“Computer Science” is an umbrella term which encompasses four major areas of computing: theory, algorithms, programming languages, and architecture. At the undergraduate level, programs usually cover a broad range of computing topics and allow students to engage in projects across multiple areas. For graduate studies in computer science, it is typical to focus on one area. Therefore, it is important to research the graduate program to make sure that the school has the faculty and resources that you need to complete your master's or doctoral project. While Carnegie Mellon has remained the vanguard over the decades, many schools you might not be that familiar with also have great Computer Science programs, including state schools like Rutgers, University of Texas at Austin, and University of Maryland at College Park.
“Computer Engineering” typically focuses specifically on computer hardware and software. It is an integration of computer science and electrical engineering. For this reason, many people who want to become computer engineers earn an undergraduate degree in electrical engineering (often with a minor or double major in computer science), and then earn a graduate degree in computer engineering. When searching for a graduate program, look for schools that are equally strong in computer science and engineering. MIT is still the leader here, but other schools like the University of Washington and Texas A&M University have built on their strong engineering programs to integrate computer science. Florida Institute of Technology (FIT) has its roots in engineering and has been producing technological advances in computing since its inception. This is reflected in FIT's Electrical and Computer Engineering
Engineering in Information Technology :
Engineering in information technology deals with the study of designing , development , implementation , support or management of computer-based information systems, particularly software applications and computer hardware.
It involves the use of electronic computers and computer software to convert , store , protect , process , transmit and securely retrieve information
