Input/Output/Storage

Input Devices Computers need to capture information. This can be done using an Input device

Input Devices They fall into six categories: Touch Touch e.g. keyboard, mouse Magnetic Magnetic e.g. credit cards, smart cards Light Light e.g. barcode readers, optical mark readers, scanners Sound Sound e.g. voice recognition Control Switches, e.g. on a speaker, monitor etc Control Switches, e.g. on a speaker, monitor etc Chip Readers, e.g. chip and pin card readers Chip Readers, e.g. chip and pin card readers

Output Devices These are the devices that allow us to see the information that we have created e.g: VDU’s (Monitors) VDU’s (Monitors) Printers Printers Sound Sound Robots Robots

Storage Devices A storage device will hold all of the information even when the computer is switched off e.g: Hard disks Hard disks Floppy Disks Floppy Disks Removable Media Removable Media e.g. zip disk CD’s CD’s DVD’s DVD’s Magnetic Tape Magnetic Tape USB Memory Sticks / Pens USB Memory Sticks / Pens
