Interconnects can be classified into several categories, including:

1. PCIe (Peripheral Component Interconnect Express): A high-speed interconnect standard used to connect GPUs, CPUs, and other components to the motherboard.
2. InfiniBand: A high-speed interconnect standard used to connect clusters of nodes in a datacenter.
3. NVLink: A high-speed interconnect standard used to connect GPUs and other components in a datacenter.
