The Japanese concur with this decision. Ports to other architectures are underway. The Linux kernel is distributed under the GNU General Public License, which basically means that one may freely copy, change and distribute it, but that you may not impose any restrictions on further distribution, and that you must make the source code available. Users would need to only master one operating system, one analysis system, and their associated utilities and programming languages. NFS consists of clients and servers.
Ethernet is a type of network cabling and signaling specification.
There are different physical types of Ethernet. The 10 in 10baseT refers to the signaling speed, while the T means twisted pair. 10baseT offers a flexible topology, high reliability, and is suitable for noisy environments. For instance, since 10baseT uses differential signaling to pick signals off the wire, any interference from nearby power lines will usually affect all pairs equally. Anything that is not canceled out by the twists in the UTP should be ignored by the receiving network interface.
