Computer Networking has impacted almost all aspects of life in this modern world. Imagining a “World without networking” is truly a nightmare. In today’s contemporary world, innovations and research are being carried out to bring all things on the internet to ease up the lifestyle and living. Undeniably, networking is the core of the internet. Security is certainly an inevitable entity of today’s sophisticated world. It can be observed that the power of networking technology also has a series of side effects, vulnerabilities, threats, attacks, intrusion, security breaches, and all that are unethical. Whenever a new security measure is introduced on the computer/internet, parallelly the attack to break the security also emerges equally powerfully. If security is compromised then banking, defense, e-commerce, email, and almost all the sectors that rely on the internet will witness an apocalypse. Therefore cryptographic techniques and securing the network remain immortal either at the improvised level or new level. The purpose of the lecture series will provide learners with the fundamental concepts of cryptography, number theory, modern ciphers, public-key cryptography, hash functions, digital signatures, security practices, system security, email security, IP security, and web security. This series is mainly intended for UG students to learn about various cryptographic techniques and network security concepts and practices. We have taken utmost care to present this lecture series free from typographical and other errors. If any inadvertent error is found, the same may kindly be ignored and corrected based on the discretion of the learner. We are always ready to accept constructive criticisms for the betterment.

Crypto Currency trading course: Learn about Crypto Currency trading

A cryptocurrency (or crypto currency) is a digital asset designed to work as a medium of exchange that uses strong cryptography to secure financial transactions,
control the creation of additional units, and verify the transfer of assets.
Cryptocurrencies use decentralized control as opposed to centralized digital currency and central banking systems.

The decentralized control of each cryptocurrency works through distributed ledger technology, typically a blockchain, that serves as a public financial transaction database.

Bitcoin, first released as open-source software in 2009, is generally considered the first decentralized cryptocurrency.
Since the release of bitcoin, over 6,000 altcoins (alternative variants of bitcoin, or other cryptocurrencies) have been created.
