A Molex Connector connects to optical drives and hard drives.
no, sata drives transfer all of the data through the sata cable
CD & DVD burners are optical drives that can write data to CDs or DVDs.
The purpose of secondary memory is storage of data that is not immediately needed for processing by the CPU. Examples of secondary devices are hard drives and optical drives.
Optical Media like CD/DVDs and hard drives are pretty affordable
CD and DVD disks are used by optical disc drives.
An optical drive is for reading and possibly writing to optical media such as a CD or DVD. It is pretty much used like any other drive in a computer. Older optical drives could only read data and could not burn disks.
No. Optical storage is something that can be read using the aid of light. So CD's, DVD's would be examples of optical storage. Spinning hard drives are not optical either. They use magnetism to store data.
Most optical drives use two connections. The first connection is for power. The second connection is for data. Of course, it also uses screws or clips to attach it to the system.
According to http://www.answers.com/optical+drives, David Paul Gregg developed an analog optical disc for recording video and patented it in 1961 and 1969.
An optical drive, or more accurately an optical disk drive (ODD) is medium for storing digital data. Examples are CD, DVD and blu-ray. The characteristic of an optical drive system is that beams of light (typically laser) are used to read the medium.
Data on hard drives, flash drives or optical media (DVD, CD) is stored in binary format. This means that the data is reduced to 0's and 1's. A "CD Pit" is one of the 2 states of data (normally, a pit is a 1, no pit is a 0)
