Protect Data:
In cryptography, encryption is mainly used to **protect data by converting it into a coded format** that can only be read by someone who has the decryption key. This ensures the confidentiality and security of the information, preventing unauthorized access and ensuring that sensitive data remains private during storage and transmission.

Router: A router is the device specifically designed to connect different networks. Routers are responsible for forwarding data packets between networks, typically used in connecting a local area network (LAN) to a wide area network (WAN), such as the internet. They analyze the destination IP address of a packet, determine the best route for it to travel, and direct it accordingly. Routers can also connect multiple networks within an organization, allowing for communication and data transfer between different segments of the network.
