is cache memory a form of rom?
319788
No, it is actually a form of RAM. ROM is read only memory, where as RAM is random access memory. Many older computer systems in the 8 bit and 16 bit eras used a ROM chip for the operating system. ... Cache is basically a small but really fast workspace for the CPU, and is many times faster than main system RAM.

RAM is used to store computer programs and data that CPU needs in real time. RAM data is volatile and is erased once computer is switched off. ROM have prerecorded data and it is used to boot computer. RAM data is static and remains in the computer even if computer is switched off.

The term "virtual memory" refers to space allocated on a hard disk where data can be stored for fast access. Cache memory is a small high-speed memory usually Static RAM (SRAM) that contains the most recently accessed pieces of main memory. Virtual memory enlarges the volume of RAM.

The difference in them are that RAM is primary memory and ROM and Hard drive is secondary memory. RAM is also called temporary memory because data it stores data for less time or temporarily while ROM and Hard drive stores permanently although we can delete the data from ROM.

RAM, which stands for random access memory, and ROM, which stands for read-only memory, are both present in your computer. RAM is volatile memory that temporarily stores the files you are working on. ROM is non-volatile memory that permanently stores instructions for your computer.

Cache Memory is a special very high-speed memory. It is used to speed up and synchronizing with high-speed CPU. Cache memory is costlier than main memory or disk memory but economical than CPU registers. ... The cache is a smaller and faster memory which stores copies of the data from frequently used main memory locations.

Cache memory is used to speed program execution and data processing. Main memory holds the programs and data loaded into the computer from even slower storage, like disk or network.

RAM is a type of volatile memory because it will lose its data if the power is turned off. ROM or Read Only Memory is a type of non-volatile memory which means it keeps its data even if the power is turned off. However typically data in ROM cannot be changed.

EPROM can be used for Erasing and reconstructing the contents of ROM. EPROM (erasable programmable read-only memory) is programmable read-only memory (programmable ROM) that can be erased and re-used. Erasure is caused by shining an intense ultraviolet light through a window that is designed into the memory chip.

RAM equals the memory (or memory bar) of the computer, while ROM is the device's internal storage, equaling the hard disk of the computer. ... The bigger the RAM, the more software the phone runs smoothly; While the bigger the ROM, the more data it can store.

RAM stands for Random Access Memory. ROM stands for Read Only Memory.

Difference between RAM and ROM RAM is Random Access Memory, while ROM stands for Read Only Memory. RAM is volatile and is erased when the computer is switched off. ROM is non-volatile and generally cannot be written to. ... The bit is the basic unit for storing data in computer memory 0 means off, 1 means on.

Both cache and RAM are volatile memory. The difference between cache and RAM is that the cache is a fast memory component that stores the frequently used data by the CPU while RAM is a computing device that stores data and programs currently used by the CPU. In brief, the cache is faster and expensive than RAM.

Phone's memory includes RAM and ROM. RAM equals the memory (or memory bar) of the computer, while ROM is the device's internal storage, equaling the hard disk of the computer. The bigger the RAM, the more software the phone runs smoothly; While the bigger the ROM, the more data it can store.

A ROM chip is a non-volatile storage medium, which means it does not require a constant source of power to retain the information stored on it. By contrast, a RAM chip is volatile, which means it loses any information it is holding when the power is turned off.

Flash is erasable and reprogrammable ROM. Flash memory content is retained by the router on power-down or reload. ... RAM contents are lost when the router is powered down or reloaded. NVRAM is non-volatile RAM.

Cache memory is sometimes called CPU (central processing unit) memory because it is typically integrated directly into the CPU chip or placed on a separate chip that has a separate bus interconnect with the CPU.
