Electrical – the purpose of a resistor network


I ran across a resistor network component, but I can't find any basic electronics tutorials that use these in practice. What is something like this used for?

Imagine you have an IC (microcontroller, shift register etc.) with 10 outputs, each one requiring an additional pull-up or pull-down registers. Or image you have 10 LEDs that need to be conntected to Vcc or ground via a resister.

In such cases the resister network comes in handy. You only need to use one or two resistor networks instead of 10 individual resistors. It's helpful on a breadboard to reduce the number of wires. And it's helpful on a production board as it reduced the number of components that need to be placed.
