The extent to which an operating system is recognized depends on how many devices using that operating system are sold on the market and by how many users.
Back to your question, because of the differences in hardware platforms, frames, and therefore the installation and setup of the operating systems of flat screen TVs and computers (of course newer flat screen TVs now use Android, but there are still differences), it is not possible to compare and contrast them in a general way.
Generally oriented to portable devices or portable devices with the same needs of electronic devices, because of its relatively simple and fixed functions, so compared to the PC operating system, they use the operating system to be much simpler, we usually call the embedded operating system, this kind of equipment, including video players, PDAs, inventory machines, electronic scales with data storage, as well as some medical equipment and scientific analyzers and so on. The operating system of these devices, usually installed and set up in no more than the use of USB, serial cable using a computer through a special program to write the operating system software and data to the memory of the electronic device, or directly using a USB disk specified format or a special key to enter the automatic brush to complete the installation and setup. The amount of data from a few megabytes, tens of megabytes, up to a few hundred megabytes, unlike the PC's operating system can easily be several G, so the installation of the operating system does not require a CD-ROM.
Embedded devices are usually built-in hardware, there will be no frequent replacement of parts, modify hardware parameters, etc., while the PC computer peripheral hardware variety, and a variety of different types of equipment, equipment produced by different manufacturers are to be assembled together to use, parameter settings, in the hardware based on the operation of dozens of even hundreds of different kinds of software written by people, the complexity of its far higher than the case of embedded devices, coupled with the fact that the PC computer operating system can be used for a variety of purposes, including the installation of the operating system, the installation of the operating system does not require CD-ROM. The complexity is much higher than in the case of embedded devices, coupled with viruses and Trojan horses, it is not difficult to understand why the operating system of PC computers is often problematic and prone to damage.
The last one, Trojan horse and virus will be with the popularity of electronic devices and the popularity of the emergence and popularity of, such as now has appeared in many running on the Android system cell phone Trojan horse, PC computer running on the various applications of thousands of PC computers, the PC power on and networking time is long, and the use of frequent, in addition to viruses and Trojan horse and the back of the economic and commercial interests are closely related to the virus and the Trojan horse, and so the PC virus and Trojan flooded, and the reverse is the case of the PC computer operating system is often damaged. The virus and Trojan horse on the PC are widespread, while on the other hand, embedded in this type of equipment to use a relatively small number of users, the frequency of use is not high, and economic interests are rarely linked, naturally, there is no or very little.
As long as the use of good electronic equipment, can achieve your purpose, to meet your needs. You don't have to worry about this, just feel free to use it!
