We all often think, Can computer work be done with Mobile? It would be wrong to say no, it can be said not useful. You can do a lot of things on a smartphone that people have been doing on the computer for years. I don’t talk about that but I talk about what smartphones are not useful for.
- Keyboard: You may think that you can type very fast on mobile phone but you need a full size keyboard for many professional jobs. E.g. coding.
- Multitasking: Multitasking is possible on a smartphone but it is not possible to work by opening multiple windows like a computer. (Possible on some phones but not as convenient as a computer at all)
- Interfacing: You can’t use different types of USB devices on a smartphone. (OTG supports some common devices but does not offer the same benefits as using a computer)
- Processing Power: The processor of a smartphone is RISC based and the chip architecture of almost all smartphones is ARM. The ARM processor consumes low power and is designed to do small things. The processors of low to mid range smartphones cannot run huge operating systems like computers. Moreover, there are differences in architecture. Computers typically use x86_64 architecture processors that are SISC based. They consume a lot of power and are also very powerful.
- Graphics: Smartphones use SoC (System on a Chip). This means that CPU, GPU, network and other chips are integrated in a single chip. This is done to reduce power consumption as well as to reduce the size of the motherboard. So the graphics chips of smartphones are not as powerful as the external graphics chips of computers. So you can’t do anything graphics intensive like computer on smartphone if you want. Such as: high end game play, video rendering, content creation, 3D animation etc.
- Display: The display of a computer is much larger than a smartphone and is suitable for many tasks. For example, none of us want to do coding, video editing, word / spread sheet writing, designing on small screen. These will require a large screen.
- Upgradability: None of the smartphones are user upgradable. The configuration of the phone that you buy after 2 years, even if the RAM of your device seems low, there will be no opportunity to upgrade. But all desktop computers and most laptops have user upgradability options.
- Storage: The maximum RAM and permanent memory capacity of a smartphone is much less than that of a computer. And even if you want, it is not possible to give like that in the current technology.
- Operating System: There is a huge difference between the operating system of a smartphone and the operating system of a computer. You cannot set up a server on a smartphone. (Technically you can, but many services don’t work). Also the operating system of the smartphone is designed to consume very light weight and low power. Operating systems run using few resources. The kernel and architecture are different, so you can’t install the desktop operating system directly on a smartphone.
- Application Software: Most professional software is made for computers and this is normal. You can’t find many professional Application on Mobile. Hopefully you have understood after so many discussions.
It’s not that smartphones can’t be made as powerful as computers. Of course you can. However, current technology can not offer us more. Moreover, the smartphone is a portable device in hand and in the pocket, so its structure and function have been determined depending on its use.
