3 Popular Open Source Operating Systems

An Operating System remains the soul of any computer. We have seen many over time, but the one that has stood out strong is Microsoft Widows. Windows occupies around 90 % of the total operating system market. And why shouldn’t it?  Windows is easy-to-use and comes equipped with all the services one would expect from any OS – and is considered to be better than open source operating system. But there are always some, who may be looking out for a free operating system for their computers.

Today I will list down 3 of the post popular, open-source, and therefore free, operating systems available to computer users. Speaking about the open source world, there are some quite impressive operating systems - that can be useful at times. Earlier I had talked about 5 open source database - and today I will discuss 3 open source operating systems and their features, in brief.

Ubuntu

The most widely used open source data base is Ubuntu. It is a Linux based operating system and is distributed free along with the source code. Its desktop looks somewhat similar to that of Windows, with window controls and icons. There is reasonable large software support available on Ubuntu; the common applications include Mozilla Firefox web browser, LibreOffice office application suite, GIMP image editor and so on.

Ubuntu is distributed under GNU and GPL license. It has UNIX shell called as Terminal that can be used to interact with the network and install third-party applications.

Ubuntu Features, Specifications and Requirements

  • Support for ARM and x86 boards1
  • Local storage support for DVR functionality2
  • Minimum disk space: 2GB
  • Minimum memory: 512 MB
  • HDMI
  • CEC support
  • Secure full-featured web
  • Social networking services
  • Gallery

One of the interesting feature on Ubuntu is, integration of broadcast, online services and applications. This gives you real TV experience on desktop since you can now get media on demand.

Ubuntu needs very little effort for installation. You can download the Windows Installer here.

FreeBSD

FreeBSD is an advanced operating system for x86 compatible (including Pentium and Athlon), AMD64 compatible. It is popular among network developers, as FreeBSD offers advanced networking, performance, security and compatibility features. Most software that runs on Linux can run on FreeBSD without the need for any compatibility layer. FreeBSD nonetheless still provides a compatibility layer for several other Unix-like operating systems, including Linux. As a result, most Linux binaries can be run on FreeBSD.

FreeBSD is available under open source and can be installed from a variety of media including CD-ROM, DVD, or directly over the network using FTP or NFS.

FreeBSD Features

1) FreeBSD ships with advance hardware specifications that now supports advance file systems called as ZFS file system (highly scalable multiprocessing performance.)

2) SMPng: The SMPng architecture allows concurrency in the kernel. This makes OS perform fast as it can scale to over 8 CPU cores for many workloads.

3) Wireless:  enhances wireless support, including high-power Atheros-based cards, new drivers for Ralink, Intel, and ZyDAS cards, WPA, background scanning and roaming, and 802.11n.

FreeBSD also includes support for encryption software, secure shells, Kerberos authentication, “virtual servers”.

You can download FreeBSD here.

OpenSolaris

OpenSolaris is a computer operating system developed by Sun Microsystems. It runs well on desktops, laptops, servers and data centers. OpenSolaris is GUI based like Ubuntu and has rich graphical desktop and windows for easy navigation. It is now available in version 11 and can be downloaded without any cost from the Oracle website.

OpenSolaris Features

  • ZFS (the file system)
  • bootable clones
  • checksums on data
  • storage pools (zpools)
  • snapshots (utilizing copy-on-write)
  • Timeslider

In addition, Sun’s ZFS file system now has native solid-state drive (SSD) management technology, meant to allow system administrators to fine-tune SSD performance.

    “The most widely used open source data base is Ubuntu.” ???
    this must be an error ?
    otherwise it´s good info.
    but you should also mention the other “ubuntu-versions”: Xubuntu, Kubuntu.
    Another linux-distribution (version) worth mentioning is Debian which together with the Ubuntu-versions is considered to be the most stable and reliable Linux-distributions.

    Ubuntu is a nice user-friendly robust operating system that’s perfect for non-geeks and geeks alike. I really liked using Ubuntu.

  • Khan Azharuddin12345

    Oh Yes Hackerman1. That was an error. And Yes will discuss Xubuntu and Kubuntu in a separate post..

  • Ayman Abdelazim
