These are Computer Science, Computer Engineering and Information Technology.
Many people try to understand the differences by asking what kinds of jobs graduates get.
Unfortunately, you cannot differentiate these degrees by job duties. The problem is that we cannot even guess what the jobs will be in four years, or even two years. What is common among them is that each prepares you for the Information Technology job market. How they differ is in the way they are packaged, especially in the non-CS courses that you must take. In Computer Science, you are getting a traditional science degree.
