About these units
Megabyte (MB)
A megabyte is traditionally 1,048,576 bytes (2²⁰), though storage manufacturers sometimes use the decimal version of 1,000,000 bytes. Throughout the 1980s and 1990s, megabytes represented substantial storage: early PCs had 256 kB or 512 kB of RAM, and hard drives with 10–40 MB were considered spacious. Software developers worked within tight memory budgets, optimizing every byte. Megabytes remain relevant today for file sizes such as images, audio files, small binaries, and executable programs. They mark a transitional era when computing moved from kilobytes to the far larger storage capacities we now expect.
Gigabit (Gb)
A gigabit is 1,000,000,000 bits, commonly used to describe modern network speeds, such as 1 Gbps Ethernet, fiber-optic connections, and high-speed wireless systems. Gigabit connections revolutionized both home and enterprise computing by enabling rapid file transfers, cloud computing, and high-definition streaming. As speeds continue to increase—10, 40, 100 Gbps and beyond—the gigabit becomes a foundational stepping stone in the evolution of networking capability. The Gb illustrates how rapidly communication technology has scaled compared to physical storage.
