The telephone one of the best.

 The telephone is one of the most used inventions ever invented. It is used world wide connecting people from one side of the world to the other side. They send speech over long distances by using electric currents, laser light or radio waves.

 The telephone was invented in 1876 by a Scottish engineer called Alexander Graham Bell who lived from 1847-1922.  He had been working in the United States on improving the telegraph, which used Morse code which used dotes and dashes to send the messages to other users but it was limited, but so were the early phones. By 1880, the first public telephone system were in use, although they had hardly any subscribers.

 Early telephones were connected by wires to a telephone exchange, where operators would connect the two wires by hand which was very hard when the invention got bigger and more people were using it. The invention of automatic switches in the 1890s allowed the exchanges to connect calls without going though an operator, where there could be problems or mistakes which all lost time. Modern telephone systems change the varying electrical signal of older phones into a digital signal made up of electrical pulses that are handled by computerized exchanges, getting rid of the old fashioned mechanical ones of ...

Here's what a star student thought of this essay

The report states the term '3G', however this isn't explained or defined. All technical terms will need to be described, to allow the examiner to have a clear understanding of the report.

The report states how a telephone works by a person speaking and listening on a device, known as an telephone. This is quite good, as this is quite detailed and gives a good description. The last paragraph, I believe is in-correct. As Alex Bell created the first form of a telephone, however this has been developed and changed drastically, and this doesn't make scene to only credit one person for this. The report could include 'In addition, there are a number of companies which developed this technology, such as Sony, Nokia and Apple.'.

In summary, the report is basic on the areas which are mentioned. However there is a section (mobile phones) which is missing out of the report, and what is written is quite basic and it's clear that the student doesn't fully understand the usage of telephones/mobile phones. The report gives a benefit, but effective description of how telephones can into use and how these were created/developed over time. The report does seem to jump from telephones to mobile phones using fibre-optic lines. I believe that there is quite a large chunk missing off the report, as there haven't included the part of how mobile phones came into use and how these are used.
