Answer

Anything larger and the computer would need to break the number into smaller pieces.


 


16-bit is a computer hardware device or software program capable of transferring 16 bits of data at a time.

Q:

What is time-stamping?

Answer

When a message is received, the receiving system 'j' sets its counter Cj to 1 more than the maximum of its current value and the incoming time-stamp Ti. At each site, the ordering of messages is determined by the following rules: For messages x from site i and y from site j, x precedes y if one of the following conditions holds....(a) if Ti
