America's new president, Harry S. Truman (1884â1972), made her the American representative to the United Nations Commission on Human Rights.
Window: 16 bits The number of data octets beginning with the one indicated in the acknowledgment field which the sender of this segment is willing to accept. Checksum: 16 bits The checksum field is the 16 bit one's complement of the one's complement sum of all 16 bit words in the header and text. If a segment contains an odd number of header and text octets to be checksummed, the last octet is padded on the right with zeros to form a 16 bit word for checksum purposes.
This meant that the type field in Ethernet could be used for other purposes, if an 802.2 header appeared at the beginning of the user data, so the IEEE standard for Ethernet, IEEE 802.3, included after the source MAC address a 16-bit field indicating the length of the user data in the packet, for the benefit of protocols that couldn't infer the length of the user data from the length of the packet as received.
