Name the fundamental kinds of memory used in microprocessor systems
There are three fundamental kinds of memory used in microprocessor systems - generallyknown asRAM, ROM, and hybrid. RAM and ROM are-'Read Only Memory' and 'Random Access Memory'. Program may be stored in RAM or ROM - the program doesn't normally change while it executes -when data is stored in the registers and RAM. Of course, if you turn off chip and turn it on again, you have lost all the contents of registers, and RAM.
In a typical computer, as much as possible is in RAM, to give maximum possible flexibility; you have fundamental programmes allowing you to interact with keyboards, discs and the display in ROM and load in as much of the software as probably when you run the programs.
