RAM & Hard Disk
Random-access memory, RAM for short is a computer data storage. The two main modern RAMS are Static RAM and dynamic RAM. Static random-access memory is a type of semiconductor memory that uses bistable circuits to store each bit. Dynamic RAM s a type of random access memory that stores each bit of data in a separate capacitor within an integrated circuit. The capacitor can be either charged or discharged; these two states are taken to represent the two values of a bit, conventionally called 0 and 1.
A hard disk is av magnetic disk on which you can store computer data. The term hard is used to distinguish it from a soft, or floppy, disk. Hard disks hold more data and are faster than floppy disks. A hard disk, for example, can store anywhere from 10 to more than 100 gigabytes, whereas most floppies have a maximum storage capacity of 1.4 megabytes.
