Megabyte meaning

In legal practice, a megabyte is a unit of digital information used to state file size, storage capacity and data volumes in contracts, IT and outsourcing agreements, telecoms service levels, electronic disclosure/eDiscovery and data protection work. It is a descriptive technical term, not defined by UK or Irish legislation or case law; its operative meaning is usually set by the relevant contract, protocol or court order. A megabyte is abbreviated MB (not Mb, which denotes a megabit). One byte equals eight bits. In many computing contexts, 1 MB is treated as 1,024 kilobytes (KB) = 1,048,576 bytes. Storage vendors and some telecoms materials use the decimal measure 1 MB = 1,000,000 bytes. To avoid disputes over data caps, pricing or service credits, drafting should specify the unit clearly (for example, using “MiB” for 1,048,576 bytes) or state the exact byte count. Usage and interpretation are broadly consistent across England and Wales, Scotland, Northern Ireland and Ireland, but parties should always clarify whether binary (1,024-based) or decimal (1,000-based) units apply and distinguish MB (megabyte) from Mb (megabit).
