Downloading

 ‘Copy (data) from one computer system to another or to a disk’.((https://www.google.co.uk/#q=define+download)
The tech terms computer dictionary describe downloading as ‘This is the process in which data is sent to your computer. Whenever you receive information from the Internet, you are downloading it to your computer. For example, you might have to download an upgrade for your computer's operating system in order to play a new game (especially if you are using Windows). Alternatively, you might download a demo version of a program you are thinking about buying from the software company's Web site. The opposite of this process, sending information to another computer, is called uploading.’ (http://www.techterms.com/definition/download)
According to free on line dictionary download define as ‘transfer (software or data) from a computer to a smaller computer or a peripheral device.  (http://www.thefreedictionary.com/download)
‘Downloading is the transmission of a file from one computer system to another, usually smaller computer system. From the Internet user's point-of-view, to download a file is to request it from another computer (or from a Web page on another computer) and to receive it.’ (http://searchnetworking.techtarget.com/definition/downloading)

World English dictionary says ‘a file transferred onto a computer from another computer or the internet to copy or transfer (data or a program) into the memory of one computer system from a larger one)
‘The same dictionary define download as a verb to copy or transfer (data or a program) into the memory of one computer system from a larger one’ (http://dictionary.reference.com/browse/download)

Computing Dictionary define downloading as ‘To transfer data from one computer to another. Downloading usually refers to transfer from a larger "host" system (especially a server or mainframe) to a smaller "client" system, especially a microcomputer or specialised peripheral, and "upload" usually means from small to large.
Others hold that, technically, download means "receive" and upload means "send", irrespective of the size of the systems involved.
Note that in communications between ground and space, space-to-earth transmission is always "down" and the reverse "up", regardless of size. So far, the in-space machines have invariably been smaller; thus, the upload/download distinction has been reversed from its usual sense.

Streaming
The free encyclopaedia defines streaming as ‘Jump to: navigation, search
Streaming media is multimedia that is constantly received by and presented to an end-user while being delivered by a provider. Its verb form, "to stream", refers to the process of delivering media in this manner; the term refers to the delivery method of the medium rather than the medium itself’ http://en.wikipedia.org/wiki/Streaming_media

According to Website team (12th October 2012) ‘Streaming means listening to music or watching video in ‘real time’, instead of downloading a file to your computer and watching it later’
When it is streaming we do not need to download the file. It will help us to save space of the pc as we don’t need to download the program. We can just watch or listen to it. Different program and devices respond in a different way for streaming.
