laborious adj.: operose
Computers and the Internet offer unprecedented access to a world of information. Rather than becoming obsolete, basic skills such as spelling, referencing source material and typing are vital in maneuvering one’s way efficiently through the electronic multimedia landscape. With three splendiferous CD-ROMs, users can complete these operose tasks expediently and efficiently.
