Megabyte (MB)
The megabyte, symbolized as MB, is equal to 1,000,000 bytes in the decimal (SI) system, although in computing, it is often regarded as 1,048,576 bytes (1,024 KB). The term emerged in the 1960s as computers and storage capacity increased, making kilobytes insufficient for describing larger files. Megabytes are used for text, images, and small software applications, providing a human-readable scale for digital data capacity while bridging metric and binary conventions.
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.
