Sir Garry Allison and Sir Phil Reed Present
NETWORKING
Garry has done it at home. Phil Reed has had a volunteer do it at the
San Ramon Senior Center. It's networking - the connecting of two (or more)
computers so they will work together.
Learn the why and how at this meeting.
Following are Gary's outline then Phil's notes
Home
networking and the internet
Remember
the early1950s?
One TV per household.
Most PC's now come with a NIC.
There are many ways to connect computers together.
There are many ways to connect those networked computers to the
internet.
Two steps involved.
Create the network
installing the hardware, NIC
installing necessary software,
setting up the computers so they can talk to each other.
Create a shared internet connection.
Wired or unwired
how to connect together
wired (new wires required)
need NIC in each computer (2nd NIC if cable modem)
cable (RF or twisted pair RJ45 Cat 5 connector)
Hub
wired (no new wires)
phone lines (must use same phone line)
power lines (stay upstream of surge suppressors)
wireless (many venders not compatible)
RF
Wi-Fi (IEEE 802.11b)
Bluetooth for PDA's
can mix and match but need bridges or adaptors)
Regardless of network system type---in each computer you must:
Install a NIC in each computer
Decide type
of network ie server/client or peer to peer.
Install the
software (NIC drivers) for the installed NIC to communicate between computer
system and NIC
Install
protocols so that the computers can talk to each other (language or rules)
TCP/IP (Transmission Control Protocol/Internet Protocol
NetBIOS/NetBEUI (Network Basic Input Output System/Network BIOS Enhanced User
Interface) for Windows PCs or
AppleTalk for Mac based systems.
IPX/SPX (Internetwork Packet Exchange/Sequenced Packet Exchange)
Install
network clients (so computers can find self and other computers)
Install
network services (so files and printers can be shared)
Networking between PCs and Macs
Must install
software either on the Mac or the PC (but not both) so they can communicate
with each other.
MacOS X.1or later includes support for PC file and printer sharing.
DAVE by Thursby Systems lets Macs talk to PCs
PC MacLan lets PCs talk to Macs.
Need to
install translation software so one computer can read the files from the
other.
MacLinkPlus by Dataviz for the Mac and Conversion Plus for the PC.
Office 98 installed on a Mac and Office 97 installed on a PC can do the
translation.
Notes
All computers
on your network must be on the same workgroup
Each computer must have a different name.
Not more than 15 characters
Don't name the with numbers use letters if you must.
Passwords are required on a network.
Can get used to it or
Can fix by setting primary network logon in network control panel to Windows
logon. (only other choice is Client
for Microsoft networks.)
Check connection
Double click
on network neighborhood or my network places icon on the desktop.
Should see
the computer you are sitting in front of and all of the other computers on the
network in the workgroup.
If you did you are a
network guru
If not, Windows 98 SE, Window ME and XP have networking troubleshooters. I
If that doesn't work, call Phil he is a "Network Administrator"
Networks can do neat things
Share printers.
In the printers properties on the computer the printer is attached to click
sharing tab and then highlight
as
shared button and give the printer a name.
Then you must install the printer drivers on each of the other computers on the
network. click on add printer in the printers folder and then click on button
to designate network printer then browse to that printer using network
neighborhood or my network places. The computer you are sitting in front of will
transfer the necessary drivers from the computer where the printer is attached.
Share drives
Go to My Computer, right click on the drive, click on share tab and tell the
computer the name of the drive to be shared.
Share
scanners
Play networked games
Internet connection sharing
Notes
Need IP address (ex 207.30.37.115)
can be fixed or dynamic
usually automatically assign by your ISP
might be using PPPOE (Point to Point Protocol over Ethernet)
Each computer needs IP address
Through software
If client/server network then you need proxy server software.
If peer to peer and you have Win98SE or later use Internet
Connection Sharing Not typically installed
install only on computer attached to the internet
install ICS client on other computers.
Through hardware
router or gateway
hub needed
Security concerns
Need antivirus application on each networked computer
Need a firewall application (XP has a firewall) on each computer
From Phil:
This is what the San Ramon
Senior Center has done (there are some drawn in lines
missing)
Draw a line (RJ45) from the cable modem to the left side of the router.
There are four lines coming out of the right side of the router, three go to
each of the three PCs on the right and the fourth goes into the hub. The
one going into the hub is a crossover cable. There are three lines coming
out of the hub going to the three PCs on the left. In addition there is a
line going from each PC to the printer which is above it.

Decision Trees:
There are two and they are rather long.
The first is for no network and no
notebook
The second is for Ethernet in one room and no notebook
In addition there were two reference
hand outs:
