    Differences between RAM and ROM 

    What is ROM? 

    ROM stands for Read-only memory and has a way of storing data in computers and other devices in which can not be easily altered or reprogrammed. ROM is referred to as non-volatile and the contents are kept even after the power is turned off, whereas RAM is known as volatile memory and can be lost when power is turned off. ROM stores the program required to initially boot the computer. It only allows reading. There are many types of ROM, which include PROM, EPROM and EEPROM. A ROM chip is mainly used during the start-up process of a computer, whereas a RAM chip is used mainly in the normal functions of a computer once the operating system has been loaded. A ROM chip can store several megabytes (MB) of data, usually 4 MB or 8 MB per chip. 


     

    What is RAM? 

    RAM is known as Random-access memory and is a form of data storage that can be accessed randomly at any time, in any order and from any physical location, allowing quick access and manipulation. RAM is measured in megabytes and the speed is measured in nanoseconds, which means RAM chips can read data quicker than ROM. RAM allows the computer to read data quickly to run applications. It allows reading and writing. The two main types of RAM are static RAM and dynamic RAM. A RAM chip can store multiple gigabytes (GB) of data, ranging from 1 GB to 256 GB per chip. Writing data to a ROM chip is a much slower process than writing it to a RAM chip.
