1984 cds, dawn of the digital revolution

The introduction of the compact disc, or CD, was the beginning of a ‘digital revolution’ which now dominates electronic media.

Introduced in 1982, the CD was slow to catch on. The sound was crisp and clear and the discs did not scratch as easily as vinyl records. But people had to buy new machines to play them – and were reluctant to replace their record collections

Despite the slow start, people did start buying the discs and their players, especially when prices began to all and major stars began to release albums on the new media. By 1988, sales of (digital) CDs had outstripped sales of (analogue) records. Since then (digital) DVD has largely superseded (analogue) videocassette for delivering films.

The wavy groove of a record is direct representation (an analogue) of sound waves. In digital technology, sound waves are represented by a succession of binary numbers instead. On the underside of a CD is a spiral track containing tiny indentations which represent the digits 0 and 1. This is scanned by a laser in the CD player and decoded into sound.

The quality of recorded sound on a CD is very high. But something very close to CD quality can be recorded using far fewer binary digits per second – a smaller amount of digital information. This led to the development of compressed audio formats, notably the ‘MP3’ (MPEG layer 3). Images and video can also be ‘digitised’- converted into a stream of binary digits.

The increasing popularity of the personal computer in the late 1980s and 1990s did much to encourage the uptake of digital technology. As processing power increased, personal computers became able to manipulate the large numbers of binary digits required for computer-based ‘multimedia’.

Today, most people receive digital television signals; they speak on digital mobile telephones; they capture video; they listen to digital music on CD, on their computers or on mp3 players. Whether they are carrying sound, text, images, video, or a combination of all four, all digital technologies are doing is manipulating streams of binary digits.

Answer 1

The development of CDs
when you listen to the music, have you ever thinking about how it bring out? And what’s the meaning about ‘digital revolution’?
We should talk about since 1982;the discs were not vinyl records like now. The sound of music was so crisp and clear that people had to buy new machines to play to replace their record collections.
The CD was slow to catch on, because the price is too high. Nevertheless, when all and major stars began to release albums on the new media, people did start accepting these new discs. Furthermore, since then (digital) DVD has largely superseded (analogue) videocassette for delivering films by 1988, sales of (digital) CDs had outstripped sales of (analogue) records.
The sound waves like the wavy groove of a record (an analogue), which are represented by a succession of binary numbers instead in digital technology. It represents the digits 0and 1 and contains tiny indentations on the underside of a CD.
In this way, the quality of recorded sound on a CD is much higher than before. However, a smaller amount of digital information before long, which very close to CD quality can be recorded but far fewer binary digits per second. This led to the development of compressed audio formats, which is what we have known –‘MP3’ (MPEG layer 3). This format can makes images and video can converts into a stream of binary digits, which called ‘digitised’
With the increasing popularity of personal computers, digital technology was much uptakes in the late 1980s and 1990s. For the power processing of personal computers, the binary digits required was able to manipulate the large numbers by computer-based ‘multimedia’.
Now, we can use digital technologies in many ways, such as digital television signals, digital mobile telephones, capture video, even more digital music on CD or mp3 players, all digital technologies are doning is manipulating streams of binary digits in any way.
