About Me

Hello there! 👋 I'm Chetan Sharma, a passionate student pursuing a Bachelor's degree in Computer Science at AKTU. Currently in my second year of B.Tech, my journey in the realm of technology has been both exciting and enriching.

A Student's Initiative:

In the hustle of exams and the quest for knowledge, I stumbled upon an idea — why not compile my study notes and share them with fellow AKTU students? And so, in January 2024, the "AKTU FREE NOTES" blog was born. The goal is simple: provide easy-to-comprehend, freely accessible notes for subjects like DSTL, COA, and DSA.

Why Free Notes?

Having experienced the challenges of exam preparation firsthand, I recognized the value of concise and clear study materials. These notes not only serve as a personal aid during exams but also extend a helping hand to other AKTU students navigating the intricate world of computer science.

What to Expect:

Completely Free Resources: Access high-quality educational content without any cost or subscription fees.
Tailored for AKTU Students: Notes designed with students in mind, ensuring clarity, accuracy, and relevance to AKTU courses.
Continuous Learning Journey: Join me in exploring the diverse facets of computer science through simplified and comprehensive notes.

Happy learning! 🚀

Tools and Methods Used In Cyber Crimes | Proxy Servers and Anonymizers | AKTU B.Tech 2nd year Cyber Security Unit 3 Notes

Introduction to Tools and Methods in Cybercrime Cybercrime Landscape: The cyber landscape is evolving rapidly, and so are the tools and methods employed by malicious actors. Understanding these elements is essential for defending against cyber threats. Here, we'll delve into three prominent areas of concern. Proxy Servers Proxy Server Basics: Definition: An intermediate server between a user's device and the internet. Manages requests and responses between the user and websites. Functionality: User's request ➔ Proxy server ➔ Website. Website's response ➔ Proxy server ➔ User's device. Benefits of Proxy Servers: Anonymity: Conceals user's identity by presenting the proxy's IP address to websites. Security: Acts as a buffer against malware, viruses, and online attacks. Access Control: Configurable to block or allow specific types of traffic, enhancing control. Types of Proxy Servers: Forward Proxy: Sits between client and internet. Forwards client's requ...

Data Structure Unit 4 | serching | AKTU Free Notes Online.

Concept of Searching: Searching is the process of finding a particular item or element within a collection of items. It involves examining each element in the collection until the desired item is found. Sequential Search: Also known as linear search. Involves checking each element in a list or array one by one from the beginning until the target element is found or the end of the list is reached. Simplest form of searching. Works well for small lists or unsorted data. Time complexity is O(n) where n is the number of elements in the list. Index Sequential Search: Enhances the efficiency of sequential search by using an index. The index is a data structure containing pointers or references to the elements in the main data structure (e.g., array). The index allows for quicker access to elements, reducing the number of comparisons needed. The search first checks the index to locate the block where the target element might be, then performs a sequential search within that block. Suita...
