Connectionless correct answers No connection is needed to transfer data.
Connection oriented correct answers Before data can be transferred, the two communicating
parties must agree to communicate by establishing a connection.
Encapsulation correct answers Adding layer headers to the data to create a new packet.
Error control correct answers A function provided by a layer that will detect and try to correct
packet loss and packet corruption.
Flow control correct answers A function provided by a layer that will slow the sender's packet
transmission rate when the receiver starts to get behind.
Layered network functions correct answers A set of operations provided by a layer in
coordination with its peer layer on another device in the network designed to provide network
services. Functions enable the services provided by a layer to work and rely on the services
provided by the lower layer.
Multiplexing correct answers When a layer provides service access points to multiple upper
layers and in turn only uses service access points from one lower layer to send and receive the
packets for the multiple upper layers.
Network layer correct answers A functional component of a network architecture that has a
defined set of inputs and outputs and provides a set of functions that aid in the operation of the
network.
Packet correct answers A block of data that is passed between layers.
Packet header correct answers The part of the packet that is added by a layer to enable the
protocol to function.
,Protocol correct answers A set of rules that govern the interaction between two peer layers in the
network architecture. The protocol is used to carry out the functions of the layer.
Reassembly correct answers A function provided by a layer that combines packets that were
segmented by a peer layer back into the original data element.
Router correct answers A network device that is responsible for moving data from one network
to another network. A router understands the route the data needs to take to get from the sender
to the receiver.
Segmentation correct answers A function provided by a layer that divides the data received from
an upper layer into multiple smaller data elements.
Service access point correct answers The set of services provided by a network layer. SAPs are
often defined as a series of subroutine calls.
Protocol diagram correct answers A diagram used to show the interaction between two entities
using a protocol. The diagram shows the information flow and the timing between information
exchanges.
Frame correct answers The name used to describe the packet used by the data link layer in the
OSI networking model.
Nonlayered services correct answers Used to describe network services that need access to one
or more layers directly, without using other layers. Often used in network management.
OSI model correct answers A seven-layer model that describes the high-level functions that
should be provided by each of the layers that make up a complete network implementation.
, TCP/IP model correct answers A four-layer model that describes the high-level functions that are
implemented to support the Internet.
User space correct answers Programs that run in user space have the same access rights as the
user that is running them, which can limit the access the program has to system files.
Ethernet correct answers A standard maintained by the Institute of Electrical and Electronics
Engineers (IEEE) that describes the common local area network used by most computers today.
Open-source protocol correct answers A protocol specification that is made public and is often
reviewed and discussed by many people before adoption.
Proprietary protocol correct answers A protocol specification that is not public.
Protocol specification correct answers A document that describes the services, functions, packet
formats, and other information needed to implement a protocol layer.
Request for Comment (RFC) correct answers A protocol standard that is created by individuals
or groups associated with the Internet Engineering Task Force (IETF).
Standard correct answers A protocol specification that has gone through a process of review and
verification and then is published so multiple vendors can use it to interoperate.
Address correct answers Used to identify a computer, network device, application, protocol
layer, or any other entity within a network.
Application address correct answers The address used to identify and distinguish between
different network applications running on a computer.
