The Linux operating system is a great alternative to Windows One important point to note about Linux is that there are many different versions, or distributions as they’re known. Each version is based around a kernel (the core part of the operating system), but they vary when it comes to the interface and software they include. Ubuntu is one of the most popular and easy-to-use distributions you can try any other distribution if you prefer; Linux Mint, Mandriva, Debian, Fedora and Qimo are all popular choices. linux really will cost you nothing. Not only is the operating system itself free, but all the software and utilities you’ll need are either included as part of Linux or you can install them with just a few clicks, all for free. For another thing here are another reasons why you should switch to using the Ubuntu operating system.
Introduction of linux
Linux is a Unix-like operating system. The main difference compared to conventional Unix systems is that Linux together with the complete source code may be freely copied. An operating system is a bundle of programs that implement the most basic functions of a computer: the interface between people and machine (specifically: the management of keyboard, screen, etc.) and the management of system resources (CPU time, memory etc.). You need one Operating system so that you can start an application program of your own Can save data in a file. Popular operating systems are Windows, Linux, BSD, OS X and iOS. Unix existed long before Windows, Linux or OS X. This operating system was equipped from the start with features that Microsoft had only very much were later offered in a comparable form: real multitasking, one Separation of processes from each other, clearly defined access rights for files, mature Network functions etc.
However, Unix initially only offered a nicely user interface and high hardware requirements. This explains, why Unix almost exclusively on expensive workstations in the scientific and industrial area was used. Unix is used in this book as a generic term for various of the original Unix derived operating systems used. The names of these operating systems end usually on -ix (Irix, Xenix etc.) and are mostly protected trademarks of respective companies. UNIX itself is also a protected trademark. Linux is a version of Unix, but the source code is freely available. Big parts of the Internet (e.g. Google) are carried by Linux. The programs you have to buy for Windows are free in Linux. It can be incredibly frustrating when you get your new PC home, set it up and go to load Microsoft Word.
free software of linux
You’ll either find that you have a trial version that can be run 25 times, or that it isn’t installed at all. You won’t have that problem with Ubuntu. The LibreOffice suite is installed by default, and has compatible versions of Word, Excel, PowerPoint and Outlook. That means you can create letters, presentations and spreadsheets and start sending and receiving emails immediately. There’s plenty else besides: photo-editing software, music and video players, instant messaging and disc-burning utilities – the list goes on and on. Ubuntu will run on just about any computer. Whether you have the latest quad-core PC or a relic with hardly any RAM, Ubuntu will work. In fact, it will use the full power of both those machines, so whatever you have it isn’t wasted by running Ubuntu on it. Because Ubuntu is a very lightweight operating system, older computers can be given a new lease of life.
Instead of feeling sluggish and taking 10 minutes to boot up, they can feel snappy simply by swapping a clogged-up version of Windows with Ubuntu. Viruses and malware are virtually nonissues. Because most computers run Windows, the vast majority of viruses are written to target that operating system. There are almost no cases of Linux suffering from virus attacks, and as Ubuntu is updated regularly, potential security holes are patched very quickly. Extra reassurance comes from the fact that, unlike Windows, the main computer user doesn’t have administrator rights. In simple terms, this means there’s a limit to the parts of the operating system that can be accessed, and this provides greater safety from malware.
Updates are easy.
Ubuntu has a central update manager that manages updates for all the programs you’ve installed. This means there’s just one place you need to go to get new versions, and one program to run. Windows, on the other hand, doesn’t manage updates for third-party software. A typical Windows PC is littered with programs that run constantly, checking to see if a new version of the program is available. This uses up system resources and makes your computer run more slowly.
You don’t need a second monitor.
In Windows, you have only one desktop. Open more than a few windows and you’ll soon become tired of juggling them all. In Ubuntu, you have multiple workspaces, which are like virtual monitors. Click on an icon, and you switch to a new, clean desktop. It’s so easy to flip between workspaces that you’ll never be able to go back.
There’s no shareware, adware or serial numbers. If you want to install extra programs, you do it through Ubuntu’s Package Manager. There are thousands of applications to choose from, and all are free. If you like the software, you keep using it. If not, you simply uninstall it. You’ll never have to enter your details, nor will you be bombarded by emails.
It’s just like Windows.
If you know how to use Windows, you’ll be right at home with Ubuntu. Almost everything works the same way, from the ‘start’ menu to navigating through files and folders. Tool tips will pop up to help you learn what each icon and button does, and there’s also a comprehensive Help Center.
Hardware support is much better than it used to be. One reason many people haven’t tried Linux is because they think it won’t work with their hardware. The truth is that, unless you have a really obscure bit of kit, Ubuntu is likely to work with it. You’ll probably find that most of your computer’s features work as soon as Ubuntu is installed, from wireless networking to your memory card reader.
