Stock Chart Real Time
You're looking at a stock chart in real time, and it's continuously updating itself with changes to the stock's price, like a wave passing across your screen. This is what they call real time numbers, because they're as close to instantaneous pricing happening on the exchange floor as you're going to get unless you're standing there yourself. One of the ways this is accomplished is through streaming. Streaming media are any type of multimedia that are continuously received by and delivered to a user by a streaming provider. The term refers to the distribution method of the medium; not the medium itself. The term is usually used for media that are distributed over telecommunications networks, since most other delivery systems are either naturally streaming - such as radio and television - or non-streaming, such as books, DVDs and audio CDs. The verb 'to stream' is a derivative of this term and means to deliver media in this manner. Internet television is a streamed media.
Very little progress was made in the attempt to show media on computers for several decades in the mid twentieth century, mostly because of the high cost and limited capabilities of computer hardware.
Starting in the late 1980s and throughout the 1990s, personal computers finally became sophisticated enough to display different types of media. The main issues related to streaming were having enough power and bandwidth to support the amount of flowing data; and making a concealed path in the operating system to process and prevent buffer under run.
Despite these advances, computer networks were still inadequate. Media was still usually delivered through non-streaming conduits, such as downloading a file from the internet and saving it to a local drive or playing it off of CD-ROMs.
In the late 90s and early 2000s, the internet progressed to a point of greater bandwidth, increased network access, increased use of standardized protocols and coding language and commercialization of the internet. The progression in computer networking put together with even more powerful personal computers and updated operating systems made streaming media practical and affordable for the average consumer.
Today, increased demand for streaming of high definition (HD) subject matter to a number of devices in the home has led to the development of numerous technologies, such as Wireless HD, which allows for streaming HD content without requiring the user to put in new networking cables.
