Your smartphone is a computer. It's actually very powerful and just like anyone with a secondary school education should know, it is divided into hardware and software.

We talked about the hardware to death i.e SoC, battery, display, speakers etc which are the physical parts of the phone that you can interact with.

Today let's do Software: Software is a set of instructions, data or programs used to operate computers and execute specific tasks. Software is the part of the computer that you cannot touch physically.

Most computers don't understand human language, they have machine language which essentially is binary. So how do we communicate with a computer then?

The answer is an Operating system. What is an Operating system? An operating system is a program that manages the computer hardware (and software). It translates human commands to machine language and provides the platform for apps to run. It is the middle man between you the user and the hardware in your hand. It is also said to be "taskware" in that it manages how applications have access to limited hardware resources.

In simple English, if you have an Octa-core CPU with 3GB RAM, when you put on your phone, the operating system (e.g android) will assign itself a certain amount of RAM space e.g 1GB RAM and you'll be left with 2GB of RAM space. If you have FB, WhatsApp and SMS apps open, the Operating system assign each of them a space in the RAM memory, whilst the CPU will take information of where they're stored in the RAM and keep it in a small address box inside it self called registry. It does so, so that it can easily retrieve the information if need be. If you were to open PUBG for example, which may take up to 1.5GB of RAM space, the OS will force close the apps you have opened previously from the RAM and the CPU will delete such an address from the registry as it no longer exists in the RAM. This is done to create RAM space for PUBG to be able to run smoothly.

The OS supports apps and regulates how they use the hardware. It also helps you interact with the apps and translates your commands to the language that the apps can understand e.g. pressing the shoot button in PES 20 and the player takes a shot.

Apps

OS

Hardware

There are generally two categories of Operating systems for Smartphones:

1. Closed source: This is when the user is not allowed to modify the OS
a. iOS
b. KaiOS

2. Open source: This is when the user is free to modify the OS to his tastes.
a. Android
b. Fuchsia
c. SailfishOS
d. Tizen

All android phones for example run on Android OS. Android OS is a touchscreen based OS. It is mostly a set of codes (think of those green lines of codes in the movie Matrix). For you to understand those codes, it has to be presented in a form that we can see and understand. That form is what we call a User Interface or UI.

A mobile UI is the user interface on a mobile device, usually including a touchscreen display and all the other elements of the device that allow the user to interact with it.

Google allows the the individual companies to design their mobile UI in any way they like and run such software on top of the android OS. Popular UIs include
1. Android one
2. Android Go (for 1GB RAM devices)
3. One UI (Samsung)
4. EMUI (Huawei)
5. MIUI (Xiaomi)
6. Oxygen OS (1+)
7. Colour OS (Oppo)
8. HiOS (Tecno)
9. XoS (Infinix)

Last but not least, the Apps.
A mobile application, most commonly referred to as an app, is a type of application Software (group of codes) designed to run on a mobile device, such as a smartphone or tablet computer. Mobile applications frequently serve to provide users with similar services to those accessed on PCs. Apps are generally small, individual software units with limited function. Each appvprovides functionality such as a game, calculator or mobile web browsing.
Mobile application ranges from Nativeapps, Webapps, Gameapps, businessapps, educational apps, security and anti-malwareapps etc.

Apps can and should be downloaded from Playstore or the Apple store.

Lovely....

But why talk about the RAM without the ROM where the data is stored or held.....

When CPU want to process an application, it fetches that data from where it is in the ROM and takes it to the RAM. This process of course is facilitated by the OS.

From there the CPU will have two lines of communication with the RAM, one for the Apps data and another for Apps address. The code of the app needed to run has already been given a space in the RAM so there's no need for the ROM anymore.

The ROM is just for storage. Like to keep the app till you need to use it.

Android one is Google's own UI designed by their own software engineers to run on the Android OS. This UI cannot be modified by any other third party except by Google themselves. Phones on the Android one programme get their updates directly from Google and are guaranteed at least two generations of software update e.g. Nokia X5 from Android 8.0 Oreo to Android 10.

Android Go is a light version of the Android OS as well as UI reduced so as to be able to run on low end processors which cannot carry the heavy load of processing the full android software. This OS with such processors are only designed to support lite versions of apps like FB lite, messenger lite, YouTube go etc.

Yeah of course bro. I asked because you listed it among the UIs from OEMs.

BenDanor:

I understand.

Google gives away the software to the OEMs who are under the Android one and Android Go program. it is these companies that install these softwares on their phones, Tecno bundles HiOS with Android Go but ultimately, the software still belongs to Google and not the companies.

If I were to ask you, when you say "Ok Google" and the phone wakes up, and you give it a search instructions in English, how does it converts that English to machine language?

Abi has Google predefined what you want to ask the AI?
