According to what I have found on Google,the ip address is an address that is assigned to you when you go online.But does my laptop has an IP address even if I don't go online ?
And does it have to do with the laptop serial number?
 
The IP address you see is the one you get. Depending on your service provider, and their options, you could have a Dynamic (changing) IP address or a Static (doesn't change) IP address. Some automatically give you a Static one, others make you pay extra for that.

It has absolutely nothing to do with the laptop's serial number. And, the IP address is there no matter if you connect to the internet or not. You could disconnect all devices from your internet and the address would still exist. It has nothing to do with the device(s), it is the services address.

Also, depending on your setup, if the laptops WiFi is turned on (or Ethernet is connected) then you are on the internet. Even if you aren't in your browser or using a program that accesses the internet.

Look at the IP address as a mail address.
Let's say you live at Main street 24 in a town called Mytown, in the State of Mystate, in the county Mycounty in the country, let's say, the USA.
If this address is a private home, then you and you alone will have this address.
If someone from, let's say, Japan should send you a letter and uses the above address, that letter will finally end up in your mailbox!
Even if you are not at home (similar to your computer not connected to the Internet) that address does exist. If you are not at home (computer is not online and connected to the Internet) you will not be able to take out the letter from the mailbox and read it. As soon as your computer is online, a certain IP address will be assigned to your computer via many hubs, switches and gateways (like post offices in the mail world) and your emailbox will be connected to that IP address so that email with your email address will finally be delivered to that IP address.
As long as your computer is not online, you will not be able to open the email that was sent to you via any mail server, regardless if you use a mail client program such as outlook or use a web browser and get your mail from f.i. Gmail.

You most likely have a router and are connected to this device either via cable or wifi. In any case, your router sets up a private network using one of three possible IP ranges:

    ■192.168.X.Y (X and Y can be any number between 0 and 255) This is the most popular and widely used possibility.
    ■172.16.X.Y (X can be any number between 16 and 32, while Y can be any number between 0 and 255)
    ■10.X.Y.Z (X, Y and Z can be any number between 0 and 255)

Your router obtains a certain IP address from your ISP which is the one you see when you ask Google. This is also called the public IP address and comes into your router at the WAN port
On the other side (usually 4 LAN ports) the router assigns IP addresses using its hardware which includes a DHCP server. Sometimes it is necessary to set a specific IP address in your PC/MAC/phone and thus you do not use the DHCP server of the router.
Thus ipconfig shows you the address your router has assigned to your host ( PC, MAC, laptop or phone). Or it shows the IP address that has been set in the network adapter of your host.
