Questions and Answers Rated A+ Guaranteed Success
Application Layer(7th layer) - ans Interacts with application programs that
incorporate a communication component such as your internet browser and
email (provides user interface)
Bus Topology - ans The computers share the media (coaxial cable) for
data transmission
CAT6 (category 6) - ans Twisted-pair cables capable of carrying up to
1000Mbps (1 gigabit) of data up to a length of 100 meters
Crossover - ans Transmit and receive signal pairs are crossed to properly
align the transmit signal on one device with the receive signal on the other
device
,CSMA/CD - ans Carrier sense multiple access with collision detection is
the Ethernet LAN media-access method (used to prevent collisions in wired
Ethernet networks) Used in wireless networks for to reduce collisions.
Data Link Layer (2nd layer) - ans Layer of the OSI reference model that
handles error recovery.flow control (synchronization), and sequencing
controls which terminals are sending and receiving. Media access is
controlled (MAC) by the Data Link Layer
Deterministic - ans Access to the network is provided at fixed time
intervals
Ethernet, Physical, Hardware, or Adapter Address - ans Other names for
MAC address
Firewall Protection - ans Used to prevent unauthorized access to your
network
,Host Address/Number - ans The portion of the IP address that defines
the location of the networking device connected to the network also called
the hose address
Hotspots - ans A limited geographic area that provides wireless access for
the public
Hub - ans Broadcasts the data it receives to all devices connected to its
ports... it is possible for network devices to pick up a data intended for a
different device... considered a multiport repeater. Is on the Physical Layer
(layer 1)
IANA - ans The Internet Assigned Numbers Authority is the agency that
assigns IP addresses to computer networks
ICMP - ans Internet Control Message Protocol (preform diagnostics,
report errors, control the flow of data in the network)
IEEE - ans Institute of Electrical and Electronics Engineers, on of the major
standard-setting bodies for technological development
, Intranet - ans An internal network the provides file and resource sharing
but it's not accessed from the internet
IP Address - ans Unique 32-bit address the identifies on which network
the computer is located as well as differentiate the computer from all other
devices on the same network; they are logical addresses and can be found
using the ipconfig/all command
IP Internetwork - ans A network that uses IP addressing for identifying
devices connected to the network
ipconfig/all - ans Enables the MAC address information to be displayed
from the command prompt
ISP - ans Internet service provider
Link Integrity Test - ans Protocol used to verify that a communication link
between two Ethernet devices has been established.
