The Internet and information technology are affecting engineering to its core.
Engineers use IT in increasingly deep ways.
Nearly every engineering discipline now uses sophisticated design and graphics tools to prepare sketches, plans, and diagrams. These tools are often linked to analyzers, simulators, and manufacturing machines. In the workplace it's going to be expected of every engineer to use these tools to do their jobs. Don't wait for a course to learn these tools. IT technology is moving forward rapidly and relentlessly.
