System software is the software used to run and maintain the pc these are essential to the pc and without it the pc would not function

A computers operating system (OS) is the core of the computer and is more than just software. The OS controls the computer’s memory and processes as well as its hardware and software. It is the brain of the computer. Software applications on the other hand perform a certain task. Ex. Google Chrome provides internet and Adobe allows PDF files to be read (among other things). The OS is what makes all of these applications work successfully and accomplish whatever the application is designed to accomplish.

Operating systems are vital to the use of computers, they tell the machine what it is, what language, where the programs are, when things are stored, how to do things, the instruction codes to do everything. The system is in charge of security such as ensuring that unauthorised users do not access the system. There are many types of operating systems, a few are listed below:

Drugs have the ability to alter the transmission of a neuron that causes a person to change their state of being. These drugs may have some medical uses that may treat diseases or elevate moods, however there are some drugs that are used recreationally that also elevate moods but do not offer any medical usage. For other living beings, they are used for self-defense against other predators and these chemicals that inject can also alter the state of mind and even death.

Operating systems have the responsibility to ensure that users do not access the system illegally. They also perform different tasks such as managing system resources, communicate between software and hardware, monitoring performance and operate utilities and applications.

The operating system is the set of instructions that direct the computer to accomplish specific tasks such as document production and spreadsheet calculations.

Operating systems and application software are essential in the running of computers. The operating system is the most important piece of software on a computer. It controls the computers software/hardware, memory and processing. It also allows the user to control the computer without knowing its operating language. An example of an operating system is Mac OS X. Application software is often designed for a specific purpose such as word processing, Web browsers or spreadsheets etc. These applications can often be used to do other jobs than just the one intended. For example you could use word to edit photos but this is not the applications intended use, so it will not have advanced image-editing features which a program like Photoshop would

An operating system is a vital component of the computer system. The common and simple devices like refrigerators and microwave ovens does not have an operating system. The complex systems which handle several components, functions and processes usually have an operating system. The operating system is like the brain of a human being, the brain is an essential organ in the body of human being which sends signals and helps functioning of the human body. Our intelligence, attitude, emotions and senses defines our presence, all these are possible because of our brain. In similar manner, “Operating System” (OS) is the power behind a computer system. In other words, operating system is brain of the computer and processor is the heart of the computer. A computer is the concatenation of several hardware parts. The operating system manages computer hardware resources and provides common services for computer programs and other application software.

The operating system whatever it may be (Windows or Linux) it is the most important program that runs on a computer. All general purpose computers require an operating system in order to run other programs. The Operating system performs essential basic tasks such as recognizing input from the keyboard, keeping track of files and their directories on the disk, the sending output to the display screen and the controlling of peripheral devices such as keyboards and printers.

Process management creates processes, and implements multitasking by switching the active process on the processor.

An operating system is an interface between a user and the hardware of a computer. It is just a set of software that manages computer hardware and controls the operations on the computer. Operating system is the base of the application programs because they cannot contact the hardware directly. It does not do any work itself, it just provides an environment in which the other programs on a computer can run. Therefore, when a user enters or sends a command the operating system makes sure that the command is executed or not, if not it displays a message explaining the error. Without operating system a computer is of no use it is just a metal block.

An Operating System is the software that manages the sharing of the resources, processes system data and user input, and responds by allocating and managing tasks and internal system resources as a service to users and programs of the system (UzEE, 2007).

In computing, booting is the initialization of a computerized system. The system can be a computer or a computer appliance. The booting process can be "hard", after electrical power to the CPU is switched from off to on (in order to diagnose particular hardware errors), or "soft", when those power-on self-tests (POST) can be avoided. Soft booting can be initiated by hardware such as a button press, or by software command. Booting is complete when the normal, operative, runtime environment is attained.

The function of a operating system gives commands to the hardware and also tells how much resources to use from the hardware to complete the needed tasks. The OS manages all the connected hardware in your PC such as hard drives, a mouse, keyboard, displays a cursor on the screen which allows you to navigate threw the system much easier.

An operating system (OS) is a software program that enables the computer hardware to communicate and operate with the computer software. OS is the software that supports a computer 's basic functions, such as scheduling tasks, executing applications, and controlling peripherals. It is a program that acts as an interface between the user and the computer hardware and controls the execution of all kinds of programs in computer/computer devices. The users of the computer interact with the system and application software which are installed and function in OS. Likewise for the hardware such as Keyboard, printers, mouse, CPU, registers, disks, monitors, RAM and other I/O devices to be functional they need an operating system in which their systems are embedded (fig. 1 shows the interaction)
