HP ProDesk 400 G4

A Slim SuperMulti DVD Burner is included for reading and writing to a variety of CD and DVD media, including CD-R, DVD±R, DVD±RW, and more.

The system features four USB 3.0 Type-A ports (two front, two rear) and four USB 2.0 Type-A ports (rear), each of which will allow you to connect peripherals such as hard drives, printers, and memory card readers. At 5 Gb/s, USB 3.0 transfers data up to 10 times faster than USB 2.0, which operates at 480 Mb/s. USB 3.0’s high-speed transfer rate helps to significantly reduce data transfer times, meaning you spend less time waiting and more time focusing on the task at hand

The system uses a Realtek RTL8111HSH Gigabit Ethernet controller for Internet access when connected to a router, modem, or network switch.

For those who wish to connect to the Internet wirelessly, there is an empty M.2 2230 PCIe x1 slot that supports a separately sold Intel 3168 802.11ac 2×2 Wi-Fi and Bluetooth 4.2 Combo Card.

The front headset connector supports CTIA style headsets. Headset connectors are retaskable to function as a line-In, microphone-in, line-out, or headphone-out port. Rear audio input ports are retaskable as a line-in or microphone-in port. External speakers must be powered externally.

Multi-streaming can be enabled in the audio control panel to allow independent audio streams to be sent to/from the separate connectors or internal speakers. This allows for different audio applications to use separate audio ports on the system. For example, the front connector could be used with a headset for a communications application while the rear connector is being used with external speakers and a multimedia application.
