When a QQ program is running on your PC, the operating system utilizes system resources such as memory, CPU usage, and network activity to track its presence. The operating system maintains a list of currently running processes, which includes the QQ program. This list is constantly updated by the operating system to monitor the status of all active programs, including QQ. Additionally, the operating system may use inter-process communication mechanisms to detect and communicate with the QQ program.
Don't know
You need how to program and you have to put in codes. Then you know how to make one.
An operating system provides an interface between the hardware and the user. It allows us to use computers without having to know how to program them.
you have to know the physics behind it then you can use it easily.

The relationship between an application program and the underlying hardware is usually shown in the form of a stack of layers as shown below: # Application # Application Programming Interface (API) # Operating System # Device Driver # Hardware Most applications need to know how to talk to the operating system - which is why the operating system will provide a set of programming libraries knows as APIs or SDKs (Software Development Kits) for programmers to use when writing applications. The APIs sit between the operating system and the running application. The running application relies on the API to perform essential tasks on the computer by telling the operating system what it wants to do - which is why a program that is written to use Windows Vista APIs will not run on an Apple Mac without some kind of emulation or help. Because there are so many different pieces of hardware, it would be impossible for an operating system to support them all (especially the lesser known devices). That's why hardware manufacturers will write device drivers for different operating systems, so the operating system knows how to talk to the hardware.
Task manager is a tool you can use to stop specified running procedure or program. It shows all running files in your system, helps you know your system running information which sometime you need to find them out.
Microsoft Windows 7 Correct, but there is an even newer one in the pipeline - they don't fire their design/program engineers, you know.
as we all know when computer is booted first it search the operating system like Windows, linux etc to the Hard disk and then with the help of the operating system computer start his works and when a process or program is to be started by the user, it first go to the RAM and operating system takes the process from RAM and then doing his own further work. RAM is a storage for temporarily process that is read by the operating system and when computer shut down then all processes and programs which are in RAM, automatically deleted. Through the various types of processes operating system works from different types of processes.
Which/whose DOS? The earliest DOS that I know of was one of two very primitive operating systems developed by IBM in 1964-1965 for the System/360 because their planned operating system (which never did get finished to specification) was hopelessly behind schedule and overbudget. These were TOS (Tape Operating System) and DOS (Disk Operating System), both were simple batch job operating systems with only primitive multitasking ability (to prevent the computer from being idle when a program did I/O.).
None, as far as I know, possibly MS-DOS, I know FreeNAS can be run from a 32MB, but it's a server Operating system.
Considering an operating system running applications such as webrowsers and mail programs will be a security threat to the computer system, as we all know, information, files and database coming from the internet or the outer source of the computer is an unauthorized to the operating system because of some of the absences of the author, who wrote it? Where did it came from? The OS has no clue about that, and it will result for the intrusion of the unwanted programs in the system which can damage file on the computer, it can be a reason why OS don't have applications already installed to the system up until now. It's up to the user whether he will install web browsers and mailprograms in the system manually without the OS commanding on it.
