For $500 I would have expected these cables to be worn in. They aren’t. The procedure for pre use wear in of digital cables is significantly different to analog cables. They should be worn in for a period of 24 hours in each direction. Use a unidirectional protocol! _Never_ use TCP for wearing in digital cables, as TCP uses return packets for acknowledging, causing interference in the uplink channel being pre worn. Use UDP or ICMP (no ping) for wearing. Preferable use a payload of 64Kb with a data packet consisting of consecutive 1’s and 0’s to settle the electrons. After 24 hours, reverse the cable and repeat. Always make sure that the cable is connected to a sender and a receiver, as Layer 2 will prevent data transmission if there is no positive ARP response from the receiver.

This a course on computer networking. The course is divided into eight sections. See the schedule for details.
The co-requisite for CS 514 and MIS 514 is Theoretical Foundations of Computer Science (CS 502). A good understanding of operating systems (CS 505) is helpful, as is some programming experience (computer programming essentials (CS 501A) at least, program development (CS 501B) is better, data structures and algorithms (CS 503) is best).
Class meets in Bey Hall 226 on Mondays and Wednesdays from 4:30 to 6:20 p.m. First day of class is Wednesday, 3 September; last day of class is Wednesday, 10 December. Tuesday, 4 November, is the last day to withdraw from class with a W. There is no class on Wednesday, 26 November, the day before Thanksgiving Break. Classes will be held on Wednesday, 15 October (the day before Fall Break).

Learn about computer network design, implementation, and operation. Emphasis placed on a top-down, software-oriented view of the full ISO OSI network reference model, as well as developing areas of network application.
Diligence and perseverance in this class should move you in a direction to eventually be able toThere are seven tests, one at the end of every section except the first (Introduction); see the schedule for details. Tests are given in class, and are closed book with one page of notes allowed; calculators and computers are not necessary. The tests are cumulative, covering everything in the readings up to and including the section containing the test. The whole class period is allocated to the test; once you finish the test, you may leave. Test answers and grade statistics will be made available off the schedule. There are no mid-term or final exams.
Each test has six questions, each question is worth a maximum of eight points for a maximum total of 48 points per test. The grade range is scaled to the 48-point maximum:
42 < A 36 < A– ≤ 42 30 < B+ ≤ 36 24 < B ≤ 30 18 < B– ≤ 24 12 < C+ ≤ 18 6 < C ≤ 12 0 < C– ≤ 6 F ≤ 0
This grade range applies to both CS 414 and CS 514.
The final grade is a straight, unweighted average of the four highest test grades — the three lowest test grades are dropped. The final grade comprises four grades total; each constituent grade constitutes one-quarter (25%) of your final grade.
All grades are kept with one digit of precision to the right of the decimal point and 0.05 rounded up. No grades are adjusted to a curve; that means that 89.9 is always B+, never an A-.
Pop quizzes occur spontaneously. A pop quiz is no more than five minutes long, and is given as soon as the class period starts. A pop-quiz grade ranges from 0 to 5 (inclusive on both ends) and is unappealable; see the pop-quiz rules for full details.
There are many computer networks textbooks, all more or less the same. This course has a textbook, but it doesn’t have an assigned textbook. Instead, pick a textbook or two you’re comfortable with. As a first cut, compare the book’s table of contents with the schedule to make sure the topics mentioned in the schedule appear in the table of contents. You can glean further advice from a small annotated bibliography of computer networks books.
Please do not interpret “There’s no assigned textbook for this course” to mean “Great! I don’t need a textbook.” Absorbing everything you need to know from lectures won’t be possible, not the least because there won’t be time to cover everything in lectures. Working it out over a textbook or two will give you the time and space to learn what you need to know. In addition, the tests are written assuming knowledge found in basic computer networks textbooks.
Lecture notes and reading assignments were prepared using Computer Networking: A Top-Down Approach by James Kurose and Keith Ross. If you have no idea what to do, you should at least get a copy of this book.

My attendance policy applies only to lecture attendance; it does not apply to other kinds of attendance which may be required for the course. Repeated failures to meet the attendance expectations set for tests, meetings, projects, labs or other forms of course work will have a bad influence on your grade.
Monmouth University does have a class attendance policy, which you can find in the Academic Information chapter of the Student Handbook. To the extent that I need to keep the record straight, I will take attendance. Attendance lists, however, are entirely for the University’s benefit; I will make no use of them in grading.
First, the only complaint that matters is that something got marked wrong when it was actually right. When you come to complain, be prepared to present, in explicit detail, what it is you did and why you think it’s right.
Second, complaints about a particular test or assignment are only valid until the next test or assignment is due; after that point the book is permanently closed on all previous test or assignment grades.
