Classwork 4/12

1. a) Two tasks performed by a network server apart from the storage of users' files is that the information is stored onto the computer instead of a storage file which would be able to be removed but the files on the computer are stored. Another would be that the information would be able to be deleted or lost more easily because it is not stored on an actual storage unit but inside the computer.
b) One advantage of schools providing their students with USB drives is that they could store a lot more of data and information on the USB drive. One disadvantage of schools providing their students with USB drives is that the students could easily lose their USB drives because of their size.
c) Two precautions that a student should take when using USB drives for saving important work would be that they need to make sure that they do not take out the USB drive to quickly because the information won't save. Also, they need to make sure to save the information to the USB and not anything else.
4. a) i) The software is a database
ii) Another task is to query the information in the database

b) Two other IT methods that can help them to use the application software successfully would be to view a tutorial on how to use the methods that have to be studied. The tutorial would teach the users how to successfully use the application software as it would go over all of the different aspects and capabilities of the software. Another IT method would be using the Internet because the Internet has a variety of different ways and websites that show how to work certain software.

c) It is the responsibility of the company, rather than the employee, to pay for the training because the company is the one who wants these people to train and the employees are only told what to do making it so that the company is the one in charge to pay for the training. The company is obligated to pay because they are the ones that are demanding that the employees get trained and without that training the employers would not have employees that knew how to do the job. It is the responsibility of the employers of the company to properly manage and pay for a system that gives training employees the ability to learn how to use the software.

5. a)
i) A terabyte is a unit of data storage which also stands for one trillion bytes.

ii) GPS stands for Global Positioning System that positions people and objects on certain parts of the planet based on satellites and the frequencies they pick up.

b) The steps involved in capturing and storing the satellite image data that will be used to create the maps in google earth are that the satellites survey each and every given spot of land on the planet, a process that is done over and over again for each single spot of land, the land is surveyed and images are taken of the land as well as its surroundings. The images that are on the satellite are saved and converted to the google server where they are implemented into the google software on google earth.


c) GPS technology and mapping software work together to allow the operator to find a destination by pin pointing separate destinations through satellites and destinations that are on the map. The destination has to be selected or found on the mapping software and picked up by the satellites the GPS uses. The cell phone equipped with GPS has a signal that is picked up and is transmitted that can show the operator where to reach his destination. The network is used to take the coordinates and put in the mapping software. As a result the user is able to find where they want to go and their given path such as LAX. The mapping software uses coordinates to determine location of map and
searches the function that enables a search of the airport.



d) It is acceptable to a very great amount for many particular reasons. The possibilities of having high resolution images are that they can be harmful to the privacy and protection of some places. For example, if the government is trying to hide a military base, and anyone with access to the Internet can see what is going on in the base by google earth, it is not being protected at all. High resolution google images put countries at risk and become vulnerable to other countries with higher technological developments because it then becomes an issue of natural security. The advantages of having high resolution images on google earth however is that it makes it very fun and entertaining to view attractions, homes, and even people that can be seen through the images on the website. It is advantageous because many people use the website for both business purposes such as pinpointing open land as well as entertaining purposes. The disadvantages of having high resolution images are that terrorists or rival countries can keep track of the opposite countries movements and military change over periods of time very accurately and efficiently. An advantage of lower resolution images is that they can be put onto google without any trouble or controversy because they pose no major threat, however they contain disadvantages such as not being able to be seen very well and not being as entertaining or fun because not much can be seen. I believe every google image should be in low resolution to assure the safety an security of each citizen, and not let a website cause havoc among different countries and people.
The lower resolution images prevent breaches in national security where terrorists could locate sensitive military installations and business or individuals may feel more secure if unauthorized people cannot view details. However blurring certain parts of map would cause integrity issues and the “bad guy” would not be able to spot where weapons were located.
