The objective of this course is to provide students with a solid understanding of fundamentals, as well as the state-of-the-art of telecommunications in business. Telecommunication technology will be reviewed and current practices discussed. Topics include distributed data processing, communication techniques, network design, management and security, LANs and PC networking. This course is focused on the TCP/IP architecture, but the OSI model is presented and discussed. Emphasis is also given to networking using Windows, with an introduction to networking in Linux.

When you complete this course you will have the ability to:

  1. describe the components of telecommunication systems.
  2. compare and contrast various network implementations.
  3. summarize the history and current status of the field of telecommunications.
  4. design, configure and price local area networks.
  5. configure and setup Microsoft TCP/IP in Windows.
  6. manage simple networks using Windows.

Each  class meeting will be divided in two parts:  (a) fundamentals and applications: the basic concepts and techniques of telecommunications;.  and (b) networking using Windows : designing, installing and managing networks and internets using Windows. 


Class handouts will be available on the Web at the following address of the course syllabus:

The course syllabus will be linked to the class materials. You can see and print the class materials at the Lab and from your office or home (an Internet provider costs between $10-20 per month), using a Web browser.

Note: To print properly this syllabus set top and bottom margins to 1" in your browser.


Assignments (5) 25%
Quizzes (4) 20%
Project 25%
Final exam 30%


All assignments are to be done individually and are to be submitted as a file in SAKAI or (marked web) are to be posted on the Web and the page URL submitted in SAKAI. Assignments are due as shown in the outline, unless specific due dates are indicated in the assignment's page (link).
  1. Hands-on network information. Test your download speed and how long it takes to reach a Web site.
  2. How much would cost to network 20 PCs using two switches (assume they are in acceptable distance) in terms of NICs, switches, wiring, etc (do not include software)? Do a simplified drawing representing your network. Include your answer (with specific brands of your choice) and the network image in a Web page (web).
  3. Resolving names and what's in a name? Exercises on IP and NetBIOS resolution in Windows.
  4. Obtain IP information from a PC running Windows and Linux.
  5. Assume you received a class C IP address ( and you are setting up a network with 4 subnets, each with 50 users. Please select a subnet mask, explain why you did it, and show the range of IP addresses in each subnet. Draw an image to show the network  Include your image and answers in a Web page (web).


Four on-line, multiple-choice quizzes covering topics in prior weeks, but non-cumulative.  The exam will open two days before the due date and will be comprised of twenty randomized questions. The grades will be posted immediately in SAKAI, but the comments will only be available the day after the due date.

Final exam

A comprehensive, in-class, multiple-choice, open book exam on December 9, covering class materials from September 2  to December 2.


The project is to be done in group. The objective is to design a local area network for a real or hypothetical organization comprised of at least four subnets, with at least 100 PCs in each, using Windows and TCP/IP. Both hardware and software design are to be done, assuming that the organization already has the PCs in stand-alone mode (you do not need to include their costs). It should include equipment list and prices, IP numbers assignments, domain(s), etc. Prepare a graphical representation of the network usaing MS Visio. List the materials, including brand name, quantity, prices and total cost. Explain all your design decisions. Document your project posting it on the Web and post the URL on December 10, 2012.
