Regarding the time the brain scan itself takes: it is usually 45 to 50 minutes. The scan is of the entire brain not just the IAC's. The contrast is administered IV for the latter part of the scan when the IAC's are checked. There is no meaning attached to the time the scan requires.
What is Ether? Ether is a necessary element -- a fuel -- for operating the distributed application platform Ethereum. It is a form of payment made by the clients of the platform to the machines executing the requested operations.
EtherChannel allows you to achieve greater speed by bundling Fast Ethernet or Gigabit Ethernet links, which makes a switch or router use the merged ports as a single port. This gives you the most bang for your buck from your port cost. EtherChannel uses a Cisco-proprietary hashing algorithm to achieve this link bonding. EtherChannel can be configured on many different switch platforms such as the 6500/6000, 5500/5000, 4500/4000, and 2950/2960 series. In this article, I'm going to focus on how to configure EtherChannel on the 2950/2960 line of switches because those are some of the most deployed and well-known platforms.
