RAM stores data temporarily.	RAM stores data permanently.
Ram data can be read, erased and modified	Rom data is readable only.
Ram stores data that CPU needs for current instruction processing.	Rom stores data that needed to bootstrap the computer.
CPU can directly access data stored on RAM.	Data is copied from ROM to RAM so that CPU can access data.
RAM is faster memory.	ROM is slower than RAM.
RAM is more expensive	ROM is cheaper than RAM.
Types of RAM are: 1) DRAM 2) SRAM	Types of ROM are: 1)      PROM 2)      EPROM
