The most common unit of storage in computer is called a byte which is equal to 8 bits. A computer word, like a byte, is a group of fixed number of bits processed as a unit, which varies from computer to computer but is fixed for each computer. â¢ Is a computer data storage on a medium or a device that is not under the control of a processing unit. Since your computer uses a binary system as mentioned above, you may notice a discrepancy between your hard drive's published capacity and the capacity acknowledged by your computer. The methods are specific to the type of data, as outlined below. 3. A memory area used for the temporary storage of data (usually as a step in transferring the data). For example, a hard drive that is said to contain 10 GB of storage space using a decimal system is actually capable of storing 10,000,000,000 bytes. 1 0 obj 2 0 obj Can differentiate storage into: " volatile storage: loses contents when power is switched off " non-volatile storage: # Contents persist even when power is switched off.
