• check RAM requirements before purchasing the application

CPU requirements

• check the CPU requirements before purchasing the application

External hardware tokens

• USB stick to access application

1.10 distribution methods

Physical media vs downloadable

• physical uses DVD OR USBs

• Downloadable are EXE files downloadable from a site

ISO mountable
