Wireless versus Ethernet networks

In recent years, ethernet hasnt exactly been fashionable. People are sick of running long wires all over the place, making holes in their walls, and being restricted when it comes to where they can use their computer. wireless networking has become all the rage and some predict that it will have killed off ethernet altogether within a few years.

wireless networking works by transmitting radio waves through the air. While it isnt yet strong enough to provide networking for a large area, it is quite possible and cheap to set up a cheap wireless networking system large enough to cover an entire house, using nothing more than a wireless router and a wireless card in each computer you want to use on the network. Newer laptops even come with wireless capabilities completely integrated in the form of Intel Centrino, so you can easily connect to wireless networks wherever you go.

Of course, wireless also has its fair share of downsides. Sure, ethernet requires ugly wires strewn all over the place, but its also much faster, more stable and more reliable. For large businesses or small businesses that have already had all the wires hidden away in their walls, there is little reason to change over to wireless now. ethernet is also often more secure wireless networks are often left unsecured, meaning that anyone can drive past and connect to them. While ethernet networks can be insecure as well, the network intruder at least has to be inside the building in most cases, not sitting in a car outside.

In turn, wireless networking removes a lot of niggles from ethernet. The best thing is that you no longer have to worry about wires getting damaged somehow and needing to be tracked down for replacement. Ultimately, which one you use will depend on how adventurous you are, and exactly what you plan to do with your network.

What is Cadence?

When cyclists talk about cadence they are referring to the number of revolutions that they crank makes each minute as the pedals are turned. This in laymans terms simply is the speed at which the cyclist pedals or turns the pedals on the bike as they ride.

Most cyclists will have a certain cadence speed which they feel comfortable with when they are out riding. Today a lot of bicycles come with a large number of gears so it makes it possible for a cyclist to stick to a cadence that they prefer through a wide range of different speeds at which they are traveling. Normally a typical cyclist will look at having a cadence of between 60 and 80 revs per minute (rpm), whilst professional (racing) cyclists will look at theirs being between 80 and 120 rpm. However sprint cyclists will normally be able to manage 170 rpm for very short distances. Lance Armstrong one of the worlds well known professional cyclists is able to produce a cadence of 120 rpm.

However there are many cyclists that believe one form of cadence is much more efficient than another. but the actual cadence that is preferred by each rider is completely different. Yet with racing cyclists the differences in their preferred cadences are very small compared to those people who just enjoy cycling for pleasure rather than as a competitive sport.

What is important to note that each cyclist will have his own particular range of cadences that he prefers and are much smaller than the general ranges which have been previously listed above? but what their preferred cadences are will actually influence the number as well as the range of gears that they have on their bicycle and which they feel are appropriate for the conditions in which they ride.

Today there are many companys who produce devices for measuring the cadence on a persons bicycle such as the Vetta V100 wireless cadence kit. These small computers are mounted on to the handlebars of the users bicycle and then a small magnet is placed close to the pedal sprocket. Then as the rider is out cycling or competing in a race they will see on the small computer screen (which is mounted to the handlebars) displays their cadence information.
