What is Redirection?

[denson]

When the location of a page has been changed, then the site is redirected to inform the search engines that the switch over has happened. This is done using 301 or 302, as the case may be.

The term used to describe the process of sending a signal, data, or other information to an alternate location. Some examples of redirection are sending data intended for one drive to another drive or sending a user visiting a web page to another web page.

When referring to something malicious or when your browser or search is redirecting you to somewhere you don't want to be this is referred to as a Hijack.
