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.

Review: The New weLees Visual LVM, a new style of LVM management, has been released

weLees Visual LVM Manager
by George Whittaker

Maintenance of the storage system is a daily job for system administrators. Linux provides users with a wealth of storage capabilities, and powerful built-in maintenance tools. However, these tools are hardly friendly to system administrators while generally considerable effort is required for mastery.

As a Linux built-in storage model, LVM provides users with plenty flexible management modes to fit various needs. For users who can fully utilize its functions, LVM could meet almost all needs. But the premise is thorough understanding of the LVM model, dozens of commands as well as accompanying parameters.

The graphical interface would dramatically simplify both learning curve and operation with LVM, in a similar approach as partition tools that are widely used on Windows/Linux platforms. Although scripts with commands are suitable for daily, automatic tasks, the script could not handle all functions in LVM. For instance, manual calculation and processing are still required by many tasks.

Maintenance of the storage system is a daily job for system administrators. Linux provides users with a wealth of storage capabilities, and powerful built-in maintenance tools.

The graphical interface would dramatically simplify both learning curve and operation with LVM, in a similar approach as partition tools that are widely used on Windows/Linux platforms. Although scripts with commands are suitable for daily, automatic tasks, the script could not handle all functions in LVM. For instance, manual calculation and processing are still required by many tasks.

Significant effort had been spent on this problem. Nowadays, several graphical LVM management tools are already available on the Internet, some of them are built-in with Linux distributions and others are developed by third parties. But there remains a critical problem: desire for remote machines or headless servers are completely ignored.

This is now solved by Visual LVM Remote. Front end of this tool is developed based on the HTTP protocol. With any smart device that can connect to the storage server, Users can perform management operations.

Visual LVM is developed by weLees Corporation and supports all Linux distributions. In addition to working with remote/headless servers, it also supports more advanced features of LVM compared with various on-shelf graphic LVM management tools.

Dependences of Visual LVM Remote

Visual LVM Remote can work on any Linux distribution that including two components below:

  • LVM2

  • Libstdc++.so

UI of Visual LVM Remote

With a concise UI, partitions/physical volumes/logical volumes are displayed by disk layout. With a glance, disk/volume group information can be obtained immediately. In addition, detailed relevant information of the object will be displayed in the information bar below with the mouse hover on the concerned object.
