Networking Technologies Presentation

Presented by David Fisher

June 4, 1999

West Lafayette, IN


What is a network l.jpg
What is a network?

  • A group of computers and other devices that communicate together and share resources (i.e. file storage space and printing services).


What devices can i find on a network l.jpg
What devices can I find on a network?

  • Printers

  • Modems

  • Fax machines

  • Cameras

  • Robots

  • Computers


Terms l.jpg
Terms

  • Mbps - MegaBits per second

  • Nic - Network interface card

  • IP - Internet Protocol

  • TCP/IP - Transmission Control Protocol Internet Protocol

  • Protocol - set of rules for communication for network devices.


What kind of networks exist l.jpg
What kind of Networks exist?

  • WAN - Wide Area Network. Exists between buildings, states, countries.

  • LAN - Local Area Network. Normally thought of as within a building.

  • MAN - Metropolitan Area Networks


Are all networks the same l.jpg
Are all networks the same?

  • Ethernet - Most popular. 10 Mbps.

  • Fast Ethernet - 100 Mbps

  • AppleTalk - 2 Mbps. Not routed at Purdue.

  • Token Ring - 4 - 16 Mbps. Passes a token.

  • ARCnet - 2.5 Mbps (20 - 100 for ARCnet Plus). It too passes token.

  • FDDI - Fiber Distributed Data Interface - Backbone Stuff


Are there other differences l.jpg
Are there other differences?

  • Server-based networks - client/server

    • Monolithic vs. Distributed

      • Provides centralized administration

      • Push/Pull installations

      • Software metering

      • Standardized security


Slide8 l.jpg

  • Peer-Peer Networks

    • Loosely organized group of computers (workgroups).

      • No centralized administration

      • No big server costs


Are there still other differences l.jpg
Are there still other differences?

  • Topologies - Star, Bus, Ring

  • Wires/Lack of Wires

  • Protocols (IP, IPX, NetBEUI)


Topologies star l.jpg

Thanks to:

http://www.dcs.uky.edu/~griff/

Topologies - Star

Advantages

Less expensive

More reliable

Disadvantages

Takes more cable


Topologies ring l.jpg

Thanks to:

James Griffoen

http://www.dcs.uky.edu/~griff/ :

Topologies - Ring

Advantages

Equal access - token passing

Disadvantages

One break takes everyone down


Topologies bus l.jpg

David Fisher:

Thanks to:

Topologies - Bus

Advantage Relatively inexpensive

Disadvantage One break takes everyone down


Media types l.jpg
Media Types

  • UTP - Unshielded twisted pair

  • STP - Shielded twisted pair

  • Coaxial (thick and thin)

  • Fiber Optic

  • Infrared

  • Radio

  • Microwave


Common protocols l.jpg
Common Protocols

  • TCP/IP - Unique IP needed

  • SLIP/PPP - dial up access

  • IPX/SPX - Novell

  • NetBEUI - Microsoft

  • AppleTalk

  • DLC (Data Link Control) - HP Jetdirect


Connectivity devices l.jpg
Connectivity Devices

  • Repeater - connect network segments

  • Hub - connects nodes (star)

  • Switch - smart hub

  • Bridge - filters/moves data between segments (MAC address)

  • Router - filters/moves data between segments (logical address)


Is there a better way to look at this l.jpg
Is there a better way to look at this?

  • Yes ….

    It’s called the Open Systems Interconnect (OSI) Model.


Osi model l.jpg

Thanks to:

www.osilab.ch

OSI Model


Osi model further l.jpg
OSI Model (further)

  • Physical - cables or other media

  • Data Link - data broken into frames, linked to MAC address

  • Network - Adds extra headers to frame, translates between MAC and network address

  • Transport - Assembles packets, checks for errors


Slide19 l.jpg


Network device l.jpg

Application - Boogie

Presentation unknown

Session - unknown

Transport - proprietary

Network - proprietary

DataLink - unknown

Physical - IR

Network Device?


Evaluating the furbish network l.jpg

Advantages

Runs on AA batteries

IR connection

Limited self-correcting behavior

Disadvantages

Limited battery life

Proprietary interface

Irritating interface

Can’t feed after midnight

Evaluating the Furbish Network


Interactive session 1 l.jpg
Interactive Session 1

  • Look at the configuration of your own machine.

    • What protocols are you running?

    • What clients are you running?

    • What kind of network interface card do you have?

    • What’s your IP address?


Interactive session 2 l.jpg
Interactive Session 2

  • Exactly how hard is it to install nics?

  • Wanna try to install memory also … it’s not exactly networking, but two hours is a lot to fill and the case is already open …...


How does networking lend itself to restaurants hotels etc l.jpg
How does networking lend itself to Restaurants, Hotels, etc?

  • Shared Databases

    • Database can be shared and updated with a number of people. OS or NOS provide security and reliability.

    • Web interfaces will revolutionize e-commerce. (BIG plug … data-mining is the future).
