What is volatile memory?

at the most basic level, unaunate memory stores data without power . This type of memory is important for long -term storage of basic information and data; It would be impossible to work if computer users had to reopen everything contained on the hard disk every time they wanted to use a computer. Some of the different types of non -collising memory include reading memory only (ROM), flash memory, hard drives and optical media such as CDS. It cannot be deleted from the chip. Several other types of lean memory share the abbreviation "ROM", but can actually be rewritten. These include deceased programmable ROMs (EPROM), electrically deceiving programmable ROM (EEPROM) and Flash Memory, also sometimes called Flash Roma. Most EPROM forms are erased using UV light that deletes all the data on the chip, while the EEPROM chip data can be deleted and rewritten. Flash memory has evolved from and is similar to Eeprom. They use optical technology unlike most other types of computer storage thatThey are usually based on magnetics. As a result, they are liberated to certain problems that other forms of media, such as data loss caused by the proximity of magnets, face. Optical discs, however, have their own set of problems, including scratches.

products use the benefits using energy memory. Usually they are produced less expensive than volatile memory, data can be stored up to ten years - and sometimes longer - without energy source and allows hardware to be upgraded. This allows developers to adapt to new technologies and helps to avert full hardware upgrades.

While Image Memory is very useful for long -term storage, it does not work well as short -term, immediate memory. Volatile memory, such as dynamic memory with random access (DRAM) and static memory with random access (SRAM), are more suitable for memory to be read and written. This type of memory is generally more expensivethan energy memory, but is also much faster.
