ROM (read only memory): It is the part of memory in which the data or the software related to the hardware is stored which is not to be changed frequently..
Athought the EPROM and EEPROM available now in the market have the ability to be changed easily..
RAM (Random Access Memory): It is the part of memory in which the data can be accesed fast and at random and the continuous movement of the storage is not necessary. like CD and dvds.. it is fast but the volatile since the data stored in it is erased after the system is powered off.
Cache memory: It is the part of memory in which the data from different intermediate calculations or processes is stored where the original data is expensive to fetch...

ROM, on the other hand, stores data that rarely changes, since changing the data would involve replacing the ROM medium. Examples of ROM include the BIOS ROM chip on your motherboard, (though now you will likely see BIOS Flash chips instead) CD-ROM, and CD-R.

ROM, or read only memory. In its pure form, ROM is the data that is permanently written to a chip, that there is no way of overwriting.

∙ 11y agoRead Only Memory (ROM):
Another important part of main memory is Read Only Memory (ROM). Instructions can only be read from ROM. Instructions once written on ROM chip cannot be changed. It is a permanent or non-volatile memory of a computer, i.e. the contents of this type of memory are not lost when the computer is turned off. As soon as the computer is turned on, a program that resides in ROM automatically makes the computer ready for use. ROM is a semiconductor memory generally programmed by the manufacturer.
Random access memory (RAM):
RAM is that part of main memory in which data and instructions are held temporarily. RAM provides a working area to the user to enter and process data. In RAM each data element has its own address (location). Any data element can be read easily and quickly by using that address. It is also called as Read-And-Write Memory (RAM) since the computer can store or write data at any selected location (address) and can retrieve or read data when needed. It is a temporary memory of a computer used to store data and instructions when the computer is on. Everything that is stored in RAM is lost when the computer is turned off. For this reason, it is also called volatile memory. Large RAM sizes provide larger data that a computer can hold and process. Additional RAM chips can be installed in a computer simply by plugging them on motherboard. This increases the storage capacity of RAM of a computer.
RAM is a semiconductor memory with no moving part. Data can be accessed from RAM at very high speed very close to the speed of light. A memory chip less than one-fourth the size of a postage stamp can store data more than 500,000 bytes equivalent to the printed matter on a popular daily newspaper.

∙ 6y agoCache memory - is memory 'set aside' for a specific purpose. ROM - is a chip containing fixed instructions to 'kick-start' the computer. ROM retains the instructions when power is off - Cache memory does not.

∙ 7y agoRandom Access Memory (RAM) is the volatile memory that is used when operating a computer. Once the computer is switched off, the RAM is cleared and any unsaved data is lost. Read Only Memory (ROM) is a chip on the motherboard in which the manufacturer has installed code that will boot up the computer when it is switched on. Basically, Cache Memory is where the computer saves or stores part or all of any websites or programmes the user has visited or uses frequently.

RAM is random memory access which means it handles the applications & functioning.

∙ 10y agoROM - is intended as read only - RAM is read/write
ROM retains its memory when the computer is switched off - RAM doesn't

∙ 11y agoThey are all the same type of memory. All three of them are located internally. Rom can be upgraded. Ram cant be removed from the internal computer.

What is the difference between cache-memory and primary-memory?
Cache memory is smaller and quicker, primary memory larger and slower.
What is the difference between cache memory disk cache?
memory cache is on memory RAM, disk Cache is on the hard drive. They make things to get faster. For instance Google Earth use this disk cache to show you offline images.
What is the difference between cache memory and primary memory?
they are both different so stop asking dumb questions
What are the type of cache memory?
There are different type of cache memory: processor cache memory, cache memory ram,1 cache memory l2, cache memory, CPU cache memory, disk cache memory, hard disk cache, cache memory motherboard.
What are the two types of cache memory?
There are different type of cache memory: processor cache memory, cache memory ram,1 cache memory l2, cache memory, CPU cache memory, disk cache memory, hard disk cache, cache memory motherboard.
What is the name of the memory that sits between the processor and the primary memory?
Cache
Difference between cache memory and ram?
Cache memory is a small, high-speed memory located on the CPU chip that temporarily stores frequently accessed data and instructions to speed up processing. RAM (Random Access Memory) is larger, slower memory that provides temporary storage for data and programs currently in use by the computer. Cache memory is faster but smaller in size compared to RAM.
What is it the difference between Random Access and Second-Level-Cache?
the main memory is usually known as RAM.it stores the data & instructions currently needed by CPU but it operates at a very high speed.therefore, the memory should be fast otherwise there will be a speed mismatch between the two& it may led to the wastage of processing time of CPU.to overcome this a very fast memory CACHE MEMORY is placed between the two. so CACHE MEMORY is used to operate at the speed of CPU.it also increases the operating speed.
Is cache memory visible?
No cache memory is not visible.....
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 an area of high speed memory that sits between the processor and the primary memory?
Cache.
What Is an area of highspeed memory tht sits between the processor and primary memory?
Cache
