Decoding the Digital World: Understanding How the Internet Works in Everyday Life

NAT is a method used by routers to translate a public IP address used on the Internet into a private IP address used within a local area network (LAN) and vice versa. This is necessary because the number of available IPv4 addresses is limited. NAT allows multiple devices on a private network to share a single public IP address.

Internet Security Protocols

Internet security is crucial in protecting data during transmission. Protocols such as Secure Sockets Layer (SSL) and its successor, TLS, provide encryption and authentication to secure data communications over networks. They are most commonly used for securing transactions in web browsers (as part of HTTPS).
