(a)  

It is a type of RAM which allows you

to stores each bit of data in a separate

capacitor within a specific integrated circuit.

(a)  

is a standard computer

memory of the many modern desktop

computers

(a)  

a non-

volatile data storage device. Non-volatile

refers to storage devices that maintain

stored data when turned off

(a)  

is the hardware component

that stores all of your digital content. Your

documents, pictures, music, videos,

programs, application preferences, and

operating system represent digital content

stored on a hard drive

processor chip, it consumes more power and

generates a significant amount of heat. However,

since it has its own memory
