary memory and used by computers to hold program instructions during execution. ROM – It is a permanent memory and normally holds the data necessary to run the computers. Mainly the hardware manufacturers utilized this memory to store the necessary information to run the hardware.
