Question

differentiate between the following: (a) ram and rom (b) volatile and non-volatile memory. (c) sequential access and random access​

Answer 1

Answer:

RAM                                                                         ROM

Definition of RAM is Random Access Memory| Definition of ROM is Read-                                                                                                          only Memory

Random Access Memory (RAM) is expensive when compared to ROM ROM is cheaper when compared to RAM.

The speed of Random Access Memory (RAM) is higher when compared to ROM The speed of Read-only Memory (ROM) is slower when compared to RAM.

Random Access Memory (RAM) has a higher capacity when compared to ROM ROM has a lower capacity compared to RAM

Data in RAM can be modified, erased, or read. Data in ROM can only be read, it cannot be modified or erased.

The data stored in RAM is used by the Central Processing Unit (CPU) to process current instructions The data stored in ROM is used to bootstrap the computer.

Data stored on RAM can be accessed by the Central Processing Unit. If the Central Processing Unit (CPU) needs to access the data on ROM, first the data must be transferred to RAM, and then the Central Processing Unit (CPU) will be able to access the data.

Data of RAM is very volatile, it will exist as long as there is no interruption in power. Data present in Read-Only Memory (ROM) is not volatile, it is permanent. Data will remain unchanged even when there is a disruption in the power supply.
