How about a tab for e-Hardware and one for Software vs. one for Manufacturing? They both indicate electronic communication devices and both can include advances, uses, problems, advantages, etc.

This is a puzzle I haven't completed also. The term "technology" is derived from the Greek word technologia meaning systematic treatment, as in art, skill, craft, e.g., the art of teaching, the craft of learning, and the skill of writing something. It refers also to bows, arrows, bolts, rivets, knives, cars, pencils, paper, prepared foods, etc.

I think a more complete term is advanced electronic communications technology (AECT) is better in a narrative or description of the use of the tab.
