supply chain:

. . . a distribution channel accommodating the business process of supplying material or components through a manufacturer to one or more stop points with the intent to deliver ultimately to a customer as end user; likewise, a process of providing related services. It is a chain-like system that moves deliverables from one point to the next.

Deliverables are defined as tangibles, such as goods and services, or intangibles, such as information, transported or conveyed to recipients or locations where they are surrendered or handed over. In other words, the definition of deliverables relates to distribution. Ask.com answers the question: What are deliverables? (answer)

Distribution networks operate within supply chains. The Internet is an example of both. Its product is information. Its service is the delivery of information. Computers, peripherals, and servers may be referred to as nodes. Sometimes the word is used to describe the connecting point in other chain-like processes. A node is simply a connection.
