Pixel And Resolution 

In digital imaging, a pixel, or picture element is a physical point in a raster image, or the smallest addressable element in an all points addressable display device; so it is the smallest controllable element of a picture represented on the screen.

Image resolution is the detail an image holds. The term applies to raster digital images, film images, and other types of images. Higher resolution means more image detail.

Image resolution can be measured in various ways. Basically, resolution quantifies how close lines can be to each other and still be visibly resolved. Resolution units can be tied to physical sizes, to the overall size of a picture

Vector And Raster Images

Vector graphics is the use of geometrical primitives such as points, lines, curves, and shapes or polygon, which are all based on mathematical expressions, to represent images in computer graphics. Vector graphics are based on vectors (also called paths, or strokes) which lead through locations called control points. Each of these points has a definite position on the x and y axes of the work plan.

In computer graphics, a raster graphics image, or bitmap, is a dot matrix data structure representing a generally rectangular grid of pixels, or points of color, view able via a monitor, paper, or other display medium. Raster images are stored in image files with varying formats.

File Formats And Uses -  bmp, png, gif, tiff, jpg, psd, pdf, eps and ai

file formats are standardized means of organizing and storing digital images. Image files are composed of digital data in one of these formats that can be rasterized for use on a computer display or printer. An image file format may store data in uncompressed, compressed, or vector formats. Once rasterized, an image becomes a grid of pixels, each of which has a number of bits to designate its color equal to the color depth of the device displaying it.

Compression 
Compression is basically when you make  a larger thing like a file smaller this is used allot within the games industry not only to save but to enable more files to be saved on one thing rather than having the full file being saved. this is used allot but can also be extremely useful when it comes to saving space and to enable you to have more saved files on one thing rather spread out on a number of things. Compression can also be the volume of a sound weather it would be loud or quite either way it dose not matter but it is relevant to the compression of the sound or file.  

Storage And Asset Management 

Digital asset management (DAM) consists of management tasks and decisions surrounding the ingestion, annotation, cataloging, storage, retrieval and distribution of digital assets. Digital photographs, animations, videos and music exemplify the target areas of media asset management (a sub-category of DAM). Digital asset management systems (DAMS) include computer software and hardware systems that aid in the process of digital asset management.
