Link Layer
The _____ layer provides tools for programs to use to access the network and the lower layers. HTTP, FTP, SMTP, and POP3 are all examples of protocols that operate at this layer.
The _____ layer defines hardware connections and turns binary into physical pulses. Repeaters and hubs operate at this layer.
A NIC may send a _____ onto the network to ask for a MAC Address.
An IP address is known as a _____ to distinguish it from the physical address, the MAC address of the MAC.
Logical Address
A charge on the wire of a NIC is one and a no charge is a _____.
A mathematical method that is used to check for errors in long streams of transmitted data with high accuracy.
Cyclic Redundancy Check (CRC)
A ______ is basically a container for a chunk of data moving across a network.
The TCP/IP model is a _____ model.
_____ connectes each of the subnets via IP addresses instead of MAC addresses.
The _____ serves as the interface between the PC and the network.
Each interdependent network in a TCP/IP internetwork.
UDP also gets data from the Applicaton layer programs and adds port and sequencing numbers to create a container called a UDP _____.
Large networks need a _____ addressing method.
The first 24 bits of a MAC address, assigned to the NIC manufacturer by the IEEE.
Organizationally Unique Identifier (OUI)
TCP _____ have many other fields that ensure the data gets to its destination in good order.
This cable, known in the networking industry as _____, usually contains four pairs of wires that can transmit and receive data.
The _____ layer manages connections between machines. NetBIOS and Sockets operate at this layer.
Basic component of communication over a network.
The _____ layer, which can also manage data encryption hides the differences among various types of computer systems.

The _____ handles this part of networking connecting applications to applications.
Session Software
The _____ layer breaks data down into manageable chunks. TCP, UDP, SPX, and NetBEUI operate at this layer.
The OSI seven-layer model is the _____ model.
Uses a type of binary math called cyclic redundancy check that the receiving NIC uses to verify that the data arrived intact.
