You may consider the terms "geek" and "nerd" to be synonymous. While geeks and nerds share certain common traits (and it's possible to be both at once), there are distinct differences between the two groups.

Geek Definition

The word "geek" comes from the English and German words geek and geck, which mean "fool" or "freak". The German word geck survives to the present day and means "fool". In the 18th century Europe, Gecken were circus freaks.

In the 19th century, American geeks were still circus freaks, but they upped their game to include feats of freakishness, like biting the heads off of live rats or chickens. Modern geeks aren't known for acts of barbarism but retain a flair for eccentricity. They also tend not to be fools, unless you consider their penchant for bleeding edge tech to be foolish.

Modern Geek Definition: A person with an intense interest in one or more subjects. A geek will have encyclopedic knowledge about these topics and may be an avid collector of tech or memorabilia related to the areas of concern.

Nerd Definition

The word "nerd" first appeared in the 1951 Dr. Seuss poem "If I Ran the Zoo":

"Then the whole town will gasp, ‘Why this boy never sleeps! No keeper before ever kept what he keeps. There’s no telling what that young fellow will do!’ And then, just to show them, I’ll sail to Ka­troo  And bring back an It­Kutch a Preep and a Proo, A Nerkle, a Nerd and a Seersucker too." 

While Dr. Seuss may have coined the term, there was a 1940s slang word, nert, which meant "crazy person". Modern nerds could be considered borderline insane because they are characterized by an obsession with matters of interest. Typically, these are academic pursuits.

Modern Nerd Definition: An intellectual who is focused on learning all there is to know about one or more topics and mastering the skills of the discipline.

Some would say a nerd is a geek who either lacks social skills or else simply prefers solitary pursuits. Urban Dictionary definition: "a four-letter word with a six-figure income."
