Most college students head off to college these days with a computer. Although a personal computer may not be absolutely necessary since most colleges have computer labs for student use, it is definitely a convenience to have your own computer.
There used to be arguments in favor of laptops and desktop computers, but we’re past that now. Laptops are the way to go for almost all students, and some even use just a tablet. Your student should think carefully about how they plan to use the computer. They should talk to other students who are planning to attend the school, as well as to students currently attending. The college may also have an official recommendation from its technology center.
Check with the college about specific requirements and/or recommendations for computer specifications. They know what has worked best in the past, and what they are able to support. Consider their suggestions carefully. Some colleges may have a plan that provides a discount on computers purchased through them. Your student should also investigate whether the college supports both Mac and Windows operating systems before they make a final choice.
