Final answer:
The TCP/IP stack is commonly used for protocols and referencing layers in network communication.
Step-by-step explanation:
When talking about protocols and referencing layers, the stack that is commonly used is the TCP/IP (Transmission Control Protocol/Internet Protocol) stack. This stack is widely used for network communication and forms the foundation for the internet. It consists of multiple layers, each responsible for different aspects of data transmission and communication.
The OSI (Open Systems Interconnection) model is another networking model that consists of seven layers, providing a framework for understanding how different protocols interact. However, TCP/IP is more commonly used in practice.
DNS (Domain Name System) is a protocol used to translate domain names into IP addresses, while HTTP (Hypertext Transfer Protocol) is a protocol used for communication between web browsers and web servers.
