adatméretet

Adatméret refers to the quantity of data that can be stored or transmitted, typically expressed in units based on powers of two or ten. The most common units are bytes, kilobytes, megabytes, gigabytes, terabytes, and petabytes. A byte, consisting of eight bits, is the basic addressable unit in most computer systems. Subsequent units ordinarily scale by powers of 1024 in binary measurement (kibibytes, mebibytes, etc.) but by powers of 1000 in decimal measurement, leading to occasional confusion in product specifications.

In data storage devices such as hard drives, solid-state drives, and memory cards, advertised capacity often uses decimal scaling, whereas operating systems and software may use binary scaling, which can result in apparent discrepancies. For network bandwidth, throughput is usually presented in megabits per second (Mbps) or gigabits per second (Gbps), where one megabit equals one million bits. The difference in units matters for accurate assessment of data transfer speeds, storage consumption, or archival needs.

Computing environments also deploy mechanisms for data compression, encryption, and other transformations that alter the effective adatméret. Modern file systems track allocation in clusters or blocks, and database systems may manage storage in pages, each with a fixed byte size. Understanding adatméret is essential for planning capacity, estimating costs, and evaluating performance in both hardware and software contexts.
