Classwork 2/14

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.
