Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Hard disk is fixed disk which has a great capacity of storing date normally calculated in ____
A
Tera bytes
B
Mega bytes
C
Kilo bytes
D
Bytes
Explanation: 

Detailed explanation-1: -More than 2 TB. Currently, the highest capacity HDD is 20 TB. However, an HDD actually has less space than advertised, as the operating system, file system structures and some data redundancy procedures use a portion of that space.

Detailed explanation-2: -Hard Discs are used to store operating systems, software applications and all other files. Typical storage spaces are 250 gigabytes up to 4 terabytes (4, 096 gigabytes).

Detailed explanation-3: -Storage capacity of a disk system= number of recording surfaces * number of tracks per surface * Number of sectors per track * Number of bytes per sector.

Detailed explanation-4: -Hard Drive Capacity. The amount of storage on a hard disk is measured in gigabytes and terabytes. Hard drive capacity is measured by the amount of data users need to store, which is often much greater than the space applications take up. For example, a single video can take up four gigabytes of space.
