Case study notes

Introduction

A failover is a procedure by which a system automatically transfers control to a duplicate system when it detects a fault or failure. In computing and related technologies such as networking, failover is switching to a redundant or standby computer server, system, hardware component or network upon the failure or abnormal termination of the previously active application,[1] server, system, hardware component, or network. Failover and switchover are essentially the same operation, except that failover is automatic and usually operates without warning, while switchover requires human intervention.

Please write a clear, concise description of your topic here. You will likely reference your introduction from somewhere else. Please use the following syntax at the end of each of your ideas. IT IS CRITICAL YOU ATTRIBUTE others work. Your introduction should be factual. No more than 3 or 4 sentences, please. Because you are not an expert on your topic, I expect you to triangulate your information. LOTS OF LINK TO OTHER RESOURCES PLEASE! If you do not use a section, please delete it.

How does it work or a deeper look

• If you are discussing a THING YOU CAN TOUCH, you must explain how it works, and the parts it is made of. Google around for an "exploded technical diagram" of your thing, maybe like this example of an MRI It is likely you will reference outside links. Please attribute your work.
• If you are discussing a PROCESS OR ABSTRACT CONCEPT (like fuzzy logic) you must deeply explain how it works.

Examples

Please include some example of how your concept is actually used. Your example must include WHERE it is used, and WHAT IS BENEFIT of it being used.

Pictures, diagrams

Pictures and diagrams go a LONG way to helping someone understand a topic. Especially if your topic is a little abstract or complex. Using a picture or diagram is a two part process:

1. upload a file
2. use the file on a wiki page
