Online Training Master Class : TCP/IP Mechanics from Scratch to Expert[Note :This course is under development, I am still adding content to this course. Pls be informed before enrolling into this course]This is Master Class course on TCP/IP protocol – Transmission Control Protocol. Since it is Master Class course, this course discusses the internal design and functioning of complex transport layer protocol – TCP. Almost all traffic on internet today is transported by TCP protocol. TCP, as where it stands today, mature and solid, is the result of over 25 yrs of research by network gurus. TCPis complicated and difficult to understand, therefore i have paid utmost attention to present the concept in most simplest way as possible without any loss of information.In this course, we unwrap internals of TCP and try to understand how it works and why it is so designed. So, be ready and place yourself in first gear ! TCP is difficult to understand and confusing if not done in the right way. In this course, I shall be covering all aspects of TCP internal functioning STEP BY STEP with beautiful diagrams, Assignments, Questions and exercises. At no point you shall be left with doubts is my promise. There is no programming in this course. This is a littleAdvancedCourse, if you are absolute beginner in networking, I would recommend you to first enroll in my other course “Networking course – Network Concepts and Programming from Scratch” and cover important sections on L2 routing, L3 routing, and Transport Layer at-least before jumping into this course. If you are already familiar with this much networking basics, then you are all set to sail through this course.Table Of Contents:Section 1 : Basics1. Agenda of the course2.

Investing in yourself through Learning
As a society, we spend hundreds of billions of dollars measuring the return on our financial assets. Yet, at the same time, we still haven’t found convincing ways of measuring the return on our investments in developing people.
And I get it: If my bank account pays me 1% a year, I can measure it to the penny. We’ve been collectively trained to expect neat and precise ROI calculations on everything, so when it’s applied to something as seemingly squishy as how effectively people are learning in the workplace, the natural inclination is to throw up our hands and say it can’t be done. But we need to figure this out. In a world where skills beat capital, the winners and losers of the next 30 years will be determined by their ability to attract and develop great talent.
Fortunately, corporate learning & development (L&D), like most business functions, is evolving quickly. We can embrace some level of ambiguity and have rigor when measuring the ROI of learning. It just might look a little different than an M.B.A. would expect to see in an Excel model.
