About these units
Megabit (Mb)
A megabit equals 1,000,000 bits, a standard networking unit used to express data transfer rates. Internet speeds—both broadband and wireless—are typically quoted in megabits per second (Mbps). Because communication systems often care more about transfer rates than storage quantities, the megabit became a natural standard long before modern high-speed networks. The distinction between megabits (Mb) and megabytes (MB) is crucial, as confusing the two leads to misunderstandings about download times. Megabits remain central to evaluating network performance, streaming quality, and bandwidth provisioning.
Petabyte (PB)
A petabyte is 1 quadrillion bytes in decimal (10¹⁵) or 1,125,899,906,842,624 bytes in binary (2⁵⁰). At this size, storage enters the realm of massive data infrastructures: internet archive collections, large-scale scientific simulations, genomic sequencing databases, machine learning datasets containing billions of records, multinational cloud storage networks. A single PB can store thousands of HD films, millions of e-books, or extensive enterprise backups. Petabytes mark the transition from everyday computing into large-scale data engineering, distributed systems, and global information ecosystems.
