| 1. Define Bluetooth. [1 point]
A Bluetooth is a communication tools which uses radio waves in the frequency band to allow Bluetooth enable devices to automatically connect with each other.
2. State what can Bluetooth do on the smart phone in what kind of condition? [2 points]
Bluetooth can transfer data to each other’s smart phone with a condition of the security mode selected for each device.
3. Draw an example of multiple piconets (including piconets A, B, and C) [6 points]
• temporary network
• up to 8 active devices (as of 2010)
• master (m) controls the piconet and the slaves (s)
• each Bluetooth device can act either as a slave or a master in a different piconet
4. Write 4 examples of other communication tools (exclude Bluetooth)
[4 points]
• Wi-Fi
• Mobile Phone (Cell-Phone) Networks
• Infra-Red
• USB
• Ethernet
• WiMAX
• Firewire.
5. Identify two types of memory that are built in mobile devices. [2 points]
1. ROM
2. Cache Memory
3. RAM
4. Flash Memory
6. Explain RAM (including other two names that is also known as RAM). [3 points]
Another two names of RAM are dynamic memory and SDRAM. RAM is the electronics where the OS and all applications actually run.
7. What is the similarities and difference between Bluetooth and Communication? [2 points]
The similarity between Bluetooth is that they are all communication tools, but the difference is the way of communication is different. Communication tools have ability to communicate directly to smart phones, mobile phone or computer. Bluetooth is to communicate with other device by sending data or connecting the data that is in the mobile device.
8. Identify 4 types convergence of technology that is used in the Smart phone. [4 points]
1. Digital camera
2. Mobile Phone
3. Mp3/4 Player
4. Web Browser
5. E-mail Client
6. Palm-Top Computer
7. Direct link with social networks
8. Wireless Credit Card
9. PIM
(Any of this 4 will be correct answer)
9. Identify 4 types of keyboard.
1. Detachable Keyboard
2. Scroll wheel
3. Thumb wheel
4. Multi-touch
10. Explain the difference between original touch screen and modern touch screen. [2 points]
Original touch screen provided a limited number of option, but modern versions provide multi-level menus and the ability to “scroll” though various screens.
11. Describe the touch screen that is used in the iPhone. [4 points]
The iPhone 4 includes a panel laminated on the glass which uses electrical fields to sense the user’s touch. It has a multi-touch feature that can register simultaneous touches. The user can bring up different information or menus by actions such as swiping, tapping and pinching. Information is displayed on the panel using a “Retina display”. This display contains a high pixel density (326 pixels per inch) that provides clear, sharp images.
12. Briefly explain Generation. [2 points]
The communications industry has found it convenient to refer to major advances in mobile phone technology in terms of generations, a generation appearing approximately every 10 years.
13. Define revolution. [1 point]
Revolution means that the new technology is not backwards-compatible, so a new frequency spectrum is needed.
14. Define evolution. [1 point]
Evolution means that the new technology can use the same frequency-bands.
15. Choose one type of generation (1G, 2G, 3G, or 4G) and explain it. [3 points]
1G 1979 • First generation deals with the analog transmission of data.
2G 1991 • Transmission became digital.
• Speed in terms of Kilobits per second.
3G 2001 • Much faster speeds (in terms of Megabytes per second).
• Good for multimedia/video streaming.
• Data sent in packets.
• Simultaneous use of speech and data services.
• New frequency bands, higher data rates and non backwards compatible transmission technology.
• 3G networks offer greater security than their 2G predecessors. By allowing the equipment to authenticate the network it is attached to, the user can be sure the network is the intended one and not an impersonator.
4G 201? • Already plans to bring in 4G with speeds in the Gigabits range.
• All networks will be IP packet-switched.
16. How many years will there be a new generation? Approximately. [1 point]
Approximately 10 years.
17. Explain how smart phone will get attack? [1 points]
Smart phones are as susceptible as normal computers to attacks from outside sources including viruses, phishing and social engineering efforts.
18. List 4 ways to prevent data in the smart phone to loss. [4 points]
• encrypt all data that a smartphone receives
• clear all caches after each VPN (Virtual Private Networks) session
• choose one with a “kill” switch
• password before opening applications such as email, web browser
• keep data permanently in your data centre, not on the smartphone
• some companies can wipe the data off your stolen smartphone remotely
• do not run apps not approved by the phone company
• do not use unsecured Wi-Fi networks (to avoid “man-in-the-middle” attacks)
• do not “jail-break” your smart phone.
19. Explain application. [1 point]
Application allows users to download specific software modules developed by independent companies.
20. One example of smart phone’s effect to the society. [2 points]
Example:
My Mobile Phone
“It’s right by my bed when I go to sleep and right by my bed when I wake-up and it’s like the first thing
I go to,” 15-year-old Sarah Matzkin told CNN.
