Jain Dharma is traditionally divided into two main sects:

1) Digambar

Meaning: “Sky-clad” — emphasis on complete renunciation.

Main sub-sects of Digambar:

• Bispanthi
• Terapanthi
• Taranpanthi
• Gumanpanthi
• Kanjipanthi

2) Shwetambar

Meaning: “White-clad” — monks wear white clothes.

Main sub-sects of Shwetambar:

• Murtipujak

- also known as Deravasi - includes many temple-oriented traditions

• Sthanakvasi

- do not worship idols

• Terapanthi

- a reformist sect of Shwetambar

• Gachchhas within Murtipujak tradition, such as:

- Khartar Gachchha - Tapagachchha - Achapagachchha - Panchasara Gachchha

Very simple summary:

• Digambar = major Jain sect with several sub-sects
• Shwetambar = major Jain sect with several sub-sects
• The differences are mainly in monastic practice, clothing, temple worship, and spiritual discipline

If you want, I can also give you a very short comparison table of Digambar and Shwetambar.
