How wi-fi and the Internet may be used by a business.

Extracts from this document...


Wi-Fi Wi-Fi is a wireless connection to the internet, sometimes called 802.11. The wireless network works by using radio waves to send and receive signals between the devices using the wireless connection and the internet router. Once the router receives the signals from the devices it decodes the information and sends it to the internet through a physical, wired, connection. This process also works in the reverse order, as the router can receive information directly from the internet and then will send it to the wireless devices that are connected through the radio waves. This will then output the information onto the devices screen. Below is a diagram of a set up Wi-Fi connection: Advantages An advantage of using a Wi-Fi connection is that it is wireless, so that the device can be mobile and still be connected to the internet, as long as it is within the radio waves radius of the router. Wifi is able to transmit any type of data via the radio waves, as long as the device receiving the data is compatible with it. Another advantage of using a Wi-Fi connection over a wired connection is that more than one device can easily connect to the connection via the router. Also this allows different types of devices to be connected to the network. Such as a mobile phone, this cannot be connected via a wired connection like a pc. ...read more.


Advantages A big advantage of using the internet is that most forms of communication can be done through it. In fact a lot of forms of communication require the internet, such as WWW based information, or e-mail. Another advantage of using the internet is that a lot of information can be found. The easiest and fastest way to find something on the internet is through using a search engine, such as Google. The final advantage of using the internet is that it is all one big network. This means that information from all over the world can be found out from just staying in one location whilst on the internet. There is so much information on the internet that can help with most problems, which is usually simple to find. Disadvantages A disadvantage of using the internet is hackers. Hackers can hack into computer systems through this network if the correct security software isn't being used. This means that hackers can view the content of many computers that are unprepared. Another disadvantage is that the internet costs money. The more money that is paid for an internet connection the better internet connection it should be. There are several different types of internet connection, one being ADSL and another being ISDN. An ADSL (Asymmetric Digital Subscriber Line) offers the faster connection, however it only offers a standard of one connection. This is unlike an ISDN (Integrated Services Digital Network) ...read more.


This would enable the owner of Chello Hotel to be able to read this report without having to have knowledge of each technology before hand. The second good factor about this report is that images are used to illustrate each technology. This is good because it means that each image is used to recognise what the technologies look like. The third good point is that this report sticks to the house style of all of the Chello Hotel documents. Even though this document is not going to be shown publicly by the hotel using the house styles still makes it more official to the hotel and more professional. The final good point about this report is that the layout is consistent throughout. It is all fully justified, size 12, black font, apart from the headings. This is good as it sticks to the original hand drawn plan What are the bad things about the report?/further improvements that could be made One bad point about this report is that it is very long. This could be improved by using more bullet points instead of full sentences to get across the same points. If this method of more bullet points was used not as much detailed information would be able to be within the report. The final bad point about the report is that not all of the images used are not in great detail. Some of the images, however, are in much detail and explain a lot about the technology. This criticism could be improved by using more diagrams of the technologies rather than photographs of them. ...read more.
