Gigabyte (GB)
The gigabyte, symbol GB, represents 1,000,000,000 bytes in decimal, though in binary it is often approximated as 1,073,741,824 bytes (1,024 MiB). The unit was introduced in the 1980s as personal computers and hard drives increased capacity. Gigabytes measure larger data volumes, including software, multimedia, and storage devices, and became the standard for consumer storage, networking, and cloud computing as a scale between megabytes and terabytes.
Terabyte (TB)
The terabyte, symbolized as TB, equals 1,000,000,000,000 bytes in decimal (approximately 1,024 GB in binary). It emerged in the 1990s as storage systems, databases, and servers experienced exponential growth. Terabytes are used to measure hard drives, enterprise storage, data centers, and cloud services. With the rise of big data, video streaming, and high-resolution imaging, the terabyte has become a practical unit for both consumers and professionals. Its adoption enables comprehension of massive digital storage in manageable terms.
