Broadcast traffic is used to send data to all devices on a network segment and does not require prior knowledge of each device's network address. It's essential for tasks such as discovering devices or services within a network segment. ARP requests are a common example where a device needs to map an IP address to a MAC address and sends a broadcast query to all devices in the local network segment, expecting a response from the device owning the address. The other answer choices, 'Communicating between two specific hosts', 'Encrypting data packets in network communications', and 'Speeding up Internet browsing speeds', do not aptly describe broadcast traffic usages. Particularly, specific host communication typically uses unicast, encryption pertains to security not traffic type, and speeding up browsing is unrelated to broadcast functionality.
