Information technology (IT) is the use of computers to store or retrieve data and information. IT is typically used within the context of business operations as opposed to personal or entertainment technologies. IT is considered to be a subset of information and communications technology (ICT). An information technology system (IT system) is generally an information system, a communications system, or, more specifically speaking, a computer system – including all hardware, software, and peripheral equipment – operated by a limited group of IT users.
Humans have been storing, retrieving, manipulating, and communicating information since the Sumerians in Mesopotamia developed writing in about 3000 BC. However, the term information technology in its modern sense first appeared in a 1958 article published in the Harvard Business Review; authors Harold J. Leavitt and Thomas L. Whisler commented that "the new technology does not yet have a single established name. We shall call it information technology (IT)." Their definition consists of three categories: techniques for processing, the application of statistical and mathematical methods to decision-making, and the simulation of higher-order thinking through computer programs.The term is commonly used as a synonym for computers and computer networks, but it also encompasses other information distribution technologies such as television and telephones. Several products or services within an economy are associated with information technology, including computer hardware, software, electronics, semiconductors, internet, telecom equipment, and e-commerce.Based on the storage and processing technologies employed, it is possible to distinguish four distinct phases of IT development: pre-mechanical (3000 BC – 1450 AD), mechanical (1450–1840), electromechanical (1840–1940), and electronic (1940–present). This article focuses on the most recent period (electronic).
I had applied one month ago into some universities, with the aim of switching my university major. (I studied history). I went to the entrance exams for computer science and engineering oriented fields, and waited anxiously for 1 month.
I was not sure whether or not my entrance exam score was...
I met with a professor/teacher advisor for the CIS (Information Systems) major. They said it's probably not for me, based on my career intentions.
I'm intending to start a startup IT corporation ASAP as a career. I need the knowledge of (many, several) programming languages for my intentions...
I am currently one class away from acquiring an AA in IT. I have a 3.6 in the IT academic program (3.38 overall due to failing my first programming course this semester). Weirdly enough, math and science are my weaknesses. I was initially a Psychology major (3.72 degree audit) and chose to not...

HI everyone. I was just wondering about a career in the IT (I study communication systems engineering, but I'm rather interested in coding, rather than Internet and communcation systems- related stuff). I wanted to ask you, given the advances that technology is making, which skills would be...
I have an AS degree in Computer Science. I'm in the process of transferring to a 4-year university to pursue a BS in Envionrmental Science. I've always been heavily interested in computers, including running my own web & email server, database administration, hardware, and networking. I have run...
I hear that there is thing out there with communication with in all types of systems and it is called Information Technology (IT for short) Can some one expand upon this field of engineering, I would like to know a little bit more, And as always, Please and Thank you!
Dear All,

I am currently a student at USF majoring in Computer Science. I am almost positive that I will be switching to Information Technology after this semester. This is primarily because I do not want a job in software development anymore. I still have 43 credits left to complete the CS program. I...
Hi!
Can anyone (or everyone) explain to me some areas of information technology and what jobs exist there? It's one of my few options and I would like to know more about it. What kind of jobs there and your opinion about that career in future?
Thanks in advance.
I am a Computer Science major and as of now, I am starting to feel like this is not want I want to do with my life. I want to be involved in the management aspect of technology. I don't know which degree will take me there. I am currently taking Data Structures and I hate that class. I feel like...

Right now I'm majoring for a BS in Information Technology at a 4-year university. This is kind of a risky major since it's new and pretty much a watered down version of Computer Science, I think. Anyway, I'm not sure where I want to go with my career. There are many branches to take in IT like...

Problem:
I have heard of a word(s) with the meaning: "instructions on how to find information", so that instead of telling someone a piece of information straight away, one tells how to find the information. For example: Someone asks, I want to eat a great cookie. The answerer gives not the...
