Optical discs, such as CDs and DVDs, use pits and lands to store information. Pits and lands are variations in the physical surface of the disc that represent binary data (0s and 1s) which is read by a laser during playback.
Digital Versatile Disc (DVD) uses 650nm wavelength laser diode light (part of the electromagnetic spectrum, in visable light section) which allows us to see it. CD uses 780nm wavelength, just outside of the electromagnetic spectrum, hence why we cannot 'see' it, only hear.
-> store and release energy -> Transfer energy all in a cell
It uses water and horse power and stuff
Store some of it as Starch .Some plants also store energy by converting sugar to lipids.
an unmanned device that uses technology and sends information back to earth
The recessed area on a CD or DVD where data is stored. CDs and DVDs store data in lands and pits. The lands represent 1 and the pits represent 0 in binary computing. The bits are read by the disc drive that uses a laser beam to distinguish between the lands and pits based on the amount of scattering or deflection that occurs when the beam of light hits the surface of the disc
Cd- rom
databases are used in school to store the information of students ,offices to store the information regarding the workers etc . It is more efficient that excel sheet.
A DVD drive uses a laser and an optical lens to read the surface of the disc itself, which contains several pits that contain data. If the laser hits pits, it is a 1. If not, it is a 0. The laser, containing data, comes back from the mirrored disc surface and into the optical lens, reading the information and therefore changing it into graphics, audio, and useful information.
A computer's hard-drive.
Computers are used in shops to store information on what is bought, how much is made, etc.
Business uses information system in various ways. The most common use is to communicate and also store up information that is relevant to the business.
A new experimental storage medium called "Spintronics"
the hard drive is the main drive because it has all your windows information in it.
A compartment box is used to store different items. You can use it for gloves, maps, pens and paper. Some people use it to store their car information.
While the debit card uses a magnetic strip, the smart card typically uses an embedded semiconductor to store and maintain information.
Information technology(IT) sector is the firm which uses computers, advanced technology to transmit, develop and manipulate, and to store useful data.
