WINDOWS OPERATING SYSTEM:-
Windows is a popular operating system developed by Microsoft Corporation. It is designed to provide a user-friendly interface for personal computers and other computing devices. Windows OS provides a graphical user interface (GUI) that allows users to interact with the computer using icons, menus, and other visual elements.
The first version of Windows was released in 1985, and since then, Microsoft has released many versions, including Windows 95, Windows XP, Windows 7, Windows 8, Windows 10, and the latest version as of my knowledge cutoff in 2021 was Windows 11.
Windows is designed to run on a wide range of hardware, from desktops and laptops to tablets and smartphones. It supports a wide range of software applications and devices, making it a popular choice for personal and professional use. Windows also offers a range of built-in features, including a web browser, media player, and productivity tools like Word, Excel, and PowerPoint.
FUNCTIONS:-
Functions are a fundamental concept in computer programming, used to group a set of instructions together to perform a specific task or computation. A function is a reusable block of code that can be called from other parts of a program, allowing for modular and organized code.
In most programming languages, a function is defined with a name and a set of input parameters, which are variables or values passed into the function. The function then performs a specific set of instructions using the input parameters and possibly some local variables, and produces a result or output that is returned to the calling code.
Functions can be used to perform a wide range of tasks, from simple calculations and data manipulation to complex algorithms and data processing. They are often used to simplify code and reduce redundancy, by allowing common tasks to be performed with a single function call.
In addition to user-defined functions, most programming languages also include built-in functions that provide useful functionality, such as math functions, string manipulation functions, and input/output functions. These built-in functions can be called from any part of the program without needing to be defined or implemented by the programmer.
