(3) The system software sends hardware instructions to the computer hardware;

(4) The computer hardware performs processing and sends the results to the system software;

(5) The system software sends a service response to the application program; and

(6) The application program produces program output for the user.

Communication between the user and the application program is the only kind of input and output available to users. Application programs, on the other hand, communicate with the system software in order to make requests for fundamental services (e.g. opening a file, reading data from a file, etc.). The system software takes a service request and converts it into a series of machine instructions before sending those instructions to the hardware to be carried out. The system software then gets the results of the hardware executing out those instructions.

12) Question:

What exactly is system software?

Answer:

System software is the first thing most of us see when we turn on a new personal computer, as it is pre-installed on the hard disc.

18) Question:

To clarify, what do the terms "software-platform" and "cross-platform" mean?

Answer:

There are a variety of available operating systems. Operating systems are often categorized by computer size. As an example, a mainframe computer and a desktop computer use different operating systems. It's not uncommon for machines of the same general kind (desktops, for example) to run on different operating systems. Not only that, but in many cases these different Operating systems are incompatible with one another. Furthermore, application software designed for one operating system may not function properly when used with another. The “software platform” can refer to the computer's OS or to any other piece of software that runs on the computer. The application software we buy always specifies which computer system it must run on. An application that is "cross-platform" will function in exactly the same way across different platforms.

19) Question:

Can you describe the function of operating systems?

Answer:

Regardless of the hardware specifications, an operating system's primary responsibilities are the same across the board. These include:

(1) Booting the computer;

(2) Displaying a user interface;

(3) Controlling which programs is run;

(4) Allocating memory;

(5) Coordinating tasks;

(6) Setting up the device's configuration;

(7) Connecting to the internet;

(8) Keeping a close watch on the system's performance; and

(9) Providing tools for managing files.

Booting the computer:

Booting is the process of powering on or restarting a computer. A computer is "cold booted" when it is turned on after being totally turned off. Restarting a computer that is already on is called a "warm boot." A warm boot will appropriately terminate all running applications and processes. Unsaved changes are not preserved in any way. Consequently, before restarting our computer, we must constantly save our work.

Displaying a user interface:

Developing a friendly interface for users is essential for any piece of software. The user interface (UI) is the part of software with which the user interacts, determining the ways by which input data and instructions are processed and displayed visually. Whenever we interact with a computer, we do it by way of the operating system's user interface. User interfaces can be either (i) Command-line,

(ii) Menu driven, or

(iii) Graphical.

Controlling which programs is run:

Depending on how the operating system is supposed to be used, it can support just one user running one program or thousands of users running multiple programs at the same time. The different things that operating systems can do are called single tasking, multiple users, multiple tasks, multiple processors, and virtual memory. One operating system may support some or all of these features, which has a direct effect on how productive users are.

(i) Single User/Single Tasking: A single user/single tasking operating system only lets one user run one program at a time. For example, if we are working in a graphics program and want to check our e-mail, we must quit the graphics program before we can run the e-mail program. Early systems were only good for one user and one task. Smart phones and other personal mobile devices often use operating systems that only work for one user and one task at a time.

(ii) Single User/Multitasking: Most operating systems today can handle more than one task at a time. A single-user, multitasking operating system lets a single user work on two or more programs that are in memory at the same time. Using the above example, if we are using a single-user, multitasking operating system, we don't have to stop the graphics program to run the e-mail program. Both programs can run at the same time.

(iii) Multi-User: With a multi-user operating system, two or more people can run programs at the same time. Networks, mainframes, and supercomputers are multi-user because they can be used by hundreds or thousands of people at the same time.

(iv) Multiprocessing: An operating system that supports multiprocessing let two or more processors run programs at the same time. Multiprocessing is when more than one processor works on the same program at the same time. This makes the computer work faster.

Allocating memory:

Memory management's goal is to make the most efficient use of RAM possible. An operating system will ‘allocate’ or ‘assign’ data and instructions to a portion of memory in order to store them there until they may be executed. The contents of memory are then closely tracked. When the operating system determines that the items being tracked in memory are no longer needed by the CPU, it frees up that space.

Coordinating tasks:

The order in which tasks are done is set by the operating system. A job or task is an activity that the processor takes care of. Tasks include:

(i) Getting information from an input device;

(ii) Processing instructions;

(iii) Sending information to an output device; and

(iv) Moving things from storage to memory and from memory to storage.

A computer can do tens of thousands of things at the same time. The scheduling in different parts of the computer is handled by the operating system. This makes it possible to work on different parts of different tasks at the same time.

A buffer is an area of memory or storage where data and information are kept while they are waiting to be sent to or from an input or output device. It controls devices like printers that take in information and send it out. When jobs are sent to the printer, the operating system often uses buffers.

Setting up the device's configuration:

The operating system depends on device drivers in order to communicate to each hardware component of the computer. A device driver is a little piece of software that takes instructions from another program and translates them into language the device can understand. A computer requires a separate driver for each peripheral connected to it, including the keyboard, mouse, monitor, printer, card reader/writer, and scanner. At system startup, the OS retrieves the necessary drivers for all of the computer's hardware. Without the proper device driver being installed on the computer, these accessories will not work.

Connecting to the internet:

Connecting to the Internet is commonly a feature built into operating systems. Some operating systems also come with a web browser and an email client, so we can start using the Internet and corresponding with people as soon as we establish an online connection..

Keeping a close watch on the system's performance:

The operating system keeps an eye on how well the computer is doing. Everything that happens on the computer is recorded. This tool provides reports on the status of different hardware and software components in the system, including the CPU, physical memory, and network. It logs every user activity and program usage on the system. A performance monitor is a common component of operating systems. A performance monitor is a piece of software that checks the status of your computer's hardware and resources and then provides you with detailed reports.
