3. User Datagram Protocol (UDP) is often used for audio or video streaming services. UDP includes very few protocol mechanisms—for example there’s no “handshake” dialogue, making the signal less reliable than TCP—and performs little in the way of error checking and few corrections in data transfer. Why would these characteristics contribute to it being preferred over TCP for streaming?

Python. primary u. s. interstate highways are numbered 1-99. odd numbers (like the 5 or 95) go north/south, and evens (like the 10 or 90) go east/west. auxiliary highways are numbered 100-999, and service the primary highway indicated by the rightmost two digits. thus, the 405 services the 5, and the 290 services the 90. given a highway number, indicate whether it is a primary or auxiliary highway. if auxiliary, indicate what primary highway it serves. also indicate if the (primary) highway runs north/south or east/west.
