defferent between ram and rom
Answers
Hey there!
1. Well, ROM means Read Only Memory. ROM is a type of non- volatile memory. Data in ROM is permanently written and is not erased when you power off your computer. This type of memory, once written cannot be changed. It can only be read.
2. Whereas RAM means Read Access Memory. Data in RAM is not permanently written. When you power off your computer the data stored in RAM is deleted. This type of memory, once written can be read and as well as can be changed.
3. The various forms of ROM are PROM (Programmable read only memory) , EPROM (erasable programmable read only memory) , EEPROM (electrically erasable programmable read only memory) while the forms of RAM are static RAM and dynamic RAM.
4, i) RAM is used as the main memory for computations, loading programs, operating system.
ii) ROM is used for storing instructions for bootstrap loading the operating system into the main memory RAM.
5. i) RAM chips can read data faster than ROM.
ii) ROM is slower as compared to RAM.
Hope this helps

RAM = 1.Random access memory.
2. Ram is a form of data storage that can be accessed randomly at any time, in any order by CPU.
3. Ram is volatile I. e., it's contents are lost when the device is powered off.
4.It allows reading and writing.
5.ram chips can read data faster than ROM .
ROM =read only memory
2.rom is also a form of data storage that generally stores hardwired instruction (instruction is stored as form of circuit) for the computer to start initinally.
3.it is non volatile that is its contents are retained even when the device is powered off .
4.it only allows reading .
5.Rom is slower as compared to Ram .
