The operating system is the central nervous system of the computer, it controls fan speed to cool down your devices, it controls the settings for your computer, it moves the mouse cursor on the screen when you move the mouse. The operating system does everything you do. The video card is only as useful as the system hardware, but what controls the hardware? The operating system.
The operating system controls lots of things. Some specific tasks include: control access to memory; control the running of programs; control access to the hard disk; control user access; provide many useful functions that can be used by other programs. Take your pick.
Three main tasks that an OS performs are:
resource management
hardware abstraction
user interface
hardware, software, scanning and printing
The operating system.
The software that helps a computer perform essential operating tasks and enables other software to run is the operating system.
Devices that record precise results require a real-time operating system. This is the same kind of operating system needed for a device hat performs regimented tasks.
To describe a collection of computer programs, procedures, and documentation that perform some tasks on an operating system.
The instructions in these files inform the various components of the computer system about such tasks as recognition of components, communications, data processing, internal data transfer, and memory management.
The operating system allows you to use the computer, but you need specific programs to perform specific tasks. There is no single piece of software that allows you to perform every specific task.
System software is a collection of programs and data that helps the computer carry out its basic operating tasks.
Software is a general term used to describe a collection of computer programs, procedures and documentation that perform some tasks on an operating system. In Simple words you can say software is the way to perform different tasks electronically.
It's true. The operating system is the main set of instructions the computer needs to enable it to work. Without the operating system, the other programs couldn't interact or perform their tasks.
A server is basically a PC, but with a different operating system that allows it to perform server tasks. To change it to a PC, or a PC to a server, you only need to install the operating system corresponding to the tasks you want it to perform. If you put a partition on your hard drive you can even install both operating systems, and use the same computer as either a server or a PC depending on your needs
In centralised tasks are done by one system and in distributed tasks are shared by the many computers
first the booting files are loaded in the RAM and these files are in the boot sector where operating system is installed . after loading these file then these files load the operating system in the RAM , some portion of RAM is Allocated by the OS. after that window is ready to perform tasks.
