Web Accelerator
A web accelerator is a proxy server that reduces website access time. They can be a self-contained hardware appliance or installable software. Web accelerators may be installed on the client computer or mobile device, on ISP servers, on the server computer/network, or a combination. Accelerating delivery through compression requires some type of host-based server to collect, compress and then deliver content to a client computer. Web accelerators may use several techniques to achieve this reduction in access time: They may: *cache recently or frequently accessed documents so they may be sent to the client with less latency or at a faster transfer rate than the remote server could. *freshen objects in the cache ensuring that frequently accessed content is readily available for display. *preemptively resolve hostnames present in a document (HTML or JavaScript) in order to reduce latency. * prefetch documents that are likely to be accessed in the near future. *compress documents ...

Proxy Server
In computer networking, a proxy server is a server application that acts as an intermediary between a client requesting a resource and the server providing that resource. Instead of connecting directly to a server that can fulfill a request for a resource, such as a file or web page, the client directs the request to the proxy server, which evaluates the request and performs the required network transactions. This serves as a method to simplify or control the complexity of the request, or provide additional benefits such as load balancing, privacy, or security. Proxies were devised to add structure and encapsulation to distributed systems. A proxy server thus functions on behalf of the client when requesting service, potentially masking the true origin of the request to the resource server. Types A proxy server may reside on the user's local computer, or at any point between the user's computer and destination servers on the Internet. A proxy server that passes unmodified r ...

Transmission Control Protocol
The Transmission Control Protocol (TCP) is one of the main protocols of the Internet protocol suite. It originated in the initial network implementation in which it complemented the Internet Protocol (IP). Therefore, the entire suite is commonly referred to as TCP/IP. TCP provides reliable, ordered, and error-checked delivery of a stream of octets (bytes) between applications running on hosts communicating via an IP network. Major internet applications such as the World Wide Web, email, remote administration, and file transfer rely on TCP, which is part of the Transport Layer of the TCP/IP suite. SSL/TLS often runs on top of TCP. TCP is connection-oriented, and a connection between client and server is established before data can be sent. The server must be listening (passive open) for connection requests from clients before a connection is established. Three-way handshake (active open), retransmission, and error detection adds to reliability but lengthens latency. Applica ...

NetJet
NetJet was the first commercially available web accelerator. The product was developed by Peak Technologies (changed in 1997 to PeakSoft Multinet Corp.) in 1996 and released in November 1996 at COMDEX in Las Vegas Nevada. NetJet was named a 'Best in Show' product in the internet category. NetJet was derived from the ExpressO Java Server designed and developed by Charles T. ("Chuck") Russell the founder of Innovative Desktop Inc. a Delaware corporation acquired by Peak Technologies in June, 1996. ExpressO was the first widely distributed, commercially available java application server. NetJet features provided better response time and enhanced download speeds for web browsers by performing work in the background. NetJet caused a stir in the World Wide Web community in December 1996 when CNET magazine wrote: "Web accelerators--one of the hottest tools on the Internet--are supposed to make life easier for Net surfers, but they are causing some headaches for Web site operators."

Google Web Accelerator
Google Web Accelerator was a web accelerator produced by Google. It used client software installed on the user's computer, as well as data caching on Google's servers, to speed up page load times by means of data compression, prefetching of content, and sharing cached data between users. The beta, released on May 4, 2005, works with Mozilla Firefox 1.0+ and Internet Explorer 5.5+ on Windows 2000 SP3+, Windows XP, Windows Server 2003, Windows Vista and Windows 7 machines. Bugs and privacy issues It was discovered that Google Web Accelerator had a tendency to prevent YouTube videos from playing, with the message in the YouTube video player, "We're sorry, this video is no longer available." By turning off Google Web Accelerator, the user was able to play YouTube videos again without a problem. Google Web Accelerator sent requests for web pages, except for secure web pages (HTTPS), to Google, which logged these requests. Some web pages embedded personal information in these page ...

Netscape
Netscape Communications Corporation (originally Mosaic Communications Corporation) was an American independent computer services company with headquarters in Mountain View, California and then Dulles, Virginia. Its Netscape web browser was once dominant but lost to Internet Explorer and other competitors in the so-called first browser war, with its market share falling from more than 90 percent in the mid-1990s to less than 1 percent in 2006. An early Netscape employee Brendan Eich created the JavaScript programming language, the most widely used language for client-side scripting of web pages and a founding engineer of Netscape Lou Montulli created HTTP cookies. The company also developed SSL which was used for securing online communications before its successor TLS took over. Netscape stock traded from 1995 until 1999 when the company was acquired by AOL in a pooling-of-interests transaction ultimately worth US$10 billion.

