The parameters used for evaluating the programs are assigned a graphical rating on a scale of five. These measures include performance, functions, and ease of use. The overall rating shown in the test result table is based on all these factors. In addition, there is a value for money rating for each application. This rating is obtained by compiling the features and the utility of the application against its price. In case of freeware and shareware tools available for downloading from the Internet, we replace the price with the download size (and therefore, the time taken to download the application) for arriving at the value for money rating.
