 A) VLAN increase the number of broadcast domain.

Just for example - Take a switch of 12 ports.

As we everybody know that in a switch, 

Broadcast Domain - 1
Collision Domain - No of ports i.e. here it is 12. 
So in this condition, each port can communicate with each
other. in spite of having 1 broadcast domain & 12 collision
domain. 

Make two VLAN (Such as VLAN - 5 (Sachin), VLAN 6 (Dravid)on
that switch & assign SIX (1,2,3,4,5 & 6) ports of the switch
to VLAN 5 & assign rest of SIX (7, 8,9,10,11 & 12) on VLAN 6. 

Now port no 1 can't communicate with port 9 without any
router & inter VLAN routing. That means, Creating VLAN is
nothing but logical division of switch. Here we created 2
VLANs, So now there is two broadcast domain.


a) VLAN increase the number of broadcast domain.
b) VLAN reduce the size of broadcast domain.
