Download To receive a file transmitted over a network. In any communications session, "download" means receive, and "upload" means send. The time it takes to download data depends on the size of the file and network speed. Via the standard V.92 analog dial-up modem, small Web pages take a few seconds if everything is running smoothly, but a 10MB video file can take a half hour. Downloading over DSL or cable modem can be up to 100 times faster. Downloading from a file server on your local network (LAN) can be faster yet. Click to Download Downloading files from the Internet has become a snap with "click here to download this file" messages on Web pages. Your Web browser prompts you where to save the file. If the file is software that has to be installed, most browsers give you the option of running the program without worrying about where to save it first. See download protocol. On a Local LAN On a network server in your company's LAN, sharable files are placed in public folders that can be downloaded using the normal file management procedures of the operating system. For example, in a Windows LAN, My Network Places or Network Neighborhood can be used to locate sharable files by computer name, drive letter, folder and file name.

Uploading and downloading This article is about the computer terms. Download is also an industrial band led by CEvin Key. Download is also a British heavy metal festival. Uploading is also a hypothetical transfer of a human mind into a computer. The terms upload and download often create confusion, as their definitions depend on the context. Download and upload refer to the transfer of information between computers. The person/computer sending the information refers to the transfer as an upload, while the person/computer receiving the information refers to it as a download. These are the definitions used by ISPs. If the customer is sending information, it is an upload; if they are receiving information, it is a download. Most people use the term download when they are receiving a file, and upload when they are sending a file over the Internet. In either case, information is transferred both ways to manage the download. This is often the reason people get confused. The act of transferring a file from one web server to another, while technically a simultaneous download and upload, is often called sideloading. An exception is when talking about data transfers between space vehicles and ground stations; in this case, every transfer from the space vehicle is a download, while every transfer to it is an upload. As a noun, a download or upload is the information transferred or the act of transferring it. In surfing the World Wide Web the term downloading is not usually used for simply bringing up a web page, but rather for transferring a larger file and/or directly saving it. In a network, the term downloading is not usually used for copying files from one network device to another even if one computer is acting as a host (see copy.)

Rendering Rendering is the final process of creating the actual 2D image or animation from the prepared scene. This can be compared to taking a photo or filming the scene after the setup is finished in real life. Photo-realistic image quality is often the desired outcome, and to this end several different, and often specialized, rendering methods have been developed. These range from the distinctly non-realistic wireframe rendering through polygon-based rendering, to more modern techniques such as: scanline rendering, raytracing or radiosity. Rendering software may simulate such cinematographic effects as lens flares, depth of field or motion blur. These artifacts are, in reality, a by-product of the mechanical imperfections of physical photography, but as the human eye is accustomed to their presence, the simulation of such artifacts can lend an element of realism to a scene. Techniques have been developed for the purpose of simulating other naturally-occurring effects, such as the interaction of light with atmosphere, smoke, or particulate matter. Examples of such techniques include particle systems (which can simulate rain, smoke, or fire), volumetric sampling (to simulate fog, dust and other spatial atmospheric effects), and caustics (to simulate light focusing by uneven light-refracting surfaces, such as the light ripples seen on the bottom of a swimming pool). The rendering process is known to be computationally expensive, given the complex variety of physical processes being simulated. Computer processing power has increased rapidly over the years, allowing for a progressively higher degree of realistic rendering. Film studios that produce computer-generated animations typically make use of a render farm to generate images in a timely manner. However, falling hardware costs mean that it is by no means impossible to create small amounts of 3D animation on a home computer system. Often renderers are included in 3D software packages, but there are some rendering systems that are used as plugins to popular 3D applications. These rendering systems include Final-Render, Brazil r/s, V-Ray, Mental Ray and Pixar Renderman. The output of the renderer is often used as only one small part of a completed motion-picture scene. Many layers of material may be rendered separately and combined into the final version using traditional cinematic tools.
