In sinusoidal functions or in waves, "phase" has two different, but closely related, meanings. One is the initial angle of a sinusoidal function at its origin and is sometimes called phase offset or phase difference. Another usage is the fraction of the wave cycle that has elapsed relative to the origin.
Hexadecimal numbers are just a convenient representation of binary data. When entered as text, they consist of ASCII characters 0-9 and a-f. The numbers will then have to be converted to binary. This is accomplished by converting to uppercase, subtracting the ASCII offset (48 for 0-9 or 55 for A-F), so that the result is a number between 0 and 15 (inclusive). This can be stored in computer memory to represent 4 bits.
Hexadecimal numbers represent binary numbers in the following way:
hex | binary
0 = 0000
1 = 0001
2 = 0010
3 = 0011
4 = 0100
5 = 0101
6 = 0110
7 = 0111
8 = 1000
9 = 1001
a = 1010
b = 1011
c = 1100
d = 1101
e = 1110
f = 1111
As you can see, no other 4 bit combination exists.
The configuration procedure moves into its final stage once the DHCP server has received the DHCPREQUEST message from the client. An acknowledgement packet, or DHCPACK, is sent to the client at this step.
<h3>What final step of the DHCP discovery process?</h3>
After selecting the proper IP address, the server sends the client an OFFER packet, and the client replies with a REQUEST packet. The process ends with the server sending an ACK packet to confirm that the client has received an IP address.
Therefore, DHCP may dynamically issue IP addresses to any Internet-connected device, node, or client computer.
