\tDifferenceRAMROMData retentionRAM is a volatile memory which could store the data as long as the power is supplied.ROM is a non-volatile memory which could retain the data even when power is turned off.Working typeData stored in RAM can be retrieved and altered.Data stored in ROM can only be read.UseUsed to store the data that has to be currently processed by CPU temporarily.It stores the instructions required during bootstrap of the computer.SpeedIt is a high-speed memory.It is much slower than the RAM.CPU InteractionThe CPU can access the data stored on it.The CPU can not access the data stored on it unless the data is stored in RAM.Size and CapacityLarge size with higher capacity.Small size with less capacity.Used as/inCPU Cache, Primary memory.Firmware, Micro-controllersAccessibilityThe data stored is easily accessibleThe data stored is not as easily accessible as in RAMCostCostliercheaper than RAM.\t

RAM, which stands for random access memory, and ROM, which stands for read-only memory, are both present in your computer. RAM is volatile memory that temporarily stores the files you are working on. ROM is non-volatile memory that permanently stores instructions for your computer.
