The Traveller universe is set in a huge fictional empire called the Imperium, spanning immense distances of one spiral arm of the galaxy. Ruled by an Emperor (Strephon), and a heirachy of nobles below that, individual worlds are allowed their own governments and laws, as long as they obey the code of the Imperium, most of which applies to interstellar crimes and weapons of mass destruction.
The Imperium comprises many thousand star systems, and all progress at their own pace as regards development, culture and technology, though interstellar trade is a major influence on most.
Traveller is set in the 57th Century. Man has spread to the stars, both from Earth and from other planets to which he was transplanted 300,000 years ago by the mysterious Ancients. Dates are expressed in the dating system of the Third (current) Imperium; it's 1110 by that reckoning. The Imperial Calendar uses day numbers, so Jan 4th is 004/1110. The Fifth Frontier War between the Imperium and the Zhodani has just ended and a flood of demobilized service personnel are foot-loose and fancy free.
Star travel is by means of Jump drives, devices which can throw a starship between one and six parsecs (3.26 light years) in around a week. There is no faster method of communication between star systems; regular communication is carried by starships, particularly the XBoat network run by the Scouts.
This means that there is far less central control of decisions and far more autonomy for local planetary authorities to make them. It also means that the unscrupulous can commit crimes and escape justice by getting far enough away. Depending on how keen the pursuit is!
Surrounding the Imperium are several other star empires. The races that control these are among the Major Races - those that discovered Jump Drive on their own rather than being sold it by other races.

Note this list uses hexadecimal numbering. This is common in Traveller so as to allow larger numbers to be expressed in a single symbol.
Many people of many races roam the stars. Such travellers may be traders, plying single ships from system to system, or mercenaries, fighting for one planetary faction or another, or scouts, forever looking beyond the next hill.
One definition states: "A Tourist journeys to distant and interesting places and frequently gets into trouble. A Traveller journeys to distant and interesting places and frequently gets into trouble - and gets themselves out again."
Player characters are typically experienced individuals who have served in the armed forces of either a world or the Imperium itself, have acquired skills and benefits, and have for one reason or another set out to travel the galaxy and find adventure and employment in more interesting places. They can also be interstellar traders who have come from a merchant background, or criminals, or gamblers, or explorers... or pretty much anything. Unlike many other RPGs, Traveller characters typically start off with a significant level of skill.
