Chapter Summary
{"Image DocumentName": "Chapter Summary", "Image ImageDescription": "\u2022 Spanning is supported in Windows Vista Ultimate and Windows 7 Professional and higher. Spanning is simply configuring more than one hard drive and making it appear to the operating system as one drive; data fills the first drive than the second drive. \u2022 RAID 0 or disk striping does not provide fault tolerance, but does provide fast efficient use of two or more drives. \u2022 RAID 1 is disk mirroring, and this method does provide fault tolerance by having an exact copy of a drive in case one drive fails. \u2022 RAID 5 is disk striping with parity where parity data is kept on one of the three minimum drives. This parity data can be used to rebuild one drive if one of three or more drives fail. \u2022 File systems in use are FAT16, FAT32, exFAT, and NTFS. FAT32 and exFAT are used for external drives such as flash thumb drives. NTFS is used for internal drives and provides features such as better cluster management, security, compression, and encryption. \u2022 If a drive or computer is to be donated or recycled, erase corporate and personal data from the drive. Delete all data, delete all partitions, and use a drive wiping and overwriting utility. Physically destroy (shred, drill, and degauss or use electromagnetism) the platters if the drive contained extremely sensitive data. \u00a9 2014 Pearson IT Certification", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
