Language Tools

I was informed of some of these tools in unsolicited emails to ‘admin’. The sender had to be human and not a robot to have understood site structure. Use at your own risk. The sites have no ‘about’ information. The first thing I ask myself when I encounter any new site or product is “How do they make their money?” since everything has a cost including this site (I don’t make any money as I write this).

Your PC Information

This could be a vast area for Windows users like myself. I’ve decided to document solutions to my problems to help me and possibly you in the Future.

MAC Address

The solution to finding this provides a lot more information that a techie might need. If you were a DOS user of the 1980’s you use to a command line interface (pre-Windows) you may be surprised that the latest Windows still has DOS in its core.

Right-click on the Start menu under the 4-pane window icon. Find the “Run” option and left-click. Enter the string “cmd”, short for command. You are now at a command line prompt. Enter “ipconfig/all”. Under “Ethernet adapter Ethernet:”. Find the line “Physical Address. . . . . . . . . : XX- XX – XX – XX – XX – XX ” where “XX” may be any combination of numeric or upper-case alphabetic characters. That’s your system’s MAC address.
