8 Effective Operating System Elevator Pitches
What is an operating system?

An operating system serves as a bridge between a computer's user and its hardware. An operating system's function is to offer a setting in which a user can conveniently and effectively run programmes.
In order to guarantee the proper operation of the computer system and prevent user programmes from interfering with that operation, the hardware must offer the necessary mechanisms.
History Of OS
An interface between the computer system and the user is provided by the operating system, a system programme. Operating systems establish a comfortable and well-organized environment in which the user can utilise any programmes and interact with any software or apps.
Additionally, an operating system is a piece of software that governs and regulates how computer hardware, software resources, and application applications are used. Input/output, memory, input/output, and various peripheral devices like a disc drive, printers, etc. are just a few of the software and hardware resources it aids in managing. The widely used operating systems include Linux OS, Windows OS, Mac OS, VMS, OS/400, and others.
Functions of operating system

1. File Management
The management of files on a computer is the responsibility of the operating system. File creation, opening, shutting, and deletion all fall under this category. The disk's files are organised by the operating system as well.
Consider your computer to be a dwelling. The OS would serve as the home's property manager, in charge of supervising daily activities and making sure everything is in working order. This entails controlling who has access to them and what files and folders are stored on the computer.
The OS also controls file permissions, which specify what operations a user is permitted to perform on a given file or folder. You might be able to read a file but not edit or remove it, for instance. As a result, nobody else is able to access or alter your data.
2. Device management
Essential features for controlling devices linked to a computer are provided by operating systems. These processes include managing storage devices, processing input and output requests, and allocating memory. A keyboard, mouse, printer, or any other connected device could be this one.
You will have options through an operating system to control how each gadget acts. You could, for instance, configure your keyboard so that you can only text in a certain language or limit the mouse movement to one screen at a time.
An operating system can also be used to control security settings and install software and updates for your devices.
3. Process management
The management of the processes that are active on your computer is the job of the operating system. Program initiation and terminating, resource distribution, and memory management all fall under this category.
The operating system makes ensuring that all of the software your computer runs is compatible. Additionally, it is in charge of enforcing software security, which aids in protecting your computer from potential threats.
Each process is allotted a quantum of time to complete its work. The operating system stops a process when it has used its quantum and gives another process a chance. This guarantees that each process receives an equal amount of CPU time.
4. Memory management
Memory management is one of an operating system's most important features. This is the procedure for monitoring all of the many programmes and applications that are active on your computer, together with the data they are consuming.
This is crucial for computers with less memory since it prevents any programme or process from using too much memory and bogging down your machine. To free up space, the operating system might move data around and remove files.
The operating system loads itself into memory during computer startup and subsequently controls all other running processes. It assesses how much memory is being utilised and how much is free, and it ensures that running programmes do not conflict with one another.
5. Job Accounting
The task accounting feature of an operating system (OS) is an effective tool for monitoring how your computer's resources are being used. You can use this information to locate and resolve any performance problems as well as spot any unwanted programme installations.
The users and processes that consume the most resources are recorded by operating systems. This data can be used for a number of things, such as monitoring system usage, charging users for resource use, and informing system administrators about which users and processes are problematic.
Advantages of Operating System
Computing Source: OS serves as a conduit between the hardware and the user. Users are able to access the output, process operations, and input data, among other activities. Users can interact with computers to carry out many tasks, including mathematical calculations, with the aid of an operating system.
User-Friendly Interface: The introduction of the Graphical User Interface (GUI) for the Windows operating system made it more user-friendly. Additionally, it makes it easier for users to comprehend, work with, and connect with computers.
Resource Sharing: Resource sharing is possible on operating systems. Printers, modems, and fax machines are used to share data and information with other users. We may communicate information and data via email with the aid of networks, and an operating system allows us to transfer diverse apps, photos, and media files from a PC to other devices.
No Coding Lines: Since the advent of the GUI, operating systems are now able to access hardware without the need for programme writing.
Safeguard of Data: On the computers, we may store more data, and by using the operating system, we can access that data. The data is being managed by OS in a secure and safe manner.
Software Update: An operating system must be updated in order to keep up with the demands of its users in daily life; this is done simply by updating its software.
Multitasking: An operating system is capable of managing multiple tasks at once.
Disadvantages of Operating System
1.Expensive: Some operating systems are more expensive than others, like Linux. Users can use a free operating system, but they are typically a little more challenging to operate than others. The cost of the Microsoft Windows operating system with its GUI and other built-in features is high.
2.System Failure: If the main operating system fails, the entire system will be affected and the machine will not function. We are aware that the operating system is the brains of a computer system, without which the system cannot run. There will be no more data processing if the central system fails, which will stop all connectivity.
3.Highly Complex: Operating systems are incredibly complex, and the language that was used to create them isn't really specified or clear.
4.Virus Threats: Because operating systems are vulnerable to such virus attacks, they are under greater threat. Many users install harmful software packages on their computers, which slows down and stops the OS from operating.
5.Fragmentation: When storage memory fragments, the computer is said to be in a fragmented state. When the manner of operation exceeds the capacity of the memory, internal fragmentation results. When a technique or process is abandoned, external fragmentation results.
