reload

1) In computers, to reload is to start a program over again, usually because it has crashed or because it has begun to display aberrant behavior. Programs sometimes begin to behave strangely in use, perhaps because of a programming problem or a conflict with other software. A common reason for some programs, such as word processors, to misbehave is because users inadvertently hit keystrokes that initiate an undesired action. When the program is closed and reopened, settings generally revert to default values and the problem is solved. However, sometimes the problems are caused by entities outside the program, in which case the programming adage "If all else fails, reboot" applies. Reload is also sometimes used to mean reinstall.

2) Using a Web browser, to reload (or refresh) is to download browser content (such as a Web page or other file) that is already displayed. Reloading browser content ensures that the most currently updated information will be shown.