America Online
AOL (stylized as Aol., formerly a company known as AOL Inc. and originally known as America Online) is an American web portal and online service provider based in New York City. It is a brand marketed by the current incarnation of Yahoo! Inc. The service traces its history to an online service known as PlayNET. PlayNET licensed its software to Quantum Link (Q-Link), who went online in November 1985. A new IBM PC client launched in 1988, eventually renamed as America Online in 1989. AOL grew to become the largest online service, displacing established players like CompuServe and The Source. By 1995, AOL had about three million active users. AOL was one of the early pioneers of the Internet in the mid-1990s, and the most recognized brand on the web in the United States. It originally provided a dial-up service to millions of Americans, pioneered instant messaging, and in 1993 began adding internet access. In 1998, AOL purchased Netscape for $4.2 billion. In 2001, at the height ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Small And Medium Enterprises
Small and medium-sized enterprises (SMEs) or small and medium-sized businesses (SMBs) are businesses whose personnel and revenue numbers fall below certain limits. The abbreviation "SME" is used by international organizations such as the World Bank, the European Union, the United Nations, and the World Trade Organization (WTO). In any given national economy, SMEs sometimes outnumber large companies by a wide margin and also employ many more people. For example, Australian SMEs makeup 98% of all Australian businesses, produce one-third of the total GDP (gross domestic product) and employ 4.7 million people. In Chile, in the commercial year 2014, 98.5% of the firms were classified as SMEs. In Tunisia, the self-employed workers alone account for about 28% of the total non-farm employment, and firms with fewer than 100 employees account for about 62% of total employment. The United States' SMEs generate half of all U.S. jobs, but only 40% of GDP. Developing countries tend to have a lar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
PaaS
Platform as a service (PaaS) or application platform as a service (aPaaS) or platform-based service is a category of cloud computing services that allows customers to provision, instantiate, run, and manage a modular bundle comprising a computing platform and one or more applications, without the complexity of building and maintaining the infrastructure typically associated with developing and launching the application(s); and to allow developers to create, develop, and package such software bundles. Development and uses PaaS can be delivered in three ways: * As a public cloud service from a provider, where the consumer controls software deployment with minimal configuration options, and the provider provides the networks, servers, storage, operating system (OS), middleware (e.g. Java runtime, .NET runtime, integration, etc.), database and other services to host the consumer's application. * As a private service (software or appliance) behind a firewall. * As software deploye ...

Software As A Service
Software as a service (SaaS ) is a software licensing and delivery model in which software is licensed on a subscription basis and is centrally hosted. SaaS is also known as "on-demand software" and Web-based/Web-hosted software. SaaS is considered to be part of cloud computing, along with infrastructure as a service (IaaS), platform as a service (PaaS), desktop as a service (DaaS), managed software as a service (MSaaS), mobile backend as a service (MBaaS), data center as a service (DCaaS), integration platform as a service (iPaaS), and information technology management as a service (ITMaaS). SaaS apps are typically accessed by users of a web browser (a thin client). SaaS became a common delivery model for many business applications, including office software, messaging software, payroll processing software, DBMS software, management software, CAD software, development software, gamification, virtualization, accounting, collaboration, customer relationship management (CR ...

Streaming Media
Streaming media is multimedia that is delivered and consumed in a continuous manner from a source, with little or no intermediate storage in network elements. ''Streaming'' refers to the delivery method of content, rather than the content itself. Distinguishing delivery method from the media applies specifically to telecommunications networks, as most of the traditional media delivery systems are either inherently ''streaming'' (e.g. radio, television) or inherently ''non-streaming'' (e.g. books, videotape, audio CDs). There are challenges with streaming content on the Internet. For example, users whose Internet connection lacks sufficient bandwidth may experience stops, lags, or poor buffering of the content, and users lacking compatible hardware or software systems may be unable to stream certain content. With the use of buffering of the content for just a few seconds in advance of playback, the quality can be much improved. Livestreaming is the real-time delivery of co ...

Compression Artifacts
A compression artifact (or artefact) is a noticeable distortion of media (including images, audio, and video) caused by the application of lossy compression. Lossy data compression involves discarding some of the media's data so that it becomes small enough to be stored within the desired disk space or transmitted (''streamed'') within the available bandwidth (known as the data rate or bit rate). If the compressor cannot store enough data in the compressed version, the result is a loss of quality, or introduction of artifacts. The compression algorithm may not be intelligent enough to discriminate between distortions of little subjective importance and those objectionable to the user. The most common digital compression artifacts are DCT blocks, caused by the discrete cosine transform (DCT) compression algorithm used in many digital media standards, such as JPEG, MP3, and MPEG video file formats. These compression artifacts appear when heavy compression is applied, and occu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Broadband
In telecommunications, broadband is wide bandwidth data transmission which transports multiple signals at a wide range of frequencies and Internet traffic types, that enables messages to be sent simultaneously, used in fast internet connections. The medium can be coaxial cable, optical fiber, wireless Internet (radio), twisted pair or satellite. In the context of Internet access, broadband is used to mean any high-speed Internet access that is always on and faster than dial-up access over traditional analog or ISDN PSTN services. Overview Different criteria for "broad" have been applied in different contexts and at different times. Its origin is in physics, acoustics, and radio systems engineering, where it had been used with a meaning similar to "wideband", or in the context of audio noise reduction systems, where it indicated a single-band rather than a multiple-audio-band system design of the compander. Later, with the advent of digital telecommunications, the term was mainly ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
