Question

Which is the device which filters and forwards the data packets over a network.

Answer 1

The device which filters and forwards data packets over a network, is known as a Bridge.

It filters and forwards data packets by physical address, operating at the Network Access Layer (NAL) in the Transmission Control Protocol (TCP) or IP protocol stack. Data is sent in manageable chunks called packets. Data packets travel through Application Layer, on to the Transmission Control Protocol.
