destination IP address

Which logical address is used for delivery of data to a remote network?

data link

At which layer of the OSI model would a physical address be encapsulated?

message encoding, 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?

transport

Which layer of the OSI model defines services to segment and reassemble data for individual communications between end devices?

enable software and hardware to work from different vendors

Why are open standards important in the data communications industry?

default gateway

a router that is responsible for redirecting the packets it receives to their destination

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

encoding, formatting, encapsulation, timing

what are some of the four major responsibilities of network protocols

they are dropped

what happens to frames that are too long or too short for the channel used

Bit, frame, packet, segment, data bfPSD

what is the correct oder of data de-encapsulation

Segment

what is the transport layer PDU?

protocol suite

what name is given to a group of interrelated protocols necessary to perform a communication function

physical address, network address, process number, gateway address

what pieces of information are required for a host to access resources on a remote network (4)

physical address, network address, process number

what pieces of information are required for a host to access resources on the local network (3)

network access protocol

what type of protocol describes communication over a data link and the physical transmission of data on the network media

FTP

which application layer protocol allows users on one network to reliably transfer files to and from a host on another network

flow control

which message timing factor impacts how much information can be sent and the speed at which it can be delivered?

source, channel, receiver

which of the following elements do both human and computer communication systems have in common (3)

presentation

which osi reference model layer is responsible for common representation of the data transferred between application layer services

internet

which tcp/ip model layer is responsible for providing the best path through the network
