b) clippy tells the user how to right a letter by recalling information previously programed into his program which is recalled through the user typing in keywords that would lead to the recalled information; keywords such as "letter" or "how to write a letter"
2. a) two technical reasons why the quality of videos viewed from web sites can be limited are resolution, becuae the low it is the lower the quality of the video and the amount of bandwidth being filled, for if the bandwidth is filled with other information it will pause the video because it needs to buffer
b) Two reason why some web based videos do not play at all on a home computer is because the video is too long. Another reason is because the video is not produced enough so the video can not play.
c) There may be a great amount of audiences for opera, ballet, and plays because the web is does not have the same web-based materials as the real picture does in real life. A person can listen to plays and operas online but it is hard to get the real experience out of them.

3. a) is a kind of computer file that is structured as a sequence of lines. A text file exists within a computer file system.
b) A OCR can convert handwriting to a text file through the computer file. The OCR can convert the handwriting and plates to text files which then can be edited as if they had been typed. The software can sort numbers which then can be read. The information needs to be scanned in order to get onto the computer.
c) The conversion process may not be accurate using OCR techniques because when being converted the files may be confused due to inacurate information, for example if there are scratches or discoloration. The conversion process may be inaccurate using OCR as well if there is a lower case l, L, and a 1, one.

1. a) Two tasks performed by a network server apart from the storage of users' files is gives information to all of the other computers in the company. Also, a network server can send and receive emails.
b) One advantage of schools providing their students with USB drives is that they know the students have the right amount of storage. A disadvantage is that if a student loses the usb the school will have to replace them.
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 should make sure not to break the USB.
4. a) i) The software that has provided this wizard is database
ii) one other task that may be performed by this wizard is query’s
b) Two other IT methods that can help them to use the application software successfully are going onto the internet and looking up a tutorial to help them understand. Also, databases.
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. If, for an instance, employees want to learn additional skills to improve their work and potentially earn a raise the company should not pay for this.

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 camera needs to be involved in order to take the picture. Then all of the pictures must be uploaded to the software and then shared.
c) GPS technology and mapping software work together to allow the operator to find the way to a destination, by working together like on a mobile phone by have the information installed into the phone. The phone will need internet service of course but the satellite can pick up the phone signal and that is how they work together.
d) To a great extent is this decision to alter the maps at users' requests acceptable because people may feel uncomfortable with their houses on the internet and on other peoples phones. This is an issue of security for them because viewing houses is acceptable. If the decision to alter the maps at users requests becomes acceptable this would allow more people to use google maps because they will feel comfortable. Also, this may be a disadvantage because people will see blurred out thing and not know the actual directions.

Some information would be credit card number, license, contact information to make sure that this person is in possession of the bike that they are renting. When they give all of the information they are then given a PIN number to secure that the bike they had rented was theres and not another person.
c) When a bike is rented, information about the bike and cyclist are sent to the central database, With reference to the diagram below, explain the benefits of using a relational database instead of a flate-file database.
The benefits of using a relational database is to stay more organized, which would allow you to place information into every catagory, i.e. bikes, rentals and cyclists, and to make records easy to access, meaning that oone can view the database at anytime with comprehensibly categories.
d) Discuss the privacy and security concerns that could arise through the use of a database to record bike rentals.
The privacy and security concerns that could arise through the use of a database to record bike rentals through alot of possibilities. Some possibilities for security concerns are loss of pin card, theft of the card, and if the customer were to show up with out their card. Some privacy concerns are the fact if the thieve were to claim the identity of the actual customer. When listing the concerns of both security and privacy, security seems to put weigh privacy, because the possibilities to loose the card and in turn the customer's entire access to their account at the business. The biggest privacy concerns were pin card theft because the pin card has all of the customers information on it that is vital to their security.

Politics and government
a) intellectual property is when someone claims ownership to and idea or theory that they invented.
b) Two services that an ISP provides the service of lease server space for smaller businesses and host other people servers, which allows then a separate server for custom uses, and to provide cable and internet to a house hold, i.e. version fios
C) Two ways a home computer network could be adversely affected by the use of file sharing services is that the network is not secure. This means that the home computer network does not have a safe password. Another way which home computer network could be adversely affected by the use of file sharing services is that the website that the file sharing is going on in, example sending emails, posting on social networking sites, are not secure and this information could easily be broken into because it is not secured. There are viruses as well and the quality is not as great.
D) If the government starts to regulate the use of P2P sites for file sharing this would have a great effect on the music industry. For one, jobs in the music industry could decrease because the government would have control on file sharing because music would not be bought. Another possible implication would be that some people would start to download music for free instead of file sharing, which is illegal, but they have no other options. If the government starts to regulate P2P file sharing that would mean that people would not be able to download music meaning that the music industry would get more money. If the government regulates the use of P2P files being shares this would help the music industry get more money.
