1 |
Random Access Memory or RAM 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. |
Read-only memory or ROM is also a form of data storage that can not be easily altered or reprogrammed. Stores instructions that are not necessary for re-booting up to make the computer operate when it is switched off. They are hardwired. |
2 |
A RAM chip does require a constant source of power to retain the information |
A ROM chip does not require a constant source of power to retain the information stored on it |
3 |
RAM allows the computer to read data quickly to run applications. It allows reading and writing. |
ROM stores the program required to initially boot the computer. It only allows reading. |
4 |
RAM is volatile i.e. its contents are lost when the device is powered off. |
It is non-volatile i.e. its contents are retained even when the device is powered off. |
5 |
The two main types of RAM are static RAM and dynamic RAM. |
The types of ROM include PROM, EPROM and EEPROM. |
