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.
Within a central office or data center or in a metropolitan-area network (MAN), 10-Gigabit Ethernet interfaces are commonly used to interconnect routers or other devices. The Cisco 1-Port 10-Gigabit Ethernet LAN/WAN-PHY SPA supports a broad range of customer needs and applications.
