It is often abbreviated as <b>Mk</b> or <b>M</b>. This use of the word possibly originates from the use of physical marks made to measure height or progress. Furthermore, by <a href="/wiki/Metonymy" title="Metonymy">metonymy</a> the word mark is used to note a defined level of development or a <a href="/wiki/Product_(business)#Product_model" title="Product (business)">model number</a>. </p><p>The kind of products that use this convention vary widely in complexity. The concept shares some similarities with the <i>type</i> designation (in hardware), also called <i><a href="/wiki/Software_versioning" title="Software versioning">software versioning</a></i>: 1.0+ (1.1, 1.12, 2.0, 3.0, etc.), used to designate general <a href="/wiki/Software" title="Software">software</a> product releases, and other <a href="/wiki/Version_control" title="Version control">version control</a> schemas. Thus designations like "Mark I", "Mark II", "Mark III", "Mark IV", etc. come to be used as proper names for persons and products. </p> <meta property="mw:PageProp/toc" /> <div class="mw-heading mw-heading2"><h2 id="Application">Application</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Mark_(designation)&action=edit&section=1" title="Edit section: Application"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p><i>Mark</i> refers to a mark on the modification plate of a system, component or machine.
