WHAT IS A NETWORKING MODEL?
Definition
A networking model, sometimes also called either a networking architecture or networking blueprint, refers to a comprehensive set of documents.
Term
WHEN DID THE OSI MODEL START?
Definition
The International Organization for Standardization (ISO) took on the task to create such a model, starting as early as the late 1970s, beginning work on what would become known as the Open Systems Interconnection (OSI) networking model.
Term
WHEN DID THE TCP/IP MODEL BEGIN?
Definition
A second, less formal effort to create an open, vendor-neutral, public networking model sprouted forth from a U.S. Department of Defense (DoD) contract.

WHAT IS THE TCP/IP NETWORK ACCESS OR NETWORK INTERFACE LAYER?
Definition
Note:
The original TCP/IP model’s link layer has also been referred to as the network access and network interface layer.
Term
WHAT IS THE DIFFERENCE BETWEEN THE TCP/IP ORIGINAL AND UPDATED MODEL?
Definition
To help people understand a networking model, each model breaks the functions into a small number of categories called layers. Each layer includes protocols and standards that relate to that category of functions. TCP/IP actually has two alternative models, as shown in Figure 1-4.

Term
WHAT RFC # BREAKS DOWN TCP/IP INTO LAYERS?
Definition
The model on the left shows the original TCP/IP model listed in RFC 1122, which breaks TCP/IP into four layers. The top two layers focus more on the applications that need to send and receive data. The bottom layer focuses on how to transmit bits over each individual link, with the internet layer focusing on delivering data over the entire path from the original sending computer to the final destination computer.
Term
DESCRIBE THE TCP/IP APPLICATION LAYER?
Definition
TCP/IP application layer protocols provide services to the application software running on a computer. The application layer does not define the application itself, but it defines services that applications need. For example, application protocol HTTP defines how web browsers can pull the contents of a web page from a web server. In short, the application layer provides an interface between software running on a computer and the network itself.
Term
WHAT ARE THE MOST COMMONLY USED TRANSPORT LAYER PROTOCOLS?
Definition
The two most commonly used transport layer protocols are the Transmission Control Protocol (TCP) and the User Datagram Protocol (UDP).
Term
What is a common protocol for TCP/IP NETWORK layer?
Definition
The TCP/IP network layer includes a small number of protocols, but only one major protocol: the Internet Protocol (IP). In fact, the name TCP/IP is simply the names of the two most common protocols (TCP and IP) separated by a /.
Term
WHAT ARE THE 2 TCP/IP VERSIONS OF IP?
Definition
TCP/IP defines two versions of IP: IP Version 4 (IPv4) and IP Version 6 (IPv6). The world still mostly uses IPv4, so this introductory part of the book uses IPv4 for all references to IP. Later in this book, Part VII, “IP Version 6,” discusses this newer version of the IP protocol.
Term

Addresses used to identify a packet’s source and destination host computer. Addressing rules also organize addresses into groups, which greatly assists the routing process.
Term
WHAT IS A IP ROUTING PROTOCOL?
Definition
A protocol that aids routers by dynamically learning about the IP address groups so that a router knows where to route IP packets so that they go to the right destination host.
