Computer Technology vs Information Technology | The IT Digest

The exact answer depends heavily on the college or university in question, as each tends to split things slightly differently. As a generalization, there are actually three fields commonly associated with computers:

Information Technology ? this sometimes also goes by the names ?Information Systems?, ?Systems Administration?, or ?Business Systems Information/Administration?. This is a practical engineering field, concerned primarily with taking existing hardware and software components and designing a larger system to solve a particular business function. Here you learn about some basic information theory, applied mathematics theory, and things like network topology/design, database design, and the like. IT concerns itself with taking building blocks such as servers, operating systems, network switches, and software applications and creating a whole system to solve a problem (such as creating a sales order handling systems).

Computer Science ? this is a theoretical field, with emphasis on the mathematical basis which underlies modern programming. That is, computer science is primarily software-oriented, as it concerns itself with developing new algorithmic ways to solve a problem. Such algorithms are then actually implemented in software. Here you will learn about the fundamentals of programming languages, a large variety of information theory and algorithm theory (plus, linear and discrete mathematics), how to design a software program, and how to run a successful software development team. CS can also encompass items such as compiler and Operating system design and implementation. In general, if it concerns actually writing any form of software, whether to solve a practical problem or as part of a more academic research project, CS is the place to be.

Computer Engineering ? this is an hardware engineering field. Some places treat it as a specialty of Electrical Engineering. This field teaches the design of hardware components, and also the assembly of those components into a larger hardware system. It encompasses information theory, electrical engineering, VLSI design, and digital logic. Here you will be involved with designing CPUs and other Integrated Chips to perform specific tasks, and will also learn about very low-level programming (usually, the type of programming use to create firmware). In essence, CE involves the creation of hardware devices intended to perform a very specific function (e.g. a modem, a CPU, a DRAM chip, etc.)
