Difference between RAM (Random Access Memory) and ROM (Read-Only Memory)
Cover Image of Difference between RAM (Random Access Memory) and ROM (Read-Only Memory) with example
Here are the main differences between RAM (Random Access Memory) and ROM (Read-Only Memory) in a table:
| RAM | ROM | |
|---|---|---|
| Definition | A type of computer memory that can be accessed randomly, allowing the computer to access any part of it directly. | A type of computer memory that is permanently or semi-permanently written with data and cannot be easily rewritten or modified by a computer's user or central processing unit (CPU). |
| Purpose | Used to store data that the computer is currently using or processing. | Used to store data that is essential for the computer to boot up and run its basic functions. |
| Volatility | Volatile (data is lost when the power is turned off) | Non-volatile (data is retained even when the power is turned off) |
| Speed | Typically faster than ROM | Typically slower than RAM |
| Capacity | Typically smaller than ROM | Typically larger than RAM |
| Examples | DDR3, DDR4, SDRAM | BIOS, firmware, CD-ROM, DVD-ROM |
I hope this helps!
