Single-layer feedforward network
There are many different kinds of neural networks. From witch only a few will be described here. One of them is called single-layer feedforward network. Though, we will briefly explain some things about the different kinds of networks.

Multilayer-network
A network as this doesn't contain any neurons that are connected to themselves or any others earlier in the system. This makes it easy to train, but there are certain limitations - it cannot acomplish any given asignment. Minsky and Papert discovered the so called XOR-problem which was impossible to solve without another layer of neurons. The solution to this was multilayer-network Which has two or more layers.

To describe the inner workings of an MLP we have applied a flash animation.
