PKB, or Personal Knowledge Base, is a system designed to help individuals organize and manage their knowledge and information. It allows users to store notes, ideas, and resources in a structured way, making it easier to retrieve and utilize this information when needed. PKBs can be digital or physical, and they often incorporate various tools and methods for effective information management. Many people use PKBs to enhance their learning and productivity. By creating a personalized repository of knowledge, users can track their thoughts, research, and projects over time. This approach fosters better understanding and retention of information, ultimately supporting personal and professional growth.
