What is the operating system? How many types of operating system?

What is the operating system? The operating system is one of the most important “parts” of the computer. Almost all types of computers need an operating system to function properly, including mobile telephones, video games, e-book readers, and DVRs. When one turns on the computer, the operating system tells how the processor, memory, disk space, etc. will work.

What is the operating system?

The operating system is the software that manages every part of the computer system – all the hardware and all the other software. It controls every file, every device, every section of main memory, every nanosecond of processing and every network connection. It also determines who can use the system and how to control it. In short, operating system is the boss, nothing can happen without it.

When a computer user sends commands by typing from the keyboard or clicking with the mouse, the operating system verifies whether the command has been executed. If this does not work, the operating system must usually send a message to the user on the monitor explaining the error.

How many types of operating system and what?

Most simple, single-function computers (such as microwave ovens with digital keypads) do not require an operating system. In fact, trying to implement an operating system on these computers would be foolish. On the other hand, all personal desktop and laptop computers and servers require an operating system. While there are hundreds of operating systems, the most popular by far are the Microsoft Windows family of operating systems, the Macintosh operating system, and the Unix family.

What is Unix operating system?

Unix is a multi-user, multitasking operating system like Linux and was designed as a small, flexible system used by computer programmers. Unix is not considered very user-friendly for everyone due to its design. However, graphical user interfaces have been developed for Unix to help alleviate this ease-of-use problem.

What is the Linux operating system?

Linux is an operating system that has been widely adopted in commercial and academic markets around the world. Linux is unique among the most widely used operating systems in that it is an open-source program, meaning that the source code can be used by anyone for improvement.

Programmers around the world are encouraged to submit improvements to the programming code. If the new code is recognized as an operating system public improvement, it is added to the next version, which is made available to the computing world for further improvements. This has resulted in a powerful, stable, cheap operating system, which is constantly being improved by different people.

Linux was created in Finland by 21-year-old Linus Torvalds who wanted to create a new operating system for the Intel 80386 microprocessor. Torvalds started with Minix, a miniature version of the well-known UNIX operating system, and rewrote parts to add more functionality. The first version of Linux, named for Torvalds and UNIX, had the core functionality of the Unix-like power and flexibility of the popular MS-DOS operating system at the time. It has increased substantially since 1991.

Although the two systems have similarities, Linux is not Unix. (UNIX is a legal trademark, registered with the federal government.

What is Windows operating system?

The most popular and widely known operating system is Windows, an operating system introduced in 1985 by Microsoft Corporation. Windows employs a graphical user interface (GUI), which eliminates the need for the user to learn complex commands. What is Windows operating system? With a GUI, the user instructs the operating system by using the mouse to point and click on icons displayed on the screen. The first version of Windows, released in November 1985, was designed as a GUI add-on for MS-DOS (Microsoft Disk Operating System), Microsoft's original command-line operating system.

To communicate with computers, DOS users had to type commands or instructions at a command prompt, and then the command-line interpreter executed those commands. DOS has limited use with modern computer systems and applications because it does not support multiple users or multitasking. It is not as “user friendly” as GUI operating systems. In the late 1990s, most command-line operating systems were replaced by user-friendly systems using GUIs.

After the release of Windows 3.1 in 1991, Windows experienced a significant increase in market share, and since the mid-1990s Microsoft has dominated the operating-system market. Microsoft released Windows 99 in August 1995. It was so well marketed and in such high demand that people bought the operating system even if they didn't have a home computer. Microsoft has gained popularity with each new release from Windows 98 to Windows 2000 to Windows XP to Windows Vista. By 2004, Microsoft commanded nearly 90 percent of the operating system market. The latest Windows release, Windows Vista, was launched in January 2000, five years after the introduction of Windows XP's predecessor, the longest time between Windows releases. While Vista is only slowly gaining popularity, Windows XP remains the world's dominant operating system with a 79 percent market share in September 2007 (compared to 7 percent for Vista).

What is the Mac operating system?

The second most popular family of operating systems is Mac OS. What is Mac Operating System? Macintosh is often credited with introducing GUI-style operating systems; Mac OS was not the first graphical user interface but the first successful one, mainly because the competitors were so expensive – the Xerox Alto, the first true GUI system.

Mac OS cost $32,000 to produce, while Macintoshes cost $2,500. It became more popular then other GUI computers due to its relative affordability. The first Mac OS, unnamed at the time but now known as “System 1,” was launched in 1984. It had a desktop, windows, icons, a mouse, menus and scrollbars.

Early versions of Mac OS could only be used on Apple computers. In 1991, Apple introduced computers with PowerPC hardware. These computers can run either Windows or Mac OS. The latest version of Mac OS, OS X, was first introduced in 2000. Can be used on computers with both PowerPC and Intel processors, allowing for a wider range of applications and uses. But Mac OS is far behind Microsoft Windows. In 2007, it was the third most popular operating system in the world, behind Windows XP and Windows Vista — but accounted for less than three percent of the operating-system market.

What is the Android operating system?

Google didn't make the Android OS. Actually, Android is made by Android Inc. in Palo Alto, California. was created by The company was founded in October 2003 by Andy Rubin, Rich Miner, Nick Sears and Chris White. What is the Android operating system? They were originally intended to develop an operating system for digital cameras. However, when they realized that the market for digital cameras was not large enough, they switched to a smartphone operating system to compete with Symbian and Windows Mobile when the Apple iPhone was not yet released. In the same year, Andy Rubin ran out of money, so on August 17, 2005, Google Android Inc. achieved Since then Android has been rapidly growing and developing its mobile device platform.

What is iOS operating system?

IOS (iPhone OS) is a mobile operating system developed by Apple Inc. Developed by and exclusively for its hardware, it is the operating system that currently powers many of the company's mobile devices, including the iPhone and iPod touch. Before the introduction of ipadOS in 2012, it ran with this operating system. It is the second most popular mobile operating system worldwide after Android.
