Paljud tarkvaralitsentsid on üsna piiravad, kui tegemist on selle, kuidas ja kus saab programmi installida, kuid kui palju neid programme on, siis millist tüüpi seadmeid nad on installitud? Tänane SuperUseri Q & A postitus on vastuseks uudishimulikule lugeja küsimusele.
Tänane küsimuste ja vastuste seanss jõuab meile viisakalt SuperUserini - Stack Exchange'i ja kogukonnapõhiste Q & A veebisaitide rühmitusse.

Küsimus
SuperUseri lugeja Abhi soovib teada, kas tarkvara saab lauaarvuti ja sülearvuti vahel eristada:
A license for CPU-intensive software like Pix4D says that it can be installed on two devices, but with one condition. Reading the fine print, it seems that one device can be a full-processing desktop/workstation whereas the second one must be a laptop or mobile device.
How would the software know what type of device it is installed on? Are there giveaways in the hardware specifications for determining something like this (i.e. the presence of a battery)?
Given that the software is fully functional on both devices, would this condition become irrelevant if I just buy a high-end laptop which is just as fast as the desktop?
Kas tarkvara saab lauaarvuti ja sülearvuti vahel eristada?
Vastus
SuperUseri toetajad abnev ja Technik Empire on meie jaoks vastus. Esiteks üles, abnev:
On Linux, you can run the following command:
sudo dmidecode –string chassis-type
On a laptop, this will return laptop, notebook, portable, or sub-notebook (depending on the manufacturer).
For Windows, refer to the following TechNet documentation to determine your computer chassis type: Identifying the Chassis Type of a Computer
Järgneb Technik Empire vastus:
To add to the other answer here regarding Linux, Windows software can also access this information through various provided WinAPI methods/objects. One such example is Win32_ComputerSystem, which among others, has members like:
Possible values include:As for how Windows knows this, while I cannot say with certainty because I presently lack both the Windows source code and any official documentation links, I would say it is a simple matter of the hardware ID’s within the computer giving this information away to the operating system.
Since Windows has a massive partner network that submits their drivers directly to Microsoft (for driver updates via Windows Update and “standard” drivers to include with installation media), it is pretty easy for Windows to figure out precisely what kind of computer you have it installed on. Just by the CPU ID alone, you could determine whether it is a desktop computer or a laptop.

Windowsil on sisseehitatud tulemüür, mis blokeerib sisenevad ühendused. Kui programm soovib serverit tegutseda, küsib Windows teid. Mõned geeksid ei meeldi sisseehitatud tulemüürile, kuna see ei paku väljaprintimiseks samu viipasid.
