Networking Basic Diagram Copyright © Texas Education Agency, All rights reserved.

IP Address 32 Bit Dotted Decimal Number: Octet Decimal Number Range Binary Equivalent (Either 0 or 1) Copyright © Texas Education Agency, All rights reserved.

Network ID RED- Bits associated with the Network ID, must remain intact for routing through the Internet Black- Bits associated with individual hosts on the network. These bits can be used to assign host addresses on the network Class A Address Class B Address Class C Address Copyright © Texas Education Agency, All rights reserved.

Basic Networking Terms Straight-Through Cable- An Ethernet cable used in networks which connect unlike devices (ex.- PC to Switch, PC to Hub) Cross Connect Cable- An Ethernet cable used in networks which connect like devices (ex. – PC to PC, Hub to Hub) Console Cable- An Ethernet cable used in networks which connect a PC to a console port of a router or switch and allows configuration to take place. Router- A network device which routs IP packets through the Internet based on the network IP address. Switch- A network device which routs network frames to their specific MAC destination address. NIC (Network Internet Card)- An adapter card which, when inserted into a computer or laptop, allows an Internet connection to that device. Packet- A packet is a unit of information which is routed through the Internet by routers. Frame- A frame is a container of data within a packet which is reviewed and sorted to individual hosts on a network by a switch. Peer to Peer Network- The simplest form of a network where a host is acting as both client and server on the network. Client-Server Network- A network where there is a central control of all network services (server) to network hosts (clients). Copyright © Texas Education Agency, All rights reserved.

Lab Diagram Set up the following equipment for each of the groups: Straight- Thru Cable Router Switch Straight- Thru Cable (3) Straight- Thru Cables Hub (3) CPU’s- with Operating Systems, Working NIC’s Copyright © Texas Education Agency, All rights reserved.

Instructions Configure all equipment with IP addresses including: Router: Gateway Network ID/ Subnet Mask CPU’s: IP Address/Subnet Mask Default Gateway TCP/IP Protocol Suite Copyright © Texas Education Agency, All rights reserved.

Instructions- Cont. Connect all cables Check system by use of “ping” to: All other CPU’s Default Gateway After ensuring correct functions, create errors in the network by doing any or all of the following: Change IP addresses of a CPU or Default Gateway to be non compatible with rest of network Use incorrect or damaged cable for any of the connections Change Subnet Mask or Network ID in router Copyright © Texas Education Agency, All rights reserved.

Instructions- Cont. Allow students to investigate the LAN in order to find out possible errors in the network Students should then repair the problem Students should then document the entire process on a Lab Report Form Copyright © Texas Education Agency, All rights reserved.
