Pre-Requisite:

    CECS 5030, Introduction to the Internet.
    This course builds directly on the content of CECS 5030. Although not required, students having taken CECS 5260 Computer Graphics, and CECS 5240 Web Authoring, will find that those courses enrich the learning experience.


Course Description:

  • This course will cover the design and implementation of Internet information services including FTP, conferencing, and the World Wide Web using RedHat Linux. Students design and build various information services using software tools and hardware platforms representative of those used in education and training.

Course Requirements:

  • There will be assigned homework problems that will be completed in teams. Each team will build and administer a Linux box over the course of the semester. Projects will require the team to spend time working together on their server. At first this will require time locally at the computer, but over the course of the semester administration can take place remotely. To plan a minimum of six to nine hours a week of outside preparation is a safe time allocation for successfully completing this course.

Server Space:

  • Each team will be assigned a server. Location of equipment will be discussed in class.

Course Topics and Objectives:

    1. Discuss the allocation and structure of IP addresses and DNS names in the identification and location of internet services.
    2. Install & configure FTP daemon software to provide file transfer ability from a host system with appropriate public and private security.
    3. Install & configure software to provide both a "private" collaboration forum and with controlled access.
    4. Discuss the challenges posed in the educational environment posed by access to the Internet, with emphasis on access by minors to inappropriate content.
    5. Install and configure a World-Wide Web Server. Demonstrate the use of logging, performance tuning, and security parameters in the provision of a functional information system.
    6. Implement remote management of a Web server with appropriate security considerations.
    7. Develop textual and graphical content for the World Wide Web using HTML coding techniques including lists, tables, frames, image maps, absolute links, relative links, and mailto tags.
    8. Explain the technical differences between graphic material designed for print and graphic material designed for Web delivery. Demonstrate techniques for scaling and converting computer graphic materials for Web presentation.
    9. Explain the role of Database back-ends in the development of Web-based information services.
    10. Implement a simple (i.e. based on a standard template) database-driven web application for discussion/collaboration or data collection (i.e. survey response).
    11. Install a server-based streaming audio/video delivery system. Demonstrate the interrelated role of the Web Server and streaming media server in the delivery of prepared streaming media content.
    12. Explain the relative advantages and disadvantages of alternative methods for delivering audio and video content in a network environment.
    13. Discuss network capacity planning issues in the context of streaming media delivery systems.
    14. Discuss Educational policy implications for "acceptable use" of Internet services with minors.
    15. Discuss the role of proxy servers in accelerating access to remote Internet services in the context of slow communications links.


Grading:

    The class lectures will cover the assigned reading materials. Selected topics and assigned projects will also be discussed in class. There will be a midterm exam, final exam, and projects during the semester. Points will be awarded as described follows:

    A total of 100 points for the course will be allocated as follows: Letter grades will be the higher grade resulting from the following two standards:
    Mid-Term Exam20 points
    6 Assignments 90 points
    Final Exam 20 points
    Total130 points

    >=90
    ATop 10%A
    >=80<90BNext 20%B
    >=70<80CNext 40%C
    >=60<70DNext 20%D
    <=59FLast 10%F
     

    Late homework will lose 5 points each week it is late. Any assignments not turned in by the last class meeting will be assigned a grade of zero, unless the student has made prior arrangements with the instructor.

    Assignments that fail to function will be assigned a grade of 0. Homework that does function but that outputs incorrect answers for the given data set or does not meet the specification of the assignment will receive 50% of the assignment points.

    Students may elect to correct an assignment and resubmit for a re-grade. A student may resubmit work two times. Resubmitted homework when corrected and functional will count 80% of the original points.

    Students are encouraged to carefully check the logic and the output of their assignments before submitting them for review and grading.

