Peer to Peer
Client Server
Two Types of Networks
Peer to Peer Networks
In peer to peer networks, there are no dedicated servers.
Each computer in this type of network can act as both as a client and a server.
There is no central security. (users may set passwords to protect shared resources)
Peer to peer networks are called workgroups.
Peer to peer networks are for small groups of people.
Windows 3.11 for Workgroups, Windows 95/98, Windows NT Workstation can be
used in peer to peer networks.
Client Server Networks
Servers are computers that share files, printers, or other resources.
Clients are computers that use the server’s shared resources.
In a client server network the servers are not used as workstations and are dedicated to sharing it’s resources.
The computers that are used as servers in this type of network are optimized to quickly service share requests and ensure the security of the shared resources.
There is central security. (uniform administration from a central location)
Windows 3.11 for Workgroups, Windows 95/98, Windows NT Workstation, Windows NT Server, and Novell can be used in Client Server Networks.
Network Connections
Network Cards
Types of cabling (Coax, Cat 5, Fiber)
Hubs / Switches
Network Interface Card
Commonly called Nic
Are built into most Brand Name PC’s
Can be different speeds 10 / 100
Have link lights to tell you if they are connected to the network
Can have connect to different types of network cables.
(Coax, Cat5, Fiber)
Network Cable Types
Coax
Cat 5
Fiber
Coax Network Cable
Coax - 555ft length limit.
Connected in series.
Prone to failures
Is a the slowest network
Cat 5 cable
Cat 5 - 320ft length limit.
Is connected in parallel by Hubs or Switches
Speed can be 10 or 100 mb
Very relilable
Fiber Network Cable
Fiber - For extremely long network runs the other cables can not make (to connect 2 buildings)
Fastest network cable.
HubsAre used to connect computers on a network that are using
Cat 5 network cable.
(Are a junction box)
Can be daisy chained to add more access points to the network. (generally you do not want to go more than 3 hubs
deep)
Can join coax, cat5 and fiber networks
(depending on hub features)
Can be 100 mb or 10 mb
(talk about the way data is sent over network)
Switches
Can be used to connect multiple hubs to a network.
Cause less traffic on the network.
(talk about the way Switches send data over network)

Static Tcpip addresses are permanently assigned. You will need to ask your network admin for an open
address.
Dynamic: addresses are assigned temporarily by a DHCP Server.

Watch for breaks in the cable
Make sure the hubs are powered up
Ping the gateway at your school (10.school number.1.1)
(at a dos prompt type in ping 10.school number.1.1)
If the gateway doesn’t respond then there is a problem at your location
Power off and on the hubs, and CSUDSU (where the frame comes in the building)
