What is an operating system?

An operating system (OS) is the Application Which, after being initially loaded into the computer by a boot program, oversees all the other application programs in a computer. The application programs make use of the working system by making Furthermore, users can interact directly with the operating system Via a user interface like a command line or a graphical user interface (GUI).

Types of operating systems.

Operating systems normally include pre-loaded on almost any Computer you purchase. Many men and women use the operating system which comes with their computer, however it is possible to update or perhaps alter operating systems. The three most frequent operating systems for personal computers are Microsoft Windows, macOS, and Linux. A GUI enables you to use your mouse to click on icons, switches , and menus, and that which is clearly displayed on the display by means of a combo of images and text. Each operating system's GUI includes a different feel and look, so if you Switch to another operating system it might appear unfamiliar at first. However, modern operating systems have been made to be effortless to utilize , and the majority of the fundamental principles are exactly the same.

Microsoft established the Windows operating platform at the mid-1980s. There have been a number of distinct variants of Windows, but the latest ones are Windows 10 (published in 2015), Windows 8 (2012), Windows 7 (2009), along with Windows Vista (2007). Windows includes pre-loaded on many new PCs, which helps to ensure it is the hottest operating system on the planet.

MacOS (formerly called OS X) is a Lineup of operating systems made by Apple. It comes preloaded on all Macintosh computers, or Macs. A number of the specific models include Mojave (published in 2018), High Sierra (2017), and Sierra (2016). Based on StatCounter Global Stats, macOS users accounts for significantly less than 10 percent of international functioning systems--considerably lower than the percent of Windows users (greater than 80 percent ). 1 reason behind this is that Apple computers have a tendency to be costlier. But a lot of individuals do prefer the appearance and feel of macOS over Windows.

Linux (pronounced LINN-ux) is a household of open-source operating systems, so they may be altered and distributed by all around the globe. This differs from proprietary program such as Windows, which may only be altered by the organization that owns it. The benefits of Linux are that it's free, and there are several different distributions or variations you may select from. Based on StatCounter Global Stats, Linux users accounts for under 2 percent of international functioning systems. But most servers run Linux since it's relatively simple to personalize.

The operating systems we have been speaking about so much were created to operate on desktop and notebook computers. Mobile apparatus like telephones , tablets , and MP3 players Are distinct from desktop and notebook computers, so that they run operating systems that have been designed especially for mobile devices. From the screenshot below, you can view iOS running in an iPad. Operating systems for mobile devices normally are not as fully featured As those created for desktop and notebook computers, and they are not capable to Run each the exact same software. But, you can still perform a Great Deal of things Together, like watch videos, browse the net, manage your calendarand play games.

Ubuntu Blog: Productivity is but a snap away – useful applications for your everyday needs

The state of being productive comes in various guises. Sometimes, you want to do more. Sometimes, you want less. It’s been a while since we toured the Snap Store, and we thought you would be interested in a fresh batch of cool, fun and useful applications that can help you perfect your daily digital activities. Without further ado, let’s have a look.

Auto-cpufreq

Thanks to thermodynamics, power and performance are two opposing forces. Not a problem when you have unlimited power – wall plugs – but on laptops draining precious limited battery charge, every electron counts. It is not without reason that performance optimisation is an important art with battery-powered devices.

Auto-cpufreq is a small utility that lets you profile your current power utilisation and recommend suggestions, designed to find the right balance between energy drain and speed so that you get both responsiveness and longevity on your system. This app can monitor CPU frequencies and temperatures, your battery state and system load, and then make recommendations on the optimal CPU frequency scaling, governor and turbo boost management. The changes can be applied temporarily – and once you’re happy –...

Onefetch – one fetch to rule them all

If you’d like to know the details of your software project (sources) at a glance, you can. Onefetch is a command-line tool that can inspect Git-based project directories, and provide elegant summaries. This includes the breakdown of commits by authors, repo creation and change information, composition of languages, licensing information, lines of code, commits, and a few other details. Some 50 programming languages are supported.

QR Code Generator

There is no shortage of QR code generators available online. But sometimes, you may want to generate links that you don’t necessarily want publicised. In such scenarios, offline tools can come in handy, and the QR Generator snap does exactly that. It allows you to create PNG images containing QR-coded information (links or any arbitrary text). You can specify the image size in pixels, as well as write down large amounts of text.

Restic

Backups are important. Very important. So much in fact that we’ve dedicated several articles to this topic, including how to backup application settings and how to create snapshots of your snaps. Having a reliable, robust and well-tested backup infrastructure in place can provide insurance for when (not if) your hardware fails.

Restic is a snapshot-based backup program, designed to be relatively simple to use, secure and efficient. Indeed, at first glance, Restic can look overwhelming, but it has an intuitive workflow. You start by creating an encrypted backup repository – it can be local or remote. Once the repository is ready, you can start creating backups. Snapshots are incremental, which can help save space and time needed to copy your files. Then, when you want or need to restore the data, you can list your snapshots, select the relevant timestamp, and restore the information to a target directory. It does not have to be the original location, so you can inspect and verify the contents.

restic init --repo ~/backups
enter password for new repository:
enter password again:
created restic repository 8a74242390 at /home/igor/backups
restic backup ~/Documents -r ~/backups
restic snapshots -r ~/backups
enter password for repository:
repository 8a742423 opened successfully, password is correct

Bulk URL Opener

If you’re using session management extensions in your browsers, you will be familiar with the concept. But then, you may have information on websites saved in multiple locations – bookmarks, text files, incompatible browser add-ons, and you would like to keep all the links in one tidy location. Bulk URL Opener could be the solution to that need.

The utility allows you to save and load any number of URL lists, with websites saved one entry per line. You can also customize how the application behaves; for instance, when you open a large list, you may want to introduce a delay in between the loading of different tabs in order to reduce the load on your default browser and the network.

Communitheme – Yaru for Ubuntu 18.04 LTS

The Ubuntu distribution has undergone a major visual change going from Ubuntu 18.04 to Ubuntu 18.10. A new theme – Yaru – was introduced, bringing in a fresh palette of purple and dark grey. If you want to try this look on Ubuntu 18.04 – you can, without having to resort to any manual work of getting the right themes, icons and other assets. The communitheme snap provides all the elements needed to transform Bionic.

Once the snap is installed, you will have a new login session option available. Once you select your name, click on the cogwheel and select Ubuntu with communitheme snap. Once you’re logged in, you will have the new Yaru window border decorations and icons available.

Summary

We hope you enjoyed today’s tour. There’s something for everyone – developers, people who seek improved battery life on their laptops, smartphone users, those looking for a robust backup setup, and Ubuntu 18.04 users with a penchant for eye candy. If you’d like to suggest unique software that can help people gain more fun and efficiency in their day-to-day computing, or perhaps talk about this article, please join our forum for a discussion.
