What would be the benefit of setting up 2 desktop computers as a network at home?

Question by Little Momma to a 1 year old: What would be the benefit of setting up 2 desktop computers as a network at home?
I will be purchasing 1 and I have one my daughter will be using. I asked a question yesterday about getting a new computer and someone suggested making the 2 computers a network. What exactly does that mean and is there any benefit from it?
