CS601 Notes Lectures 1-88 by DeTechnocrats

Better-to-Know

Assalam-o-alikum! This is Dr. Eerie, a student at VU, holds many certifications in the domain of cybersecurity & networking, intermediate in Python3, founder of “De Technocrats” etc. This’s what I heard about myself from people around me ;)

Anyways I compiled this PDF because I noticed that there are no officially provided notes from VU for CS601. But there’s a reading section after every lecture. So, I compiled it by copying & pasting that reading section stuff including pics. I hope that this will save student time during learning as well as it’ll save them from headache during exams’ seasons which they used to get due to leaping around the whole lecture sections on VULMS in exams season to revise the course content in a short period of time.

I didn’t not only copy and paste the whole lectures to compile these notes, but also rectified some structural errors that were in reading section there. Also added some extra point(s) under the heading of FYI (i.e. For Your Information), these points would be helpful to students and VU as well !!

NOTE:

There’s no copyright infringement intended. All the stuff that I copied & pasted here belongs to VU CS601 reading sections and VU is the institute who deserves the credit for this.

I just invested my time in compiling these notes for pubic (students) welfare. If you find these notes

related to computer sciences in PDF, video, audio, and other formats.

Regards · Wishing you the best for your studies · Lecture # 1

Welcome to the exciting world of Data Communication. This foundational course has been carefully designed to equip undergraduate students with a broad comprehension of the essential principles and techniques that serve as the foundation for contemporary communication systems. Today's world is characterized by rapid technological advancements, and proficiency in transmitting, receiving, and exchanging data effectively and securely holds the utmost significance. This course is an entry point for students to delve into the complex system of technologies and protocols that provide uninterrupted communication on a global scale.

During this course, students will explore the fundamental principles of data communication, covering the ideas of data transfer, networking technologies, and internet protocols. Students will acquire knowledge and understanding of the essential hardware and software components that constitute the foundational infrastructure of contemporary communication networks. By learning a foundational grasp of data encoding and delving into advanced subjects like network security and wireless communication, students will develop the requisite knowledge and abilities, to effectively traverse the intricate nature of the digital communication domain.

FYI: This lecture is just an introduction to the course. Nothing special to learn here.

Lecture # 2

Communication: Sharing of Information (Local or remote).

Telecommunications: Communication at a Distance (includes telephony, telegraph, and television etc.)

Data communications: Exchange of data between two devices via some form of transmission media.

Lecture # 3

Effectiveness of a Data Communication System:

The effectiveness of a Data Communication System depends on the following factors:

Delivery:

When data is sent from one place to another correctly and successfully, this is called delivery.

Accuracy:

When data is sent, it must be accurate, which means that there must be no errors.

Timeliness:

For data to be considered timely, it must be sent within a reasonable amount of time.

Jitter:

The difference in packet arrival times in a network, which affects how consistently data is sent at regular intervals, is called jitter.

Lecture # 4

FYI: This lecture covers the same reading content as of previous lecture i.e. lecture # 3, but only includes this extra picture.
