The Diskless PC Revolution

Discussion Questions
1) Using a flashdrive can be helpful, becasue it is more convenient than carrying around a personal computer, and one can transfer files form other computers into it easily. Also, you dont have to worry about losing information if your PC isn't working properly, or if the memory is malfunctioning, our data is always with us. The downside is that becasue it is so small, it can be easily lost, and one risks losing all their important files.

2) It would be more secure becasue you would have your informaton with you an a flashdrive, it wouldnt be cnnected to a server so no one could steal it and it would be less likey lost becaue you would always have it on your flashdrive, and wouldnt have to rely on computer memory.

7) Non-Impact printers can print many pages quilkly with high quality. they are very durable and reliable. The disadvantages are tht they are more pricey and cant be used to print multipart forms.

8)These peripherals can be used to enter information into the computer, as well as display the output. An example can be memory devices, that can give information to the computer, as well as save/extract information from it. Touch screens are also a good example because they can be used to input commands, and display output at the same time.

9) Sequential Access Memory has a lot of space to hold information, however, it takes time to access information . It is usually used as a back-up memory. Random Access memory can retrieve information very quickly but cannot be used to store large amounts of information.

Biometrics

1- Define biometrics

A method of identifying individuals based on biological properties; The technology must scan the body part and compare and try to match the information to data previously stored in the database.



2- list and explain a use of a biometrics system in each area of impact



a) Business and Empoyment: Banks would use iris scanning technology so that only employees can access financial accounts and the office. Retailers also allow customers to pay for thie items using fingerprint scanners.

c) Health: DNA recognition can be used to tell individuals apart based on DNA samples.

d) Arts, Entertainment, and Leisure: Regarding travel, airports will be using iris scanners when checking in [eople for flights.

e) Science and Enviroment

f) Politics and Government: Law enforcement uses DNA recognition to accurately find and identify criminals.



3- Explain how one type of biometric system works.

Iris recognition scans the iris and compares the scan to a database of iris patterns to math up the iris scan to data connected to it. FIngerprint scans work in the sane manner, the finger is scanned and the image is compared to other fingerprints in the database to math the print with data.



4- who approves/disapproves of the use of biometrics?



Companies and organizations concerned about security think biometric systems would be most secure and accurate and wish to adopt them in their systems. It is also effiecnet when it comes to certian processes and accurate in identifying people. COnsumers, howver, are suspicious that the government and any company using biometrics willa buse the information they are given from it



5- explain 3 concerns regarding the use of the biometrics system.



a) Security: corporations may abuse biometrics and use the information for personal needs.

b) Crime: People who want to access things that involve biometric security may startt o steal body parts and such to access the area.





6- explain 3 advantages to using the biometrics system.

a)Security: It can keep restricted offices and areas open to authorized personel only, so that others can't enter easily.

b) Accuracy: It is easier to identify people, because biological properties are unique to every individual, they can't be changed or forged in any way.

c) Less Chance of misidentification or identity theft: People's identities would be more secure.

Qwerty keyboard Social/Ethical Questions

Social Questions:
2) How did this issue emerge?
Many, including Parkinson were frustrated with the illogic of the QWERTY keyboard, because it makes i difficult to type efficiently.

3) Who are the stakeholders?
Stakeholders include Parkinson, the designer of a new alphabetically arranged keyboard, and any other who are interested in using/purchasing his new model because they are also frustrated with he QWERTY keyboard.

4)What are the Advantages and Disadvantages for the stakeholders?
The advantage is that those who want an easier to use keyboard that doesn't run on the QWERTY system, can now purchase one. The disadvantage is that because the QWERTY keyboard is so widespread, they'll still have to use it in other places and may not be in practice if they have the alphabetically arranged keyboard at home.

6)What areas of impact does it affect?
This affects business and employment because if the new keyboard become popular enough, many manufacturers will start to produce it and those still selling the QWERTY keyboard may have lower sales. it can also affect any other area because computers and keyboards play a role in all of them, and the people involved in these areas may switch to the new keyboard.


Ethical Questions
8) What are some ethical issues?
Although this new keyboard is being designed to help others it may harm them because if the new design doesn't become popular, those with it will still have to use QWERTY keyboards in other places and they may be out of practice.

9)Who is Responsible?
Parkinson and any who chooses to manufacture and sell the keyboard is responsible for its affects.

10)Who is Accountable?
Parkinson and any company who chooses to sell and manufacture the keyboard, as well as anyone who decides to purchase and use it.

12) Are there alternative solutions?
Those who aren't used to the QWERTY keyboard should simply practice more and get a hold of it. On the other hand if the keyboard is adopted then it should become the new standard used everywhere, or at least available in public libraries and internet cafes.

Review Questions pg 97

CRTs and LCDs

5) CRT moniters are less expensive than LCDS, and they also produce high-quality images at many different resolutions, as compared to a LCD.

6) Laptop computers and video projectors use LCDs to project output becasue they are more compact and easy to carry around. CRTs are too bulky/heavy and cannot project for large viewing audiences, making it unfavorable for these devices.
