Dell Latitude Notebook Laptop

The Dell Latitude series is a line of laptop computers manufactured and sold by American company Dell. It is a business-oriented line, aimed at corporate enterprises, healthcare, government, and education markets; unlike the Inspiron series, which is aimed at individual customers, and the Vostro series, which is aimed at smaller businesses. The Latitude directly competes with the Lenovo ThinkPad and the EliteBook series by HP. Additionally, the "Rugged (Extreme)", "XFR" and "ATG" models compete primarily with Panasonic's Toughbook line of "rugged" laptops.

Dell Latitude computers are also differentiated in their feature sets, due to their business focus. For example, they often include security features such as smartcard and contactless smartcard, and TPM security, vPro and AMD Dash management, DisplayPort (as opposed to HDMI), Docking stations and support for legacy standards are all results of the requirements of the business market.
