Ch 2- Key Terms Flashcards
Solid state drive (SSD)
High-performance storage device that contains no moving parts
Hard disk drive (HDD)
Uses rapidly rotating aluminum or nonmagnetic disks called platters coated with a magnetic material known as ferrous oxide to store and retrieve digital information in any order rather than only being accessible sequentially, as in the case of data on a tape
USB drive
External plug-and-play storage device that is plugged into a computer’s USB port and recognized by the computer as a removable drive and assigned a drive letter
Tape
Storage device for saving data by using digital recordings on magnetic tape
Advanced technology attachment (ATA)
Disk drive implementation that integrates the drive and the controller
Fibre Channel (FC)
Technology used to transmit data between computers at data rates up to 10 Gbps
Serial ATA (SATA)
Used to connect host bus adapters to mass storage devices
Serial attached SCSI (SAS)
Data transfer technology that was designed to replace SCSI and to transfer data to and from storage devices
Integrated drive electronics (IDE)
Integrates the controller and the hard drive, allowing the manufacturer to use proprietary communication and storage methods without any compatibility risks for connecting directly to the motherboard
Small computer system interface (SCSI)
Set of standard electronic interfaces accredited by the American National Standard Institute (ANSI) for connecting and transferring data between computers and storage devices
Hierarchical storage management (HSM)
Allows for automatically moving data among four different tiers of storage
Redundant Array of Independent Disks (RAID)
Storage technology that combines multiple hard disk drives into a single logical unit so that the data can be distributed across the hard disk drives for both improved performance and increased security according to their various RAID levels
Unix file system (UFS)
Primary file system for Unix and Unix-based operating systems that uses a hierarchical file system structure where the highest level of the directory is called the root (/, pronounced “slash”) and all other directories span from that root
Extended file system (EXT)
First file system created specifically for Linux where the metadata and file structure is based on the Unix file system
New technology file system (NTFS)
Proprietary file system developed by Microsoft to support the Windows operating systems; it was originally derived from a joint effort with IBM to provide a common OS called OS2, which used the HPFS or High Performance File
