Integrity: ensuring that information is not altered (did not change). Availability: ensuring info can be used by authorized parties when needed (people can get to it). Pattern Recognition correct answersObserving patterns, trends, and regularities in data. Involves finding the similarities or patterns among small, decomposed problems that can help us solve more complex problems more efficiently. Abstraction correct answersIdentifying the general principles that generate these patterns. The process of filtering out (ignoring) the characteristics of patterns that we don't need in order to concentrate on those that we do. Enables us to navigate complexity and find relevance and clarity at scale. Algorithm Design correct answersDeveloping the step by step instructions for solving this and similar problems. Determining appropriate steps to take and organizing them into a series of instructions (a plan) for solving a problem or completing a task correctly. Decomposition correct answersBreaking down data, processes, or problems into smaller, manageable parts. Involves breaking down a complex problem or system into smaller parts that are more manageable and easier to understand. Encryption correct answersThe cryptographic transformation of data (called "plaintext") into a form called "ciphertext". Decryption correct answersA transformation that restores encrypted data to its original state.
