Discussion Questions: 12/30

1. The pros of using a USB versus carrying your laptop is obviously the portability of carrying a small device that can fit in your pocket and would be easier to carry to school then carrying your heavy laptop to school. The cons is that you might loose the USB since its so small so a laptop wont be hard too loose and you can probably save more work onto your laptop then your USB.

2.) Your personal data is private so it is best if you kept it in a USB so your information and privacy cannot be easily shared if it was on a networking server which can be seen by other users on the web.

Researching the Biometric System: 12/29

1. Define biometrics
Measurements of individual body characteristics, such as a voiceprint or fingerprint; sometimes used in computer security.

2.list and explain a use of a biometrics system in each area of impact
a) Business and Employment: Banks would use IRIS scanning technology so that only employees can access financial accounts. Retailers also allow customers to pay for their items using fingerprint scanners for example in Walt Disney World in Orlando they would scan the visitors fingerprints before entering the theme park.

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

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

d) Politics and Government: Law enforcement uses DNA recognition to accurately find and identify criminals of a crime scene.

3.Explain how one type of biometric system works.

IRIS recognition scans the iris and compares the scanning 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 and think biometric systems would be most secure by adopting them in their systems. It is also efficient when it comes to certain processes and accurate in identifying people.

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 start o steal body parts and such to access the area.

6.explain 3 advantages to using the biometrics system.

a) Security: It keeps restricted areas open to authorized people only, so that others can't.

b) Accuracy:It's easier to recognize people.

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

7.what is the benefit of using biometrics as shown in the last clip?

It can be used by advertisers to recognize the consumer it can help advertising agencies and businesses sell their products.

Review Q's:

7.)Nonimpact printers such as laser and ink-jet printers are quiet and provide high-quality output when compared to impact printers. Nonimpact printers, however, are not appropriate for use with multipart forms.


8.)Modems both send and receive information and are, therefore, both input and output devices. Touch screens provide another example. Users provide input by touching the screen and the screen displays information to the user, providing output.

9.)Random access means that any location on the media may be accessed at any time. RAM, hard disks, various diskettes, magneto-optical cartridges, and CD-ROMs are examples. Information stored on media such as tapes may only be accessed sequentially.Tapes are often used for making backups of data and are often considered more secure than many types of diskettes and cartridges.

Reading Review: 12/23

Input:-

1.) The Keyboard: most familiar input devices designed to make it easy to enter data and commands into the computer

2.) The Mouse: To move a pointer around the screen and point to objects

3.) Scanners: Creates a digital image of the page that it can store in memory

4.) touchpad: The user moves the pointer by dragging a finger across the pad.

5.) touch screen: Responds when the user points to or touches different screen regions.

Output:-

1.) Monitor- serves as a one-way window between the computer user and the machine

2.) Printer- produces a hard copy on paper of any information that can be displayed on the computer's screen.

3.) Fax machines- transmits info. stored on paper

2.) Touch screens are sometimes used in information kiosks.

Bar code readers are used to scan bar codes on products.

Magnetic strip readers are used to read information encoded on credit cards.

3.) The trackball, the touchpad, and the trackpoint are all devices that provide suitable alternatives to the mouse on laptop computers.

Criterion H

2 possible IT Solution: create an electronic flier by using a specific program or a software or to create a video (both of these IT solutions would be posted onto the social networking site (Facebook).

Advantages to the creating the electronic flier: is that a picture layout posted on the web will grasp my audiences attention with BIG Words and color layout and would take time to read the flier and would want to attend the event.

Disadvantage: The posting of the flier to the web site may not be able to be viewed (technical difficulties) and also maybe the facebook users would not be on their profile the day of the flier that is posted.

Advantage of the video- in a way of a "commercial" set up may grab the audiences attention
Disadvantage- the video itself well take some time.

The IT solutions will solve the problem of announcements around school and students well want to attend the events or be aware of an upcoming event in the school.

Criterion G: 12/22

For my project I want to be able to convey upcoming events related to school activities that it will motivate students in attending these events. My main target is to create an electronic announcement posted on the web were everybody is able to see. Since one of the main problems in creating posters and flyers and passing it around the school does not help and no one will notice the upcoming events, which is the problem at school. The flyer that i will post on the web would be on one of the social websites like Facebook since many students at Al-Arqam and teachers have an account which will make it easier to grab my audience in conveying the upcoming event. The events would be mostly related to sports tournament. For my IT solution an approaching to this problem I o create my flyer to a hardware or a software like photoshop to publish this document onto the website. Mainly the upper grades (6th-12th) would have better access in seeing the announcement, which then the news will be spreded around the school. Another possible IT solution that may work is to create a video like a short commercial related to the event that it may also grab the audiences attention even better.

3.) If the input 123.4 is read as a number, this means that the decimal representation of the number 123.4 is translated by the computer into its binary equivalent (a series of 1s and 0s). If the input 123.4 is instead read as a set of ASCII codes, this means the computer is treating each character (1, 2, 3, ., and 4) as a literal character. Each of these characters has an ASCII code (a number between 0 and 127). Each code is then translated by the computer into its binary equivalent.

4.) At their core, computers are just a series of switches that have two positions, on and off. Therefore, the binary system of 1s and 0s allows computers to represent rich information from our world using its switches, where 1 is on and 0 is off.

5.) Software is written to run properly on a particular operating system and processor. So software written to run on a Pentium II chip won't work on a PowerPC-based computer like a Macintosh unless a "platform independent" programming language like Java is use

6.) In addition to clock speed (MHz), the architecture of the processor and of the entire computer also determines speed.

7.) Since the mother board is the "heart" of the computer and everything is depended on the external and internal devices have to work together in order to run the hard drive smoothly.

8.) Symmetric Multiprocessing involves a multiprocessor computer architecture where two or more identical processors can connect to a single shared main memory. Most common multiprocessor systems today use an SMP architecture.

9.) RAM (Random Access Memory) provides the computer a place to store information until the processor is ready for it. So the computer can both write to and read from RAM. ROM (Read Only Memory) provides important information to the processor, but this information is stored permanently and cannot be changed.

10.) Primary storage is used to temporarily store information that must be instantly accessible by the processor. Secondary storage is used for long-term storage of information.
