Explanation:
Binary representation of 12 = 00001100
Expressing it in hexadecimal format : 0C
Binary representation of -12:
Step 1 : Computing 1's complement for 12 =11110011
Step 2 : Adding 1 to 1's complement to get the 2's complement =>
11110011+1 = 11110100
Converting the 2's complement representation to hexadecimal format:
F4 ( 8 bit representation) or FFF4 ( 16 bit representation)

DSL(Digital Subscriber Line) :-It is a technology in which user gets high bandwidth connection over ordinary telephone lines.
This technique uses data modulation to achieve higher throughput over the telephone lines.Telephone lines carry voice signals over a small range of frequencies between 300 and 3300 Hz. So the frequencies that are higher are unused and available for data transfer.
DSL connection uses a modulation technique based on amplitude or phase modulation. With the help of modulation techniques DSL uses these unused higher frequencies.It uses frequency range higher than 300 to 3300 hz.
