PPP
PPP (Point-to-Point Protocol) is a basic but important method for connecting computers over phone lines or internet connections. Think of it like creating a secure tunnel between two points. When you see this on a resume, it usually means the person has experience with setting up or managing internet connections, especially older or specialized business connections. It's similar to how a private road connects two places directly, ensuring safe travel of information between them. While newer technologies exist, PPP is still used in many business settings, especially in remote locations or where very reliable connections are needed.
