The __________________________ provides the physical transmission of the data and handles error notification, network topology, and flow control.

________________________________________topology consists of a succession of connections between an interface on one router and multiple destination routers—one point of connection to multiple points of connections.

_____________   is usually restricted to spanning a particular geographic location such as an office building, a single department within a corporate office, or even a home office.

An _________   header tells the Data Link layer what to do with a packet once a frame is received.

The _______________________________(NIC) is installed in your computer to connect, or interface, your computer to the network. It provides the physical, electrical, and electronic connections to the network media. 

IP address _________________,   allows you to take one larger network and break it into a bunch of smaller networks.

________________________________  (ping) Uses an Internet Control Message Protocol (ICMP) echo request and replies to test if a host IP stack is initialized and alive on the network.

____________  are comprised of high-capacity storage devices that are connected by a high-speed private network ,separate from the LAN, using a storage-specific switch,

A_________________(a map of the internetwork) describes how to find the remote networks. If a network is directly connected, then the router already knows how to get to it.

In ________________________, a protocol on one router communicates with the same protocol running on neighbor routers. The routers then update each other about all the networks they know about and place this information into the routing table.
