What exactly does the IOS system mean, what does the ios system mean

iOS is a mobile operating system developed by Apple Inc.

Apple first announced the system at MacWorld on January 9, 2007, and was originally designed for the iPhone, and later applied to products such as iPodTouch, iPad, and AppleV. iOS, like Apple's macOS operating system, is a Unix-like commercial operating system.

On September 22, 2018, Apple Inc. of the United States secretly added iPhone-based to its latest operating system

At the Worldwide Developers Conference, Apple released a new version of the iOS operating system.

iOS (formerly known as iPhoneOS) is Apple's proprietary mobile operating system for its mobile devices, providing an interface for many of its mobile devices, including iPhone, iPad and iPod touch.

iPhoneOS has been renamed iOS since iOS 4, and it is the second most popular mobile operating system in the world after Android, and its market share has risen to about it, but it is still far below Android's.

iOS was first introduced in 2007 with the iPhone and expanded to support other Apple devices such as iPod Touch (September 2007) and iPad (January 2010). As of January 2017, Apple's AppStore has more than 2.2 million iOS apps, of which 1 million are native apps for iPad. The total number of these mobile apps** has exceeded 130 billion.

The user interface of iOS is to use multi-touch for direct operation. Interface control elements include sliders, switches, and buttons. Controls on the user interface include swipe, tap, twist and reverse twist.

All of these are specifically defined in the iOS operating system and its multi-touch interface. The built-in speed sensor can be used by some applications to respond when the device shakes (a common result is to restore commands), or to rotate in 3D (commonly when switching between portrait and landscape screen modes). Apple has received great appreciation for integrating accessibility features into iOS to enable users with visual or hearing impairments to use their products correctly and without barriers.

Major versions of iOS are usually released once a year. The current version is iOS 12, which was released on September 17, 2018. It is available on all iPhone 5s and later with a 64-bit processor, iPad (5th generation), iPad Air and later, all iPad Pro models, iPad mini2 and later, and iOS devices with iPod Touch (6th generation).

Originally, this system was called iPhone OS, because iPad, iPhone, and iPod Touch all use iPhone OS, so at Apple's Worldwide Developers Conference in 2010, it was announced that it would be renamed iOS (iOS is a registered trademark of Cisco's network device operating system, and Apple's name change has been authorized by Cisco).

Security for iOS:

From the moment you turn on your device, iOS provides you with built-in security. iOS is designed with low-level hardware and firmware features to protect against malware and viruses; It is also designed with high-level OS functions to help ensure security when accessing personal information and corporate data.

To protect your privacy, apps that get location information from your calendar, contacts, reminders, and ** must get your permission first. You can set up a passcode lock to prevent unauthorized access to your device, and configure it to allow the device to delete all data after multiple failed passcode attempts.

The password also automatically encrypts and protects your stored emails, and allows third-party apps to encrypt the data stored for them. iOS supports encrypted network communication, which can be used by apps to protect sensitive information in transit.

If your device is lost or stolen, you can use Find My to locate your device on a map and remotely wipe all your data. Once your iPhone is lost, you can also recover all the data that you had saved from the last time.
