Computer Science Manzoor Do Now Due 250 PM

Differentiate RAM and ROM Computer memory. Random-access memory (or simply  RAM ) is the memory or information storage in a computer that is used to store running programs and data for the programs. Data (information) in the  RAM  can be read and written quickly in any order. Normally, the random access memory is in the form of computer chips. Short for  read-only memory ,  ROM  is a storage medium that is used with  computers  and other electronic devices. As the name indicates, data stored in  ROM may only be read. ... Unlike  RAM  (random access  memory ),  ROM  is non-volatile, which means it keeps its contents regardless of whether or not it has power.
