Static RAM is more expensive and has more capacity for storage than dynamic RAM that has to be refreshed more often, and is thus slower. It is a programmable chip that stores all the most important instructions required to start the system, this process is also known as bootstrap. ROM is non-volatile memory, Data store is not lost when the power is turned off, it is permanent storage device. RAM requires a flow of electricity to retain data (e.g. What is RAM: RAM stands for Random Access Memory. It is an example of nonvolatile memory. Data stored in ROM is retained even after the computer is turned off ie, non-volatile. Please keep reading the post. ROMs are disadvantageous in use since once the firmware is written in the ROM, it cannot be altered for improvements or corrections. RAM is a read and write memory: Normally ROM is read only memory and it can not be overwritten. On the one hand, where the data in RAM can be modified easily, the data in ROM can be hardly or never be modified. Since both of them are used for storing data, many people often get confused between the two. A computer uses two types of storage. It is a hardware in computing device where the operating system , applications & data in current use are kept so they can be quickly reached by the device's Processor . RAM is a form of computer memory that can be read and changed in any order, typically used to store working data and machine code.ROM is a type of non-volatile memory used in computers and other electronic devices. RAM is a type of volatile memory. Sometimes, the contents of a relatively slow ROM chip are copied to read/write memory to allow for shorter access times. For example, ROM stores the instructions for the computer to start up when it is turned on again. 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. For example, ROM stores the instructions for the computer to start up when it is turned on again.
