Detailed explanation-1: -Computer storage and memory is often measured in megabytes (MB) and gigabytes (GB). A medium-sized novel contains about 1 MB of information. 1 MB is 1, 024 kilobytes, or 1, 048, 576 (1024x1024) bytes, not one million bytes. Similarly, one 1 GB is 1, 024 MB, or 1, 073, 741, 824 (1024x1024x1024) bytes.
Detailed explanation-2: -A byte is a unit of measurement of the size of information on a computer or other electronic device. A single byte is usually eight bits. Some early computers used six bits for each byte. Bits are the smallest unit of storage on a computer, a single on/off value.
Detailed explanation-3: -The basic volume calculation is length × width × height. It doesn’t matter which side you call what-the important thing is that all three are multiplied together. As an example: A box that is 20cm width, 15cm long and 10 cm height has a volume of: 20 × 15 × 10 = 3000 cm cubed.
Detailed explanation-4: -A terabyte is bigger than a gigabyte. A terabyte is equal to 1, 024 gigabytes (GB), which itself is equal to 1, 024 megabytes (MB), while a megabyte is equivalent to 1, 024 kilobytes. All storage measuring units–kilobyte, megabyte, terabyte, gigabyte, petabyte, exabyte and so on–are multiples of a byte.
Detailed explanation-5: -A yottabyte is the largest unit approved as a standard size by the International System of Units (SI). The yottabyte is about 1 septillion bytes–or, as an integer, 1, 000, 000, 000, 000, 000, 000, 000, 000 bytes.
