a) DIFFERENCES BETWEEN RAM AND ROM
|
S/N RANDOM ACCESS MEMORY(RAM) |
READ ONLY MEMORY(ROM) |
|
Volatile |
Non-volatile |
|
Content of RAM can be read, changed or added or added |
Content of ROM can only be read but cannot be changed |
|
RAM chips are relatively expensive |
ROM chips are relatively less expensive |
|
RAM stores all the applications and data when the computer is running |
ROM chips are fast |
|
RAM chips are bigger in size |
Storage capacity of ROM installed in a computer is much lesser |
|
Processor can directly access the content of RAM |
ROM usually stores instructions that are required for starting (booting) the computer |
| RAM chips are slow |
ROM chips are smaller in size Content of ROM are usually first transferred to RAM and then accessed by processor. This is done in order to be able to access |
| RAM is often installed with large storage |
ROM content at a faster speed |
