Features Of The Opera Web Browser
This article details features of the Opera web browser. Currently supported features ;Access recently closed pages: Opera allows its users to retrieve all of the tabs or windows closed earlier in the current session from a list. Closed tabs can be recovered in the reverse sequence in which they were closed, by default this is achieved via the keyboard shortcut Ctrl + Shift + T. Users can also access recently closed tabs from other devices synced to their Opera account, including tablets and phones. Opera 7, released 28 January 2003 ;Download manager: Opera allows its users to pause, resume, or restart the transfer of files. It also keeps the history of downloaded files and allows opening the files—or the folder where the file has been downloaded to—from within the browser. When a download begins, a pop-up and a button will appear at the top-right area of the interface to show the download progress. ;Extensions: Extensions allow users to easily add functionality to their O ...

Opera (web Browser)
Opera is a multi-platform web browser developed by its namesake company Opera. The browser is based on Chromium, but distinguishes itself from other Chromium-based browsers ( Chrome, Edge, etc.) through its user interface and other features. Opera was initially released on 10 April 1995, making it one of the oldest desktop web browsers still actively developed. It was commercial software for its first ten years and had its own proprietary layout engine, Presto. In 2013, it switched from the Presto engine to Chromium. Opera is available on Windows, macOS, Linux, Android, and iOS (Safari WebKit engine). There are also mobile versions called Opera Mobile and Opera Mini. Opera users also have access to Opera News, a news app based on an AI platform. The company released a gaming-oriented version of the browser, Opera GX, in 2019, and a blockchain-focused Opera Crypto Browser into public beta in January 2022. History In 1994, Jon Stephenson von Tetzchner and Geir Ivarsøy st ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Opera 2015 Icon
Opera is a form of theatre in which music is a fundamental component and dramatic roles are taken by singers. Such a "work" (the literal translation of the Italian word "opera") is typically a collaboration between a composer and a librettist and incorporates a number of the performing arts, such as acting, scenery, costume, and sometimes dance or ballet. The performance is typically given in an opera house, accompanied by an orchestra or smaller musical ensemble, which since the early 19th century has been led by a conductor. Although musical theatre is closely related to opera, the two are considered to be distinct from one another. Opera is a key part of the Western classical music tradition. Originally understood as an entirely sung piece, in contrast to a play with songs, opera has come to include numerous genres, including some that include spoken dialogue such as ''Singspiel'' and ''Opéra comique''. In traditional number opera, singers employ two styles of singing ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Java (software Platform)
Java is a set of computer software and specifications developed by James Gosling at Sun Microsystems, which was later acquired by the Oracle Corporation, that provides a system for developing application software and deploying it in a cross-platform computing environment. Java is used in a wide variety of computing platforms from embedded devices and mobile phones to enterprise servers and supercomputers. Java applets, which are less common than standalone Java applications, were commonly run in secure, sandboxed environments to provide many features of native applications through being embedded in HTML pages. Writing in the Java programming language is the primary way to produce code that will be deployed as byte code in a Java virtual machine (JVM); byte code compilers are also available for other languages, including Ada, JavaScript, Python, and Ruby. In addition, several languages have been designed to run natively on the JVM, including Clojure, Groovy, and Scala. J ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Image
An image is a visual representation of something. It can be two-dimensional, three-dimensional, or somehow otherwise feed into the visual system to convey information. An image can be an artifact, such as a photograph or other two-dimensional picture, that resembles a subject. In the context of signal processing, an image is a distributed amplitude of color(s). In optics, the term “image” may refer specifically to a 2D image. An image does not have to use the entire visual system to be a visual representation. A popular example of this is of a greyscale image, which uses the visual system's sensitivity to brightness across all wavelengths, without taking into account different colors. A black and white visual representation of something is still an image, even though it does not make full use of the visual system's capabilities. Images are typically still, but in some cases can be moving or animated. Characteristics Images may be two or three-dimensional, such as a ph ...

