What are the major differences between Software Development and Information Technology. If you have majored in IT is it a fine major but as different as Software Development and Computer Science as stated in Joel's blog?
If you want a career in software development, it will be harder to start out with an IT degree. With the right career focus, I'm sure you can become a solid programmer but it will be harder to get onto that career path with a bachelors in IT. Many companies will pass you over for better qualified CS candidates.
IT will give you exposure to computer systems, administration, application of hardware and software systems. A CS degree will not cover that in the coursework, however you will probably be exposed to most of it at some point in time.
CS will focus on software development principles, data structures, algorithms, language syntax, operating system development, parallel programming, artificial intelligence, etc.
My theory is that it will be easier to go from a specialization (CS) to generalization (IT) than vice-versa.
Information Technology is the wider discipline of which software development is a part.
Information Technology would commonly cover not only software development but hardware, system administration, networking, implementation as well as related but non-technically hands-on disciplines such as project management and business analysis (which might in turn cover more general business knowledge).
Software Development on the other hand specifically relates to the development and implementation of applications either from scratch or as a heavy customisation of an existing solution.
Of course it's impossible to know for sure how generalisations will apply to specific courses or companies and the way they use those terms and it wouldn't be unreasonable to have a broader or narrower definition.
In terms of which course is better, that likely depends on whether you want to be a programmer (in which case a Software Engineering / Computer Science course is likely to be more useful), or if you're not clear and might want to try something different within the industry and want something a bit more general.
But I wouldn't get too worried about it - the differences are likely to be minor enough that they're unlikely to impact you career choices later in life so it's not going to be a big mistake if you choose the "wrong" one.
