Device used to read digital resources such as e-books and e-journals. It is a portable device that permits to store a great quantity of digital documents; it allowsalso direct e-books' download trough wifi systems. E-reader screens are designed to allow the users a comfortable reading.
software: it is not a software, as far as I know, but a device which obviously requires some software in order to work.
resoruces: resources (just a mistype, obviously :))
storaging: I found some cases on the web, but the main language dictionaries do not have this entry. I would say "permits to store", "allows to store" or "permits the storage of".
permits: Note that permit strongly stresses the "give permission to" while "allow" also means "make it possible to..."
from: I suggest "through wi-fi networks", "from" a publisher's website
