Aseven-octet pattern of alternating 0s and 1s used by the receiver to establish bit synchronization is a select one:
a. source address
b. start frame delimiter
c. preamble
d. destination address

Using a conditional expression, write a statement that increments numusers if updatedirection is 1, otherwise decrements numusers. ex: if numusers is 8 and updatedirection is 1, numusers becomes 9; if updatedirection is 0, numusers becomes 7.
