RAM (random access memory):
It is the place in a computer where the operating system, application programs, and data in current use are kept so that they can be quickly reached by the computer's processor. RAM is much faster to read from and write to than the other kinds of storage in a computer, the hard disk, floppy disk, and CD-ROM. However, the data in RAM stays there only as long as your computer is running. When you turn the computer off, RAM loses its data. When you turn your computer on again, your operating system and other files are once again loaded into RAM, usually from your hard disk.
RAM can be compared to a person's short-term memory and the hard disk to the long-term memory. The short-term memory focuses on work at hand, but can only keep so many facts in view at one time. If short-term memory fills up, your brain sometimes is able to refresh it from facts stored in long-term memory. A computer also works this way. If RAM fills up, the processor needs to continually go to the hard disk to overlay old data in RAM with new, slowing down the computer's operation. Unlike the hard disk which can become completely full of data so that it won't accept any more, RAM never runs out of memory. It keeps operating, but much more slowly than you may want it to.

ram is random access memory and ROM is read only memory
ROM
the difference is the spelling. R-A-M and R-O-M. they after important because, computer needs it.
RAM - Random Access Memory ROM - Read Only Memory
RAM is random access memory and ROM is read-only memory.
Ram
rom
The BIOS is stored on ROM.
ROM isn't erased when you turn the power off, whereas RAM is.
RAM is a volatile Memory. But ROM is not volatile.
RAM is an acronym for Random Access Memory; ROM is an acronym for Read Only Memory. Both RAM and ROM are random access; that is, each cell in memory is directly accessible. The cells in RAM can be both read from and written to. The cells in ROM can only be read from. The bit pattern in ROM is determined at the time of manufacture or burned when the computer is assembled. Once a ROM has been burned (written), it cannot be changed. Another major difference is that RAM is volatile and ROM is not. This means that RAM does not maintain its bit patterns when the power is turned off, but ROM does.
