A client-server network is defined by a well-defined central server that provides numerous services, including centralized authentication. 

_________________________   are used at the Data Link layer to encapsulate packets handed down from the Network layer for transmission on a type of physical media access.

__________________________  are used when you need to convert from one type of cabling to another type. This might be required to convert from one type of fiber to another or from Ethernet to fiber.

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

____________  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,

Every machine on the network must know which part of the host address will be used as the subnet address. This is accomplished by assigning a__________________.

Your network is connected to the Internet. As the network administrator, you install packet filtering on the router that connects your network to the Internet. After you configure packet filtering, users on the network are no longer able to send email outbound to the Internet. What did you do to create this problem? 

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.

_____________________ allows us to have both our analog voice and digital data carried on the same network cable or physical medium. It sends multiple frequencies of different signals down the same wire at the same time.

The _________topology consists of two distinct and terminated ends, with each of its computers connecting to one unbroken cable running its entire length.
