Wireless, or WiFi, technology is another way of connecting your computer to the network using radio frequency and no network cables.

Wireless works similarly to cordless phones; they transmit data from one point to another through radio signals. But wireless technology also requires that you be within the wireless network range area to be able to connect your computer.

• Wireless Local Area Network (WLAN): WLAN are wireless networks that use radio waves. The backbone network usually uses cables, with one or more wireless access points connecting the wireless users to the wired network. The range of a WLAN can be anywhere from a single room to an entire campus.
• Wireless Personal Area Network (WPAN): WPANs are short-range networks that use Bluetooth technology. They are commonly used to interconnect compatible devices near a central location, such as a desk. A WPAN has a typical range of about 30 feet.
• Wireless Wide Area Networks (WWAN): WWANs are created through the use of mobile phone signals typically provided and maintained by specific mobile phone (cellular) service providers. WWANs can provide a way to stay connected even when away from other forms of network access. Also, be aware that additional charges are often associated with the usage of WWANs in some locations.

When working wirelessly from hotspots and public places, you are responsible for ensuring the security of your files and your mobile PC.

To make network access easier for their users, public hotspots typically leave all security turned off. This means that any information you send from a hotspot is most likely unencrypted, and anyone within range of the wireless LAN whether at a next table or in the parking lot can access and use your Internet connection, and look at your unprotected information.

WiFi gives you the freedom to go anywhere and still be connected to your office, your family, and other important aspects of your life. Your virtual office can now be a ice cream parlor in a seaside resort. Embrace and enjoy the flexibility that WiFi affords you.

Microsoft’s newest operating system is called Windows 7 and has just recently been out for a month now. In light of this, CompTech Care takes a look at 4 fantastic New Features in Windows 7. These features may make you rethink and may make you get the next ‘must get’ operating system for your desktop pc or notebook computer.

Feature 1: TASK BAR

At first look and one of the most obvious and noticeable feature is the task bar. The task bar has larger pinned icons that quickly and easily navigate through the various tasks being done; Windows 7 makes the old Quick Launch a much more distant memory. Microsoft made Windows 7 so you can change around the programs order, get full screen previews and even pin more of your favorite programs directly to it. Right- click on any of the icons, and you get a ‘Jump list’ that shows recent files. We think this is a great little feature and can easily speed up productivity by up to 50%. Windows 7 makes navigating downright fun and fast.

Feature 2: NETWORKING

Cool and easy feature with Windows 7. With windows 7, setting up a home network turns literally into a easy and no-brainer. Setting up a home network that actually worked well in older versions of windows sometimes was not something that the non-techie person would try to attempt, but the Windows 7 HomeGroup feature make it a down right sin NOT to set up all your PCs with a home network. Not only do you get the essential files shared like photos, music, videos and documents, but you can literally make one of you PCs a multimedia hub to stream entertainment to other PCs on your network. Amazingly enough, you can also get access to all your media using ‘remote media streaming’. For HomeGroup functionality as well as remote media streaming, all your computers do need to be running Windows 7 but really you’d want to because it is that slick and easy to do.

Feature 3: Better, Bigger, faster, Stronger

One of the big gripes about Windows Vista was that it needed A LOT of horsepower behind it to really run effectively. With Windows 7, you not only get vastly improved boot up times, but you get snappier program response, better recover from sleep time and faster shut down time. All around Windows 7 is leaner, meaner and just that much better than all other versions of Windows before it. It basically does more with what you have (there’s even a version of Windows 7 for cheaper netbooks). With laptops, because of Windows 7′s better power management and its very cool location aware printing features (it switched default printers between the home and office), Windows 7 will quickly become your operating system of choice. Believe me, if you’re a Windows XP holdout, Windows 7 will quickly make you a convert!

Feature 4: Handling Devices and Printers

Microsoft looked for a way to improve its handling of devices and in Windows 7 it has hit a home run. Cell phones, digital cameras, music players, printers old and new, even your PC – Windows 7 has made one easy place to manage all your device.
