As a paper. / Printer is an
Output device. / Toner-based printers work using theXerographic principlethat is used in mostphotocopiers: by adheringtonerto a light-sensitive print drum, then using static electricity to transfer the toner to the printing medium to which it is fused with heat and pressure.
The most common type of toner-based printer is thelaser printer, which usesprecisionlasersto cause toner adherence. / HP Officejet Pro 8500

SCANNER / In computing, ascanneris a device that optically scans images, printed text,handwriting, or an object, and converts it to adigital image / INPUT / Modern scanners typically use acharge-coupled device(CCD) or aContact Image Sensor(CIS) as the image sensor, whereas olderdrum scannersuse aphotomultipliertube as the image sensor. Arotary scanner,used for high-speed document scanning, is another type of drum scanner, using a CCD array instead of a photomultiplier. Other types of scanners areplanetary scanners, which take photographs of books and documents, and 3D scanners, for producing three-dimensional models of objects. / HP ScanJet G4010 PhotoScanner

SPEAKER / A PC speaker generates waveforms using theProgrammable Interval Tim / OUTPUT / In some applications, the PC speaker is affixed directly to the computer'smotherboard; in others,including the first IBM Personal Computer, the speaker is attached to alead, which attaches to aDC connectoron the motherboard. A wired PC speaker connector may have a two-, three-, or four-pin configuration, and either two or three wires.

MASS STORAGE / Incomputing,mass storagerefers to the storage of large amounts ofdatain a persisting andmachine-readablefashion / INPUT / Mass storage devices used in desktop and most server computers typically have their data organized in afile system. The choice of file system is often important in maximizing the performance of the device: general purpose file systems (such asNTFSandHFS, for example) tend to do poorly on slow-seeking optical storage such as compact discs.
Somerelational databasescan also be deployed on mass storage devices without an intermediate file system or storage manager.OracleandMySQL, for example, can store table data directly on rawblock devices. / L20/L40/L80 Tape Libraries
