How to interpret access log of Apache server?

Question

I checked this link but could understand as they have provided with a different format.

This is an entry in my access log.

127.0.0.1 - - [13/Aug/2012:13:39:53 +0530] "GET /cgi-bin/test.cgi HTTP/1.1" 200 48

I want to know the meaning of the last code. I know that 200 id OK status code but what is 48 or any other number.... ?

Please help!

Answer 1

i think it means the size in bytes ..
