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.
Kilobyte (KB)
The kilobyte, symbolized as KB, represents 1,000 bytes in the decimal system (SI), although in computing, it is commonly approximated as 1,024 bytes. The unit emerged in the 1960s as computer memory and storage expanded and was used for measuring small file sizes, such as text documents and early software. The kilobyte reflects the practical intersection of metric and binary measurements, which led to the introduction of binary-specific units, such as the kibibyte. Kilobytes are still used in some legacy systems and file specifications.
