Using the information below, CPU X = 0.3 ms (the average time to execute 1,000 instructions)Drive A = 0.7 ms (average data access speed)Drive B = 4 ms (average data access speed)Drive C = .03 ms (average data access speed)Calculate I/O access speed using this CPU and each of the disk drives as they evaluate the following track requests in this order: 16, 4, 9, 16, 29, 31, 5. Then, in each case, calculate the access speeds after the track requests are reordered and rank the three disk drives before and after reordering.

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.
