Screen Saver - When you are away for a set period of time, your computer runs a program that places images that move so your screen doesn’t get one image “burned” into it. The default screen saver is the Student Services name scrolling across your screen. If you download a free screen saver from the internet, it can cause problems even if you remove it later.
Server vs Mainframe - When you log into your computer in the morning, you are connecting to the DOSSMAIN server. This is the server that has all your programs, personal space (F:\users), group space (G:\) and allows you to be connected to the internet. When you log into QWS secure or MVS, you are connecting to the Mainframe. The Mainframe has most all the student information (WIUP and TSO) and is separate from the server. There can be times when you are connected to one but not the other.
Shortcut - A shortcut is a way to get to a file or program quicker. Usually, these are pictures that you can double click on called icons.
Shutdown - When you click the start button and then select the shutdown option, you are giving several other options to choose from; one of those options is shutdown. If you pick this option, your computer will shutdown and power off.
Start Button - This is the button usually located at the bottom left of your desktop. When you click the start button you will see the recently used programs, pinned programs, all programs, my computer, and my documents.
Switch - This is one of many infrastructures that you don't see. It is connected to your computer via the wall plate in your office.
System Tray - This is the area to the far right of your task bar. It usually has your clock and other programs that load at startup. Some of these programs are ones that load by default for network connection. The more programs you have in this area, the slower your computer will run.
