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.
Application binary interface. Linux kernel and GNU C Library define the Linux API. After compilation, the binaries offer an ABI; keeping this ABI stable over a long time is important for ISVs. In computer software, an application binary interface (ABI) is the interface between two program modules, one of which is often a library and/or operating system and the other one is usually an application created by a regular programmer.
