In 1991, while studying computer science at University of Helsinki, Linus Torvalds began a project that later became the Linux kernel.
He wrote the program specifically for the hardware he was using and independent of an operating system because he wanted to use the functions of his new PC with an 80386 processor.Unix.
Unix (/ˈjuːnɪks/; trademarked as UNIX) is a family of multitasking, multiuser computer operating systems that derive from the original AT&T Unix, development starting in the 1970s at the Bell Labs research center by Ken Thompson, Dennis Ritchie, and others.Android version history

What came first Linux or Windows?
Windows 1.0 was released in 1985 , Linux kernel was first released in 1991 . The first distro appeared in 1992 . It’s worth mentioning that UNIX appeared way before any of these, in 1971 . The first BSD in 1978 .
What was there before Windows?
PCs Before Windows: What Using MS-DOS Was Actually Like. Consumer PCs didn’t always run Windows. Before Windows arrived, PCs came with Microsoft’s MS-DOS operating system. Here’s what the command-line environment was actually like to use.
What is the history of operating system?
The first operating system was introduced in the early 1950’s, it was called GMOS and was created by General Motors for IBM’s machine the 701. Operating systems in the 1950’s were called single-stream batch processing systems because the data was submitted in groups.
What is the name of world’s first time sharing operating system?
CTSS used a modified IBM 7090 mainframe computer that had two 32,768 (32K) 36-bit-word banks of core memory instead of the normal one.
Which is the oldest OS?
Microsoft’s first operating system, MDOS/MIDAS, was designed along many of the PDP-11 features, but for microprocessor based systems. MS-DOS, or PC DOS when supplied by IBM, was based originally on CP/M-80. Each of these machines had a small boot program in ROM which loaded the OS itself from disk.
Why is Linux better than Windows?
Linux is much more stable than Windows, it can run for 10 years without the need of a single Reboot. Linux is open source and completely Free. Linux is much more secure than Windows OS, Windows malwares doesn’t effect Linux and Viruses are very less for linux in comparison with Windows.
Who created operating system?
On August 28, 1980, Microsoft signed an agreement with IBM to develop software for the PC. Gates was aware of an operating system called QDOS, which had been developed by a fellow Seattle resident named Tim Paterson.
Will there be a Windows 11?
Windows 12 is all about VR. Our sources from the company confirmed that Microsoft is planning to release a new operating system called Windows 12 in early 2019. Indeed, there will be no Windows 11, as the company decided to jump straight to Windows 12.
What did MS DOS do?
MS-DOS is a computer operating system by Microsoft Corporation. It stands for “Microsoft Disk Operating System”, and came from an operating system Microsoft bought called QDOS, or the “Quick and Dirty Operating System.” The operating system used a command-line interface for the user to input commands.
What is time sharing operating system with example?
In other words, time sharing refers to the allocation of computer resources in time slots to several programs simultaneously. For example a mainframe computer that has many users logged on to it. Each user uses the resources of the mainframe -i.e. memory, CPU etc.
What is operating system generation?
First Generation: Vacuum Tubes (1940-1956) The first computer systems used vacuum tubes for circuitry and magnetic drums for memory, and were often enormous, taking up entire rooms.
What is mainframe technology?
Mainframe computers or mainframes (colloquially referred to as “big iron”) are computers used primarily by large organizations for critical applications; bulk data processing, such as census, industry and consumer statistics, enterprise resource planning; and transaction processing.
Is Linux older than Windows?
Technically Windows as an OS itself did not come out until 1993, however Windows *did* exist as an MS-DOS shell way back in 1985…long before Linux. Also, Windows 1.0 is seen as the first official Windows on the market. Linux first came out first as an actual OS in 1991.
Which operating system began as a programmer’s operating system?
The first operating system was created by General Motors in 1956 to run a single IBM mainframe computer. Other IBM mainframe owners followed suit and created their own operating systems.
What operating system was before Windows 10?

- Windows Server 2008.
- Windows Server 2000.
- Windows 8.
- Windows Server 2003.

Why I should use Linux?
Linux makes very efficient use of the system’s resources. Linux runs on a range of hardware, right from supercomputers to watches. You can give new life to your old and slow Windows system by installing a lightweight Linux system, or even run a NAS or media streamer using a particular distribution of Linux.
What are the advantages of Linux over Windows?
The advantage over operating systems such as Windows is that security flaws are caught before they become an issue for the public. Because Linux does not dominate the market like Windows, there are some disadvantages to using the operating system. First, it’s more difficult to find applications to support your needs.
How much did Bill Gates pay for DOS?
Gates actually sent IBM to Kildall to buy/license a version of CP/M for the new IBM personal computer. When IBM couldn’t or wouldn’t make a deal with Kildall, Microsoft bought what became MS DOS from Seattle Computer Products for $50,000 and licensed it to IBM.
What is the purpose of MS DOS?
The first Microsoft Windows operating system was really an application that ran on top of the MS-DOS operating system. Today, Windows operating systems continue to support DOS (or a DOS-like user interface) for special purposes by emulating the operating system.
Is MS Word an operating system?
So, is Microsoft Word an operating system? Microsoft Word is not an operating system, but rather a word processor. This software application runs on both the Microsoft Windows operating system as well as the Apple Macintosh operating system.
What is mainframe architecture?
Mainframe architecture is the design of mainframe computers used for large-scale computing applications, such as data storage or customer statistics, as well as processing other types of bulk information.
Is mainframe a server?
Mainframes are typically built by IBM and usually run z/OS. A server (when referred to in the hardware sense) is a PC with higher reliability / quality parts and runs usually a *NIX variant, or Windows Server. Mainframes can run software services, such as JEE application servers, web servers, etc.
Why is Mainframe still used?
New mainframe hardware and software products are ideal for Web transactions because they are designed to allow huge numbers of users and applications to rapidly and simultaneously access the same data without interfering with each other. Perform large-scale transaction processing (thousands of transactions per second)
