Content filtering is a technology used to restrict or control the information that users can access on the internet. It works by analyzing data and blocking or allowing content based on specific criteria, such as keywords, categories, or user preferences. This is commonly used in schools, workplaces, and homes to protect users from inappropriate or harmful material. Many organizations implement content filtering to enhance security and productivity. For example, firewalls and web filtering software can prevent access to malicious websites or social media during work hours. This helps create a safer online environment while ensuring that users focus on relevant tasks.
