PICT
Probably not, because the two graphic formats have almost nothing in common. jpeg is used to effectively store generic images (like photos), dwg is used to store Autocad 3D graphics.
Images can be stored in JPG, TGA, or RAW formats, as well as several proprietary formats, such as NAR format used by Nokia.
There are 3 formats that are most used. There are more but the most common are: .png .jpg (same as .jpeg) .gif (for animated images)
The term "vector" in graphic design refers to a method of editing and file storage different than that of a bitmap format or editor. Vector files store information using paths, trajectories, and nodes; while bitmaps store information in an array or matrix.Furthermore, a vector illustration can be exported easily to a bitmap format, at which point it becomes un-editable using vector techniques. A bitmap can also be translated into a vector format, but that requires much more fine tuning and, in many cases, manual conversion via tracing.
Yes - for simple images like drawings, because they describe how to generate the image and do not store each pixel apart.
Free vector images are available from many online sources that store vector images. Fotolia and Vecteezy are just a few examples of free vector image websites.
Graphic library is a library that store various of graphic ( it can be vector or jpg, mostly it's some illutration, drawing, graphic element, also can be icon or pictogram ), people can create their own graphic library or download from online graphic stock website. If you working on a specify project or working for a specify brand, that company probably have their own graphic library for use.
Raster images are defined in pixels. ie At every x,y location, whether it is black or white. Vector images are defined by lines. eg From x,y to X,Y. Any pixel that lies between these points on a white background becomes black. It is easier to convert Vector images to Raster images, rather than the other way. Vector images are sometimes smaller (in data size). eg If the image contains one line, then the amount of data needed to store this is smaller than having to define every pixel in the image regardless of whether it is relevant. Vector images can be scaled smaller and larger without any significant loss of detail. Raster images that have been made smaller lose clarity and cannot then be made larger to improve the quality.
A Vector can store any objects, so yes.

RAM from graphic cards does not contribute to overall RAM on a computer. A graphic card that has RAM will only use that RAM for the use of the graphic card itself and no other parts of the computer. This means that the RAM that is on the graphic card is only used to store images that are being sent to the graphic card itself. The RAM on the graphic card allows the card to handle much more graphic intensive scenes, and puts a lot less stress on the graphic card, because instead of the graphic card having to process every bit of information for the scene that is sent to it. ( lets say your graphic card as 1GB of RAM on it ) The graphic card can store at least 1 GB of RAM in its memory to process later, allowing the card to finish processing the information that it was processing before the new information came in. Hope this helps.
