Network problem

[01071981]

Hi All,
I am new to networking and just had one query
I have 2 networks
10.5.20.1
255.255.255.0
and
10.5.120.1
255.255.255.0

My question is that these 2 network will communicate with each other or not.
If some one can provide the brief descripton also that will be great.
waiting for a quick reply.

By default, these two networks do not talk to each other without the help of a layer 3 network device. This is classicaly a router, but can call be a switch that handles layer 3. It's only one of these devices that can provide a path of communication between separate networks.
