Tag: Operating System

An operating system (OS) is system software that manages computer hardware and software resources and provides common services for computer programs. The operating system is a component of the system software in a computer system. Application programs usually require an operating system to function.

Time-sharing operating systems schedule tasks for efficient use of the system and may also include accounting software for cost allocation of processor time, mass storage, printing, and other resources.

For hardware functions such as input and output and memory allocation, the operating system acts as an intermediary between programs and the computer hardware, although the application code is usually executed directly by the hardware and frequently makes system calls to an OS function or is interrupted by it. Operating systems are found on many devices that contain a computer – from cellular phones and video game consoles to web servers and supercomputers.

Examples of popular desktop operating systems include Apple OS X, Linux and its variants, and Microsoft Windows. So-called mobile operating systems include Android and iOS. Other classes of operating systems, such as real-time (RTOS), also exist.

Google tinkers with Android O to foil ransomware

In Android, apps aren’t supposed to be able to interfere with the normal behavior of other apps or the device itself.

But ransomware is notorious for taking over other apps and encrypting data, and it can even block the uninstall command.
It’s been a long-standing problem for Google’s Android mobile operating system.“Ransomware does everything opposite of what the Android security model says apps should do,” says Android security team malware analyst Elena Kovakina. Google is tackling the ransomware problem on Android by beefing up app protections, deprecating certain APIs, and removing functionality, she says. Google has made antimalware improvements in the current Android Nougat, and more are slated for the forthcoming Android O.To read this article in full or to leave a comment, please click here
