TCP/IP TRANSPORT LAYER PROTOCOLS
 - UDP AND TCP



TCP/IP DATA LINK LAYERS PROTOCOLS - ETHERNET AND POINT TO POINT PROTOCOL
[As per the OSI model, Ethernet provides services up to and including the data link layer.]

THE PROCESS OF HTTP ASKING TCP TO SEND SOME DATA AND MAKING SURE THAT IT RECEIVED CORRECTLY IS AN EXAMPLE OF WHAT?
ADJACENT-LAYER INTERACTION


THE PROCESS OF TCP ON ONE COMPUTER MARKING A TCP SEGMENT AS SEGMENT 1, AND THE RECEIVING COMPUTER THEN ACKNOWLEDGING THE RECEIPT OF TCP SEGMENT 1 IS AN EXAMPLE OF WHAT? 
SAME-LAYER ENCAPSULATION


The process of a web server adding a TCP header to the contents of a web page, followed by adding an IP header and then adding a data link header and trailer is an example of what?
DATA ENCAPSULATION

Which of the following terms is used specifically to identify the entity created when encapsulating data inside DATA link layer headers and trailers?

FRAME


Which OSI layer defines the functions of logical network-wide addressing and routing?
LAYER 3



Which OSI layer defines the standards for cabling and connectors?
LAYER 1


WHAT RFC # BREAKS DOWN TCP/IP INTO LAYERS?

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.




DESCRIBE THE TCP/IP APPLICATION LAYER?

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.



WHAT ARE THE MOST COMMONLY USED TRANSPORT LAYER PROTOCOLS?

The two most commonly used transport layer protocols are the Transmission Control Protocol (TCP) and the User Datagram Protocol (UDP).



What is a common protocol for TCP/IP NETWORK layer?


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 /.



WHAT ARE THE 2 TCP/IP VERSIONS OF IP?

 IP Version 4 (IPv4) and IP Version 6 (IPv6).
