Optical storage devices

 Optical storage devices

How people at home and business uses store and calculate modifies functions thereby manufacturers designing

and marketing their products on the computer. Quite recently, almost all PCs and laptops have optical storage

devices, such as CD, DVD or Blu-ray disc, which installed internally. However, this situation with slimmer, smaller,

faster product has changed with the growth of the Internet and cloud computing services. For this reason, to reduce the need for these devices during the year.

Primary and secondary memory

 

Main memory is temporarily on your computer and data internally to keep. Random access memory (RAM), are

examples of cache storage capital have faster access to the data. An internal or external components such as hard drives and solid state drives (SSD), and optical drives, and USB flash drives, also known as Flash drives or USB sticks are called secondary memory, external or additional memory.

Optical storage media

Optical storage media storing data written and read using laser technology. The three most common optical media is CD, DVD and Blu-ray. CDs and 300,000 pages of text about 700 MB. Usually used for DVD movies and memory to hold about 4.7 gigabytes. Blu-ray DVD five times the storage and use of movies in hi-def (HD). Click you can burn 25 GB on a single-layer Blu-ray data disc and dual layer drive 9 hours can record HD movie or about 50 GB of data. We expect during the year for Blu-ray discs, DVDpreference as a Visual means to replace. 

 Use of cloud storage

The use of cloud storage, data on servers that are usually the hosting services use has grown explosively in recent years. Convenience and simplicity in dealing with smog,the low cost of entry and user related computer all

backgrounds flock to these services. There is no need to consume more disk space to files on your laptop or desktop or backup files to the optical storage device. Just use an external cloud service like Dropbox, Amazon or Google your information store. There are many to choose from. You can access what you need from any device that is connected to the Internet.Is simple and easy, safe, inexpensive and reduces the need for optical disk storage.

Use development of download and streaming services Has a hard copy of the programs, software, movies, games and music to Visual media such as CD, DVD, or Blu-ray buy traditional. But software companies and gaming companies and video, and music streaming services offer the same content and information via the Internet, the cost now for download or monthly subscription. For example, instead of a watch a DVD movie, the box or hardware can now deliver services that have been developed for the same content to see that. This eliminates the need for optical storage media and optical storage engine.
