Android is an Operating System for mobiles that runs on Linux Kernel. It was developed by Android Inc. but was later purchased buy GOOGLE.
Some of the features of ANDROID OS are as following:
WEB BROWSER - LibWebCore - a modern web browser engine which powers both the Android browser and an embeddable web view.
Storage: - SQLite - a powerful and lightweight relational database engine available to all applications.
Media support: - Android supports : MPEG-4 SP, AMR, AMR-WB (in 3GP container), AAC, HE-AAC (in MP4 or 3GP container), MP3, MIDI, OGG Vorbis, WAV, JPEG, PNG, GIF, BMP
Additional Hardware Support: Android can use video/still cameras, touchscreens, GPS, accelerometers, magnetometers, accelerated 2D bit blits (with hardware orientation, scaling, pixel format conversion) and accelerated 3D graphics.
Multi-touch: Android has native support for multi-touch which is available in newer handsets such as the HTC Hero. The feature was initially disabled at the kernel level (possibly to avoid infringing Apple patents on touch-screen technology
Connectivity: Android supports connectivity technologies including GSM/EDGE, CDMA, EV-DO, UMTS, Bluetooth, and Wi-Fi.
USES and ADVANTAGES:
As it's a mobile Operating System its extensively used in cell phones, ipods etc.
The application used by this OS are mostly built by GOOGLE Inc. having better efficiency and reliability.
A new phone (NEXUS ONE) has been officially announced by GOOGLE which has everything you can do with computer. Though its not available in PAKISTAN yet.
About Future Extension of ANDROID:
Google is still working on it. And upcoming with better applications of it. Google is making things easier in the field of computer science as well as in the field of Telecommunication as it can be seen by the launch of new phone NEXUS ONE having ANDROID Operating System.
Debian GNU/Linux is a free operating system, developed by more than a thousand volunteers from all over the world who collaborate via the Internet. Debian's dedication to Free Software, its non-profit nature, and its open development model make it unique among GNU/Linux distributions.
Debian GNU/Linux runs on computers ranging from palmtops and handheld systems to supercomputers, and on nearly everything in between. A total of twelve architectures are supported: Sun SPARC (sparc), HP Alpha (alpha), Motorola/IBM PowerPC (powerpc), Intel IA-32 (i386), IA-64 (ia64), HP PA-RISC (hppa), MIPS (mips, mipsel), ARM (arm, armel), IBM S/390 (s390), and AMD64 and Intel EM64T (amd64).
FEATURES OF DEBIAN:
- Many of the Operating System are based on DEBIAN like Ubuntu, MEPIS, Dreamlinux, Damn Small Linux, Xandros, Knoppix, BackTrack, Linspire, sidux, Kanotix, Parsix and LinEx.
- You can run Debian on anything. If you're a developer you can get Linux to run on any system under the sun. For example you can get Linux to run on an iPhone or a Microsoft xBox 360. But, if you're not a programmer and you want to run Linux on a Sun SPARC server, an HP Alpha server, an IBM s/390 mainframe on the big iron side to a lightweight ARM Cortex-powered netbook or a Marvell Orion-powered HP Media Vault mv2120 storage device, Debian will run on it. This is pretty darn handy whether you're upgrading your servers or just want one common interface across your entire office's computer collection.
- Debian is now Java friendly. The Linux distribution now includes Sun's OpenJDK; the GNU Java compiler and Java bytecode interpreter; and Classpath, an open-source collection of Java libraries. What all this means for users is that you can now use most Java-based programs in Debian. Some of these are already available in Debian's software repositories, so you can quickly use these programs.
- Renewed emphasis on security. In the not-to-distant past, Debian put its foot into it with a major OpenSSL security screw-up. Unlike some groups, say Microsoft, which never seems to learn security lessons, Debian's developers worked hard to improve the distribution's security.
A Debian GNU system is upgraded to a new minor subrelease or to a new major release by using one out of many methods. Single desktop machines can use the CD-ROM-method or the network-method while the machine runs without the need to reboot it.
Debian packages integrate very well into the entire system. Several tools and gadgets are used to help connecting packages to each other, presenting the user a well maintained and round system.
For all packages of the distribution the whole source is available. The entire distribution is free according to the DFSG which also means that everybody can improve packages and still distribute them.
- User Support
Debian does not have an office in any country providing first- and second-level support. This is an advantage since pretty much any problem is likely to be answered within a few hours by other expert Debian users or Debian developers on one of the mailing lists.
