Computer Science or Info Tech?

An anonymous reader writes "I am currently completing my final year of secondary schooling, and in the next few weeks I need to submit my university (or college to all you Americans) preferences for processing. I've decided that I want a career in the IT industry, but am unsure of whether to apply for a Computer Science course or an Information Technology course. I understand the difference between the two courses (CS being the study of the principles and concepts involved in Computing at a more fundamental, and often more sophisticated level, and IT being a more practical, application based approach to computing), but would like to know from anybody who has studied either or both of the courses what kinds of careers each course would lead into and what would you recommend for someone such as myself, having a broad range of interests and wishing to dabble in everything before deciding where to specialise?"

CS vs IT

[pentalive]

So which do you prefer being - A system admin (follow IT) or a programmer (follow CS). They are not mutually exclusive. As a system admin I do a lot of programming. My boss in my last job favorite question was - "How can we automate this?". I like being a system admin myself - I get out of the cubicle more that way.

p.s. first post and actually fairly on topic :^P

Actually this isn't quite correct, at least not where I live (UK).

IT is drudgery. It involves looking at how people use computers in everyday tasks... The fact that you read slashdot shows that you will find IT hugely boring, seriously. I've done two seperate IT courses, one for GCSE and one for A-Level. Both were as bland and meaningless as eachother.

During coursework I tried my hardest to get down to some technical points, but the specification doesn't allow for that kind of thing. It is more of a kind of "look how magic computers are? they run on magic!" kind of course, you never get down to the nitty gritty.

CS on the other hand is a level-up. The social sides of computing is less studied, and computers themselves are more studied. ICT is a general "I can do computers, me" course, whereas a CS degree is a) more interesting b) more challenging c) employers will recognise b :)

I was an IT major and switched to CS for several reasons:
* CS is more dificult, that's why I originally chose IT! I feared the math (IT requires 2 math courses while CS was closer to 9 but all ultimately most courses had a math background. CS is more math centric but you appreciate the inner workings of the field
* IT is more high level and you never quite dwelve in deep enough to appreciate things
* A good CS major can do any job an IT major can, but an IT major can not do everything a CS major can, so don't limit yourself!
* Whether you want to do sys admin or programming CS is a good choice, you'll learn how things work and you'll be better at troubleshooting advanced concepts.
* CS teaches you the theory. It's less practical application oriented but once you understand and appreciate the theory you can easily lean anything.
      - Consider: A job might require you to program in visual basic to interface with an Oracle DB. If you went in IT, they might have taught you to use VB and Oracle, so you're all set. In CS, it's unlikely you did either but you took a programming languages course and a DB theory course which enables you to learn almost any language in a day. Now consider you get asked to switch from VB to C# and a mysql db. In IT you never touched either and you don't understand the basic language concepts so its harder for you to pick up both. With CS you still have the theoretical background with enables you to pick it up in a day. The same analogy trancents multiple areas (not just programming) like networking, operating systems, etc. This also applies to those who don't get a degree and just get a bunch of certs, eventually those certs become obsolete and its harder for those without a CS degree to adapt.

The only thing IT has over CS is some basic business courses, but if you get a CS degree, getting an MBA is trivial.

While you could well be right, the one absolute in university-level computing courses is that everything is relative.

Some places have an old-school CS course that teaches strong theory and is quite mathematical. This is probably good for someone who wants to deal with challenging programming work in the future: the kind of person who wouldn't just be writing a web front-end to use a database, they'd be writing the compiler and the database engine. These courses probably won't teach you to program in this week's greatest programming language or web/DB framework. What it will give you is a solid understanding of the principles and exposure to a broad range of ideas. With that sort of perspective, a CS grad should make short work of getting up to a reasonable level of competence in any industrial languages and technologies.

Sadly, it seems like an increasing number of places now run a "computer science" course that is basically just the latest industrial buzzwords. If you're looking at a course that teaches things like VB, XML, Windows/Linux system administration, business studies, web design, and the like, then IMHO that's not really computer science at all, it's just vocational training.

The potential scopes of other courses, such as "Information Technology", "Information Systems", "Software Engineering", are similarly wide-ranging, so it's hard to give advice about which course is best for someone without being able to see the details of what each really covers.

I don't think it's so sad that there are relatively few places that teach the more theoretical forms of CS. Relative to other disciplines, there was an imbalanced excess of programs teaching skills that only a small number of people would need, and the kind of invention you describe will probably be done by people with a graduate education, anyway.

The thing is, I don't think a CS education is something only a small number of people would need. Sure, it provides a deep understanding of some areas that little else does, but it also provides a broad base on which to build anything else you need in less specialised areas.

Put it this way: people who go into writing software without the kind of understanding of database construction and system design that a good CS course would teach are often the reason we get ludicrously slow applications, with ever-increasing hardware requirements, littered with security flaws, and the design behind the code — if it has one at all, instead of misunderstanding the buzzwords and thinking a set of tests is a substitute — is such a mess that no-one can fix it, and you have to either live with it or throw it all away and start from scratch.

(Before anyone replies, please note that I wrote "the kind of understanding ... that a good CS course would teach". Studying a formal CS course is certainly not the only way to gain this understanding.)

Essentially correct

[nyteroot]

The above is a little inflammatory, but essentially correct. There is no job you could get as a IT major that you could not get as a CS major. There are many, many jobs you could get as a CS major that you would _not_ get as an IT major. Additionally, you may find yourself _interested_ in the science-y aspects of CS, and perhaps even go on to graduate school -- an avenue which would not only be blocked off as an IT major, but of whose existence you would not even be aware.

Choose scientist over technician.

Re:Think 15 years down the road

One option if you can make the time for the investment is to add either a minor, double-major or emphasis in a non-technology field, especially if you're looking at the IT path. This approach will set you apart from other candidates and puts you in a position to be able to communicate and understand problems in specific business domains.

For example, while the Fortune 250 firm I work for is shedding programmers and analysts like mad for outsourced options, it is also hiring project managers, auditors, information security analysts and risk managers who have a non-IT specialization like finance, marketing, legal/regulatory in conjunction with the IT foundation. These multi-domain specialists are critical in moving projects forward, especially when the programming staff is outsourced and someone has to relate business requirements to the outsourcing resource.

Having come up in telecom and IT, I went back and added a finance degree a few years ago and am now completing a masters in economics. I went from having a tough job competing over scarce network engineering positions to a senior position in operational risk. The key was mastering more than one business domain so my employer found I could work between different business units. Many of my friends who've been successful have taken the same approach and it is a great way to reach into a six-figure salary pretty quickly.

If you find you're quantitatively inclined, you might consider getting a double major in finance or statistics to complement that IT degree, rather than focusing on a CS degree. The quant can be harder and the job market is significantly different. Countless firms have a shortage of IT analysts in finance, data mining and other corporate decision-making fields.

As long as you're a replaceable commodity, you'll be at risk to outsourcing and low salary issues. Become someone who can help management understand their problem area and relate it to a technology solution and you'll do very well.
