Basic Electronics

Electronics plays a vital role in today's era of Technology. A very basic component 'Diode' was invented in the year 1919 and since then the evolution of the world of Electronics has beautified the face of Technological Researches and Developments.

This course mainly focuses on the fundamental ideas of Basic Electronics and Computer Programming by providing wide exposure to the basic concepts of Electrical and Electronics Engineering along with the dynamic implementations of these concepts into everyday life.

About the Course:

The course focuses on the Basic Electronics and Computer Programming subject by means of providing Video Lectures and Notes of various topics covered. The topics covered include Electronic Components, PN Junction Diodes and Rectifiers, Transducers and Basics of Digital Electronics. The course then extends its scope to the wide range of Problem Sets, Question Banks, Quizzes, University Questions to help students to gear up for their exams.

Computer Programming

Advent of computers has brought in path breaking revolution in all fields of today's era. With computer programming, it has become possible to reduce human efforts on otherwise tedious tasks.

This is a course on programming in C language coupled with other programming and computer fundamentals that is essential for every programmer. It also covers numerous Problem Sets, Multiple Choice Questions, Quizzes, University Questions , etc which would help a student for his exam.

About the Course:

This course covers C programming fundamentals with detailed and relevant examples for each C program concept. It also has topics under Analysis of Algorithm, Programming Languages, Program Documentation, Operating Systems, Testing and Debugging, Number system and Computer Architecture. The course then extends its scope to the wide range of Problem Sets, Question Banks, Quizzes, University Questions to help students to gear up for their exams.
