A chip is a small piece of semiconducting material on which __ are etched. network nodes integrated circuits IP addresses encryption codes

## Step 1
The problem is asking us to identify what is etched onto a chip. A chip, in the context of computer science, is a small piece of semiconducting material on which integrated circuits are etched.

## Step 2
Integrated circuits are a series of electronic components such as transistors, resistors, and capacitors that are etched onto a chip. These components are the building blocks of a chip.

## Step 3
Network nodes, IP addresses, and encryption codes are not etched onto a chip. They are software elements that are implemented by the hardware, which includes the chips.
