SUMMER 2023

Course Requirements

This class will be held ONLINE-SYNC. The instructor will provide online sync lecture.

In this course CISCO CCNA v7 Intro to Computer Networks resources will be used.

Major announcements related to class will be posted on my web site. (http://www.mcs.csueastbay.edu/~lertaul/) Check regularly announcement section from class web page. (http://www.mcs.csueastbay.edu/~lertaul/)

Office hours will be held on ZOOM/SKYPE.  (Skype ID: CSUEBLERTAUL ) Students can talk with the instructor using SKYPE for their questions during office hours.

Course Description: 

Focus on the architecture, structure, functions, components, and models of the Internet and other computer networks. Principles and structure of IP addressing and the fundamentals of Ethernet concepts, media, and operations are introduced. Students will build simple LANs, perform basic configurations for routers and switches, and implement IP addressing schemes. Preparation for Cisco certification examination (CCNA v7 Introduction to Networks)

Course work and Grading: 

LABS/QUIZ/CYU/SYN/ACT completion	35%
Module Group exams	15%
Midterm (Packet Tracer Activity)	15%
Skill Based Final  (Packet Tracer Activity)	20%
Final Exam (online Multiple Choice)	15%

Final Grades are based on total course %. 

Final grades are assigned based on total points accumulated. Students earning similar point totals will receive similar letter grades based on the following approximate distribution.

Plus and minus grades will be assigned as appropriate within the given categories. The instructor reserves the right to adjust the grade distribution up or down as needed based on the distribution of points in class to ensure parity in grading.

University policy states that no final exam may be taken before or after the scheduled time for any reason.
