Data Encryption:**

Here are the definitions for the terms you've provided: 1) Data Encryption: Data encryption is the process of converting data into a coded format to prevent unauthorized access. It transforms readable data (plaintext) into an unreadable format (ciphertext) using an algorithm and an encryption key. Only individuals with the correct decryption key can convert the ciphertext back into plaintext. 2) Password: A password is a secret word, phrase, or string of characters used to authenticate a user's identity and grant access to a computer system, network, or protected resource. It serves as a primary security measure to verify that the user is who they claim to be. 3) Biometric Authentication: Biometric authentication is a security process that verifies a user's identity by measuring and analyzing unique biological or behavioral characteristics. Examples include fingerprints, facial recognition, iris scans, and voice recognition. 4) AI (Artificial Intelligence): Artificial Intelligence (AI) refers to the simulation of human intelligence in machines that are programmed to think and learn like humans. AI systems can perform tasks such as problem-solving, learning, decision-making, and understanding language. 5) IoT (Internet of Things): The Internet of Things (IoT) is a network of interconnected physical objects embedded with sensors, software, and other technologies that allow them to connect and exchange data over the internet with other devices and systems. These objects range from everyday household items to industrial tools. 6) Digital Divide: The digital divide refers to the gap between individuals, households, businesses, or geographic areas at different socioeconomic levels with regard to both their access to information and communication technologies (ICTs) and their use of the internet for a wide variety of activities.
