The Importance of a Computer Checkup
What do you do when you are sick? You seek medical consultation and look for a doctor right? What happens if our computer becomes 'sick', is there really such a thing as a computer doctor? Surprisingly, there is! Computer diagnostics software is the equivalent of doctors and can provide for regular maintenance and can even look into the causes of the computer's problems. They can determine the true problem at hand and then provide you a solution to solve that very problem. No matter is it performance issues or loss of data, the computer diagnostics software is there to help you understand how your computer works and how to maintain it.
How important the diagnostic software are is not debatable as it can help you prevent major system errors to do with your computer before they fatally occur. If you are a person who experiences regular system instability, where you often see the blue error screens or having to reboot as it froze, it is time to pick up a computer diagnostics software ad identify your problems. The diagnostic software will start to run tests in your computer as soon as you start it and it will run by itself in the background quietly before returning a complete report of all the tasks it has done. More popular diagnostics software includes those from Symantec, TouchStone Software, TuneUp Utilities, or Network Associates software.
Sometimes, we do not really know all the useless junk that we keep in our computer until we do a thorough computer checkup ourselves. Not many people are aware of a part of your computer named the registry where both important and useless information are kept. Important information pertaining to the login users' details and which applications are allowed to access the computer are all kept here. However, viruses or time may have caused the files to become corrupted and some even have gone missing. Furthermore, false entries are made into the registries slowing down the computer even more as it has to go around those false entries to get to the right ones. Clearing your registry can be done both manually and with the help of PC diagnostic applications.
One of the most troublesome but important tasks to do is to do disk de-fragmentation. This usually takes hours as our hard drives are so large. However, de-fragmentation is essential as it tidies up the data stored in your computer and arranges it in such a way whereby all the memory is utilized properly and efficiently.
It is not a must for you to have regular computer checkups especially since computers are machines and not living and have no need for such delicate care. However, if it is not properly maintained, the chances of it being spoilt is much greater and it usually costs more to buy an entire new computer set than to maintain the old one through regular checks. It is your choice, but for those who do not wish to burn their pockets, computer checks are the way to go.

Applications for Cat5e Cables
When selecting the cable that you are going to be using for your particular applications it is imperative that you choose the correct cable for optimal efficiency. There are several types of cable to choose from and each type has its own particular applications and specifications, so learning to select the right type of cable for your specific exact needs is imperative for an optimally functioning system.
One type of cable commonly known as Category 5e cable is actually an upgraded version of category 5 cable that adds specifications for far end cross talk. In 2001 it was defined formally in the TIA/EIA-568-B standard, however it no longer recognizes the original specification of category 5 cable.
Category 5e cable is the perfect choice for use with 1000BASE-T in spit of the fact that 1000BASE-T was originally designed for use with category 5 cable. The reasons for its being the optimal choice in this application is the tighter specs associated with category 5e connectors and cable.
In spite of the fact that it Category 5e does have a higher level of performance specifications, it will not allow for greater cable distances for Ethernet networks due to the fact that the cables are still confined to 100 meter lengths. The standard or normal practice however; is to limit horizontal or "fixed" cables to a maximum length of 90 meters, which will allow for 5 meters of patch cable on each end of the fixed cable.
For further information on Category 5e cable you can information on its test methods and characteristics defined in in TIA/EIA-568-B.2-2001. It is imperative that you select the correct cable for your particular applications for optimal operating efficiency.
