What is meant by Network Interface Card (NIC)?

While creating VM in azure, NIC also created. Initially, I thought that both the virtual network and NIC are the same. Then I got to know that both are different. So, anyone of you kindly helps me to clarify this

Hi,

In Azure when you deploy a VM the following components gets deployed along :

NIC Network Security Group Public IP Disk

A NIC is a component which holds the Public IP and the private IP of the VM. Also you can associate the NSG to the NIC.

NIC can be deployed in a subnet of the Virtual Network.

Hope this helps!

VM needs at least one NIC, NIC connects VM to the VNet. One VM can have multiple NIC's as well.

A network interface enables an Azure Virtual Machine to communicate with internet, Azure, and on-premises resources. When creating a virtual machine using the Azure portal, the portal creates one network interface with default settings for you.

Network Interface Card (NIC) is assigned with IP address and associated with NSG rules, which is used for the communication between virtual machine's or internal network or internet.

Where as the virtual network (vNet) works on layer 3 and layer 4 for communication of traffic in secure way.
