Open the Packet Tracer and drag the devices to the working sheet as shown in the figure below.

Assign the IP address to every device as shown in the figure.

Figure: PC ip seating

Assign IP addresses to the interfaces of your routers. Use the config terminal command on each router to enter global configuration mode, then use the interface [interface_type] [interface_number] command to access the interface configuration mode. Finally, assign the IP address using the ip address [ip_address] [subnet_mask] command.

Router>enable

Router#

Router#configure terminal

Router(config)#interface GigabitEthernet0/0/0

Router(config-if)#no shutdown

Router(config-if)#ip address 192.168.1.1 255.255.255.0

Router(config-if)#exit

Router(config)#exit

Router#

Similarly, configure the 2nd interface for 2nd network

Router>enable

Router#

Router#configure terminal

Router(config)#interface GigabitEthernet0/0/1

Router(config-if)#no shutdown

Router(config-if)#ip address 192.168.2.1 255.255.255.0

Router(config-if)#exit

Router(config)#exit

Router#

Now you have to set the default gateway to make the communicaiton possible. Go to every pc ip setting and enter the router interface address. After entering the router interface address, the PC will be able to communicate.
