What is the difference between iOS, iPados, and macOS?
Speaking of iPhone operations system (OS), "iOS" is different from "iPados" for iPad OS, which has a similar look, such as icon design.The function is different because the name is different...There are certainly different points, but these two OSs are "close -to -related species" that have recently been branched.
In the first place, iOS was born as an "iPhoneOS" developed based on OS (MacOS, then Mac OS X).The program and the base part at the core of the OS, such as kernels (the name is "Darwin"), is common, and many program components (libraries/frameworks), including drawing mechanisms and sound mechanisms, are optimized for iPhone for iPhone.The system was realized in the form of a unique function.
In other words, iOS was born as a "brother" of MacOS, but eventually the development order is reversed.As the word "mobile first" says, Apple has begun to prioritize iOS enhancement and new functions.For example, fingerprint authentication "Touch ID" or voice assistant "Siri" is the first technology introduced on iOS and later adopted in MacOS.However, there are large differences in hardware such as SoC, and both are not compatible.
On the other hand, iPados is an iOS "twin brother".Initially, the iPad was working on iOS itself, but it became independent as an iOS 13's announcement, and it has a unique function suitable for tablets, with many of the iOS functions.rice field."SideCar" is an example of handwriting functions using Apple Pencil, which allows iPad to be used as a second display of Mac.It is also important to have high compatibility with iOS and apps because it is equipped with a similar SoC.
For that reason, MacOS was a bit far from the relationship between iOS and iPados, but the situation changed after the M1 processor Mac appeared in 2020.By adopting a SOC that is the same as the iPhone/iPad on the Mac, the iOS/iPadOS application is now possible on MacOS, albeit not everything.In the future, the relationship between the three must be closer.
