When found third in a codon of RNA, cytosine is synonymous with uracil, as they are interchangeable as the third base. When found as the second base in a codon, the third is always interchangeable. For example, UCU, UCC, UCA and UCG are all serine, regardless of the third base.hen found third in a codon of RNA, cytosine is synonymous with uracil, as they are interchangeable as the third base.

bridgeds: br0, br-lan. are used to make multiple virtual or physical network interfaces act as if they were just one network interface (quasi the opposite of VLANs). Can also be used for VPN and bridged interfaces. The Linux Ethernet bridge can be used for connecting multiple Ethernet devices together.
Linux, really a child of the Internet, offers all the necessary networking tools and features for integration into all types of network structures. An introduction into the customary Linux protocol, TCP/IP, follows. The various services and special features of this protocol are discussed.
