Access Layer 167 - ANSWER Provides access to the network, network designs
begins with it, primary wireless LAN.
ACK - ANSWER Acknowledgement is a signal passed between communicating,

Address Resolution 130 - ANSWER to send a message, must be able to translate
application layer address of the destination to the network layer address and
translate that to the data link layer address
ARP 132 - ANSWER stands for address resolution protocol, basically translate the
subnet to another computer then it is being processed by all computers in the same
LAN..
ARQ 100 - ANSWER this stands for automatic repeat request. Once error has been
detected, it must be corrected. The simplest, most effective, least expensive, And
most commonly used method for error correction is retransmission. With
retransmission, a receiver that detects an error simply asks the sender to retransmit
the message until it is received without error. There's two types, stop and wait and
continuous.
Asynchronous Transmission - ANSWER is often referred to as start-stop
transmission because the
transmitting computer can transmit a character whenever it is convenient, and the

Baselining - ANSWER Baselining is a method for analyzing computer network
performance. The method is marked by comparing current performance to a
historical metric, or "baseline".
BGP - ANSWER is a dynamic distance vector exterior routing protocol
used on the Internet to exchange routing information between autonomous systems
—that
is, large sections of the Internet. Although BGP is the preferred routing protocol

that use a variety of different components on different parts of the network.
Circuit loading - ANSWER the amount of data transmitted on a circuit
Common Carrier - ANSWER Big phone carriers such as at&T
Core layer - ANSWER The third network architecture component is the campus
backbone (sometimes called
the core layer), which connects all the buildings on one campus. The campus
backbone is
usually faster than the backbones we use inside buildings because it typically
carriesmore
traffic than they do. We use routers or layer 3 switches that do routing when we
design the
campus backbone.
Cost Assessment - ANSWER the relative costs of the technologies are considered
DHCP - ANSWER - The most common standard for dynamic addressing is
Dynamic Host Configuration
Protocol (DHCP).
Data Center - ANSWER The fourth network architecture component is the data
center, which contains the
organization's servers (e.g., database servers, email servers).
Distribution Layer - ANSWER The second network architecture component is the
building backbone network, which some vendors call the distribution layer, because
it distributes network traffic to and from
the LANs.
DNS - ANSWER Server name resolution is the translation of application layer
addresses into network layer addresses (e.g., translating an Internet address such
as
www.yahoo.com into an IP address such as 204.71.200.74).This is done using the
Domain
Name Service (DNS)
E-commerce Edge - ANSWER The final network architecture component is the e-
