A network stack, also known as a TCP/IP stack, is a set of protocols that work together to enable network communication. It is a layered architecture, with each layer responsible for a specific aspect of communication. Common layers include the physical layer, data link layer, network layer, transport layer, and application layer. Each layer provides services to the layer above it and receives services from the layer below it. Network stacks are fundamental to how devices communicate over networks like the internet, allowing applications to send and receive data regardless of the underlying hardware or network infrastructure.
