Document Summary

Network operating system (nos): routes and manages communications on the network and coordination network resources. Hubs: simple devices that connect network components, sending a packet of data to all other connected devices. Switch: has more intelligence than a hub and can filter and forward data to a specified destination on the network. Router: communications processor used to route packet of data through different networks, ensuring that the data sent gets to the correct address. Software-defined networking (sdn): new networking approach that many control functions managed by one central program, that can run on inexpensive commodity servers that separate from network devices themselves. Packet switching: method of slicing digital message into parcels called packets, sending packets along different communication path as they become available then reassembling the packets once they arrive at destinations. Protocol: set of rules and procedures governing transmission of information between two points in a network.
