In the modern era of computing, it's all about connectivity, and Knoppix helps make things easy. Whether it's controlling other machines or letting other machines control it, using FTP or its vastly more secure brethren SFTP and SCP, logging in and running commands with SSH, sharing files and printers with Samba and NFS, or even serving up Web pages with Apache, Knoppix is ready and able to do the hard work that makes your life easier.
This is important stuff, and it's the base for a lot of later information about data recovery, so make sure you take some time to really familiarize yourself with the various options that Knoppix makes available to you for connecting to other machines and resources. You won't regret it — and it may just save your bacon down the road.
