Firefox OS



Firefox OS (project name: Boot to Gecko, also known as B2G) is a Linux-based open-source operating system for smartphones and tablet computers. It is being developed by Mozilla, the non-profit organization best known for the Firefox web browser.

Firefox OS is designed to provide a "complete" community-based alternative system for mobile devices, using open standards and approaches such as HTML5 applications, JavaScript, a robust privilege model, open web APIs to communicate directly with cellphone hardware, and application marketplace. As such, it competes with proprietary systems such as Apple's iOS, Google's Chrome OS and Microsoft's Windows Phone, as well as other open source systems such as Android, Jolla's Sailfish OS and Ubuntu Touch.


Firefox OS was publicly demonstrated in February 2012, on Android-compatible smartphones, and again in 2013 running on Raspberry Pi. In January 2013, at CES 2013, ZTE confirmed they would be shipping a smartphone with Firefox OS, and on July 2, 2013, Telefónica launched the first commercial Firefox OS based phone, ZTE Open, in Spain which was quickly followed by GeeksPhone's Peak+.

Computer Virus


Computer viruses are small software programs that are designed to spread from one computer to another and to interfere with computer operation.

Through the course of using the Internet and your computer, you may have come in to contact with computer viruses. Many computer viruses are stopped before they can start, but there is still an ever growing concern as to what do computer viruses do and the list of common computer virus symptoms. A computer virus might corrupt or delete data on your computer, use your email program to spread itself to other computers, or even erase everything on your hard disk.

Computer viruses are often spread by attachments in email messages or instant messaging messages. That is why it is essential that you never open email attachments unless you know who it's from and you are expecting it.
Viruses can be disguised as attachments of funny images, greeting cards, or audio and video files.

Computer viruses also spread through downloads on the Internet. They can be hidden in illicit software or other files or programs you might download.

To help avoid computer viruses, it's essential that you keep your computer current with the latest updates and antivirus tools, stay informed about recent threats, run your computer as a standard user (not as administrator), and that you follow a few basic ruleswhen you surf the Internet, download files, and open attachments.

Once a virus is on your computer, its type or the method it used to get there is not as important as removing it and preventing further infection.

Android

    Android is an operating system for mobile devices such as cellular phones, tablet computers and netbooks. Android was developed by Google and based upon the Linux kernel and GNU software. It was initially developed by Android Inc. (a firm later purchased by Google) and lately by the Open Handset Alliance. According to NPD Group, unit sales for Android OS smartphones ranked second among all smartphone OS handsets sold in the U.S. in the first quarter of 2010. BlackBerry OS holds 36% and iOS holds 21% ranked first and third respectively with Android at second with 28%. A Nielsen report for the same quarter placed Android in fourth place with 9% of the market.

    Android has a large community of developers writing apps that extend the functionality of the devices. There are currently over 70,000 apps available for Android, which makes it the second most popular mobile development target. Developers write managed code in the Java language, controlling the device via Google-developed Java libraries.

    The unveiling of the Android distribution on 5 November 2007 was announced with the founding of the Open Handset Alliance, a consortium of 71 hardware, software, and telecom companies devoted to advancing open standards for mobile devices. Google released most of the Android code under the Apache License, a free software and open source license.

    The Android operating system software stack consists of Java applications running on a Java based object oriented application framework on top of Java core libraries running on a Dalvik virtual machine featuring JIT compilation. Libraries written in C include the surface manager, OpenCore[1] media framework, SQLite relational database management system, OpenGL ES 2.0 3D graphics API, WebKit layout engine, SGL graphics engine, SSL, and Bionic libc. The Android operating system consists of 12 million lines of code including 3 million lines of XML, 2.8 million lines of C, 2.1 million lines of Java, and 1.75 million lines of C++.
