Three different learning styles in machine learning algorithms:

1. Supervised Learning

Input data is called training data and has a known label or result such as spam/not-spam or a stock price at a time.

A model is prepared through a training process in which it is required to make predictions and is corrected when those predictions are wrong. The training process continues until the model achieves a desired level of accuracy on the training data.

Example problems are classification and regression.

Example algorithms include: Logistic Regression and the Back Propagation Neural Network.

2. Unsupervised Learning

Input data is not labeled and does not have a known result.

A model is prepared by deducing structures present in the input data. This may be to extract general rules. It may be through a mathematical process to systematically reduce redundancy, or it may be to organize data by similarity.

Example problems are clustering, dimensionality reduction and association rule learning.

Example algorithms include: the Apriori algorithm and K-Means.

3. Semi-Supervised Learning

Input data is a mixture of labeled and unlabelled examples.

There is a desired prediction problem but the model must learn the structures to organize the data as well as make predictions.

Example problems are classification and regression.

Example algorithms are extensions to other flexible methods that make assumptions about how to model the unlabeled data.

Programming languages and their uses in Ethical hacking :

Programming languages are essential tools for ethical hackers. They are used for tasks such as vulnerability testing, penetration testing, and developing exploits. Here are some programming languages that are commonly used in ethical hacking and their specific uses:

Python: Python is a high-level programming language that is easy to learn and widely used in the field of cybersecurity. It is used for tasks such as penetration testing, reverse engineering, and scripting. Python has a large community of developers who create and maintain libraries that can be used for security purposes, such as Scapy for packet manipulation, PyCrypto for encryption and decryption, and BeautifulSoup for web scraping.

Ruby: Ruby is another high-level programming language that is popular in the cybersecurity community. It is used for developing exploits and automating tasks. Metasploit, one of the most widely used penetration testing tools, is written in Ruby.

C/C++: C and C++ are low-level programming languages that are used for writing exploits and developing rootkits. They are also used for reverse engineering and vulnerability testing. Many of the tools used in ethical hacking, such as Nmap, Wireshark, and Tcpdump, are written in C/C++.

JavaScript: JavaScript is a popular scripting language that is used for web application security testing. It is used for tasks such as cross-site scripting (XSS) and cross-site request forgery (CSRF) testing. Many web-based security tools, such as Burp Suite, are written in JavaScript.

Bash: Bash is a shell scripting language that is used for automating tasks and creating custom scripts. It is commonly used for tasks such as password cracking and network scanning.

SQL: SQL is a database programming language that is used for exploiting and testing SQL injection vulnerabilities in web applications.

In addition to these languages, there are many other programming languages that can be used in ethical hacking, such as Perl, PHP, and Java. The choice of programming language will depend on the specific task at hand and the preference of the individual ethical hacker.

❇️ How to Find Server’s IP Address of Any Website
βž–βž–βž–βž–βž–βž–βž–βž–βž–βž–βž–βž–βž–βž–

πŸ’  Using Command Prompt For Windows

πŸ‘‰ In this method essentially ping commands work for us to locate the IP address of any site. Actually, the ping command works on ICMP protocol which is made for servers address. Hence this command uses to locate the server address.

πŸ”ΉStep 1: Click on the Start button and type CMD. Open CMD from the list.

πŸ”ΉStep 2: Now you will see an elevated Command Prompt Window.

πŸ”ΉStep 3: Type ping Site name (for ex-ping Kalilinux.com ).
And press Enter.

βœ… Now, this will show you the IP address of the site and all trip details of the site location.

πŸ’  Using Terminal In MAC Or Linux

πŸ‘‰ The terminal is like the command prompt but it is for Linux and macOS. In this, we can use the same command that we did in CMD. Now in this terminal, you will lookup for the Ip address of any site using a simple command.

πŸ”ΉStep 1: Open terminal by a pressing CTRL+ALT+T ok keyboard at once.

πŸ”ΉStep 2: Now type ping -c1 Sitename (for ex:- ping -c1 kalilinux.com).

βœ… The above command will display the IP address of the entered website.
