OPERATING SYSTEMS

LINUX:

Linux is a Unix-like operating system that was designed to provide personal computer users a free or very low-cost operating system comparable to more expensive UNIX systems. Linux has an identity as a very efficient and fast-performing system. It is best of free and open source software development and distribution.

 Linux is publicly open and can be extended by contributors. Because it conforms to the Portable Operating System Interface standard user and programming interfaces, developers can write programs that can be transferred to other operating systems. Linux has expanded to become a force in computing.  Android and Ubuntu are some of the Linux based operating systems.

Advantages of Linux:

Low cost: Spending time and money to obtain license is not required since Linux and much of its software come with the GNU General Public License. Additionally, there are large repositories from which you can freely download high quality software for almost any task you want.

Stability: Linux does not need to be rebooted periodically to maintain performance levels as it doesn’t freeze up or slow down over time due to memory leaks.

Performance: It provides continuous high performance on workstations and on networks.

Network friendliness: Linux being developed by a group of programmers over the Internet has therefore strong support for network functionality. The client and server systems can be easily set up on any computer running Linux.

Flexibility: It can be used for high performance server applications, desktop applications, and embedded systems.

Compatibility: It runs all common Unix Software packages and can process all common file formats.

Choice: Linux distributions gives choice to pick the one we like best of the large numbers of distributions.

Fast and Easy installation: Most of them come with user-friendly installation and setup programs.

Full use of hard disk: Linux continues work well even when the hard disk is almost full.

Multitasking: Linux is designed to do many things at the same time; e.g., a large printing job in the background won’t slow down you other work.

Security:  Linux is one of the most secure operating systems. “Walls” and flexible file access permission systems prevent access by viruses.

Open Source: If you develop software that requires knowledge or modification of the operating system code, Linux’s source code is at your fingertips.

OPENINDIANA:

Open Indiana is a Unix-like computer operating system. It was released as free and open source software. It forked from Open Solaris after the discontinuation of that project by Oracle and aims to continue development and distribution of the Open Solaris codebase.

ANDROID:

Android is a Linux-based operating system for mobile devices like cell phones and tablet form computers. It has a large group of developers who write applications that increase the functionality of the devices.

The platform of android is adjusting to larger 2D graphics & 3D graphics library based on OpenGLES specifications and traditional Smartphone layouts. It is a lightweight used for data storage purpose. It supports connectivity with GSM, CDMA, and Wi-Fi etc. SMS and MMS are its available form of messaging. It supports multiple languages. It’s totally Java supported. It also supports many audio/video/still media formats.

Android has native support for multi-touch which was initially made available in handsets. It supports Bluetooth. Android does not support native video calling, but some handsets have a customized version of the operating system that supports it, either via the UMTS network (like the Samsung Galaxy S) or over IP. It avails multitasking of applications. It also supports wireless use of phones.

Advantages of ANDROID:

Open Nature: Basically it is designed for smart phones but its open and changeable nature of operating system allows it to be used on laptops, net books, smart books etc.

Android is also intended to be used by Google to televisions with Google TV. Also it can be seen on wristwatches, smart glasses, refrigerators head phones.

It provides easy benefits for mobile application developers. Also it is easy to handle and implement.

It’s because of Android that application developers are coming to fore and offering services at extremely affordable rates.

HAIKU:

Haiku is a free and open source operating system. It is compatible and inspired with Be Operating System. Its main goal is to become a fast, simple to use, easy to learn, efficient and then to a powerful system for computer users.

Development of haiku is by a raising community of volunteer developers from all over the world. Haiku is the realization of those concepts and technologies that represent the ideal means to simple and efficient personal computing in the form of an OS that is open source and free.

Advantages of HAIKU:

It has a specific focus on personal computing.

It has a custom kernel for responsiveness.

It comes with fully threaded design for great efficiency with multi-processor/core CPUs.

It has rich OO API [Application Programming Interface] for faster development.

It composes Database-like file system [BFS] with support for indexed metadata.

It has a Unified & cohesive interface.

FREE BSD:

FreeBSD is a free Unix-like operating system bought out from

AT&T UNIX via BSD UNIX. BSD has its root in UNIX. These OS

are most commonly found on web servers, although they can also

function as personal computers OS.
 

Advantages of Free BSD:

Networking: It is greatly contributed by implementation of 4.2BSD based on TCP/IP stack. It also supports AppleTalk, IPX, SCTP, and IPv6.

Storage: FreeBSD has Soft update that maintains files system integrity in event of system crash.

Security: It provides features like access control lists, security event auditing, extended file attributes, fine grained capabilities and mandatory access controls.

Portability: Its project manages architectures into tiers like Tier 1 are mature and fully supported, Tier 2 undergoing major development, Tier 3 are no longer under active development and Tier 4 have no support at all.

 

Mac OS X:

Mac OS X is an Open core graphical operating system produced by Apple Inc. Mac OS X server is identical by design to its desktop part but runs on Apple’s line of Macintosh server hardware. Its server involves administration software tool and work group management that provides simplified access to main network services. It includes mail transfer agent, a samba server, LDAP server, a domain name server and others.
 

Advantages of Mac OS X:

It provides best security in its terms and much less likely to get infected.

It takes up less system resources.

It has a simple, easy-to-use interface that is perfect for kids, technophobic etc. also its easy for the home user and enough powerful for the programmers.

All programs work flawlessly and not visible together thereby creating a snap from e-mailing to home movie DVD.

Mac computers last longer for years than normal computers.

Mac runs many games like World of War craft; Star craft, War craft III etc.

 

Google Chrome OS:

Google Chrome OS is a Linux-based operating system. It is designed to work more with web applications. It stays on specific hardware from Google’s manufacturing partners. The intention of its design was having user documents and files stored on online servers.
It includes an integrated file manager same as those found on another OS with function of allowing user to playback MP3, see JPEGs etc while offline.
 

Advantages of Google Chrome OS:

It is a light weight, cloud based OS hence complex programs are not able to run.

It is open source software. No cost involved.

It allows maximum online stay continuously.

It is designed in such a manner that it is faster than any other OS.

This OS will automatically update the security system by default.

Google services like Gmail, Google docs., Picasa etc all will be inbuilt and will also have offline access.

Any web based application can run in Chrome OS.
