The 10BASE2 architecture uses a thin coaxial cable as the transmission medium with a transfer rate of only 10Mbps. The 10Mbps or 100Mbps mentioned here refers to the maximum transfer rate on the NIC, not the actual transfer speed on the network.

The Get_free_pages function can allocate up to a few m bytes of memory, but for a larger number of requests. Even requests that are far less than 128KB generally fail because the system mem
function allocates a DMA buffer and lets the hardware transfer the data to this buffer, and the process is in a sleep state
The hardware writes data to the DMA buffer, and when the write is complete, an interrupt is generated
The interrupt handler obtains the input data, answers the interrupt, and wakes up the process, which can now read the data
Hardware asynchronously passes data to the system
