1a. An operating system is a software that is creates the tasks that every single computer is able to do, it is the main source of the actions of the computer.
1b. Two utilities that could be used for the user to use the computer despite his injury would be on an on screen keyboard that could be accessed through the mouse and another utility would be voice recognition software. The Onscreen keyboard would allow the user to only have to use one hand to type and It would make everything a lot faster and more efficiently because he would not have to waist his time finding the keys. Voice recognition software would work because the user would not need his arm to talk and as a result everything he says can be put onto the computer and his words can be typed out.
4a. Artificial intelligence is the intelligence of machines and the branch of computer science that aims to create it. AI textbooks define the field as "the study and design of intelligent agents"
b. Clippy could tell that the user is writing a letter because he knows when Microsoft word is being open and he can identify when a header and a footer are being used. Headers and footers are used for letters and as a result Clippy can tell when they are being used and can tell when a letter is being made. Clippy can also narrow down possible intentions of use which shows that he can find out what each word file is being used for. Clippy can tell when letter information is being used when addresses, cities, and zipcodes are being entered into word.
2a. Two technical reasons why the quality of the videos could be limited is because they may be very large files which allows them not to be seen as efficiently and speed is limited which means it takes longer for them to be processed.
2b. There are many possibilities why some web based videos do not play on some computers at all. One possibility is that different standards in existence and different standards require different software, which means each computer has different programs and software, and one could not contain the software needed to play the video, such as Adobe flash player. Another possibility is that a computer has insufficient RAM, which means it would not have the ability to obtain and play the video efficiently. The possibility of different software shows that if a computer did not contain the right software it would not be able to take part in the video watching. Each computer has a different amount of RAM which is very important because without more or less can be watched.
2c.
The increase in sales and tickets could be at an all time high because of the availability of online web-based materials because it makes it easy to look up specific areas of interest that somebody has. Instead of waiting long periods of time or guessing until something they want to see appears, they can find the exact date and go when they want to see what they want; it provides selection and options which people value greatly. Another reason this might be because of web based materials is that there is an increase of exposure to the opera and art galleries because people are subject to the idea of going much more as it can appear in adds on the Internet more rather than people hearing it manually. Another reason web based material could be responsible for the result of availability is that it gives the “try before you buy” mentality and potential that people value because they can tell or see what they are getting into and ultimately what they will be going to. It also provides links to websites that people value and want to go to.
3a. The term text file refers to a type of computer file. Text files are a computer file whose information is expressed in text/writing.
3b. OCR can convert handwriting into text file by scanning the written text, text is digitized, text is stored as a graphic file, letters are stored, size of writing found, pattern matched with stored shapes. This process converts the handwriting into text file step by step and is a complex way to change the OCR into text file. The text goes through this process to change every time that it is changed to a text file.
3c. It may not be accurate using OCR techniques for a multitude of different reasons. However four major reasons why are that the handwriting may be too messy to read, all of the letters may be joined up and difficult to read, there could quite possibly be resolution issues that cause it to be hard to see the image, the writing may be faint and it could be hard to identify what is trying to be sad so as a result the text can not be converted.

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.