- Remote Maintenance:
openSUSE, is a general purpose operating system built on top of the Linux kernel, developed by the community-supported openSUSE Project and sponsored by Novell. After acquiring SUSE Linux in January 2004, Novell decided to release the SUSE Linux Professional product as a 100% open source project, involving the community in the development process.
- Gnome 2.24.1
openSUSE 11.1 comes with GNOME 2.24, which was released last month. That includes a handful of nice improvements, such as an improved support for tabbed file browsing. OpenSUSE's GNOME environment ships with a great assortment of default applications. One particularly pleasing addition to beta 3, for instance, is Tasque-a to-do list utility that can integrate with the likes of Milk web service.
- Open Office ORG 3.0 (OOo)
The OpenOffice.org (OOo) project ranks high among the most popular open source software applications. The cross-platform productivity suite has been developed to its newer version of 3.0 and all set to release with openSUSE in the next month.
- Mono 2.0.1
Mono 2.0 is a portable and open source implementation of the .NET framework. Mono 2.0.1 works on the bugs and fixes them accordingly. Some of the major features include
- Extensive support for databases: PostgreSQL, DB2, Oracle, Sybase, SQL server, SQLite and Firebird.
- C5 Generics Library: we are bundling the C5 generics collection class library as part of Mono.
- Compatibility with C# 3.0
- Has improved support for Windows.Forms such as ADO.NET, ASP.NET, SYSTEM.XML etc.
- Finger Print Reader
Finger Print Readers are more sensitive and accurate in openSUSE 11.1. Only one fingerprint per user can be registered. The user's fingerprint data is stored to /etc/pam_thinkfinger/login.bir. We will have to see how it works actually.
- Software Upgrades
With the likes of Firefox 3.0.3 and Banshee 1.3.3 (don't know yet if it is the exact version) which has iPod upgradation in-built, the software package will be nothing less than attractive for normal users.
- Crashes are very rare even in kde. Many kde distros exists which crashes often taking away the interest of users from linux.
- Huge Repositories, including third party repositories. There is hardly any tool which you will not find.
- Large community support.
- Large wiki-base which helps in finding solutions of the problems more quickly.
About WINDOWS 7:
Windows 7 is an Operating System on personal computers, including home and business desktops, laptops, notebooks, tablet PCs, and media center PCs. Windows 7 was intended to be a more focused, incremental upgrade to the Windows line, with the goal of being fully compatible with applications and hardware with which Windows Vista is already compatible
Misconception: (That its more and more a VISTA):
Windows 7 is not quite a "Vista service pack." It does share a lot of the core tech, and was clearly designed to fix nearly every bad thing anyone said about Vista. Which ironically puts the demon that it was trying to exorcise at its heart? What that means is that Windows 7 is what Vista should have been in the public eye-a solid OS with plenty of modern eye candy that mostly succeeds in taking Windows usability into the 21st century-but it doesn't daringly innovate or push boundaries or smash down walls or whatever verb meets solid object metaphor you want to use, because it had a specific set of obligations to meet, courtesy of its forebear.
GOOGLE CHROME OS (upcoming)
Google Chrome OS is an open source operating system designed by Google to work exclusively with web applications. Announced on July 7, 2009, Chrome OS is set to have a publicly available stable release during the second half of 2010. The operating system is based on Linux and will run only on specifically designed hardware
ADVANTAGES AND EXPECTED FEATURES OF GOOGLE CHROME OS:
- Speedy boot-up, as fast as three-seconds:
A Chrome OS device will not store any applications on the device itself. Nada, none, zippo, says Pichai. Likewise, it will include only the hardware, right down to the component level, that Google has approved in its hardware reference specification. The only applications it will use are those that can be run from the cloud in a browser, the Chrome browser, to be specific
- Security by default:
The portion of the operating system needed to operate the device will reside in a read-only section of memory. The rest of the operating system is integrated with the Chrome browser and, like the browser, security updates require nothing more than a reboot. Chrome OS can run multiple Web applications in multiple tabs and each one is locked down from all others, so a vulnerability in one Web app can't lead to exposure in another. User data stored on the device, which is minimal, is encrypted.
- Support for both x86 and ARM architectures:
Google promises that it will be writing native code for both popular netbook CPUs.
Some more Features:
- Open Source
- Light Weight
- Virus Free
