Some processes require the ability to inform the kernel beforehand, so that once the kernel discovers that one or more of the I/O conditions specified by the process are ready (that is, the input is ready to be read, or the descriptor is able to

(i) Basic knowledge The maximum size of the IPV4 datagram is 65535 (16 bits), including the IPv4 head. IPV6 datagram Maximum size is 65575, including 40 bytes of IPV4 header MTU, which is specified by hardware, such as the Ethernet
