This is impossible all Web Browsers display things differently and do not support some codes or interpret some codes differently from others but for the most part they all interpret your codes very similar
Every Theme allows a specific size of header. Check your theme's code.
in tcp header (32 bits) we have a field that is called options and padding that has variable in length and the header length shows the actual header size i.e size of 20 octets+size of options and padding field and in UDP we dont have any field like that and its header is fixed of 8 OCTETS (32 bits header size) refrence: WIRELESS COMMUNICATIONS AND NETWORKS by William Stallings Second Edition pg 91(see fig)
no
Header is always a multiple of 4bytes and so we can have a maximum length of the field as 15, so maximum size of the header is 60 bytes out of which 20 bytes are mandatory.
h6
maximum size is 512 bytes without header
20 bytes, without options
That would depend on the size of the Logo and what it represents.
8
160 bits (20 bytes)
In C programming, header files are required. It doesn't matter if you are using near pointers, far pointers, both, or neither -- you still need header files. There is no connection between the necessity of header files and the pointers' size.
The datagram length field in an IP header is 16 bits in length. Therefore, the maximum datagram size an IP datagram can support is 2^16 - 1 = 65,535 bytes
