We can simply define Information Technology as “any technology through which we get information is called information technology”.

Often times, the term IT is applied to computers and computer-based systems. However, the roots of the word technology suggest that it is a “means” to an end”. For example, using a book of matches is a means to creating a fire. The end is fire itself. A bicycle is a means of transportation. The goal of bicycle riding is to reach a destination, and perhaps also to get some needed exercise.

Consequently, when we talk about the use of technology, we must always remember that it is a means, not an end in itself. Technology in the broadest sense is the application of modern communications and computing technologies to the creation, management and use of knowledge.

IT is the study or use of systems (especially computers and telecommunications) for storing, retrieving, and sending information.

the system involving the development, maintenance, and use of computer systems, software, and networks for the processing and distribution of data.

The meaning of information technology is broad, encompassing all forms of technology that involves any form of electronic data.

IT is more about information manipulation and application focused...... where as computer engineering covers more about computer architect and peripherals.....

Dear @Dr. Vaishali,

Don't you think maximum points (except last one) you mentioned are also related with the computer engineering? 

@Md Asraful Haque

the concepts and difference of IT and computer engineering vary a lot from author to author .... there is no single point conclusion... even in syllabus of courses titled with IT and CE differs a lot from university to university.... one has to understand it according to its own perception and need base...... as single point conclusion is difficult to arrive....

Computer engineering focuses on hardware development, computer science focuses on software development, and IT focuses on running production systems that somebody else has built. Computer science and computer engineering are usually harder work to learn and are somewhat interchangeable in what jobs you can qualify for. IT usually contains business focused classes as well as some of the lighter technical classes.

Dear Colleagues,

Good Day,

 Information Technology Definition

Set of tools, processes, and methodologies (such as coding/programming, data communications, data conversion, storage and retrieval, systems analysis and design, systems control) and associated equipment employed to collect, process, and present information. In broad terms, IT also includes office automation, multimedia, and telecommunications.

Any equipment or interconnected system or subsystem of equipment that processes, transmits, receives, or interchanges data or information.

Dear @Md Asraful Haque, there are many different definitions for information technology (IT). Let me bring some of them here, links follow.

Information Technology is the technology which provides information at any time any where in the world. Computer Technology and Communication Technology Together facilitate to provide the the information. Communication Protocols, DBMS, different applications of the Internet, The Internet and computer processing make Information technology.

Prof. Carlos M. Travieso added this interesting point in private message: The word "engineering" is wider than "technology", it is the key, because the "engineering" develop the "technology".

Think generally Information Technology (IT) is encompassing technology & automation surrounding data & information to focus on the application / usage of IT to collect, process, communicate data & information for better human decision making.  Whereas computer engineering is focusing on the architecting, designing & programming of computer related hardware & software in detailed level.

Not sure there is universal definition on these 2 terms as different people / scholars have slightly different interpretation on these 2 terms.  Hence, the better way to differentiate them is to list down the sub-components / scopes of these 2 terms so that we can compare & contrast them - be it in deciding on which degree to pursue in universities or in evaluating whether a potential job seeker is meeting the job requirement.

Information technology is --- the study or use of computers for storing, retrieving, processing and sending information. Further, it  involves the development, maintenance, and use of computers and software for the processing and distribution of information 

IT (information technology) is the applied science concerned with all aspects of managing & processing information, especially within a large organization or company. IT is wider than computers & networks so IT is generally not used to refer to personal or home computing & networking.

As a broad field, IT actually encompasses all layers of all systems within an organization -- from the physical hardware to the operating systems, applications, databases, storage, servers and more. Telecommunication technologies, including Internet and business phones are also part of an organization's IT infrastructure.

My brother is a computer engineer & I observed that he was more concerned with the hardware than the software in computers (i.e. In simple terms, more on the inner side of the computers rather than the programming or exchange of information).
