Cloud computing is an expression used to describe a variety of computing concepts that involve a large number of computers connected through a real-time communication network such as the Internet. In science, cloud computing is a synonym for distributed computing over a network, and means the ability to run a program or application on many connected computers at the same time. The phrase also more commonly refers to network-based services, which appear to be provided by real server hardware, and are in fact served up by virtual hardware, simulated by software running on one or more real machines. Such virtual servers do not physically exist and can therefore be moved around and scaled up (or down) on the fly without affecting the end user - arguably, rather like a cloud.
The popularity of the term can be attributed to its use in marketing to sell hosted services in the sense of application service provisioning that run client server software on a remote location.
A portable application (portable app), sometimes also called standalone, is a program designed to run on a compatible computer without being installed in a way that modifies the computer's configuration information. This type of application can be stored on any storage device, including internal mass storage and external storage such as USB drives and floppy disks – storing its program files and any configuration information and data on the storage medium alone. If no configuration information is required a portable program can be run from read-only storage such as CD-ROMs and DVD-ROMs. Some applications are available in both installable and portable versions.
Like any application, portable applications must be compatible with the computer system hardware and operating system.
A computer virus is a type of malware that, when executed, replicates by inserting copies of itself (possibly modified) into other computer programs, data files, or the boot sector of the hard drive; when this replication succeeds, the affected areas are then said to be "infected". Viruses often perform some type of harmful activity on infected hosts, such as stealing hard disk space or CPU time, accessing private information, corrupting data, displaying political or humorous messages on the user's screen, spamming their contacts, or logging their keystrokes. However, not all viruses carry a destructive payload or attempt to hide themselves—the defining characteristic of viruses is that they are self-replicating computer programs which install themselves without the user's consent.
Virus writers use social engineering and exploit detailed knowledge of security vulnerabilities to gain access to their hosts' computing resources. The vast majority of viruses (over 99%) target systems running Microsoft Windows, employing a variety of mechanisms to infect new hosts, and often using complex anti-detection/stealth strategies to evade antivirus software. Motives for creating viruses can include seeking profit, desire to send a political message, personal amusement, to demonstrate that a vulnerability exists in software, for sabotage and denial of service, or simply because they wish to explore artificial life and evolutionary algorithms.
Google Chrome OS is a Linux-based operating system designed by Google to work primarily with web applications. The user interface takes a minimalist approach and consists almost entirely of just the Google Chrome web browser; since the operating system is aimed at users who spend most of their computer time on the Web, the only "native" applications on Chrome OS are a browser, media player and file manager. This means that Chrome OS is almost a pure web thin client OS.
Chrome OS is built upon the open source project called Chromium OS which, unlike Chrome OS, can be compiled from the downloaded source code. Chrome OS is the commercial version installed on specific hardware from Google's manufacturing partners. The launch date for retail hardware featuring Chrome OS was delayed from late 2010 to June 15, 2011, when "Chromebooks" from Samsung, and then Acer in July, shipped.
The Chrome Web Store is Google's online store for web applications for Google Chrome or Google Apps. It was announced at the Google I/O conference on May 19, 2010 by Vic Gundotra and released on December 6, 2010. The software allows users to install and run web applications for the Google Chrome browser. The Chrome Web Store user experience and design was created by Fi.
The Internet is a global system of interconnected computer networks that use the standard Internet protocol suite (TCP/IP) to serve several billion users worldwide. It is a network of networks that consists of millions of private, public, academic, business, and government networks, of local to global scope, that are linked by a broad array of electronic, wireless and optical networking technologies. The Internet carries an extensive range of information resources and services, such as the inter-linked hypertext documents of the World Wide Web (WWW), the infrastructure to support email, and peer-to-peer networks.
Most traditional communications media including telephone, music, film, and television are being reshaped or redefined by the Internet, giving birth to new services such as voice over Internet Protocol (VoIP) and Internet Protocol television (IPTV). Newspaper, book and other print publishing are adapting to website technology, or are reshaped into blogging and web feeds. The Internet has enabled and accelerated new forms of human interactions through instant messaging, Internet forums, and social networking. Online shopping has boomed both for major retail outlets and small artisans and traders. Business-to-business and financial services on the Internet affect supply chains across entire industries.
