ngineering in information technology refers to how specific
technical problems are solved.While radio waves might be
the technological precursor of mobile phones, for example, a
handset without an engineered network is useless technology.
Engineers create, develop, and build the background structure
that enables the use of technological devices. Sometimes, the
dividing line between technology and engineering is a fine one.
