Chapter 5 Visible Networks Mike Meyers Fourth Edition

Front 1

stores the files that make up a website

Back 1

web server

Front 2

expansion card or motherboard interface that enables a PC to connect to a network via a network cable.

Back 2

NIC card

Hint 2

most modern motherboards come with it now.

Front 3

every NIC has a built-in identifier, an address unique to every single network card called what?

Back 3

media access control(MAC) address

Front 4

data is moved from one pc to another in discrete chunks called

Back 4

frames

Front 5

the MAC address how many bits long?

Back 5

48 bits

Hint 5

the MAC address is a binary number. one hex character = 4 binary characters, so there are 12 hexadecimal characters.

Front 6

an accurate mathematical method used to check for errors in long streams of transmitted data

Back 6

cyclic redundancy check (CRC)

Front 7

name coined by xerox for the first standard of network cabling and protocols

Back 7

ethernet

Hint 7

based on the bus topology

Front 8

most modern ethernet networks employ one of three speeds

Back 8

10BaseT, 100BaseT, 1000BaseT

Hint 8

use a star bus topology and connect to some type of cable called unshielded twisted pair.

Front 9

twisted pair of wires surrounded by shielding to protect from EMI

Back 9

Shielded twisted pair(STP)

Hint 9

its pretty rare to use, only used with places with excessive electronic noise

Front 10

the capacity of a network to transmit a given amount of data during a given period

Back 10

bandwidth

Hint 10

ex 100 Mbps

Front 11

Name all the CAT levels and its network bandwidth

Back 11

CAT 1 phone
CAT 3 10 Mbps, 100 Mbps
CAT 5 100 Mbps
CAT 5e 1000 Mbps
CAT 6 1000 Mbps at 100meters; 10Gbps at 55 meter
CAT 6a 10 Gbps at 100 meter segments

Hint 11

TIA/EIA establishes the UTP categories. most use 5e or 6

Front 12

what two types of connectors are used for networking?

Back 12

rj 11 and rj 45

Front 13

The TIA/EIA has two standards for rj 45 connector to the UTP cable:

Back 13

T568A
T568B

Front 14

any device that has a network connection

Back 14

node

Front 15

the default protocol for early versions of windows

Back 15

NetBIO/NetBEUI

Hint 15

one handled naming and the other chopped up data for delivery via frames

Front 16

a network transmission addressed for every node on the network

Back 16

broadcast

Front 17

is a group of computers that are located physically close to each other

Back 17

LAN

Hint 17

it is almost always a broadcast domain

Front 18

is widespread group of computers connected using long-distance technologies

Back 18

WAN

Front 19

You can connect LANs into a WAN with what?

Back 19

router

Front 20

enables dissimilar computers to share information over a network

Back 20

TCP/IP

Hint 20

the internet and windows uses this protocol. One part of it handles getting data between computers. the other handles the addressing scheme

Front 21

is the unique identification number for your system on the network

Back 21

IP address

Hint 21

part of the address identifies the network and part identifies the local computer (host) address on the network

Front 22

what does an IP address consist of?

Back 22

four sets of eight binary numbers(octets) from 0-255
for ex: 202.34. 16.11

Front 23

if the network is small, then all computers will share the first three what?

Back 23

octets

Hint 23

also called a network ID

Front 24

this tells the computer which part of its address is the network ID

Back 24

subnet mask

Hint 24

255.255.255.0

Front 25

a router has at least two IP addresses. what are they?

Back 25

one connects to your LAN
one connects to another network like your internet service provider

Front 26

The IP address of the LAN is used to send data to anything outside your network ID. This is called?

Back 26

default gateway

Front 27

these servers keep databases of IP addresses and their corresponding name.

Back 27

domain name service (DNS)

Front 28

name a few top-level domains

Back 28

.com
.edu
.org
.int
.mil

Front 29

to see your workgroup name where do u need to go?

Back 29

start
control panel
system applet

Back 30

right click on the folder
select share with

Front 31

is a group of computers and users that share a common account database and security policy.

Back 31

domain

Hint 31
