Unfortunately, when it comes to safety we have no other choices. In electrical industry, fuses are destroyed in order to protect lives or property.

Whenever there is a big fault in power lines, possibly caused by short-circuiting, fuses are very helpful to stop flow of current.

Unlike circuit breakers, fuses have no mechanical moving parts that can fail to operate. A fuse is just an electrical link in circuit that can melt very quickly whenever a certain temperature is reached.

Fuses have 4 things to do in a circuit:

1. They must sense faults 2. They must open quickly when a short-circuit occurs 3. They must also sense normal overloaded conditions, but must open if overload becomes excessive or prolonged. 4. They must not change or alter characteristic of current during normal operation.

Early types of fuses use lead wires, selected based on their diameters, connected to terminals. These types have some disadvantages. Whenever a fuse blows, molten metal spatters over equipment and could cause injury to people or cause fires, especially when arc was not confined.

Over past few years as internet has become more and more popular, privacy has become a major issue. Just as if you are walking down street and can be watched, every click of your mouse every website you browse, or file you download, is traceable. In recent years this has become a major issue.

Spyware: The most currently talked about privacy issue at moment. Spyware are little programmes that can easily be picked up by surfing any website or downloading files. Spyware can pickup information from where you surf to your credit card details, this information then can be sold.

Generally only "Dodgy" websites give you Spyware but people are now creating harmless looking websites with real content but only offering a download that may be Spyware. There are many developers trying to create software that will infiltrate Spyware and take it out, but just as smart these coders are so are Bad guys. Microsoft are waging war on Spyware by developing their own free downloadable Spyware remover, but already in beta stages, viruses have been made to stop Microsoft's Anti-Spyware programme in its tracks. This is lengths these malicious coders will go to, to keep their piece of pie.
