EPS stands for Encapsulated PostScript. Files of this format have an .eps extension. The file extension was developed by Adobe Systems in 1992. It is a standard format used to import and export a single page of formatted text, images and graphics. EPS files can be placed with another Postscript file. Commonly used in the publishing industry, an advantage of .EPS is that they are Operating System independent, meaning that the file type can be used to send image and graphics to another recipient regardless of OS. Most EPS files contain a bitmap preview. This allows applications that cannot interpret postscript code to render a low resolution version of the file.
An EPS file must contain at least two DSC (Document Structuring Conventions) header comments. One that confirms that the file conforms to Version 3.0 of the EPS format and also a Bounding Box comment. The Bounding Box comment defines the values that indicate the size of the image to the application reading the file. A number of optional DSC comments can be added depending on the nature of the EPS. For example the %%Begin(End)Preview denotes the bitmap preview section of the file. Another common optional comment is the %%Extensions: comment. This is used to define language extension requirements. The comments section is also used to denote specific font requirements. Note that including multiple extensions limits the portability of the file and therefore where possible an EPS file should be self contained.

Tiff was originally created by a company called Aldus, and is now owned by Adobe systems, it is a file format for storing images, including line art and photographs. It was created due to the popularity of scanners and was thought-up to become the standard scanned image file format. It is a popular format for high-colour-depth images and it has also been adapted to accommodate greyscale images.
A TIFF file is made up of many different blocks which define the palette data or the LZW-compressed body among other things. The byte order is either Motorola or Intel depending on the first word. if it is MM, then you have Motorola byte ordering and likewise if it is II it means you have Intel byte ordering. Each TIFF file begins with an image file header which then points to an image file directory which contains the image data and image information.
