Why is the network the most important IT infrastructure component?

Why is the network the most important IT infrastructure component? 

Imagine walking into a big city for the first time. It's filled with buildings (hardware), people (software), and roads (network) that connect everything. But what's the most important IT infrastructure component? It’s the network - the roads. They hold everything together.

In the world of IT infrastructure, it’s the same. Think of it like this: the network is like the streets of the city, linking everything and everyone. It makes sure that messages (data) can move smoothly from one place to another. It connects all the parts of IT – hardware, software, and more – allowing them to work together as a team.

Without good roads (network), even the nicest buildings (hardware) and people (software) can’t work together properly. So, when you think about IT infrastructure, remember to focus on the network. Make sure it's strong and reliable, helping every part of the IT city to be its best!
