Upon successful completion of this subject students should be able to:

• Describe basic TCP/IP Networks using the layered network model
• Discuss IPv6 and the future of IP
• Configure a TCP/IP network
• Understand the difference between hubs, routers and switches
• Install and Configure SAMBA
• Setup a Nameserver using BIND
• Use basic Linux networking commands
• Understand routing and routing protocols
• Understand the 802 protocols and their relationship to networking
• Configure an NFS server
