The Apple iPad was designed by a team led by British-born design executive Jonathan Ive. This sleek, ultra-thin product reflects Yves’ reverence for the genius German designer Dieter Rams. Apple’s tablet computer iPad is divided into two versions: WLAN and WLAN + Cellular. There are 8 capacities of 16GB, 32GB, 64GB, 128GB, 256GB, 512GB, 1TB and 2TB. From the appearance, the iPad is a large iPhone or iPod Touch, running the iOS (changed to iPadOS in 2019) operating system, and using an Apple processor with a main frequency of 1GHz+, supporting multi-touch, built-in Maps, calendars, videos, iTunes store, and other applications, and can also run all App Store 64-bit programs, but cannot make calls.
