Building Block Design Process - ✔️✔️many other organizations now use a simpler
approach to network design that we call the building-block process. The key concept in
the building-block process is that networks that use a few standard components
throughout the network are cheaper in the long run than networks
that use a variety of different components on different parts of the network.
Asynchronous Transmission - ✔️✔️is often referred to as start-stop transmission
because the
transmitting computer can transmit a character whenever it is convenient, and the
receiving
computer will accept that character.
Access Layer 167 - ✔️✔️Provides access to the network, network designs begins with
it, primary wireless LAN.
ACK - ✔️✔️Acknowledgement is a signal passed between communicating, processes,
computers, or devices to signify acknowledgment .
Address Resolution 130 - ✔️✔️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 - ✔️✔️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 - ✔️✔️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.
Baselining - ✔️✔️Baselining is a method for analyzing computer network performance.
The method is marked by comparing current performance to a historical metric, or
"baseline".
BGP - ✔️✔️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
between
, Internet sections, it is seldomused inside companies because it is large, complex, and
often
hard to administer.
BN - ✔️✔️A backbone network (BN) is a large central network that connects almost
everything on a single company site
Bottle neck - ✔️✔️a circuit that is filled almost to its capacity and thus is the critical
point that determines whether users get good or bad response times.
Circuit loading - ✔️✔️the amount of data transmitted on a circuit
Common Carrier - ✔️✔️Big phone carriers such as at&T
Core layer - ✔️✔️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 - ✔️✔️the relative costs of the technologies are considered
DHCP - ✔️✔️- The most common standard for dynamic addressing is Dynamic Host
Configuration
Protocol (DHCP).
Data Center - ✔️✔️The fourth network architecture component is the data center,
which contains the
organization's servers (e.g., database servers, email servers).
Distribution Layer - ✔️✔️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 - ✔️✔️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)
