Reading (computer)

<p>Reading is an action performed by <a href="/facts/Computers/SQe1aK05">computers</a>, to acquire <a href="/facts/Data/AUBFN97o">data</a> from a source and place it into their <a href="/facts/Volatile_memory/SvvPe9XB">volatile memory</a> for <a href="/facts/Process_(computing)/Vcq7EnUV">processing</a>. Computers may read information from a variety of sources, such as <a href="/facts/Magnetic_storage/QaK6oArm">magnetic storage</a>, the <a href="/facts/Internet/Xw1rVvJU">Internet</a>, or <a href="/facts/Sound/DlKXlPuF">audio</a> and <a href="/facts/Video/F1AV8ben">video</a> input <a href="/facts/Computer_port_(hardware)/87F2NcNc">ports</a>. Reading is one of the core functions of a <a href="/facts/Turing_machine/ojCtglYu">Turing machine</a>.
</p><p>A read cycle is the act of reading one unit of information (e.g. a byte). A read channel is an electrical circuit that transforms the physical magnetic flux changes into abstract bits. A read error occurs when the physical part of the process fails for some reason, such as dust or dirt entering the drive.
