No, RAM is a form of computer memory that is an integrated circuit, which uses electricity to read and write data. A laser beam IS used in CD/DVD drives though, where the laser detects differences in distance from tiny pits on the surface of the disc representing data.
Yes, optical disks use a laser beam to read and write data on the disk. The laser beam is focused onto the surface of the disk to detect and interpret the patterns of pits and lands that represent the data stored on the disk.
Laser light is used in CDs and DVDs to read and write data. A laser beam is used to either create pits on a disc's surface (writing data) or to detect the patterns of pits (reading data) as the disc spins. The laser's focused beam allows for precise and fast data access on optical media.
laser
yes
they have a micro chip and memory card
A DVD player uses a laser beam to read data encoded on the disc. This laser produces electromagnetic waves in the form of light to detect and interpret the data stored on the DVD.
Laser beams are used to read and write data on CDs and DVDs. Apart from writing on these disks, the laser beam can also be used to erase the data stored or even overwrite the data stored with fresh data depending on the type of disk used.
Modulation is only required if the data is being sent over a radio wave, or a laser beam. And even in the case of a laser, if you are content with on/off data streams, then there is no underlying signal to be modulated. Essentially all of the data whizzing round in your computer is doing so without the benefit(?) of a carrier - the wires are sufficient.
serial chip
The micro chip is assumed to be inside a device. To upload music directly into a micro chip would be impossible. If the micro chip in a device was built to store data you simply have to send the music into your device. Usually, devices that can store data are pendrives, MP3,MP4 players, cell and smartphones. Sorry, but your question is not so clear. May be you are talking about micro card.
it is what is known as eprom it basicaly stores information by programming a read only chip
A compact disc (CD) stores data by using microscopic pits and lands in its middle layer called the polycarbonate layer. These pits and lands are read by a laser beam in order to retrieve the stored information.
