Input, Output and Storage Devices

Input, Output and Storage Devices

1. Storage devices

   • Memory stick
     • USB memory sticks, also called pen devices or flash drives, are becoming more and more popular for the temporary storage and transfer of large amounts of electronic data. They should not be used as main data storage or to make permanent backups. This guide will help you understand how to use and look after your memory stick so as to ensure its effective and safe over a long period of time.
   • Portable hard drive
   • Fixed hard drive
   • SD card
     • SD memory cards work by recording data onto a solid-state chip inside the card using flash memory. The flash memory records information when electrical changes in its circuits. A similar process erases portions of the memory for rewriting.
   • Magnetic tape
     • Magnetic tape is a medium for recording , made of a thin magnetizable coating on a long, narrow strip of plastic film. It was developed in Germany, based on magnetic wire recording. Devices that record and play back audio and video using magnetic tape are tape recorders and video tape recorders.
   • CD
     • CDs are everywhere these days. Whether they are used to hold music, data or computer software, they have become the standard medium for distributing large quantities of information in a reliable package.
   • Floppy disc
     • A floppy disc, also called a diskette or just disk of thin and flexible magnetic storage medium, sealed in a rectangular plastic carrier lined with plastic with fabric that removes dust particles. Floppy disks are read and written by a floppy disk drive. (FDD),

2. Input devices

   • Artists Ipad
   • CD player
     • A CD player is an electronic device that plays audio compact discs, which are a digital optical disc data storage format. CD players were first sold to consumers in 1982. CDs typically contain recordings of audio material such as music.
   • WII Controller
   • Xbox Controller
   • Microphone
     • Microphones are a type of transducer- a device which converts energy from one form to another. Microphones convert acoustical energy ( sound waves) into electrical energy ( the audio signal). Different types of microphone have different ways of converting energy but they all share one thing in common: The diagram.
   • Mouse
     • An optical computer mouse uses a light source, typically an LED, and a light detector, such as an array of photodiodes, to detect movement relative to a surface. It is a alternative to the mechanical mouse, which uses moving parts to sense motion.

3. Output devices

   • Traffic lights
     • Traffic lights, also known as Traffic signals, traffic lamps, traffic semaphore, signal lights, stop lights, and (in technical parlance) traffic control signals, are signalling devices positioned at road intersections, pedestrian, crossings, and other locations to control flows of traffic.
   • Flash drive
     • A flash drive is a small piece of equipment used to store and transfer info for computers using a USB. Use the USB end of a flash drive to store music, photos or other documents from a computer with info from a certified computer or technician.
   • Remote controll
     • The main technology in home remote controls is infrared (IR) light. The signal between a remote control handset and the device it controls consists of pulses of infrared light, which is invisible to the human eye, but can be seen through a digital camera, video camera or phone camera.
   • Printer
     • In computers, a printer is a device that accepts text and graphic output from a computer and transfers the information to paper, usually to standard size sheets of paper. Printers are sometimes sold with computers, but more frequently are purchased separately.
   • Speakers
     • Speakers come in shapes and sizes, enabling you to listen to music on an IPod, enjoy a film at the cinema or hear a friend's voice over the phone.
   • Projector
   • Chip and pin device
     • A chip and device are designed to work in conjunction with the next generation of credit card terminals that have already been deployed in Europe.
   • Xbox controller
