# M-Healthcare Model: An Architecture for a Type 2 Diabetes Mellitus Mobile Application
## 2 Analysis
### Mobile Technology and Operating System  
A mobile phone is a portable electronic device that functions like a regular phone and can be moved over a wide area. While mobile phones currently use a combination of wireless transmission and traditional telephone circuit switching, packet switching is used in parts of the mobile phone network, especially for Internet access and WAP services [22]. Mobile phones, or \"cell phones\", are electronic communication devices that have the same basic functionality as traditional landlines, but they can be carried anywhere (mobile) and do not need to be connected to a phone network using a cable (wireless) [23]. The mobile operating system is the primary software that directly manages and controls the hardware, and also manages and controls other software so that it can function (Table 6). Therefore, the mobile operating system is responsible for manipulating the various features and functions available on mobile devices. tasks, keyboards, WAPs, emails, text message scheduling, synchronization with other applications and devices, music playback, cameras, and control features [24]. In addition to the ability to control mobile phone hardware and software resources such as keyboards, screens, phonebooks, batteries, and network connections, the operating system controls all applications to run consistently and consistently. The operating system needs to be flexible so that software developers can easily create sophisticated new applications [25]. \begin{table}

As a handheld operating system, iOS works the same as Android, developed by Google. Basically, the function of iOS is to design the iPhone so that it can be operated by the user. iOS can create a bridge that connects the interaction between the user and the iPhone hardware. iOS is responsible for interpreting user commands for applications on the iPhone so that you can interact with, move, or activate hardware features. Conveniently, iPhone users can take pictures and videos, listen to music, and make phone calls. This is because the iOS feature successfully receives these commands and interprets them for the iPhone hardware. As _Lifcewire_ reports, without iOS, you cannot use the iPhone hardware or its functions. iOS features are generally the same as those on Android, but there are some differences. \begin{table}

[PERSON]} & \multirow{5}{*}{Nutrition} & A nutrition application is an application that helps patients/users to find out the number of nutritional needs and nutritional status by referring to nutrition and health sciences efficiently, cheaply, and accurately, where each country has different nutritional guidelines. This is very useful because food consumption affects a person’s nutritional status. Good nutritional status or optimal nutritional status occurs when the body gets enough nutrients that are used efficiently, so as to support physical growth, brain development, workability, and general health as much as possible. A nutrition application already has a nutritional value based on a calculated formula ( nutritional standards) by accessing the database; the application can find specific numbers (food/beverage) that will be or have been consumed.
