Although the use of CDs is very less at this time, CDs are not required for any purpose anywhere, but there was a time when CDs were used a lot but even now the new generation of children don’t have any idea about CDs at all.
Do you know what is CD, what is the full form of CD, if you do not know, then in this article you will learn what is the full form of CD and what is the full form of CD and before we told you about DVD If you have not read it yet, then read it now and get information about what is DVD, what is the full form of DVD.
Those who know about CDs who have used CDs may not have any idea about the full form of the CD because it seems like this is a full form, but the CD itself is not full word rather it is a short form.
And as I’ve given you a link to the DVD, I want to point out that the structure of the CD and DVD is the same so that both the CD and DVD can be used on the same drive, but both of them are very different in power and speed.
What is CD What is the full form of CD
What is the full form of CD
Full form of CD – Compact Disc
A CD is a molded plastic disc with a reflective metallic layer in which different types of data are stored and that data cannot be viewed or read normally, to store or read data of CD requires a CD Player, by inserting CD in the CD player data can be accessed
The task of reading the CD is mainly processed by laser beam, which is already installed in the CD drive/player, which we also know from the name of the lens.
When and who invented the CD
It has been said that the requirement is the mother of invention, just like that, the CD was invented by James Russel in 1960, who was a physicist and James Russel was born in Bremerton, Washington in 1931.
James Russel achieved his graduation degree in 1953 after which he started working in an electric lab, James was a lover of music, and his hobby invented the CD.
At that time vinyl (Polyvinyl) record was used for music, James Russel also used vinyl to listen to music but was very disappointed with the sound quality of his vinyl and this disappointment led to the invention of the CD.
CD was invented by James Russel in the 1960s, but even then CDs were an unknown thing to people because CD was founded at that time, but in 1982 Philips and Sony started to develop cd because it was the best option to store cd data according to that time.
And the world’s first CD player launched, called Sony CDP-101, and that’s where the cd started using it professionally.
Even though this time CD has become an outdated product, that time CD used to be a very basic thing because there was no other option of data storage except that time CD.

Which was the world’s first CD player
The first CD player in the world was the Sony CDP-101 which cost 1000 USD, which is a huge amount and that amount was too big for just one CD player, but over time the prices of cd players continued to fall.
Which was the world’s first cd
52nd Street was the first CD in the world that cost around 30 USD at the time and like a CD player, its prices also dropped, because these were not products that cost a lot but at that time CD was a unique product. For some time, its price was very high and over time its price decreased.
What is a CD player
CD is not a tool that can give us the output, CD is just a disc in which we can store the data, but if we need to access that data, we need a device that can read the stored data in the CD, we can also call the CD player to a CD reader.
Different types of players are present for different types of CDs.
Capacity of CD
Although the storage capacity of a CD is less than 1 GB, that is, only 700 MB, but when the CD was invented, at that time CD was the best option of storage and its capacity was more than the other resources.
Although pc cards were invented in 1980, no one had the phone at that time, so who used the memory card, so the CD was most used at that time for data storage and for the collection of different types of media files.
Because everyone could buy a CD player and almost everyone likes to listen to musics and it was possible to store audio, video, software programs on CDs too, CDs became very used in every industry, just to read data of cd requires CD player/Reader.
Although the TV was invented long before the CD, there was no best device for the storage of TV programs that the CD and CD player completed, the CD and pc card was invented in almost a decade and 1800 – 1882, and that decade was a revolution in the electronic industry.
Even though both were invented in the same decade, but CDs were used a lot from the initial decades to a few decades, as CDs were used for all kinds of projects, small and big at that time but the use of pc card (memory card) Used only for large projects.
And the memory card gradually made the CD an outdated product. You can see for yourself today, the memory card is used everywhere, this time the two primary methods are of data collection, hard drive (equipment used in the computer), Memory cards (external storage, phone storage), and CDs have completely collapsed, although CDs are still used for some programs but it is gradually decreasing

