wireless networking precautions

Wireless networking is something a lot of homes now have. It is important to keep them private and secured. If wireless networking in your home is not secured then people who live close to the wireless networking can look at the online activity that goes on in the wireless network. Other than spying, someone could also get access to the hard drive that the network is hooked up to.
Wireless networking is also not free, people living around the network could steal the connection. Also, if they are doing something illegal, it could be tracked back to the person who owns the wireless network who gets in trouble for something they did not do. Things have become more safer and there should be no reason for a hacker to get into someones wireless network without permission.

Strong Password (how to create and use them)

Everyone who have accounts on the internet, like an email, need to be particular about the way they create their password. Privacy is key to everyone, especially on the internet. If a password is stolen, important information can be stolen. There are a few steps in creating a strong password.
One way is to make a sentence that you will be able to remember, but others could not think of. Use the first letters of every word in that sentence to create the base of your password. To make it stronger, lower case and upper cased letters can be put into your password as well. Make sure your password is long enough for people not tobe able to guess it. Avoid having things such as "123" or "Abc."
