application, transport, internet, network access
The TCP/IP model consists of four layers:
protocols
The purpose of ____________ in data communications is providing the rules required for a specific type of communication to occur.
protocol model
This type of model closely matches the structure of a particular protocol suite. The TCP/IP model is a protocol model because it describes the functions that occur at each layer of protocols within the TCP/IP suite. TCP/IP is also used as a reference model.
reference model
This type of model provides consistency within all types of network protocols and services by describing what has to be done at a particular layer, but not prescribing how it should be accomplished. The OSI model is a widely known internetwork reference model, but is also a protocol model for the OSI protocol suite.
user datagram protocol
UDP stands for...
protocol data unit
What is the general term that is used to describe a piece of data at any layer of a networking model?
internet
What layer of the TCP/IP protocol model determines the best path through the network?
encoding
process of modifying data to an acceptable format for transmission
message encoding, message size, delivery options
What three requirements are defined by the protocols used in network communcations to allow message transmission across a network? (Choose three.)
local delivery
What type of delivery uses data link layer addresses?
multicast
What type of message is sent to a specific group of hosts?
transport
Which layer of the OSI model defines services to segment and reassemble data for individual communications between end devices? Port addresses are also encapsulated in this layer.
logical addresses
________ __________, also known as IP addresses, are encapsulated at the network layer.
duplex communications
_________ ______________ refers to the ability of the medium to carry messages in both directions.
default gateway
a router that is responsible for redirecting the packets it receives to their destination
TFTP
a simple, connectionless file transfer protocol. a best -efford, unacknowledged file delivery protocol. utilizes less overhead than FTP.
NAT
addresses from a private network into globally unique public IP addresses
ethernet
is a network access protocol that describes two primary functions: communication over a data link and the physical transmission of data on the network media.
HTTP
is an application protocol that governs the way a web server and a web client interact. It also defines the content and formatting of the requests and responses that are exchanged between the client and server.
IP
is responsible for taking the formatted segments from TCP, encapsulating them into packets, assigning them the appropriate addresses, and delivering them to the destination host.
TCP
is the transport protocol that manages the individual conversations. It divides the HTTP messages into smaller pieces, called segments. Also responsible for controlling the size and rate at which messages are exchanges between the server and the client.
OSPF
link-state routing protocol, heirarchical design based on areas, open standard interior routing protocol
encapsulation
process of inserting a formatted message inside another formatted message
open standard
refers to protocols that are available to the public at no cost
proprietary
refers to protocols that are developed by companies and are available to the public for purchase
FTP
sets rules that enable a user on one host to access and transfer files to and from another host over a network. Also a reliable, connection-oriented, and acknowledged file delivery protocol
PDU
the form of a piece of data that is associated with each protocol layer
application
this layer contrains protocols used for process-to-process communications
transport
this layer defines services to segment, transfer, and reassemble the data for communications between the end devices
