TASK 1: List all the dial-up modem speed (connection vs bitrate)

Note that the values given are maximum values, and actual values may be slower under certain conditions (for example, noisy phone lines)
Connection
110 baud (Bell 101)
0.1 kbit/s
(110 bits per second)
300 baud (Bell 103 or V.21)
0.3 kbit/s
1200 baud (Bell 212A or V.22)
1.2 kbit/s
2400 baud (V.22bis)
2.4 kbit/s
2400 baud (V.26bis)
2.4 kbit/s
4800 baud (V.27ter)
4.8 kbit/s
9600 baud (V.32)
9.6 kbit/s
14.4 kbit/s (V.32bis)
14.4 kbit/s
28.8 kbit/s (V.34)
28.8 kbit/s
33.6 kbit/s (V.34)
33.6 kbit/s
56k kbps (V.90)
56.0/33.6 kbit/s
56k kbps (V.92)
56.0/48.0 kbit/s
Hardware compression (V.92/V.44)
56.0 to 320.0 kbit/s
(variable)
Server-side web compression
   200.0 to 1000.0 kbit/s
(variable)


The figure above shows that the connection with its modulation , bitrate and year released.
