Basically a network interface card is a component inside the computer that allows it to connect to a computer network. It is a piece built into the computer and is connected to a router via an Ethernet cable. How it works is that it’s connected to the router which gets supplied data from the internet service provider or ISP for short.
So what does the network interface card do? It changes data into something which can be used by the Ethernet cable to sent to another computer. This also converts data being given in a way that the CPU can use. This is the concept used to send emails with attachments. Through the Ethernet cable, information can be sent to another computer. To make it simple for you, the network interface card is like a telephone, when you connect it to your service provider they actually enable your phone settings and the ability to call other people, kind of like connecting your phone to a telephone network.
