# Paravirtual devices
# Paravirtual hardware
*Paravirtual hardware are emulated hardware or devices that can be found in a virtual environment. Contrary to other emulated hardware, they don't intend to mimic a particular piece of real hardware. More details on the [lexicon](/virt/lexicon)*
In this section, the focus is oriented towards Virtual I/O Devices (VIRTIO), also known as the `virtio` family of devices:
* **Graphical frame buffer:**
* [`virtio-gpu`](/virt/virtio/gpu)
* **Video decoding/encoding:**
* [`virtio-video`](/virt/virtio/video)
* **Sound:**
* [`virtio-snd`](/virt/virtio/snd)
* **Block storage:**
* [`virtio-blk`](/virt/virtio/blk)
* [`virtio-scsi`](/virt/virtio/scsi)
## Graphical frame buffer
* [`virtio-gpu`](/virt/virtio/gpu): paravirtual GPU.
* Provides a subset of the host GPU capabilities to a guest virtual machine
## Video decoding/encoding
* [`virtio-video`](/virt/virtio/video): paravirtual video device
* Provides encoding and decoding capabilities to a guest virtual machine
## Sound
* [`virtio-snd`](/virt/virtio/snd)
## Storage
* [`virtio-blk`](/virt/virtio/blk)
* [`virtio-scsi`](/virt/virtio/scsi)
## Network
* [`virtio-net`](/virt/virtio/net)
## Input devices
* [`virtio-kbd`](/virt/virtio/blk)
* [`virtio-`](/virt/virtio/scsi)
