A+ Second Edition Genetic Computer School Lesson 5 Storage Devices

A+ Second Edition Genetic Computer School Overview  Integrated Drive Electronics (IDE)  Solid-state Drives  RAID  Floppy Drivers  CD-ROM  DVD  Tape Drives  Some Interfaces

A+ Second Edition Genetic Computer School Integrated Drive Electronics (IDE)  It is also known as ATA  It refers to any drive that has a built in controller

A+ Second Edition Genetic Computer School ATA specifications  The 40 PIN connector on the drive  Timing of signals  Allow for two devices to be connected to the same data cable that will interface with the system bus.  The Master Slave concept when two drives are attached to one cable.

A+ Second Edition Genetic Computer School Solid-state Drives Aim to  Solve the problems associated with hard drive mechanism by replacing them with memory chips  Offer low power consumption and heat production  Get faster startup  Get quick seek times without moving parts

A+ Second Edition Genetic Computer School Redundant Array of Inexpensive Drives (RAID) Hard drives can be configured in a RAID configuration that is used for a variety of purposes including data recovery and increased read/write performance depending on the level of RAID employed.

A+ Second Edition Genetic Computer School RAID Levels  RAID Level 0  RAID Level 1  RAID Level 2  RAID Level 3  RAID Level 4  RAID Level 5

A+ Second Edition Genetic Computer School Floppy Drivers  The installation of a floppy drive  Disk Types and Sizes (Data Storage)

A+ Second Edition Genetic Computer School CD-ROM (Compact Disk Read Only Memory) It is a drive which reads aluminum- coated round plastic discs, however does not write to the discs. Newer CD-ROM drives have the capability to record data. CDFS (Compact Disk File System) is the type of filing system CD-ROMs use to store information.

A+ Second Edition Genetic Computer School Types of CD Recorders There are two main types  CD-R (Recordable)  CD-R/RW (Recordable/Rewritable)

A+ Second Edition Genetic Computer School DVDs  Digital video disc or digital versatile disc (once)  The next generation of optical disc storage technology (now) Physical formats  DVD-ROM  DVD-R Application formats  DVD-Video  DVD-Audio

A+ Second Edition Genetic Computer School Tape Drives  Quarter-Inch Cartridges (QIC)  Digital Audio Tape (DAT)  Digital Linear Tape (DLT)

A+ Second Edition Genetic Computer School Some Interfaces  Small Computer System Interface (SCSI)  Communication Ports  Para llel Port  Serial Port  PCMCIA
