Assignment B

Case Detail: 

Since the rate at which information is transmitted over a channel varies, communicating computer devices must be capable of transmitting and receiving data at differing rates. Data rates are measured in bits per second or bps. Each type of channel has a maximum rate at which data can be transmitted, based on the type of media used in the channel and its design. Generally, channels with data rates less than 300 bps are referred to as narrowband. Rates of 300 to 9,600 bps are known as voiceband or voice-grade. The fastest channels are referred to as wideband or broadband. They are considered to be high-speed channels and can carry data at rates in the hundreds of thousands or even millions of bits-per-second. These high-speed channels require the use of special coaxial or fiber-optic cables.

Data flow can be managed in one of three modes - simplex, half-duplex, or full-duplex. These three modes refer to the direction of the data flow. If you are using a communications system in the simplex mode, data can only travel through the channel in one direction. Since this mode restricts communication to a one-way transmission, either sending or receiving, it is not used very often for communications between two computers. Using the half-duplex mode, on the other hand, data can be sent in both directions, but not at the same time. Using the full-duplex mode, data can be transmitted in both directions at the same time. Systems with special types of wiring may be able to transmit data at higher speeds using the full-duplex mode. However, the half-duplex mode is more commonly used when transmitting data between two computers.



1.         Explain with example that full duplex is better than half duplex communication

2.         How can you say that fibre optical cables are better than other physical media? Explain with real life examples.

3.         Describe the networking scenario where wireless communication is better than other communication mode. Justify your answer also.
