Answers. Best Answer: 12 hours. Though you can sleep you need to wake up every hour, and doing that is basically the same as getting no sleep. Also, you would need someone else to wake you up every hour and that would disturb their sleep too, so it is easier for everyone if you just stay up the 12 hours.Source(s):Maggie Â· 7 years ago.hough you can sleep you need to wake up every hour, and doing that is basically the same as getting no sleep.

The ping Command. ping is one of the most basic, but also one of the most useful, tools for obtaining information about computer networks, including the Internet.

An example would be open 192.168.1.12. Note: By default, the open command uses the TCP port 21 to make the FTP connection. If a different TCP port is needed for connecting to the domain name or IP address you are using, enter the port number after the domain name or IP address in the open command.Once connected, a username and password prompt will appear.onnect using FTP. To connect to another computer using FTP at the MS-DOS prompt, command line, or Linux shell type FTP and press Enter.
