How to install Telnet with only one command

 Starting with Windows Vista, Microsoft no longer includes the telnet command installed by default.  It is still available but must be installed or enabled by the user.  The normal way to enabled additional features is through the “Turn Windows features on or off” window found in Control Panel.  This accomplishes the task but can be annoying when you are working in Command Prompt and need to use the telnet command right away.

Instead of going to Control Panel, there is a better way.  At an administrative level command prompt, simply run:

dism /online /Enable-Feature /FeatureName:TelnetClient

Telnet will be available immediately after the dism command has completed running.

What is the big deal about 802.11n?

TechRepublic.com reports: "802.11n is being touted as the networking standard that will unwire the network world. Most people are not convinced, yet curious to see how one defends such a claim. The 802.11n standard has two top-level mandates (unwiring the world not being one of them): Achieve higher data rates and retain backward compatibility with legacy 802.11a/b/g devices. The significance of requiring backward compatibility shouldn’t be taken lightly since it complicates the development process exponentially. Yet the 802.11n group has come up with a soon-to-be-ratified standard that meets both objectives."

This is probably the best article that I have read to date on the 802.11n standard. It appears to be most complex and featured pack of all the 802.11 specifications released so far.
