Most online master's programs provide technology guidelines for students, which you can compare with your laptop or desktop computer to assess the situation. Your browser or operating system may need updating, or you might just need a few software upgrades or the latest version of apps you will use regularly. You can also add a tablet or another device to the mix to help bridge any technology gaps.
The goal is that your courses run smoothly when you access them, whatever technology setup you have. Many education deals and discounts are available to students who want to invest in a new computer or tablet too, if you feel that a fresh start will be the best option.
The Center for Instructional Development and Technology at SOSU provides a number of student resources that can help you determine whether your current setup will work for online courses at the university. In addition to system requirements for computers, you'll also find Android and iOS guidelines for mobile devices.
