Difference Between ROM and RAM :
RAM and ROM are both different types of memories used in computer to make it fast and to enable it to access information stored in the computer.
Details are given below :
ROM :
ROM stands for 'Read Only Memory'. ROM is a non-volatile memory(That require power to maintain the stored information). It is a for of data storage that cannot be easily altered or reprogrammed. It only allows reading. It can not be edited. ROM is a memory that comes within the computer which is pre-written to hold the instructions for booting-up the computer. Data remains stored in ROM even when the power is cut off (When computer is turned off). Means ROM does not require a constant source of power to retain the information. Data is stored permanently on ROM. It is slower than RAM.
There are different types of ROM :
1) PROM (Programmable read-only memory)
2) EPROM (Erasable Programmable read-only memory)
3) EEPROM (Electrically Erasable Programmable read-only memory)
RAM :
RAM stands for 'Random Access Memory'. RAM is a volatile memory(That does not require power to maintain the stored information). It is a form of data storage that can be accessed randomly at any time. RAM allows the computer to read and write the data quickly to run applications. Data stays in RAM as long as the computer is running, and gets deleted as soon as the computer is switched off. Data is stored temporarily in the RAM. It is faster than ROM.
There are two types of RAM :
1) SRAM (Static Random Access Memory)
2) DRAM (Dynamic Random Access Memory)
Please provide feedback about this post.
Thank you.
