Shared communication channel to clients and peers are provided by Orderer peers.

It offers a broadcast service for messages containing transactions. The channel is used by the clients to broadcast the messages which is then delivered to the peers.

The message is communicated with total-order delivery and reliability. The channel outputs the same messages to all connected peers and outputs then to all peers in a logical order. The ordering service's prime aim is to provide ordering of published transactions and cut blocks with ordered transactions.

Orderer is a node running the communication service that implements a delivery guarantee, such as atomic or total order broadcast.

Orderer peers are responsible to create channels and provide means to share messages among other peers.

You can consider the orderer peer to be like the admin of a team. The orderer peer creates the blocks and provides it to other peers in the network. After this, the endorser peer and the anchor peer do their job.
