The list of databases that may contain information about me is rather long it might be the bank where I have my credit card serviced, it is the school database, the library database, the database of my favorite computer club and databases of all shops where I have ever done my shopping the information from my credit card is automatically registered in every place I conduct any financial operation, be it buying a ticket to another city or paying for a DVD disk.

Visual and audio databases may be effectively used within a company as they may serve specific needs of handicapped people or may serve the specially planned promotion company of, for instance, a new sound system where it is necessary to assess not the image but the sound, and vice versa. However, the more general use is for people with disabilities.

The free Wi-Fi access is good for people to remain mobile and to be able to gain access to the Internet everywhere. But on the other hand the technologies have to pay off, and in case everyone will get access to them for free there will be no funds for financing further development. More than that, overall access to the Wi-Fi network will pollute and overload it, thus worsening the quality of provided services.

The course seems to be very informative and explicitly built to make up a good distance course. There are a large number of facts, definitions, explanations and visuals that would enhance the overall understanding of the topic. However, the material is rather hard as it concerns many aspects of information systems functioning for this reason in some cases, e.g. explaining the work of software and hardware it is better to perform certain functions in the class but not in a distanced way.
WCP has developed dramatically because of peoples striving for mobility and wider access to the Internet, finding easier, quicker and higher-quality means of communication and data transmission. Despite this, in case the air is overloaded by the users who do this not only for business but mostly for fun, in the nearest future the technologies are likely to make a turn and become focused on finding more advanced and high-quality ways of communication that are not so heavily overloaded, so WCPs production is likely to decrease, unless the way to provide high quality for the ever-increasing number of users is found.
