Gigabyte meaning

A gigabyte is a unit for measuring the size of electronic data, used in legal practice to quantify volumes of material for disclosure/eDisclosure/eDiscovery, data subject access requests, and digital evidence handling. It is commonly abbreviated gb (not Gb, which denotes a gigabit and measures bandwidth; 1 byte = 8 bits). A gigabyte is typically understood in the decimal sense as 1,000,000,000 bytes, though some systems use the binary measure of 1,073,741,824 bytes (often called a gibibyte or GiB). Because this difference can affect scope, transfer times and cost estimates, contracts, disclosure protocols and costs budgets should specify which convention applies. The term is not defined by UK or Irish legislation or case law; it is a descriptive technical measure used across legal contexts. Usage is consistent across England & Wales, Scotland, Northern Ireland and Ireland. Practical significance: gigabytes determine hosting and processing charges in vendor agreements, inform proportionality assessments, guide search and review planning, and feature in forensic imaging and chain‑of‑custody records.
