The Full Form of ‘CD’ in Computer is ‘Compact Disc’.
Full Form of CD
CD stands for Compact Disc, a type of digital storage medium used to store and read data. A CD is a small, round, flat disc made from plastic or metal that can store up to 700 MB of digital information. It was developed in the early 1980s by Philips and Sony as an alternative to magnetic tapes and floppy disks. The CD quickly became popular due to its ability to store more data than other storage media.
The inner layer of the CD contains pits and lands that are arranged in a spiral pattern. This spiral pattern is encoded with digital information, which can be accessed when the disc is read by a laser beam. The pits and lands cause the laser beam to be reflected differently, allowing it to “read” the data on the disc. CDs are often used in computers and other electronic devices such as DVD players, video game consoles, car stereos and portable music players.
A standard CD has a diameter of 120mm (4.7 inches) and a thickness of 1mm (0.04 inches). There are two types of CDs: write-once CDs (CD-R) and rewritable CDs (CD-RW). Write-once CDs are designed for one-time recording only; once data is written onto them they cannot be changed or erased. Rewritable CDs can be written onto multiple times; the data stored on them can be changed or erased as needed.
In addition to storing audio files such as music albums, CD discs have also been used for storing computer programs, video games, digital photos and videos, text documents, spreadsheets and other types of multimedia content. They have also been used as an inexpensive way to distribute software applications over the internet since they are easy to copy and transport from one location to another without any loss in quality or performance.
Compact discs remain popular today despite the emergence of newer digital storage media such as USB flash drives and external hard drives which offer higher capacities at lower cost per gigabyte than traditional CDs do. This is because CDs offer advantages over these newer technologies such as being more resistant to physical damage (such as scratches) than flash drives or external hard drives are; being easier for most people to use since all you need is an optical drive; having low power consumption requirements; not needing additional drivers or complicated installation processes like some other forms of removable storage do; and being compatible with almost any device that has an optical drive port available – including computers, DVD players, game consoles etc…
In conclusion, CD stands for Compact Disc which is a type of digital storage medium used widely in computers and other electronic devices today due its superior storage capacity when compared with older storage media such as magnetic tapes or floppy disks; its great resistance against physical damage; its low power requirements; ease of use; compatibility with most devices that have an optical drive port available – including computers, DVD players etc… And finally because it remains relatively inexpensive when compared with newer forms of removable storage such as USB flash drives or external hard drives offering higher capacities at lower cost per gigabyte than traditional CDs do
