How to start feeding data

[sanktusm]

Hi,
I am a litte confued about the import features
when i start feeding leads the account name is not displayed and the data appears not in the account table
when i feed contacts the Account Name is displayed and the data appears in the account table
I tried to start with feeding an Account but there is no option for Account Names

My Question How to start feeding data? What is a Account Name? why is there not a field named company name?

Leads are not related with Accounts.

A Lead is a not-yet-contact which has no relation to Accounts but only an accountname in its local fields.
