So you have the latest internet security for your computer - anti-virus, firewall, spyware protection, privacy protection, the whole kit and caboodle. Nothing is going to get to your computer network now..... or have you just overlooked one of the most easiest ways to access your computer network.
Wireless networks that have no security enabled is more open than you leaving all your doors and windows open to burglars to get in your house... it's like opening all your doors and windows and then standing in the middle of the street yelling out that all your doors and windows are open for anyone to come in - good or bad.
On the other hand you might have been told that you have security on your wireless network. But to your lack of knowledge and your technician's lack of knowledge he might have only setup WEP security on your wireless router. It might protect you from novice users that try to access your network, but to any hacker that knows a bit more, cracking your WEP security on your wireless router is not a big task at all.
As a home user you might be less of a target but you can still be in the firing line of some hackers that can plant key loggers onto your computer and then record any information you type, including passwords and credit card information. Realistically you'll need to have a person come into range of your wireless network to attempt this, but it's not a hard task - have you ever turned on your laptop and searched and found many networks in your vicinity. You probably found some unsecured network and could connect to those.
As a minimum other people will use your internet connection for surfing the net and downloading who knows what - at your expense!
If you run a business or you have friends or family that run one - it's a very good ideas to send this on!...
If you are not sure if your wireless network is secure (running WPA/WPA2) you can have some one from elscomm come out and make sure that you have the correct security protection for your wireless network. Contact us on (02) 9572 7571 or 0402 936 861 or create a support ticket here |
You've more than likely heard the word "defrag". But what does it mean and should you pay any attention to it. It's hard to pay any attention to it if you have no idea what it is, why you should do it and what benefits are involved. Let's have a look.
"defragmentation (or defragging) is a process that reduces the amount of fragmentation in file systems. It does this by physically reorganizing the contents of the disk in order to store the pieces of each file close together and in order (contiguously)."
"Reading and writing data on a heavily fragmented file system is slowed down as the time needed for the disk heads to move between fragments, and waiting for the disk platter to rotate into position, is increased. For many common operations, the performance bottleneck of the entire computer is the hard disk; thus the desire to process more efficiently encourages defragmentation. Operating system vendors often recommend periodic defragmentation in order to keep disk access speed from degrading over time." - source wikipedia
So it's obvious that regular defragmentation of your hard drive is desirable. You should aim to do this every couple of months, depending on the amount computer usage. Follow the steps below to defrag your hard drive.
1. From your desktop click on the Start button and select Run
2. Type dfrg.msc in the blank field. This will open the Disk Defragmenter window.
3. On the bottom left side of this screen is a button called Defragment. Click on it. The first phase Disk Defragmenter performs is analysing your hard drive to determine whether or not your hard drive needs to be defragmented. If it does it will start the second phase automatically which is to defrag your hard drive. If your hard drive does not need defraging then a message will display so. Try again in a couple of months.
4. When defragmentation has completed put the next run in your calendar so you do not forget.
Well I hope this has increased your knowledge Disk Defragmentation and maintaining your computer in a optimum state. |
