Networking Class - Analog and Digital Comparison Paper Essay

Networking Class - Analog and Digital Comparison Paper - Essay Example Some technology experts are of the view that technology is becoming more difficult to define. Technology involves so much today and the processes and activities included keep on increasing as technology changes (Buchanan, 2013). There are various forms of technology, of which the most common are analog and digital forms. Analog technology is process of recording data linearly from on-point to another which digital technology is the process of recording data using the binary system, which includes zeros and ones, and storing the data in digital devices. The variations in the two forms create a number of benefits and disadvantages of each form. Analog technology is relatively easy to produce and data is well represented. However, it is difficult to transmit and receive data, there are a lot of interruptions especially noise, and analog devices are relatively expensive and data is not accurate. There are various forms of analog technology; Amplitude Modulation (AM), frequency modulation (FM), phase modulation (PM) and Quardrature Amplitude Modulation (QAM) (Sharma, Mishra, & Rajiv, 2010). Amplitude modulation is a technique in which the strength of the signal sent is changed or varied depending on the information being sent. AM bounces of the atmosphere and when conditions are optimal, it can be received across the world. However, this technique is usually affected by noise making it not clear. Frequency modulation is a technique in which the frequency of the signal being sent is modulated or changed depending on the information being sent. FM can broadcast a number of channels on the same signal. This technique is limited to certain regions and areas and cannot be used out of the boundaries of that region. Phase modulation is a technique in which the phase angle of the information sent is changed to the proportion of the message sent. This technique is much simpler compared to the rest. However, it needs a
