ROM - Read Only Memory
ROM is an internal memory in the computer
which is used to store critical information required by the computer
like booting programs. They are prerecorded and are read only.
RAM - Random Access Memory
RAM is another form of internal memory. RAMs are used to store temporary programs that are currently being executed. They come in large sizes of 4GB's and higher. They are accessible and can be changed.

Random-access memory (RAM) refers to a storage technology
that allows you to read and write data as many times as needed. Contrast this to ROM which allows data to be written once after which it permits only reading.
RAM is typically erased when a computer
is shut down, though some RAM chips maintain data indefinitely without electrical power. Technically, RAM devices are not limited to memory chips, and random-access memory as a storage format is not limited to use as work
ing memory. In a broad sense, modern storage devices for long-term or secondary storage, including magnetic media and laser-readable CDs and DVDs, are forms of random-access memory.
Read-only memory (ROM) refers to a storage technology
that allows you to write data only once. After the data has been written, you can read it an unlimited number of times. Contrast this with random-access memory (RAM) that allows you to read and write data as many times as needed.
Originally, the term ROM referred to memory chips. However, with the creation of other stored devices, the term is being used more widely. In particular, CD-ROM is used to distinguish CDs that can only be read and not written too.

What Is the Difference Between RAM and ROM?
By: Dachary Carey
What is the difference between RAM and ROM? While only one letter's difference separates these two acronyms, the components themselves couldn't be more different.
What is RAM?
"RAM" stands for "random access memory." RAM is memory that stores data in a random order, and it can be written to again and again. However, RAM is functional only when electrical current runs through it, so when your computer
is powered down, it can't hold anything in the RAM. That's why your computer
needs different types of memory; with only RAM, you'd never be able to store any data.
What is ROM?
"ROM" stands for "read-only memory." With ROM, you can only access the data stored on it. You can't write new data to ROM, except in a few select situations. You might run into a CD ROM that's got a computer
program installed on it, or other types of ROM that contain data but to which you can't write data. Because ROM cannot be re-written, it's generally used for long-term storage.
What is the difference between RAM and ROM?
RAM, or random access memory, is memory that you can write to again and again. However, every time you turn off your computer
, the memory is erased. ROM is memory that can only be read. You generally can't write to ROM, except in a few select circumstances. However, ROM contains its data even without electricity, so ROM is ideal as good long-term storage.
How are RAM and ROM used?
You'll find both RAM and ROM in your computer
. Your computer
uses RAM to store data that it's using to work
programs load data that they need to use into your computer
's RAM for immediate or short-term access. The more RAM your computer
has, the more data that it can store for short-term access, and the less frequently it has to access long-term storage devices. This reduction i
