# Configuration NICs

On the NICs configuration, you can add and delete NICs used by the virtual machine on the instance. There are several types of adapters used.

<table><thead><tr><th width="233">Adapter Type</th><th>Information</th></tr></thead><tbody><tr><td><strong>E1000</strong></td><td>This adapter card is used for compatibility and easy installation on various operating systems.</td></tr><tr><td><strong>E1000E</strong></td><td>This adapter card is a development of the E1000 and is used for high network loads.</td></tr><tr><td><strong>SRIOVETHERNETCARD</strong></td><td>This adapter card allows virtual machines on the Instance to increase network performance and reduceoverhead virtualization.</td></tr><tr><td><strong>VMXNET2</strong></td><td>This adapter card is used for high performance and efficiency, especially in throughput dan latency.</td></tr><tr><td><strong>VMXNET3</strong></td><td>This adapter card is used for high performance and supports many features such as parallel networking, network offloading, and high scalability.</td></tr><tr><td><strong>VMXNET3VRDMA</strong></td><td>This adapter card is used to add Remote Direct Memory Access (RDMA) allowing very fast data transfer without burdening the CPU so it is suitable forhigh throughput andlow latency.   </td></tr></tbody></table>
