Detailed explanation-1: -This is done because the size of a packet is about 1.5KB for Ethernet and 64KB for IP payloads. The Maximum Packet size for TCP is 64KB.
Detailed explanation-2: -The standard size of a TCP packet has a minimum size of 20 bytes, and a maximum of 60 bytes.
Detailed explanation-3: -The minimum size of an IP packet is 21 bytes (20 bytes for the header, and 1 byte of data). The maximum size is 65, 535 bytes. In the capture shown in Figure 2.13, the Total Packet Length is set to 60 bytes. Twenty of those bytes are used by the IP header, meaning that 40 bytes are used for data.
Detailed explanation-4: -3 565 bytes is the length of the first segment of the TCP data packet, which contains the HTTP POST. 1460 bytes is the length of each of the remaining five TCP segments individually.
