The product, explained
About the DELL Inspiron 15 (3520)
DELL 3520-4572 is listed in the laptops category. The recorded specifications include display diagonal: 39.6 cm (15.6"); processor family: Intel® Core™ i3; internal memory: 4 GB; total storage capacity: 1 TB. This entry covers manufacturer code 3520-4572. Specifications relate to this exact source record; other editions or packages may differ.
The 39.6 cm (15.6") display is specified at 1366 x 768 pixels. Consider these together: a larger screen provides more physical space, while resolution determines the number of pixels available. Neither specification establishes brightness, colour accuracy or motion quality.
This configuration lists 4 GB of memory and 1 TB of storage. Memory supports active applications; storage holds software and files. Check upgradeability separately, because a capacity figure does not establish whether either component can be replaced.
