Data and Network 2
Answer 1
1.1
Data transfer rate in a second is known as bit rate. It can be measured in such as bps, Mbps, and
others. It is the way to identify a number of bits transfer in the channel. Most of the network is
based on the speed on the channel. In addition, organizations have selected network based on
the bit rate (Tanenbaum, 2014).
1.2
We can calculate the bit rate using this formula, which is s:
Signal per level * bandwidth = bit rate
Therefore, according to provide data,
Bitrate = 8*3 = 24
1.3
We can calculate the channel
C = B log2(1+SNR)
SNRdB = 6 dB
Therefore,
SNR= 10 log10(S/R)  SNR = 4
C = 3*106 x 1og2(1+4) ≈ 8 Mbps.
C= 2 Mbps
1.4
In a network, a channel is used for the data transfer. A channel is used to transfer the data using
a medium. In addition, the channel has used for making a connection between different nodes.
We can provide the actual transfer rate of that medium using data rate. It is a speed of data
transfer in a medium between two workstations (Tanenbaum, 2014).
