CF chapter 7- Final

Local Area Network (LAN)

) connects nodes that are located in a small geographical area.

is a home network the same kind as the one at the corporation where i work?

No. Most companies use client/server networks. You'll be setting up a P2P network.

Bethany is in her home, watching a video she took on vacation, while her brother is playing FIFA Soccer on his Xbox, and her dad is checking stock quotes on his iPad. What kind of network does this family have?

P2P network

What kind of wire do I use to set up an Ethernet network?

The most popular transmission media option for wired home Ethernet networks is unshielded twisted-pair (UTP) cable.

How do I share an Internet connection on an Ethernet network?

To share an Internet connection on an Ethernet network, you need a router.

The type of network that would be necessary to connect the networks of two college campuses would be:

WAN

Can I set up a wireless network at home?

You can have a wireless network only if each node connected to the network has a wireless network adapter attached to it or installed in it.

what are the risks of an unsecured wireless network

Your wireless network can be piggybacked or hacked

to solve connectivity problems

access points or wireless range extenders can amplify signals to improve connectivity in areas of poor signal strength

for a home network to run efficiently

all nodes such as NICs and routers should use the same Ethernet standard

advantages of networks include

allowing users to share an Internet connection, share printers and other peripheral devices, share files, and communicate with computers regardless of their operating system.

wi fi

allows users to connect to internet wirelessly but is not as fast as a wired connection

ethernet networks

are the most common networks used in home networking. Most use a combination of wired and wireless connections, depending on the data throughput required. Wired connections usually achieve higher throughput than wireless connections. Wired home networks use the gigabit Ethernet standard.

most home network routers should support

both wireless and wired access to the internet

What is the type of broadband Internet in which the connection is degraded by adding multiple users?

cable

home network serves

can be used instead of an NAS device if your needs require more sophisticated functionalitiy than NAS devices

distance from router, as well as walls floors and large metals objects between device and router

can interfere with wireless connectivity

client

computer on which users accomplish specific tasks. Requests services from the server computer

neighbors may unintenntionally or intentionally

connect to the internet through your wireless connection, and hackers may try to access it

satellite

connection opetion for those who do not have access to faster broadband technologies -data is transmitted between a satellite dish and a satellite that is in a geosynchronous orbit

central network (client/server)

contains two types of computers: a client computer on which users perform specific tasks and a server computer that provides resources to the clients and central control for the network. Most networks that have 10 or more nodes are client/server networks.

network attached storage (NAS)

devices let you store and share data files such as movies and music, as well as provide a central place for file backups

network adapters

devices that enable the nodes on a network to access the network and communicate with each other.

devices such as gaming consoles

each have their own setup procedures for connecting to wireless networks but usually require the same info as that needed for connecting a computer to a secured wireless network

peer to peer

each node on the network can communicate directly with every other node. This means that P2P networks do not need a seperate device to control network -more often

all devices are connected you your router

either wirelessly or with a wired connection -wired connections deliver better throughput than wireless

transmission medium

establishes a communications channel between the notes on a network

: Actual data throughput is usually higher on wireless networks than on wired networks.

false

P2P networks require specialized network operating system software.

false

Satellite Internet is the fastest broadband option.

false

wireless networks are even more susceptible to

hacking than wired networks because the signals of most wireless networks extend beyond the walls of your home

the device manager utility

in windows lists all adapters installed on your computer

mobile broadband

is a 3G or 4G service delivered by a cell phone network

Metropolitan Area Network (MAN)

is a large network in a specific geographical area.

home area network (HAN)

is a specific type of LAN located in a home.

networks

is simply two or more computers that are connected together via software and hardware so they can communicate

a computer network

is simply two or more computers that are connected using software and hardware so they can communicate. -can be defined by the distance between nodes or level of adminstration

Personal Area Network (PAN)

is used for communication among personal mobile devices using Bluetooth or Wi-Fi wireless technologies.

