What is the datagram used at the Transport Layer of the TCP/IP networking model
The datagram is referred to as a segment.
What is the datagram used at the Internet Layer of the TCP/IP networking model.
The datagram is referred to as a Packet.
What is the datagram used at the Network Access Layer of the TCP/IP networking model
The datagram is referred to as a frame.
Which layers of the OSI Model correspond to the Application layer of the TCP/IP model.
Application, Presentation, and Session
Which layer of the OSI model corresponds to the Transport Layer of the TCP/IP model.
The OSI model also has a Transport Layer and it directly corresponds with it's TCP/IP alternative.
Which layer of the OSI model corresponds with the Internet Layer of the TCP/IP model.
Which layers of the OSI model directly correspond with the Network Access layer of the TCP/IP model.

Describe the functions of the OSI Application Layer (layer 7)
Provides an interface between the communications software and any applications that need to communicate outside the computer on which the application resides. Also defines processes for authentication.
Describe the functions of the OSI Presentation Layer (Layer 6).
Defines and negotiates data formats, such as ASCII, EBCDIC, binary, BCD, and JPEG. Encryptions is also defined at this layer.
Describe the functions of the OSI Session Layer (Layer 5)
Defines how to start, control, and end conversations (sessions). This includes the control and mangement of multiple bidirectional messages so that the application can be notified if only some of a series of messages are completed. This allows the presentation layer to have a seemless view of the incoming data stream.
Describe the functions of the OSI Transport Layer (Layer 4).
Focuses on issues related to data deliver to another computer. Error recovery and flow control for instance.
Describe the functions of the OSI Network Layer (Layer 3).
Defines three main features: Logical addressing, routing, and path determination.
Describe the functions of the OSI Data Link Layer (Layer 2).
Defines the protocols that determine when a device can send data over a particular medium. They also define the format of a header and trailer that allows devices attached to the medium to send and receive data successfully. The data link trailer, which follows the encapsulated data, typically defines a frame check sequence field, which allows the receiving device to detect transmission errors.
Describe the functions of the OSI Physical Layer (Layer 1).
Refers to the standards from other organizations that deal with the physical characteristics of the transmission of medium, including connectors, pins, use of pins, electrical currents, encoding, light modulation, and the rules for how to activate and deactivate the use of a physical medium.
List all seven layers of the OSI model.
Physical, Data Link, Network, Transport, Session, Presentation, Application.
Please do not throw sausage pizza away.
List the benefits of a layered protocol specification.
Less Complex - Breaks the concepts up into smaller parts.
Standard Interfaces - Allows for multiple vendors to create competing products to be used for a given function.
Easier to Learn
Easier to Develop - Reduced complexity allows easier program changes and faster product development.
