What is the difference between ROM and RAM?

do you know what is CPU, ALU, and other short stuffs related to computers? sometimes it really bothers me when people use them to describe computers and i don't understand any thing. i know only that if press on button computer get on and then i can access internet and other stuffs :).

rom stands for read only memory and ram stands for random access memory. the two differ in thier manner of accessing datas. greetings. : )

ROM : Read Only Memory RAM : Random Access Memory we cannot easily change the data in a ROM . we can easily change the data in a RAM . ROM is used where programming is not required . It is programmed once and used as it is . RAM is used where programming is possible . it can be written many number of times .

I forgot the meaning of ROM!...RAM is the random access memory!...That's the only thing i know!..Hope im right!...lolz
