What Is The Difference Between Ram And Rom

Rom is a type of non volatile memory meaning that the data will not be lost when power is removed.

Writing data to rom is very slow. A ram chip can store quite a lot of data up to 16 gb. Data remains even after power supply is not present. Both ram and rom have their set of pros and cons.

Ram is a common type of memory found in computers and printers and can go up to a few gigabytes. Rom data is readonly. Ram stands for random access memory. Computer rom a good example of rom is the computer bios which is a prom chip that stores the programming needed to begin the initial computer startup process.

Rom stands for read only memory. Ram allows the computer to read data quickly and efficiently to be able to run applications efficiently whereas rom stores the program required to initially boot the computer and perform diagnostics. Ram data is volatile. On the other hand ram is quite useful than the read only memory but it.

The rom is cheap and can hold data permanently but it has its limitations. Thus the key difference between ram and rom is in the way the data is stored in them. Ram is a type of volatile memory meaning the stored data is lost when powering off. Static ram or sram which stores a bit of data using the state of a six transistor memory cell.

The storage in ram is temporary whereas the storage in rom is permanent. Ram data can be read erased or modified. Data is present till power supply is present. A rom chip stores several mb megabytes of data usually 4 to 8 mb per chip whereas a ram chip can store multiple gb gigabytes of data ranging from 1 to 256 gb per chip.

Read only memory rom is a type of memory where the data has been prerecorded. Ram is random access memory and cannot hold the data without the power whereas rom is a read only memory and can hold the data even without the power. A computer like the human brain needs memory to store required information.