Which of the following should you NOT do to secure a wireless network?

keep the default network name and router password

wireless range extenders

lengthens the reach of an existing wireless signal without the need of cables, thus enabling a user to access the internet from areas that are not near the router

Before creating a home network, you should do which of the following?

list all of the devices that will connect to the network

the latest versions of windows

make it easy to set up wired and wireless networks

which of the following is used to access the internet when wifi is not available

mobile hotpost, 3g internet access, 4g lte internet access

What two devices are often combined into one device in a small network to connect the home network to the Internet and to share the connection between devices on the network?

modem and router

Some of my devices don't need wireless and would work better with a wired connection. Are there different types of wired networks I need to choose from?

most wired netowkrs for the home are ethernet networks

local (peer to peer ) network

networks enable each node connected to the network to communicate directly with every other node. Most home networks are P2P networks.

home networks need

operating system that supports peer-to-peer networking. Windows, macOS, and Linux all support P2P networking.

cable transmits data

over coaxial cable, also used for cable television

use SMB protocol to

share files in networks with both windows PCS and Macs

Which of the following would NOT be a benefit of networking computers?

sharing software licenses

Which of the following would NOT be a benefit of networking computers? sharing printers and other peripherals

sharing software licenses

Wide-Area Netowrk (WAN)

spans a large physical distance

Which of the following does NOT accurately describe fiber-optic broadband?

speed drops as the distance from the main signal source increases

disadvantages for larger networks

that they require administration and that they may require costly equipment.

you may not get the throughout you need through a wireless connection

therefore you may need to consider a wired connection for certain devices

create a windows homegroup

to share files and peripherals on a windows network

To facilitate sharing peripherals and files on a Windows network, you need to establish a HomeGroup.

true

You can attach more than four wired devices to a network by using a switch.

true

Servers on client/server networks

use network operating systems (NOS)

wireless networks

use radio waves

wired networks

use various types of cable to connect nodes, including unshielded twisted-pair cable, coaxial cable, and fiber-optic cable. The type of network and the distance between the nodes determine the type of cable used.

fiber optic cable

uses glass or plastic fiber strands to transmit data via light signals

wireless network

uses radio waves instead of wires or cables as its transmission media.

DSL

uses twister pair wire, similar to that used for telephones

to add additional ports to your network

you can connect a switch to your router

to prevent unwanted instrusions into your network

you should change the default password on your router to make it tougher for hackers to gain access, use a hard-to-guess SSID (network name), disable SSID broadcasting to make it harder for outsiders to detect your network, enable security protocols such as WPA or WEP, create a network passphrase, implement media access control, limit your signal range, and apply firmware upgrades.

How can I share an Internet connection on a wireless network?

you'll need a special router to share an internet connection on a wireless network

is there a good reason to set up a network for two computers?

By setting up a network, you can share a broadband Internet connection.

two main types of networks

Client-server and peer-to-peer.

nodes

Devices connected to a network Can be computer, peripheral, game console, digital video recorder, or communications device

routers

Devices that route packets of data between two or more networks

what special problems can occur with wireless networks

Distance from router, as well as floors, walls, and large metal objects between a device and the router can interfere with wireless connectivity

what steps can be taken to secure a wireless network

Ensure a firewall is installed and make changes to several settings with your router and on your network

what are ways to improve wireless signal

Installing an access point or wireless range extender are good options

all devices must have

- a network adapter -all devices sold today contain an integrated network interface card

network navigation devices

-routers and switches -necessary for computers to comminutcate in a network

wireless ethernet networks are identified by a protocol standard

802.11ac is the ntewest standard -WiGig is a new wireless link between devices, similar to but faster than bluetooth

benefits of networks

Allow users to share peripherals. Both computers can use the printer, even though its connected to just on computer Allows users to transfer files from one computer to another without using external storage media such as flash drives Also allow users to share broadband internet connections
