            Hypertext Markup Language which is often abbreviated as HTML
            is a <b>markup language</b>. <b>Markup languages</b> are
            typically used to encode information or data, but they differ
            significantly from <b>programming languages</b> which are

            programs should execute on a physical or virtual central
            processing unit (CPU).