Contact Information:

 

    E-mail is the best method to contact us, since we check our e-mail multiple times daily. Although we will try to answer e-mail within one day, many students in previous semesters have been able to have their questions answered with very short turn-around times at all hours of the day and night using this procedure. Electronic mail is also an extremely effective system for setting up appointments -- it is frequently possible to set up a meeting on shorter notice than the 24-hour minimum notice that is required when making appointments through the departmental office staff. Students may use our cell phone number's to contact me outside office hours. Please use appropriate discretion at what times you call.

Class Attendance
Attendance and punctuality are professional behaviors expected of educators. Educational or Instructional technology is not "doing computer projects" - it is much more. Hence, you need to be in class for discussions and learning activities.

Due dates, for all assigned materials, will be announced in advance. Changes, on the assignment's requirements or due dates may be announced at later dates, in class, therefore attendance to all classes is necessary. It is the student's responsibility to keep up with these updates and to have all assignments ready on time. If you miss a class, YOU are responsible for what occurred, please make arrangements with classmate for notes, hand outs, etc. Any student, who has to be absent on an assignment's due date, may arrange to have the assignment submitted early.

You must notify your instructor in advance if any exam is to be missed. If an exam is missed without prior notification, 20% will automatically be deducted from the exam grade. Make-up exams must be taken outside of regularly scheduled class time. Any missed exam must be made up within one week of the scheduled time. Date and time to be determined by the instructor upon student request.


Academic Ethics:
Students are expected to create and edit their own assignments and take tests without outside assistance. This is a programming class and it is acceptable to ask for help from others after you have put forth significant effort to debug written code that is not working correctly and when testing your software. However, asking for help in debugging does not mean you have someone rewrite your code. All work is expected to be your own. Cheating and disciplinary action for cheating is defined by the UNT Policy Manual Code for Student Conduct and Discipline. Cheating is an act of academic dishonesty. It is defined and is to be handled as follows:

"Plagiarism and cheating refer to the use of unauthorized books, notes, or otherwise securing help in a test; copying tests, assignments, reports, or term papers; representing the work of another as one's own; collaborating without authority, with another student during an examination or in preparing academic work; or otherwise practicing scholastic dishonesty."

Although there are other possibilities, you should expect that the penalty that will be assigned for such infractions will include a failing grade in the course and a recommendation that you be denied a degree. You are expected to conform to all policies of the University of North Texas and work within the honor code.

As defined by the United States Copyright Act, it is your responsibility to clearly identify all elements in your work that are not ≥original works of authorship.≤ You are expected to strictly obey the provisions of all laws of the United States and the State of Texas in the completion of all course activities, taking particular notice of the provisions of the United States Copyright Act (Title 17 United States Code). This law provides that you may legally use, within certain limitations, certain copyrighted materials in the context of research and scholarship. Do not confuse your ability to legally copy materials under the ≥fair use≤ provisions of the Copyright Act with the ability to claim that such a copy is an original work of authorship.

For more information on academic dishonesty, please refer to your current student catalog.

Americans with Disabilities Act Compliance:
The Department of Technology and Cognition complies with the Americans with Disabilities Act in making reasonable accommodations for qualified students with disabilities. This university will adhere to all applicable Federal, State, and local laws, regulations and guidelines with respect to providing reasonable accommodations as required to afford equal educational opportunity. It is the student's responsibility to contact the faculty member outside of class to make any arrangements involving special accommodations and/or the Department ADA Representatives: Dr. Bertina Hildreth and Dr. Cathie Norris. Their offices are in Matt 316. You may schedule an appointment by call (940) 565-2057.

EEO/ADA on Discrimination:
The University of North Texas does not discriminate on the basis of race, color, religion, sex, age, national origin, disability or disabled veteran status in its educational programs, activities, admissions, or employment policies. In addition to complying with federal and state equal opportunity laws and regulations, the university through its diversity policy declares harassment based on individual differences (including sexual orientation) inconsistent with its mission and educational goals. Direct questions or concerns to the equal opportunity office, (940) 565-2456, or the dean of students, (940) 565-2648. TDD access is available through Relay Texas: (800) 735-2989.
