@Mammmood - I have a home computer network and I love it. It’s almost like a smart house.
I was amazed at how easy it was to put together, too. If you want to build a home network and you’ve never built one before, start by taking a look at a network diagram example online. You can find these diagrams everywhere and they are high level enough that anyone – even a total beginner – will understand the basic idea of how to put them together.
If you’re not that tech savvy, just print out the diagram and take it to the computer shop. Tell them what you want to do, and they’ll see that they get you the right devices, cables and stuff to get it going. They may even offer to come and help you set it up (for a fee, of course), but I don’t think it’s all that hard. If you can connect cables, you can set up a home network.
