    Exercises

    Exercises will take place live via BigBlueButton on several different time slots per week. You will get the URL and access code for your exercise group after the exercise registration period.

    Please take note of the exercise schedule published in the slide set (see above). There are some weeks where there is no exercise class!

    Exercise registration and submission of solutions

    This is covered in detail on the first assignment sheet.

     

    Information about online exams

    This semester due to the coroni situation the exams will be held as a written online exam. Please carefully read the following information and instructions!

    Please pay attention:

    UPDATED Sept 17: undefinedThis document contains the front pages of the SECOND exam PDF (for Monday September 20). It can be printed and filled out in advance and we recommend to do so, especially if you don't have a printer at home.

    Exam dates

    1st Exam: Thursday, 2021-08-05, time slot 10:00 - 13:00; about results see above at "Announcements"
    2nd Exam: Monday, 2021-09-20, time slot 10:00 - 13:00

    Exam duration

    The time to work on the exam tasks will be 90 minutes. Additionally, we will grant an extra time of 30 minutes to scan and upload the solutions. This means that the total exam duration from start to solution submission deadline will be 120 minutes. The exam participants can freely manage this time and are responsible themselves to submit their solution ahead of the deadline.

    Method of examination and allowed aids

    • The written exam will be held online in the form of an "open book exam". That means that the exam participants may use all of the lecture material as well as own material and notes for solving the exam tasks.
    • However, the exam must be solved independently and without the help of other persons. Any form of direct or indirect communication with other persons during the exam is forbidden!
    • Video supervision of the exam participants during the exam is not planned.

    Exam procedure

    • The PDF document containing the exam tasks will be made available via the eCampus course at the start time of the exam. In addition, a backup copy of the file will be provided via a Sciebo share at the start time of the exam. The eCampus/Sciebo addresses will be announced well in advance of the exam.
    • If a printer is available, the exam tasks may be solved directly on the printed exam form. If no printer is available, exam participants may also use own blank sheets of paper. In this case, we recommend to use squared paper.
    • The exam will contain a declaration of independent work. This declaration must be filled out (if a printer is available) or copied in exact wording (if no printer is available) and then signed by the exam participant. Without this declaration the exam solution can not be accepted.
    • The exam solution must be hand written with a document-proof pen in blue or black color. Digital-only solutions (e.g. by tablet or digitizer) are not allowed.
    • Every page of the solution must be marked with the name and matriculation number of the exam participant so that we can associate the solutions without doubt.

    Submission of solutions

    • The exam participants have to scan their solutions using a scanner or alternatively using a smartphone or digital camera. The provided solution must be exactly one file which contains all pages of the solution. We allow either a PDF file or a ZIP archive of image files. It is the responsibility of the exam participant to make sure that all solutions are clearly visible and readable. Unreadable solutions can not be graded!
    • The solutions must be uploaded ahead of deadline via the provided eCampus course. If there is a problem with eCampus, we will provide a Sciebo share as a backup opportunity. The eCampus/Sciebo addresses will be announced well in advance of the exam. Late submissions after the deadline will not be accepted!
    • The original solution document must be kept on file. In some cases the original solution document can be requested and must then be delivered to the examiners by the exam participant.

    Grading of the exam

    The exam will be normally graded. If the exam is passed, the credit points for the course will be awarded to the exam participant. The exam is safely passed if at least 50% of the exam points are achieved.

    Questions and problems

    For any questions and problems which might arise during the exam there will be a support room using the BigBlueButton system.

     

    Prerequisites (recommended)

    We recommend existing basic knowledge on computer networks and communication systems protocols, e.g. coming from appropriate courses of your Bachelor programme.

    For the Uni Bonn German programme "Bachelor Informatik" we recommend participation in the course BA-INF 101 "Kommunikation in Verteilten Systemem (KIVS)". All lecture material (slides, assignment sheets, ...) is available in English language and maybe helpful also for Master students who have not done the BA degree in Bonn. You can access the recent course material (of winter term 2017/2018) here on the KIVS web page (no username/password required from within the University computer network).
