Computer hacking is a term that is often used to depict the illegal or unauthorized access, modification, or utilization of information on any computer system. However, computer hacking also refers to ethical and legal practices of modifying computer systems in ways that improve their functionality and security. The basics of computer hacking are essential to understand for anyone who intends to use and protect their data in today's digitalized world. Here are some fundamental concepts of hacking that you should know.

1. Programming Languages

Programming languages are essential tools for any hacker. Experienced hackers must know multiple programming languages to write scripts that help them penetrate computer systems. For example, the C programming language is a popular choice for hacking purposes as it allows hackers to access low-level system resources.

2. Operating Systems

Hacking involves working with different types of operating systems. A hacker must have extensive knowledge of the operating system of the target computer system as it often provides critical security features that must be bypassed. Some of the most commonly used operating systems for hacking include Windows, Linux, and macOS.

3. Network Protocols

Network protocols govern the exchange of data between computer systems over a network. Hackers must have an understanding of how network protocols work to manipulate and intercept the information transfer. Some common network protocols used by hackers are TCP/IP, HTTP, FTP, and SSH.

4. Social Engineering

Social engineering refers to human manipulation tactics employed to gain sensitive information. Hackers use social engineering techniques to trick people into sharing their passwords, clicking on malicious links, or revealing confidential information. It includes impersonation, phishing, and baiting.

5. Penetration Testing

Penetration testing is the process of evaluating the security of computer networks or systems by simulating attacks. Penetration testing is an essential practice to ensure the robustness of network security. It involves hackers using various techniques to penetrate the security defenses without causing any damage.

In conclusion, the fundamentals of computer hacking are not just about illegal practices of accessing systems. Knowledge of programming languages, operating systems, network protocols, social engineering, and penetration testing are necessary skills for ethical and legal computer hacking. The understanding of these concepts can be beneficial in protecting against various cyber threats, from phishing attacks to ransomware.
