HTTPS, or Hypertext Transfer Protocol Secure, is an extension of HTTP that incorporates security measures to protect data during transmission. It uses encryption protocols, such as SSL/TLS, to secure the communication between a user's web browser and the server, ensuring that sensitive information, like passwords and credit card numbers, remains private and secure from eavesdroppers. This makes HTTPS essential for secure web browsing, particularly for websites that handle personal or financial data.

Artificial Intelligence (AI) encompasses a range of technologies and algorithms that enable machines to analyze data, recognize patterns, and make decisions based on that information. Unlike traditional programming, where explicit instructions are provided, AI systems learn from data through methods such as machine learning and deep learning. This ability to adapt and improve from experience allows AI to perform tasks ranging from image recognition to natural language processing, making it a key technology for enabling machines to learn and evolve autonomously.

A VPN, or Virtual Private Network, primarily creates a secure and encrypted connection over the internet, allowing users to send and receive data safely. This secure private connection protects sensitive information from potential threats, such as hackers or unauthorized access, especially when using public Wi-Fi networks. By masking the user's IP address and encrypting data, a VPN enhances privacy and security online, making it a vital tool for individuals and businesses looking to safeguard their internet activity.

Kotlin is widely used for Android app development because it is officially supported by Google and offers modern features that enhance productivity and code safety. Its concise syntax reduces boilerplate code, making development faster and more efficient. Additionally, Kotlin is fully interoperable with Java, allowing developers to leverage existing Java libraries and frameworks. This combination of ease of use, safety features, and compatibility with Java makes Kotlin the preferred choice for many Android developers.

Encryption transforms data into a secure coded form to protect its confidentiality and integrity. This process involves using algorithms and keys to convert readable information into a format that is unintelligible to unauthorized users. Only those with the correct decryption key can revert the coded data back to its original form, ensuring that sensitive information remains protected from unauthorized access or interception.

Blockchain technology is primarily associated with secure digital records and decentralized transactions due to its unique structure. It operates as a distributed ledger that records transactions across multiple computers, ensuring transparency and immutability. Each block in the chain contains a cryptographic hash of the previous block, linking them securely. This decentralized nature eliminates the need for a central authority, reducing the risk of fraud and enhancing security. As a result, blockchain is widely used in cryptocurrencies and various applications requiring secure and verifiable transaction records.

Two-factor authentication enhances security by requiring users to provide two forms of identification before gaining access to an account. This typically involves something they know (like a password) and something they have (like a smartphone or a security token). By adding this extra verification step, it significantly reduces the risk of unauthorized access, even if a password is compromised, thereby providing an additional layer of protection against potential threats.

WAN, or Wide Area Network, is designed to cover large geographical areas, often connecting multiple cities, countries, or even continents. Unlike LAN (Local Area Network) and PAN (Personal Area Network), which are limited to smaller, localized regions, WANs utilize various transmission technologies like leased lines, satellites, and fiber optics to facilitate long-distance communication. This makes them ideal for organizations that require connectivity across vast distances, enabling data exchange and resource sharing over extensive locations.
