Information Technology is technology that involves information manipulation and storage. Development and software engineering are subsets of IT, infrastructure maintenance is another.
Computer Science has nothing to do with computers, or science. It is generally a mistake to read the name of something as defining that thing β it has almost certainly shifted meaning since itβs origin, especially if someone is arguing about it.
I disagree with you there. In Computer Science, you learn the science(determined truth) of computation(the act of mathematical calculation). The names of most degree programs are pretty accurate when you really parse the jargon.
