The age one becomes a legal adult in the US is largely the age at which most children are considered adults in the world. A few countries set this age lower, but in most of the Western world, one is considered an adult at 18.
RC4 (Rivest Cipher 4). RC4 is one of the most used software-based stream ciphers in the world. The cipher is included in popular Internet protocols such as SSL (Secure Sockets Layer) and WEP (for wireless network security).C4 (Rivest Cipher 4).

The series resistors R1, R3, and R4 along with the capacitor C2 form an RC circuit that is used to trigger the 555 timer to generate and control the output frequency of device. When the voltage Vcc is applied to the top of R1, the current passes through the resistors in series to charge the capacitor C2.
