Chapter 5 Vocab - Fundamentals Of Tcp/ip: Transport And Applications

Front 1

connection establishment

Back 1

The process by which a connection-oriented protocol creates a connection. With TCP, a connection is established by a three-way transmission of TCP segments

(Wendell, 2013 Sect. Glossary)

Front 2

error detection

Back 2

The process of discovering whether a data link level frame was changed during transmission. This process is typically uses a Frame Check Sequence (FCS) field in the data link trailer.

(Wendell, 2013 Sect. Glossary)

Front 3

error recovery

Back 3

The process of noticing when some transmitted data was not successfully received and resending the data until it is successfully received.

(Wendell, 2013 Sect. Glossary)

Front 4

flow control

Back 4

Flow Control

The process of regulating the amount of data sent by sending computer toward a receiving computer, several flow control mechanisms exist, including TCP flow control, which uses windowing.

(Wendell, 2013 Sect. Glossary)

Front 5

forward acknowledgment

Back 5

A process used by protocols that do error recovery, in which the number that acknowledges data lists the next data that should be sent, not the last data that was successfully received.

(Wendell, 2013 Sect. Glossary)

Front 6

HTTP

Back 6

Hypertext Transfer Protocol

The protocol used by web browsers and web servers to transfer files, such as text and graphic files

(Wendell, 2013 Sect. Glossary)

Front 7

Ordered Data Transfer

Back 7

A pawnbroking function, included in TCP, in which the protocol defines how the sending host should number the data transmitted, devine how the receiving device should attempt to reorder the data as it arries out of order, and specifies to discard the data, if it cannot be delivered in order

(Wendell, 2013 Sect. Glossary)

Front 8

Port

Back 8

In TCP and UDP, a number that is used to uniquely identify the application process that either sent (source port) or should receive (destination port) data. In LAN switching, another term for switch interface.

(Wendell, 2013 Sect. Glossary)

Front 9

Segment

Back 9

In TCP, a term used to describe a TCP header and its encapsulated data (also called a L4PDU). Also in TCP, the process of accepting large chunk of data from the application layer and breaking it into smaller pieces that fit into TCP segments. In Ethernet, a segment is either a single Ethernet cable or a single collision domain (no matter how many cables are used)

(Wendell, 2013 Sect. Glossary)

Front 10

sliding windows

Back 10

For protocols such as TCP that allow the receiving device to dictate the amount of data the sender can send before receiving an acknowledgment-a concept called a windoe - a reference to the fact that the mechanism to grant future windows is typically just a number that grows upward slowly after each acknowledgment, sliding upward.

(Wendell, 2013 Sect. Glossary)

Front 11

URL

Back 11

Uniform Resource Locator

A standard for how to refer to any piece of information retrievable via a TCP/IP network, most notably used to identify web pages. For example, http://www.certskills.com/blog is a URL that identifies the protocol (http), host name (www.certskills.com, and webpage (blog)

(Wendell, 2013 Sect. Glossary)

Front 12

VoIP

Back 12

Voice over Internet Protocol

The transport of Voice traffic inside IP packets over an IP network.

(Wendell, 2013 Sect. Glossary)

Front 13

Web Server

Back 13

Software, running on a computer, that stores web pages and sends those web pages to web clients (web browsers) that request web pages.

(Wendell, 2013 Sect. Glossary)
