Difference between 'finger' and 'who'

Hi,
I found that the output of these two commands, finger & who, are different. Actually, I found the users list from who is bigger than the one from finger command. Why is there a difference ? What is the occasion to use one from the other ?

Thx.

who shows you the list of logged in users, while finger is a lookup tool for a user, whether logged in or not. If you just type finger without anything it will show you the information about the current user. but you can specify the information of another user like finger user. You can put .finger file in your home directory that would show additional informaiton about you whenever someone type finger yourname.

for details see man finger and man who
