A major in computer science allows you to learn the ins and outs of computers, as well as how to write computer code. These majors usually allow you to work in computer coding or computer building. You might create programs, design major computer elements or work in jobs where you repair or service computers.
Computer programming is a more in-depth degree where you write specific computer programs. During your degree program, you can learn how to write computer programs, use specific codes and develop new programs and software. Usually, your career is in software development, or in working with the actual programming that makes computers run.
If you major in marketing and sales, you can work in another field of computers, which is the advertising and selling of the products. Companies like Apple or Microsoft may hire you to work in their marketing and sales divisions. Although you won't actually have your hands inside of computers for these careers, you are working alongside the designers and developers to sell products; you also may do market research to come up with new ideas that could also be popular.
Majoring in web design and development guarantees that you'll spend your career working with computers. During your degree program, you learn about specific ways to develop and design web sites. Then, in your job, you build these sites and provide support for your customers.
