dots per inch (dpi) A measure of the visual resolution of a display or output

device. Monitor screens typically have resolutions in the

range of 70 to 75 dpi. Most common laser printers have a

resolution of 300 dpi. The lower the resolution of a page in

dots per inch, the lower the visual quality of characters on

that page. Pro OCR can quickly and accurately recognize

characters scanned in at resolutions down to 200 dpi.

consist of a base and a file extension, for example

SAMPLE.TXT. In this example, “SAMPLE” is the base, and

the file extension is “.TXT”. File extensions are used to

identify the type of file. In this example, the file extension

indicates that this is a text (ASCII) file.

file type Different applications create different file types. Some file
