Attendance and Partcipation
The College designates this class as a Synchronous Online class, as such, we shall hold class meetings and exams online. It is required to attend the online class meetings unless prearrangement is made with and approved by the instructor, or is permitted by Federal and State laws and regulations and the policies of of the College.
Reference to the state law regarding non-attendance because of religious beliefs is in the Undergraduate or Graduate Bulletin.
Student receives credit for attendance and participation in lectures. At each online class meeting, the instructor will issue an attendance poll where students enter their full name to register their attenance. In addition, there are required in-class exercises and discussion. For the in-class exercises and discussions, see the section of Assignments and Examinations for details.
Students should join the online class meetings on time. A late attendance may be recorded as absence from the class.
Assignments and Examinations
The instructor assigns self-study assignments before each week's class meetings. These exercises are to help students learn the material discussed in the lecture during each class meeting.
Students should expect 14 Pre-lecture Assignments, generally, 1 per week.
During an online class meeting, students complete activities related to the pre-lecture assignments or the lecture individually or in a pre-arranged group.
Students should expect 14 In-Class Assignments, generally, 1 per lecture.
There will be a few quizzes. Quizzes are online on [CUNY Blackboard](https://bbhosted.cuny.edu/). All quizzes are individual assignments.
Students should expect 7 online quizzes generally, 1 every 2 weeks.
Programming and Laboratory Assignments
In general, the instructor assign programming or some hands-on assignments every 2 - 3 weeks. These are for students to experiment with network tools, protocols, and systems, and often require students to write programs.
Students should expect 4 of these assignments, generally, 1 every 3-4 weeks.
Projects and Presentations
The instructor assigns projects or research paper study and presentation assignments for selected major areas of study. These assignments are group assignments. These assignments are to provide students with sufficient practice and ample exploration to master the knowledge and skills pertinent to the area, and learn to collaborate in a team setting.
For each of these group assignemnts, the instructor will place each student randomly in a team of 3-5 students.
To grade these assignments, the instructor considers the quality of the group work and individual contributions. The students shall provide a peer evaluation. The instructor will provide an evaluation on the quality of the projects. Both of the student peer evaluations and the instructor’s evaluations will be used in the student’s final grade calculation. A student’s may receive a lower grade than the project quality grade if the student makes far few contributions than her or his team members. In an extreme case, a student who does not make any contribution to the project may receive no points on a group assignment as evidenced by the peer evaluation and the others (such as, Github commit logs).
Students should expect 3 of these group assignments, generally, 1 every 3-4 weeks.
Midterm and Final Examinations
The instructor will give two exams, a Midterm Exam and a Final Exam. Refer to the course schedule for the time, the date, and the location of the Midterm and the Final Exams.

In this semester, as the College designates this class as a Synchronous Online class, the instructor will proctor the exames online as the designated date and time by the College.
The instructor adopts the Github Classroom to manage selected assignments, in particular, group assignments. The students submit their work to Github by commiting their work using a _Git_ client and pushing their work to their Github repositories.
The Github Classroom repository invitation links for this class will be distributed in class.
Late submissions are accepted, but penalized with 10% of penalty or one letter grade lower each day late. For instance, if a team submits a project one day late, the grade of the project will be lowered from A to B, B to C, and so on. In addition, a student will receive 0 on a submission of 5 or more days late.
Students final score is calculated on the scale of 100 as follows,

Tips for Online Learning Success
The College designates this class as a Synchronous Online class in this semester. Below are some tips to help us succeed in this class.
Access to the Internet and Information Technology
It is essential that you have access to Broadband Internet, and to a computer with Web camera and microphone, minimally 8 GB RAM and 100 GB disk space and with the cability to run Oracle VM VirtualBox.
Be aware that the College and the University have made resources available to aid students. For instance, the College has established the Device Loan Program for Students and the University has a Virtual Desktop service In addition, the College maintains a Student Resources and Updates that documents services that students can leverage on for success. For instance, it describes the steps to obtain free Internet services from Charter Communications and Altice USA for students to take online classes.
You will need to devote at least 12 to 16 hours per week to the required lecture, reading, programming, experimenting, writing, and reasoning. Please devise a schedule (e.g., 2.5 to 3 hours per day, 5 days a week) and keep to it.
Online Lecture Participation
The online lectures are crucial. Although the instructor records lectures, you may not have as a good experience watching the recordings as you would in person in the online lectures. However, if you are only passively watching the lecture, you can quickly lose concentration. It is important to participate in the class actively, such as, participating in polling, answering your classmates’ questions, answering the instructor’s questions, and asking questions.
Group and Peer Learning
Peer groups can be effective and beneficial to learning. You should leverage on the groups to which the instructor assigns to, or establish a group of your own, and actively discuss the relevant class topics with the group.
Video Conferencing Tools
Video conferencing tools, such as, Blackboard Collaborate Ultra has particularly useful features, such as, sharing screens and sharing files. You should master the tools and communicate effectively with your classmates and with the instructor.
The Brooklyn College Learning Center
Don’t forget that Brooklyn College has a Learning Center that is committed to help students succeed. One essential service that the learning center provides is the tutoring service. Visit the learning center online for more information.
The Brooklyn College Student Support Services
