The answer is in the question.
Basically an orbit will orbit the planet/moon while the lander lands on the surface.
Collecting and analyzing samples of soil and rock are fiendishly difficult operations for an orbiter, but are child's play for a lander.
The Viking 1 and Viking 2 missions consisted of both an orbiter and a lander. The lander landed on the surface of Mars to collect data and images.
the difference between a probe and a lander is a lander is a spacecraft that desends and comes to rest on the surface of a planet/space object. while a probe is a device used to collect items and run tests to collect data.

It was the Polar Lander and Climate Orbiter, not a rover. For both someone wrote part of the program in meters and another person wrote their portion in feet: the Climate Orbiter was 146 kilometers off and burned up. After patching the software on the Polar Lander it mislanded when it was less than 50 meters over the land. It flew 350 million kilometers and missed by only 40 something meters. BUT you have to hand it to them: it's like you flew around the world 2.3 times and landed 1.2 feet from the end of your parking spot.

The lander was used to land on planets and study the such as the moon and the orbiter was used to orbit the planet while studying it.

The main difference between a flyby spacecraft and an orbiter is the guidance computer programming: which causes a flyby to go by the planet and take pictures and other readings allowed in the limited time of the single pass, while an orbiter is captured into an orbit about the planet where it has a much longer period to take pictures and other readings.
