user16965: I am trying to receive and send some data from a computer to an ATtiny through USB. Can an ATtiny85 IC communicate with a computer through USB? If yes, how should it be connected?

Have you checked the web? There are many such projects. Here is a link to one:

Please remember "Google is your friend".
Cheers!

user10794: Digispark made a lot of these as part of a "cheap Arduino USB interface" project a while back.
This is my Digispark, it's pretty cute:

They have a web page here.

I got them for about $2 each. The board has the ATtiny85, a voltage regulator, and a handful of other parts.
