Difference between Wi-Fi and WiMAX 0

Usual ways of Internet access are Dial up, broad band and Wi-Fi. Dial up access may be used for very low speed and data access. They are nowadays not commonly used. Broadband access is commonly used and it is comparatively faster than dial-up. Here the connection is through wires. In Wi-Fi the connection is wireless. Wi-Fi can be used using wifi router or using wifi hotspots.

There are some problems with these internet access technologies. Dial up is very slow and broadband is based on wires.Also, broadband is costly and unreachable in many places.  In wifi the range is very small and it makes limited internet access. So we go for a new technology in internet access  which solves the above problems. That technology is termed as WiMAX.




WiMAX provide high speed internet access without wires and modems. Instead of small wifi coverage, WiMAX provides broad coverage like a mobile phone network. WiMAX is short form of worldwide interoperability for Microwave access. WiMAX could definitely replace cable and DSL services. It will provide internet connection everywhere. When you switch on your Laptops, it will connect to the nearest WiMAX antenna.
WiMAX is similar to Wi-Fi, but the former has high speed, better coverage and can provide service to many people. Wi-Fi access is limited to about 30 m while the WiMAX coverage extends upto 50 km. Wi-Fi have a maximum speed of about 54 megabits per sec. But WiMAX can provide about 70 Megabits per sec.

This is because, Windows installer process is not operated in the safe mode. To uninstall a program in safe mode, we have to edit the registry. Type REGEDIT in the RUN command from start menu. Go to the key, HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\safeboot\minimal. Then right click on the key and select key from New. Then give MSIService as the name. Then double click on it and set the value as Service.


Using this newly created MSIService key you can uninstall programs in safe mode. You can start installer services from the window which is displayed when Services .msc is entered into the Run command.
