Conclusion

With volatile memory, the data is lost when the power is turned off. Non-volatile memory does not lose data when computer is switched off. There are two types of memory: RAM (random access memory) * RAM is held on a computer chip * You can write data into RAM and also read data from RAM * RAM is volatile memory * RAM needs power. If the power is switched off, the data in RAM disappear. * RAM holds data and programs. ROM (read only memory) * ROM is held on a computer chip * ROM cannot be altered by the user. * You cannot store your own data on ROM * ROM is used to hold the instruction for starting up the computer. * ROM is non-volatile memory. ?? ?? ?? ??
