Terabyte (TB)
Definition: A terabyte (symbol: TB) is a multiple of the unit byte for digital information. The prefix tera means 10^12 in the SI. Therefore, one terabyte is one trillion bytes. In the binary system, 1 TB is often defined as 1,099,511,627,776 bytes.
History/origin: The terabyte was introduced as part of the metric system in 1795. It was originally defined as 1,000,000,000,000 bytes. In the binary system, it is defined as 1,099,511,627,776 bytes.
Current use: The terabyte is commonly used to measure the capacity of large storage devices, such as hard drives, SSDs, and cloud storage. It is also used to measure the size of large files and databases.
Gigabyte (GB)
Definition: A gigabyte (symbol: GB) is a multiple of the unit byte for digital information. The prefix giga means 10^9 in the SI. Therefore, one gigabyte is one billion bytes. In the binary system, 1 GB is often defined as 1,073,741,824 bytes.
History/origin: The gigabyte was introduced as part of the metric system in 1795. It was originally defined as 1,000,000,000 bytes. In the binary system, it is defined as 1,073,741,824 bytes.
Current use: The gigabyte is commonly used to measure the capacity of computer storage, such as hard drives, SSDs, and USB flash drives. They are also used to measure the size of large files, like high-definition videos, video games, and software applications.
