6. Understand collision domains, broadcast domains, and frequency domains. Which network devices control which domains?
7. Understand basic network services: DHCP, ARP, DNS, NetBIOS, WINS, FTP, HTTP, POP3, SMTP, SNMP
8. Understand protocol port numbers and process sockets. Why are they used?
9. Design with and be able to implement IP subnetting for Class A, B, C networks. Understand how to find subnet addresses, host addresses, and broadcast IP addresses. Subnet masking. Complete understanding is required- must be able to design subnets.
10. Understand the use of private IP addressing (Class A, B, C)
11. Complete a comprehensive LAN case-study design project (4 subnets) that satisfies specific criteria. Network diagram, cut sheets, logical addressing table.
12. Understand data fields used in Frames, Packets, and Segments.
13. Understand WAN technology data rates and media used (analog 56K dialup, ISDN, IDSL, ADSL, VDSL, T1, T3, OC1, OC3)
14. Understand a DCE vs a DTE
15. Understand Remote Access Technologies (RAS, RC, VPN)
16. Be able to fabricate and test CAT5 UTP TIA/EIA 568 compliant cabling- straight, cross-over, roll-over
17. Understand the TIA/EIA 56X series of network standards as regards running of CAT5 from workstation to HCC, HCC to VCC, and backbone VCC CAT5 UTP and Fiber cables (MM Fiber, SM Fiber)
18. Be able to use the punch-down tool to terminate CAT5 UTP at the patch-panel
19. Install and configure the NIC in a WIN workstation
20. Completely setup a Peer-to-Peer LAN using hubs and switches
21. Configure network for file sharing, drive maps, print sharing
22. Be able to administer a small LAN
23. Understand LAN safety concerns including: proper grounding of equipment/racks, common-mode voltage hazards, static electric hazards, EMI, control of interference using Fiber.
24. Troubleshooting of LAN: ping, tracert, winipcfg, print route, and netstat utilities.
25. How to ping your own workstation to trouble your NIC
26. Network troubleshooting procedures and methodologies
27. Understand network security issues including virus prevention, passwords, access controls, resource sharing, encryption, backups, RAID

ENT 189 Course Structure & Administration
Computer Usage: Twelve PCs are utilized throughout the course to create a working experimental LAN. The PCs are networked by the students using hubs and a switch. The entire course is a study of computers and network hardware. The students are using the computers as network devices (i.e. NICs are installed in each PC to provide network connectivity). The WIN98 OS is studied and utilized extensively.
Laboratory Projects: Eight to ten required lab experiments that cover:
The following major instrumentation is used:
Oral and written communication requirements:
· Students must complete weekly lab experiments that require analysis, explanation of network device theory and composing major conclusions
· Students must complete a comprehensive network design project. This project is a “stand-alone” document with complete documentation (network diagrams, IP addressing scheme, cut-sheets, and text)
· Students must complete weekly homework that amplifies theory/practice and requires explanation
Weekly quizzes and major exams that require analysis, troubleshooting, and explanation
· Students are required to take notes of classroom discussion
· Students present their design project to the class
· Team projects where the class is broken into four Engineering Teams each with a network problem to solve. The team meets and decides upon their solution. The Instructor then chooses a “representative” from each team to write the solution on the blackboard and another team member to explain the solution to the rest of the class and answer questions
· Students complete additional “blackboard” work weekly and are required to present their work orally and answer other student’s questions about their work.
· Student attendance and class participation is required
· During Lab experiments students must be able to explain what they are doing and why they are doing it a particular way. When students need to troubleshoot problems, they must be able to articulate and document the specific problems that they are having and describe/explain any discrepancies. Students should be prepared to verbally explain experimental setups and results
· ENT 189 Students qualifying for membership in the PGCC Kappa Gamma chapter of the Tau Alpha Pi National Honor Society for Engineering Technologists (TAP) make presentations at various TAP sponsored events on campus
Evaluation of Student Performance:
Exams …………………….……….450 pts (3 exams)
Pop Quizzes ……………………….100 pts
Design project ………………….… 100 pts
Lab practicals ……………………. 250 pts
Attendance/class participation ….…..50 pts
Homework/reading assignments …... 50 pts
TOTAL .1000 points
1. Work is due at the time of the next class meeting. It is expected that the student do the assigned reading/homework PRIOR to attending class (not afterwards).
2. Use pencil only. PRINT CLEARLY. If I can’t read it- it’s wrong!
3. No photocopies accepted of any type- only originals.
4. Projects/homework/labs are to be done individually- no two should be the same.
5. Exams will be given during assigned class time (closed book). Must call in advance of exam if delayed or
can’t attend (make arrangements with the Instructor). Otherwise 10% late penalty per class.
6. Homework assignments are given during class. You must attend class to get the assignment. If you miss class you must get the assignments from a fellow student. If you cannot complete a particular Lab assignment during the time provided, inform your Instructor. Your Instructor will then make arrangements for you to complete your Lab practical during the week without penalty.
7. Pop quizzes are given during class and cannot be made up for any reason.
Student should have certain hand tools available: needle nose pliers, cutters, straight and hex screwdrivers. College will provide cable, connectors, PC workstations, required OS, cable testers, network hardware devices (hubs, switches, etc).
