In website hosting, the term "bandwidth" is often incorrectly used to describe the amount of data transferred to or from the website or server within a prescribed period of time, for example bandwidth consumption accumulated over a month measured in Gigabyte per month. The more accurate phrase used for this meaning of a maximum amount of data transfer each month or given period is monthly data transfer.
Consider this example:
• Rented Water Tank = web-server that hosts your website,
• Water company = hosting company where your web-server resides,
• Water = files, data, images, etc. that comprise your website,
• Pipe = the internet,
• Quantity of water delivered = bandwidth consumption,
• You = patron / visitor of your website which is hosted on aforementioned web-server.
There's a pipe that delivers water from your rented water tank to your home. As you request water, the water company delivers it to you. All the while, they are keeping track of how much water was delivered to you, during a billing cycle. You have a contract with the water company in which they agree to charge you a fixed dollar amount per billing cycle, provided you do not request more water than the allowable quantity, as defined in your contract. If you do request more water, they will not deny you ... but you will incur additional charges for the extra water requested / delivered.
With that example in mind, web-pages typically equate to a small quantity of water ... while images, videos, PDFs and other similar media can potentially equate to large quantities of water being delivered by your water company. The accumulated total can grow rather quickly, especially when your website is popular / visited by many people. Read more about: Bandwidth in web hosting
The Internet Protocol Suite (commonly known as TCP/IP) is the set of communications protocols used for the Internet and other similar networks. It is named from two of the most important protocols in it: the Transmission Control Protocol (TCP) and the Internet Protocol (IP), which were the first two networking protocols defined in this standard. Today's IP networking represents a synthesis of several developments that began to evolve in the 1960s and 1970s, namely the Internet and LANs (Local Area Networks), which emerged in the mid- to late-1980s, together with the advent of the World Wide Web in the early 1990s.
The Internet Protocol Suite, like many protocol suites, may be viewed as a set of layers. Each layer solves a set of problems involving the transmission of data, and provides a well-defined service to the upper layer protocols based on using services from some lower layers. Upper layers are logically closer to the user and deal with more abstract data, relying on lower layer protocols to translate data into forms that can eventually be physically transmitted.
The TCP/IP model consists of four layers (RFC 1122). From lowest to highest, these are the Link Layer, the Internet Layer, the Transport Layer, and the Application Layer. Read more about: Internet Protocol Suite
Video capture is the process of converting an analog video signal—such as that produced by a video camera or DVD player—to digital form. The resulting digital data are referred to as a digital video stream, or more often, simply video stream. This is in contrast with screencasting, in which previously digitized video is captured while displayed on a digital monitor.
==Process== by abhijeet The video capture process involves several processing steps. First the analog video signal is digitized by an analog-to-digital converter to produce a raw, digital data stream. In the case of composite video, the luminance and chrominance are then separated; this is not necessary for S-Video sources. Next, the chrominance is demodulated to produce color difference video data. At this point, the data may be modified so as to adjust brightness, contrast, saturation and hue. Finally, the data is transformed by a color space converter to generate data in conformance with any of several color space standards, such as RGB and YCbCr. Together, these steps constituted video decoding, because they "decode" an analog video format such as NTSC or PAL.
Special electronic circuitry is required to capture video from analog video sources. At the system level this function is typically performed by a dedicated video capture card. Such cards often utilize video decoder integrated circuits to implement the video decoding process. Read more about: Video capture
In computer networking and computer science, digital bandwidth, network bandwidth or just bandwidth is a measure of available or consumed data communication resources expressed in bit/s or multiples of it (kbit/s, Mbit/s etc).
Bandwidth may refer to bandwidth capacity or available bandwidth in bit/s, which typically means the net bit rate, channel capacity or the maximum throughput of a logical or physical communication path in a digital communication system. For example, bandwidth test implies measuring the maximum throughput of a computer network. The reason for this usage is that according to Hartley's law, the maximum data rate of a physical communication link is proportional to its bandwidth in hertz, which is sometimes called frequency bandwidth, radio bandwidth or analog bandwidth, the last especially in computer networking literature.
Bandwidth may also refer to consumed bandwidth (bandwidth consumption), corresponding to achieved throughput or goodput, i.e. average data rate of successful data transfer through a communication path. This meaning is for example used in expressions such as bandwidth shaping, bandwidth management, bandwidth throttling, bandwidth cap, bandwidth allocation (for example bandwidth allocation protocol and dynamic bandwidth allocation), etc. An explanation to this usage is that digital bandwidth of a bit stream is proportional to the average consumed signal bandwidth in Hertz (the average spectral bandwidth of the analog signal representing the bit stream) during a studied time interval.
Digital bandwidth may also refer to: average bitrate (ABR) after multimedia data compression (source coding), defined as the total amount of data divided by the playback time.
Some authors prefer less ambiguous terms such as gross bit rate, net bit rate, channel capacity and throughput, to avoid confusion between digital bandwidth in bits per second and analog bandwidth in he Read more about: Bandwidth
Curl is a reflective object-oriented programming language designed for interactive web applications. It combines text markup (as in HTML), scripting (as in JavaScript), and heavy-duty computing (as in Java, C#, or C++) within one unified framework. It is used in a range of internal enterprise, B2B, and B2C applications.
Curl is a markup language like HTML—that is, plain text is shown as text; at the same time, Curl includes an object-oriented programming language that supports multiple inheritance. Curl applications are not required to observe the separation of information, style, and behavior that HTML, CSS, and JavaScript have imposed, although that style of programming can be used in Curl if desired.
While the Curl language can be used as an HTML replacement for presenting formatted text, its capabilities range all the way to those of a compiled, strongly typed, object-oriented system programming language.[1] Both the authoring (HTML-level) and programming constructs of Curl can be extended in user code. The language is designed so Curl applications can be compiled to native code of the client machine by a just-in-time compiler and run at high speed.
Curl applets are viewed using the Curl RTE, a runtime environment with a plugin for web browsers. Currently, it is supported on Microsoft Windows, Linux, and Macintosh.
Curl has had a feature of "detached applets" for several years, which is a web deployed applet which run on the user's desktop independent of a browser window much as in Silverlight 3 and Adobe AIR. Curl applets can also be written so that they will run off-line when disconnected from the network (occasionally-connected computing). In fact, the Curl IDE is an application written in Curl.