CD vs DVD
Although both CDs and DVDs are on the verge of collapse at this time, CDs had a much greater impact after the invention of DVDs because DVDs can store a lot more data than CDs and have higher speeds than CDs.
The only difference between CDs and DVDs is that DVDs are more efficient than CDs, where CDs have the highest storage capacity of 700 MB, while DVDs have the highest storage capacity of 17.08 GB. Similarly, DVDs have many more features. Get from here what is DVD what is full form DVD
Reasons why cd/DVD is low used
No one needs a CD at this time, no matter the content, whether it is a TV program, computer program (software), etc. because this time all the things people get to see and use on their smartphone, there are two main reasons why the CD is on the verge of collapse, Satellite TV, Mobile, Computer (Internet), because they get us in all kinds of data (Movie, Songs, Games, etc.) for free and that too very easily.
What is the type of CD
It is obvious that at the time of the invention of CD, all types of data could not be stored in it, since it was decided that all types of data can be stored in CD, but the CD was invented mainly to store music of better quality, which was James Russel’s idea.
And in the early decades, the first music CD was made and it’s player which we have given full information above, and with the overtime, along with the improvement in CD and CD reader/drive, storing all kinds of data. made possible.
And depending on the CD’s ability to store different types of data, different names of CDs are given, that is, CDs are of different types, which is as follows.
Audio CD (CD-DA)
This was a primary CD, since the audio CD was invented, it was a CD in which audio was stored and sold, in addition to audio, no data could be stored in this CD.
Initially, a very simple audio CD was prepared, whose sound quality was also normal, this CD could store only audio and could be played on the player.
But after some improvement, it was able to collect data like song name, artist, etc., which is known as CD-T i.e. compact disc text.
Due to the continuous improvement in CD and CD player, it became possible to store audio as well as graphic (CD-G) in CD, as long as the CD was available in the text version, the song information (song name, album name, etc.) could only be seen in the CD player, but after adding the graphic, it could be displayed on CD tv, monitor.
But that graphic could not be displayed by the normal audio player, instead, it required a graphics-based CD player that could display that graphic on tv, monitor along with audio.
And that’s where VCD (Video Compact Disc) was possible to display graphics on tv through THE CD, but the video CD was not developed after CD-G, but after CD-G the CD of CD-EG type was prepared i.e. Compact Disc Extended Graphic
After the development of CD-EG, the texts, Graphics were displayed on the TV in the best quality.
In 1993, a video CD developed that could store audio as well as video, the CD became very popular in a very short time, and the video CD became the best-selling CD.
Super Audio CD
Super Audio CDs were developed for better sound quality, but still, it was only an audio CD.
Super Video CD
super video cd was a new form of CD because it made the graphic quality much better, because the quality in the first video version CD was not very good and the quality was improved so it was given a new name SVCD.
The photo cd was a cd designed by Kodiak that was used to store photos, with about 100 high photos to be stored and used for different purposes.
What is cd ROM
You may have a lot of doubt about the CD ROM because ROM is attached to it, and mobile/laptops also have ROM, so obviously, there will be doubt.
These CDs are also like normal discs but they are only readable, no changes are possible in them, the data stored in them can be read by the player/CD driver but you can neither delete the data stored in the CD ROM. Nor can we put any more data in it.
What is the full form of CD ROM
CD ROM full from – Compact Disc Read-Only Memory
Recordable CD (cd-R)
By the way, CDs are provided by the company but recordable CDs have also been developed so that anyone can record themselves very easily but for this, a recorder was required.
That is, if you want to store any data on the CD, then you can store it on the CD by recording through the recorder and play it on the player.

Rewritable CD (CD-RW)
It is a separate CD from all other CDs because in all other, if you store a data or company or does anything, it does not have any problems, but you could not store any other data instead of that stored data.
But the ReWritable CD is the most different of those in this CD, no matter what data is stored in this CD, rather you can also store any other data instead of that data.
Some other CD types
So I hope you have liked this article about CD, although CD is not used at all at this time, still, you must keep information about what equipment was used at the place of memory card Earlier as storage which is the CD.
