NETWORKS (LANS AND WANS)
 Networks (LANs and WANs)
 LANs (local area network) – connected
computers.
 Network has servers and clients.
 Server.
 Provides shared resources to
network users.
 Resources such as printer/hard
drive/file, etc.
 Client computer.
 Accesses the shared network
resources provided by server.
 Resources – shared elements.

 Advantages of setting up network.
- Share hardware – printer, CD-ROM/Zip
drives.
- All can access files instead of copying
them.
- Update information.
- Set-up local e-mail – send messages to user
on network.
- Notebooks – attached/detach – update info
as needed.
- Can access needed resources when away
from office

Peer-to-peer network (workgroup).
 Fewer than 10 users.
 Has no dedicated server.
 No hierarchy among the computers.
 Each computer can function as client or
server.
Advantages to setting up network- see right
column.
WAN (wide area network).
 Computers use long-range
telecommunication links
(modems/satellites) to connect
networked computers.
 Internet is a WAN.
All networks need:
 NIC (network interface card) installed
into each computer so that a LAN cable
connecting all computers can be
installed.
 Common network card – Ethernet.
 Older Pc – had ISA
 New PC have personal component
interconnect – may not have ISDA
 Notebook have PCMCIA
 Card must fit bus architecture.
 Card must support type of cable
used to connect computers.
Can choose wireless network.
 No wires dedicated to carrying network
signals

Chapter 12
Connectivity
Consider appropriate network design
(topology).
Two common topologies for peer-to-peer
network.
 Bus.
 Uses single coaxial cable.
 Called Thin Ethernet, 10BASE-2,
thinnet.
 Need T-connectors/terminator plugs.

All computers connect to a single
cable.


Advantages to bus topology.
 Easy to install.
 Relatively inexpensive.
 Easy to expand bus network.
 Disadvantage to bus topology.
 If 3 + computers on - but one
segment of cable fails – entire
network fails.
 Becoming less common.
Star topology.
 Common for workgroup
 Uses a hub
 One end connected to hub other
to a computer (Like spoke of bike
wheel).
 Two major Ethernet speeds
 Original – 10 Mbps
 Fast – 100Mbps – most popular
 Advantage.
 Single point of failure.
 One defective cable affects
only computer it connects to
(unless hub affected).
 Each computer works - no
network connection.
 Disadvantages.


More expensive than bus –
purchase additional hardware
(hub).
Expansion of network – may need
additional hub if all connections



Wiring can become unwieldy –
especially if you cannot run
cable through walls.
 Can go wireless
 Wireless Ethernet standard –
802.11b
Either topology can use networkable printer
or any resource by connecting it directly to
a cable or to a hub.
 Only computer using printer must be on
 Printer needs network interface card
installed
Most users prefer a hub.
 Get many ports – more than # or
computers/devices
Instead of hub – install switch
 Distributes info faster than hub
May prefer router – combines hub and
small computer providing Internet sharing
Firewall – if using portable hard disks and
video camera
Server-based networks also need NOS
(network operating system).
 Tells computers how to communicate
with one another.
For networking need hardware, software,
and network administrator (system
administrator).
 Decides how hardware and software
will be used.
 Decides who will have access to
what devices and resources on
network.
 Manages day-to-day operation of
hardware, network operating system,
and resources of
the network.
Will use a peer-to-peer LAN with built-in
networking software that comes with
Windows.

LOOKING AT YOUR NETWORK
 Looking at Your Network.
 When W2KP installed – detects network
card and installs default components.
 Need to:
 Name computer (unique name).
 Setup program gives cryptic name
for computer.
 May override and name computer
yourself.
 Enter administrator password.
 Secure administrator password,
write it down, and store it in safe
place.
 Allows you to administer your
computer.
 Each user needs log on name and
password.
 My Network Places – map to network.
 Activities that follow based on specific
computer configuration.
 Guide to accomplishing tasks on your
system.
 Need to interpret screen.
 Read through if you do not have
equivalent computer setup.
 See how to manipulate a peerto-peer network.
 Most labs are on a server-based on
peer-to-peer based network.
 May not have hardware, software,
or support staff to allow activities
to be done in lab.
 What you can/cannot do depends on
lab or work environment.

