Wireles Technology’s

We want stay connected, no matter where we are. Wireless network communication makes this possible.

Wireless technologies use electromagnetic waves to carry information between devices. An electromagnetic wave is the same medium that carries radio signals through the air.

Examples of Wireless Devices:

  • Infrared is a device that we normally use & it is relatively low energy and cannot penetrate through walls or other obstacles.

  • Radio Frequency (RF) is a device that we are not much familiar, Its an advanced device & RF waves can penetrate through walls and other obstacles, allowing a much greater range than IR.

  • Wireless technology offers many advantages compared to traditional wired networks. One of the main advantages is the ability to provide anytime, anywhere connectivity. Wireless technology is fairly easy and inexpensive to install. The cost of home and business wireless devices continues to decrease.

Benefits of Wireless LAN Technology:

  • Mobility allows for easy connection of both stationary & mobile clients.

  • Flexibility provides anytime, anywhere connectivity.

  • Cost Savings Equipment costs continue to fall as the technology matures.

  • Reduce installation time installation of a single piece of equipment can provide connectivity for a large number of people.

Types of Wireless Networks:

  • WPAN is the smallest wireless network used to connect various peripheral devices such as mouse, keyboards and PDAs to a computer. All of these devices are dedicated to a single host with usually use IR or Bluetooth technology.

  • WLAN is typically used to extend the boundaries of the local wired network (LAN). WLANs use RF technology and conform to the IEEE 802.11 standards. They allow many users to connect to a wired network through a device known as an Access Point (AP). An Access Point provides a connection between wireless hosts and hosts on an Ethernet wired network.

  • WWAN networks provide coverage over extremely large areas. A good example of a WWAN is the cell phone network. These networks use technologies such as Code Division Multiple Access (CDMA) or Global System for Mobile Communication (GSM) and are often regulated by government agencies.

XP or Vista?

Things have been changed now. Microsoft is going to launch another new operating system next year, known as Windows 7, Beta is out now.

Computer Resellers in Male’ was Installing XP on the system’s they sell. But some of the Resellers are now Installing Vista, on the systems they sell. Windows XP is going down, Ratings & Popularity.

In my view Windows XP is unique on It’s own way and Windows Vista & Windows 7 Styles are almost same, Windows XP Style is totally different, It haven’t been used in any other, (Windows 98, 200) or any other.

I guess most of the Maldivians still use Windows XP. Some people try Windows Vista & go back to XP. I guess some peoplez wanna try Vista because Its new. Vista is gone now, I didnt mean its dead. But now Its the time for new OS, Windows 7. Still XP is leading in Maldives. Mostly Vista are found in Laptops. Windows XP are still being used in Offices, Schools & Homes.

Many people says that Windows XP is dead now. But I totally disagree with that, XP is still Alive, Most of the people in Maldives still use XP.

Cheerz.. I wrote this post because some of my friends said that Windows XP is dead & It sucks a big time. I use Windows XP on my home Desktop Computer, Friends saw XP on my system & told me to Format & Install Vista.

Important System Tools in Windows Vista

In this post I’ll tell you about some important & useful System Tools in Windows Vista. Those tools can help you to keep your system in a good health.

Disk Cleanup
Go to Start / Accessories / System Tools & You will see Disk Cleanup. You can clean unwanted files in C Drive. Mostly Error Report Data, Browser Cache, Offline Pages etc.. Recently I cleaned 4GB from C Drive using This.

Disk Defregmenter
This is a Tool that rearranges fragments in your Hard Disk. Go to Start / Accessories / System Tools & You will see Disk Defregmenter. There are special Deregmenter softwares. If you don’t know a good one to use I strongly recommend to use this Windows one.

System Restore
How do you know that your computer might not crash tomorrow? Nobody know what’s gonna happen tomorrow. I recommend you to create a Check Point in System Restore every night before you sleep. When your System crashes, You can simple restore to latest check point which you have created. I know most of the Maldivians are lazy, but this is a useful one.

Error Checking
This tool fix simple errors on hard disk & fix bad sectors. Click Properties of your hard drive & go to Tools tab, You will see Error Checking. Use the tool twice a Week.
