Why does a computer need both RAM and ROM

The cpu is once again responsible for that.Computers do have both ram and rom.In the field of computer science, what is the fundamental distinction between polymorphism and….The data on the random access memory can be read, written, and erased any number of times.Here, are some important advantages of using ram.

While rom is part of a computer's firmware, ram makes running computer programs and processes possible.If cpu wants to read data only from the ram, then the data access from the cache and the registers is slow in comparison to rom.It will persist as long as there is power to the system.It sends a command to the drive to send the data that it needs over to the ram.When you switch off your device, it automatically free the ram.

Because ram memory, as implemented using semiconductors on modern computers, is volatile — it's loses its contents when turned off.This is known under the name of direct memory access or dma for short.Random access memory random access memory (ram) is volatile primary storage.Ram temporarily stores the data that the cpu must process immediately.Rom can keep all the data even when power has been cut off and the pc is shut down rom stores less data and has less storage capacity than ram the main uses for ram are in cpu cache and primary memory.

Even files related to os saved here.Ram is a volatile memory meaning it cannot retain its contents when the power is disconnected.It is a volatile memory.Find out more about ram what is computer ram?
