1. Buffer - Contains data that is stored for a short amount of time, typically in the computer's memory. Buffering is used to improve several areas of a computer's performance. Without buffers, computers would be a lot slower, and a lot less efficient.
2. Trojan Horse - Like the story in Greek mythology, a Trojan horse is accepted, like a gift, into your computer, and when you activate the file or program, it attacks your computer. Trojan horses can come in various forms: games, programs, and files. To prevent this virus from affecting your computer, scan your computer with an anti-virus program frequently.
3. LAN (Local Area Network) - A computer network limited to a small area, for example, your house. Businesses use this mainly to share information. A LAN is run from your network connection.
Every Friday we will be posting the "Technical Terms of the Week." It is our hope that over time, you will be able to better understand the technical terms of the computer world.

How to keep your wireless network from being hacked
Wireless networks are not near as secure and encrypted as a traditional wired network. This is because a wireless network can be accessed anywhere in its broadcasting area. This means that a wireless network has more vulnerability to be hacked. Hackers can do terrible things to your computer, such as implant viruses, worms, spyware, malware, adware, and weird pop ups. They can even make your computer quit working altogether.
To prevent this from happening, make your wireless network as secure as possible. Following are a few possible options to make your wireless network as secure as possible:
- Antenna Placement - Set your wireless access point, or router as far away from a window as possible, if possible. The best place for a wireless device is in the central (middle) location of a building.
- Set the Security High - Most wireless devices come with security. Whether it be WEP, WPA, WPA2, or Radius, any security is better than no security. I would recommend always having security on your network; never go without it.
- Disable DHCP - Basically, DHCP is the automatic assigning of protocols, or "numbers." By disabling this, the hacker will have to find the correct protocols in order to hack your network. This will take the hacker a very long time.
- Hide your SSID - Standing for Service Set Identifier, SSID is the name of your wireless network. By disabling this, the hacker will have to manually enter your SSID.

Windows 7 vs. Windows Vista
On October 22, 2009, Microsoft released Windows 7, the successor of the joke-of-an-operating-system, Windows Vista. Some may disagree, and as a matter of fact, I disagree, but I did agree when Vista first came out. After three some years as a Windows Vista user, I became quiet acquainted with it.
Now a Windows 7 user, I've moved more over to its side, rather than Vista's. Here's some reasons why:
- Windows 7 had little (to no) bugs that needed fixing, whereas Windows Vista didn't run smoothly until mid-2008, over a year after it was released.
- Windows 7 has a much more friendly-user interface. Windows Vista needed twice the configuration that both Windows XP and Windows 7 needed to personalize it to your liking.
- Windows 7 is evolution. Windows Vista is revolution.
However, Windows Vista did have a few pros:
- Windows Vista had a new design, much better than Windows XP's.
- Windows Vista (like all other OS's) came with a wider range of hardware support.
- (After a year or so) Windows Vista became more popular than Windows XP.
