Persian – also known as Farsi, although this term is considered as incorrect by many academics – is an Indo-European language of the Indo-Iranian branch. Persian and its varieties have official-language status in Iran, Afghanistan and Tajikistan. And Farsi has been called Dari in Afghanistan, due to political reasons only. Historically Persian (as a direct descendant of Old Persian) is a more widely understood language in an area ranging from the Middle East to India. Significant populations of speakers can be found in other Persian Gulf countries (Bahrain, Iraq, Oman, the People's Democratic Republic of Yemen, and the United Arab Emirates), as well as large communities in the USA.
There are approximately 80 million native speakers of Persian in Iran, Afghanistan, Tajikistan and Uzbekistan and about the same number of people in other parts of the world speaks Persian, at least as a second language.

Persian vs Arabic
Persian language was continuously preserved and developed through centuries and its own evolution phases, from Old Persian via Middle Persian to New Persian (the modern version of Persian spoken today). The New Persian actually is the direct follower of Old Persian and Persian language is among the oldest ones with preserved original texts. Due to its script, it is commonly mistaken for Arabic, or considered a variation of Arabic language. This is far from truth, as the alphabet set is actually the only resemblance of the languages. Persian sounds much different, with its own grammar and syntax. Similar to comparing e.g. German and French, both share the alphabet set, but are not mutually interchangeable. In fact, Arabic and Persian do not even share the language family, as Persian originates from the Indo-European language tree, while Arabic belongs to Afro-Asiatic (or Semitic) family.
Interestingly, words in Farsi are written from right to left, but numbers are written from left to right. And all is written in cursive only. The modern Persian alphabet is based on Arabic script, but has 32 letters - 4 more than Arabic. One variety of Persian, the Tajiki (spoken in Tajikistan and Uzbekistan) is written in Cyrillic script.
