A disk compression software utility increases the amount of information that can be stored on a hard disk drive of given size. Unlike a file compression utility, which compresses only specified files—and which requires the user to designate the files to be compressed—an on-the-fly disk compression utility works automatically through resident software without the user needing to be aware of ...
In data storage, disk mirroring is the replication of logical disk volumes onto separate physical hard disks in real time to ensure continuous availability. It is most commonly used in RAID 1 . A mirrored volume is a complete logical representation of separate volume copies.
Windows 11 SE was announced on November 9, 2021, as an edition exclusively for low-end devices sold in the education market; it is intended as a successor to Windows 10 S, and also competes primarily with ChromeOS. It is designed to be managed via Microsoft Intune. Based on feedback from educators, Windows 11 SE has multiple UI differences and ...
A compression ratio of at least 50:1 is needed to get 1080i video into a 20 Mbit/s MPEG transport stream. [1] Uses
The maximum NTFS volume size implemented in Windows XP Professional is 2 32 − 1 clusters, partly due to partition table limitations. For example, using 64 KB clusters, the maximum size Windows XP NTFS volume is 256 TB minus 64 KB. Using the default cluster size of 4 KB, the maximum NTFS volume size is 16 TB minus 4 KB.
exFAT is a file system introduced with Windows Embedded CE 6.0 in November 2006 and brought to the Windows NT family with Vista Service Pack 1 and Windows XP Service Pack 3 (or separate installation of Windows XP Update KB955704). It is loosely based on the File Allocation Table architecture, but incompatible, proprietary and protected by patents.
Floppy disk size is often referred to in inches, even in countries using metric and though the size is defined in metric. The ANSI specification of 3½-inch disks is entitled in part "90 mm (3.5-inch)" though 90 mm is closer to 3.54 inches. [50] Formatted capacities are generally set in terms of kilobytes and megabytes.
This discrepancy causes confusion, as a disk with an advertised capacity of, for example, 400 GB (meaning 400 000 000 000 bytes, equal to 372 GiB) might be reported by the operating system as "372 GB". For RAM, the JEDEC memory standards use IEEE 100 nomenclature which quote the gigabyte as 1 073 741 824 bytes (2 30 bytes). [11]
