Difference between share split and bonus issue issue

SWASH

I know in both the cases the comapny`s mkt cap remains the same....
Priced is adjusted according to the ratio....
Number of shares outstanding gets increased/decresed according to the ratio....
Bonus issue is an indication of the bullishness....
The only differences is the paid up capital....

Question 1 : In Bonus issue the paid up capital increases....HOW ?????
Question 2 : In stock split the Paid up Capital remains the same...How??
Question 3 : is the Face value adjusted?...Yes/No

Can some one pls explain and correct me if Im wrong n my assumptions


Thanks in advance!!!!!!!
