Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Reading is an action performed by computers, to acquire data from a source and place it into their volatile memory for processing. For example, a computer may read information off a floppy disk and store it in random access memory to be placed on the hard drive to be processed at a future date. Computers may read information from a variety of sources, such as magnetic storage, the Internet, or audio and video input ports. The act of reading one unit of information (e.g. a byte) is sometimes called a read cycle. The electrical circuit that transforms the physical magnetic flux changes into abstract bits is called the read channel. A read error occurs when the physical part of the process fails for some reason, such as dust or dirt entering the drive.
