​TCP connections are established through a(n) ____________________, which is the combination of an IP address and a port number.

IP accepts messages called ____ from Transport-layer protocols and forwards them to their destination.

The 32-bit addresses for an IP node are defined in Internet Protocol version 6 (IPv6).

The ____ layer forwards messages to their correct destinations.

​10 Gigabit Ethernet is based on the 802.3ae (2002) and the 802.3ak (2004) standards.

The procedure for forwarding a message between two end nodes in the same LAN depends on the ____________________ network topology.

​Mesh topology is practical for all but very small networks.

​The characteristics differentiating the physical topologies include the length and routing of network cable, type of node connections, data transfer performance, susceptibility of the network to failure, and cost.

​The ____________________ layer establishes and manages communication sessions.

​____________________ is the physical placement of cables and device connections to these cables.

A wireless ____ connects a wireless network to a wired network.

​____ make forwarding decisions by using layer 3 addresses.

​A ____ intelligently forwards messages between two or more networks.

A ____ connects all LAN central nodes in a group of buildings.

____ is the glue that binds private networks together to form the Internet and the World Wide Web.