Page Zooming
In computing, page zooming is the ability to zoom in and out a document or image at page level. It is usually found in applications related to document layout and publishing, e.g. word processing and spreadsheet programs, but it can also be found in web browsers as it improves accessibility for people with visual impairment and people using mobile devices, such as PDAs and mobiles which have a relatively small screen. Different modes There are two notably different modes of page zooming: * ''text resizing'' that resizes the text by increasing or decreasing the font size, with wrapping to avoid horizontal scrolling, leaving the size of the images the same. * real ''page zooming'' mode that resizes also images, other multimedia objects, and viewports. When zooming in, a horizontal scroll bar will appear when the screen is not wide enough to hold the page content. Early web browsers had only the ability to resize the text on a page, but in the meantime all major browsers have the a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Opera Mini
Opera Mini is a mobile web browser made by Opera. It was primarily designed for the Java ME platform, as a low-end sibling for Opera Mobile, but it is now developed exclusively for Android. It was previously developed for iOS, Windows 10 Mobile, Windows Phone 8.1, BlackBerry, Symbian, and Bada. As of 2022, the Android build is the only version still under active development. Opera Mini was derived from the Opera web browser. Opera Mini requests web pages through Opera Software's compression proxy server. The compression server processes and compresses requested web pages before sending them to the mobile phone. The compression ratio is 90% and the transfer speed is increased by two to three times as a result. The pre-processing increases compatibility with web pages not designed for mobile phones. However, interactive sites which depend upon the device processing JavaScript do not work properly. In July 2012, Opera Software reported that Opera Mini had 168.8 million users as o ...

Data Transmission
Data transmission and data reception or, more broadly, data communication or digital communications is the transfer and reception of data in the form of a digital bitstream or a digitized analog signal transmitted over a point-to-point or point-to-multipoint communication channel. Examples of such channels are copper wires, optical fibers, wireless communication using radio spectrum, storage media and computer buses. The data are represented as an electromagnetic signal, such as an electrical voltage, radiowave, microwave, or infrared signal. Analog transmission is a method of conveying voice, data, image, signal or video information using a continuous signal which varies in amplitude, phase, or some other property in proportion to that of a variable. The messages are either represented by a sequence of pulses by means of a line code (''baseband transmission''), or by a limited set of continuously varying waveforms (''passband transmission''), using a digital modulat ...

Internet
The Internet (or internet) is the global system of interconnected computer networks that uses the Internet protocol suite (TCP/IP) to communicate between networks and devices. It is a '' network of networks'' that consists of private, public, academic, business, and government networks of local to global scope, linked by a broad array of electronic, wireless, and optical networking technologies. The Internet carries a vast range of information resources and services, such as the inter-linked hypertext documents and applications of the World Wide Web (WWW), electronic mail, telephony, and file sharing. The origins of the Internet date back to the development of packet switching and research commissioned by the United States Department of Defense in the 1960s to enable time-sharing of computers. The primary precursor network, the ARPANET, initially served as a backbone for interconnection of regional academic and military networks in the 1970s to enable resource shari ...

HTTPS
Hypertext Transfer Protocol Secure (HTTPS) is an extension of the Hypertext Transfer Protocol (HTTP). It is used for secure communication over a computer network, and is widely used on the Internet. In HTTPS, the communication protocol is encrypted using Transport Layer Security (TLS) or, formerly, Secure Sockets Layer (SSL). The protocol is therefore also referred to as HTTP over TLS, or HTTP over SSL. The principal motivations for HTTPS are authentication of the accessed website, and protection of the privacy and integrity of the exchanged data while in transit. It protects against man-in-the-middle attacks, and the bidirectional encryption of communications between a client and server protects the communications against eavesdropping and tampering. The authentication aspect of HTTPS requires a trusted third party to sign server-side digital certificates. This was historically an expensive operation, which meant fully authenticated HTTPS connections were usually found only ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Memory Compression
Virtual memory compression (also referred to as RAM compression and memory compression) is a memory management technique that utilizes data compression to reduce the size or number of paging requests to and from the auxiliary storage. In a virtual memory compression system, pages to be paged out of virtual memory are compressed and stored in physical memory, which is usually random-access memory (RAM), or sent as compressed to auxiliary storage such as a hard disk drive (HDD) or solid-state drive (SSD). In both cases the virtual memory range, whose contents has been compressed, is marked inaccessible so that attempts to access compressed pages can trigger page faults and reversal of the process (retrieval from auxiliary storage and decompression). The footprint of the data being paged is reduced by the compression process; in the first instance, the freed RAM is returned to the available physical memory pool, while the compressed portion is kept in RAM. In the second instance, the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Opera 5
The history of the Opera (web browser), Opera web browser began in 1994 when it was started as a research project at Telenor, the largest Norwegian telecommunications company. In 1995, the project branched out into a separate company named Opera Software Allmennaksjeselskap, ASA, with the first publicly available version released in 1996. Opera has undergone extensive changes and improvements, and introduced notable features such as Speed Dial. Until version 2.0, the Opera browser was called MultiTorg Opera (version 1.0) and had only a limited internal release—although it was demonstrated publicly at the International World Wide Web Conference, Third International WWW Conference in April 1995. It was known for its multiple document interface (MDI) and 'hotlist' (sidebar), which made browsing several pages at once much easier, as well as being the first browser to completely focus on adhering to the World Wide Web Consortium, W3C standards. In February 2013, Opera Software anno ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