SHARING PRINTERS ON A NETWORK
 Sharing Printers on a Network
 Two parts to sharing.
 Server.
 Computer with resources you wish
to share.
 Client.
 Computer that wishes to access
resources.
 In small network the print server is not
dedicated only to printing.
 If you have more than one printer, each can
be shared.
 To use printer, computer attached to
printer must be turned on.
 Can choose to use printer locally - do not
use the network

An Overview of TCP/IP
 TCP/IP - Transmission Control
Protocol/Internet Protocol.
 Data transferred over Internet through
TCP/IP.
 On Internet data travels through several
networks before it gets to destination.
 Each network has a router.
 Device that connects networks.
 Data sent across Internet in packets.
 Router transfers packet (unit of
information) to other network when
packet addressed to station outside
its own network.
 Determines best route for data.
 Rules for creating, addressing, and sending
packets are specified by TCP/IP protocols.
 TCP.
 Divides data into packets.
 Numbers each packet so they can be
reassembled at receiving end.
 IP.
 Specifies addresses of sending and
receiving computers.
 Sends packets on their way.
 IP address tells routers where to
route data.
 Data divided into packets so that:
 No large file takes up all network time.
 Data arrives correctly.
 Each packet verified as having been
received correctly.
 If packet corrupt – only corrupted
packet has to be resent.

Format called dotted decimal notation
(“dotted quad”).
Originally IP address space divided into
three different address classes (A, B, and C)
 Format of Class A, B, and C - IP
addresses differ in the number of octets
used to denote the network address and
the range of numbers used in the octets.
 Class A.
 Addresses use only first octet to
denote the network.
 Range from 0 to 127.
 Class B.
 Addresses use first two octets to
identify the network.
 First octet range from 128 to 191.
 Second from 0 to 255.
 Class C.
 Uses first three octets to identify
network address.
 First octet 192-254.
 Address 0.0.0.0 unassigned therefore
127.0.0.1 is loopback address.
Class D supports multicasting.
Class E reserved for experimental use.
To not run out of IP addresses large
organizations do not assign a permanent
(static) IP address to a computer but assign
an IP address to be used for current work
session (dynamic IP address).
People remember names better than
numbers.
Computers in organizations named to
distinguish one computer from another.
 These are in-house business names,
not IP addresses for Internet.
Because people remember names better
than numbers Internet divided into domains.
 Domain is general category that
computer on Internet belongs to.
 Domain name – easy to understand
name given to Internet host as opposed

FQDN (Fully qualified domain names).
 Host name plus domain name.
 Ex. Host name – mail and domain name
fbeedle.com then FQDN would be
mail.fbeedle.com
Fully qualified domain name must be
resolved into numeric IP address in order to
communicate across Internet.
Domain Name System (DNS) provides
name resolution.
 Divided Internet into series of network
called domains.
 Each site attached to Internet belongs to
domain.
 Large domains divided into smaller
domains – each domain responsible for
maintaining unique address in next
lower level domain or sub domain.
 Maintains distributed database, which it
uses when new domain name is
assigned.
When using browser to access a site on

 Makes your terminal into a “dumb
terminal” – each time you press key
your computer does nothing except
transmit keystrokes to remote
computer.
 Software runs at remote computer
not yours.
 Your monitor becomes monitor for
remote computer.
 Used for real time exchange of text.
 Technically Telnet is protocol and terminal
handler portion of TCP/IP protocol suite.

 Telnet is like you are sitting at and keying in
information at remote computer, remote
computer is doing all of the work and results
are displayed on monitor you are looking at.
 Example:
1. You key in 3 + 4.
2. Your computer can do nothing except
transmits your keystrokes to remote
computer.
3. Remote computer receives your keystrokes
and uses its software to do the work.
4. Your monitor then becomes the monitor
for remote computer and results of work are
displayed at terminal you are sitting at.
 Two computers agree on parameters
governing session.

UNDERSTANDING DIRECT CABLE CONNECTIONS

Understanding Direct Cable Connections
 Network solution is overkill if all you do is transfer files from notebook to desktop computer.
 Use a cable to connect two computers (use serial or parallel ports) and copy files quickly/easily
from one computer to another.
 If computers have infrared ports – do not need cable.
 W2K Professional supports standard serial null modem (RS-232) cables and following parallel
cables:
 Standard/basic 4-bit parallel cables (includes Laplink and Interlink cables).
 Extended Capabilities Port (ECP) cables.
 Universal Fast Parallel cable.

ABOUT DSL

About DSL
 Refers to both categories of DSL – ADSL and SDSL.
 Both operate over existing telephone lines.
 Both need to be relatively close to central telephone office (within 20,000 feet).
 Both require special modems.
 ADSL (Asymmetrical Digital Subscriber Line).
 Technology allows more data to be sent on existing phone lines.
 Extremely popular.
 SDSL (Symmetrical Digital Subscriber Line).
 Used primarily in Europe.
 Uses high frequency digital pulsing not used by human voice.
 Operates simultaneously with voice on same line.
 DSL.
 Data not required to change to analog and then back to digital at receiving computer.
 Transmitted directly as sent from one computer to another.
 Speed is 50 times greater over 56K modem.

DSL = Digital Subscriber Line.
Phone - voice sent on analog signal.
Computers – sent digital not analog.
Old modems – digital signals changed into analog signals to transmit and at other end back to
digital for receiving computer.
