Basic Networking With: Kevin Walker and Troy Cormier

Two Types of Networks Peer to Peer Client Server

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.

Types of cabling (Coax, Cat 5, Fiber) 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

Is a the slowest network Coax Network Cable Coax - 555ft length limit. Connected in series. Prone to failures Is a the slowest network

Is connected in parallel by Hubs or Switches 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.

Hubs Are 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)

Setting Up Internet on Your computer if you are on a school internet (Determining TCPIP Network type) TCPIP – Transport Connection Protocol Internet Protocol You must first find out from your network administrator if your network has static or dynamic TCPIP addresses. Each computer on your network must have a unique TCPIP address. (Like a House address) The Two Types of TCPIP Addresses are: 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.

Setting up Internet for a DHCP TCPIP Network You must have a working network card installed in your pc. You must have a link light on your network card. (signifying a good network connection) 1.

Trouble Shooting Networks (Part 1 of 2) Coax Network - Check connectors to make sure they twisted together good. Check to make there is not a break in the line Check to make sure that the terminators have not been removed. Cat 5 Network – Check for link light Check for a link light on the hub Check color code on network cable Watch for breaks in the cable Trouble shooting your Frame relay link with Rapides Parish School Board 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)

Trouble Shooting Networks (Part 2 of 2) Ping the gateway at the school board office (10.1.1.1) (at a dos prompt type in ping 10.1.1.1) If the school board gateway does not respond there is a problem with the frame relay Ping a web site out side of School board Network (www.yahoo.com) (at a dos prompt type in ping www.yahoo.com) If you do not get a response then LaNet is down
