1. A hard disk contains 18 platters. The data is recorded on both surfaces of each platter. Each surface has 3,000 tracks. One track can hold 3,000,000 bytes of information. What is the capacity (expressed in Bytes, Kilobytes, and Megabytes) of one cylinder? To convert bytes to kilobytes, divide the number of bytes by 1024. To convert kilobytes to megabytes, divide the number of kilobytes by 1024. To convert megabytes to gigabytes, divide the number of megabytes by 1024. What is the capacity (expressed in Kilobytes, Megabytes, and Gigabytes) of the entire hard disk? Show your computations.
