Difference between RAM and ROM

RAM (Random Access Memory)
         
RAM is also a part of computer local memory where the computer stores the data and instructions it receives from input devices and also stores the results after a calculation.
         RAM is a Temporary memory or Volatile memory. It means when the computer is switched off all the information will be lost. RAM requires very less time to retrieve data and is considered to be the fastest memory.

ROM( Read Only Memory)
         ROM stores a set of instructions permanently, which instructs the computer, how to work. Some variation of this type of memory is PROM known as Programmable Read Only Memory where the flexibility of data alteration is possible.
          The basic difference between ROM and RAM is ROM is permanent memory and RAM is temporary memory. The speed of retrieving data is slow in ROM as compared to RAM.
