Bridging is the process of transparently connecting two networks segments together, so that packets can pass between the two as if they were a single logical network. Bridging is performed on the data link layer; hence it is independent of the network protocol being used - it doesn't matter if you use IP, Appletalk, Netware or any other protocol, as the bridge operates upon the raw ethernet packets.read more.
Traditionally, Unix/Linux/POSIX filenames can be almost any sequence of bytes, and their meaning is unassigned. The only real rules are that "/" is always the directory separator, and that filenames can't contain byte 0 (because this is the terminator). Although this is flexible, this creates many unnecessary problems. In particular, this lack of limitations makes it unnecessarily difficult to write correct programs (enabling many security flaws), makes it impossible to consistently and accurately display filenames, causes portability problems, and confuses users. more ....
