Questions and Answers

1.

In Bluetooth, the _____layer is roughly equivalent to the MAC sublayer in LANs.
- A.
  
  1) radio
- B.
  
  2) baseband
- C.
  
  3) L2CAP
- D.
  
  4) none of the above
- E.
  
  5) None of these
Correct Answer
B. 2) baseband

Explanation
The correct answer is 2) baseband. The baseband layer in Bluetooth is responsible for managing the physical layer of the Bluetooth protocol, including radio frequency communication and modulation. It is similar to the MAC sublayer in LANs, which handles the medium access control and data link layer functions.

2.

In Bluetooth, multiple ________ form a network called a _________.
- A.
  
  1) scatternet; piconets
- B.
  
  2) piconets: scatternet
- C.
  
  3) piconets: bluenet
- D.
  
  4) bluenet; scatternet
- E.
  
  5) None of these
Correct Answer
B. 2) piconets: scatternet

Explanation
Bluetooth devices form a network called a piconet. Within a piconet, one device acts as the master and the other devices act as slaves. Multiple piconets can be interconnected to form a larger network called a scatternet. Therefore, the correct answer is "piconets: scatternet".

3.

A Bluetooth network consists of _____ primary device(s) and up to ____ secondary devices.
- A.
  
  1) one; five
- B.
  
  2) five; three
- C.
  
  3) two; six
- D.
  
  4) one; seven
- E.
  
  5) None of these
Correct Answer
D. 4) one; seven

Explanation
A Bluetooth network consists of one primary device and up to seven secondary devices. The primary device acts as the central controller and can connect to multiple secondary devices simultaneously. The secondary devices can only connect to the primary device and cannot establish connections with other secondary devices. This allows for a flexible and versatile network setup, supporting various devices and applications.

4.

The RTS and CTS frames in CSMA/CA ____ solve the hidden station problem. The RTS and CTS frames in CSMA/CA ____ solve the exposed station problem.
- A.
  
  1) can; cannot
- B.
  
  2) cannot; can
- C.
  
  3) can; can
- D.
  
  4) cannot; cannot
- E.
  
  5) None of these
Correct Answer
A. 1) can; cannot

Explanation
The RTS (Request to Send) and CTS (Clear to Send) frames in CSMA/CA (Carrier Sense Multiple Access with Collision Avoidance) can solve the hidden station problem. This is because the RTS frame is used by a station to request permission to send data, and the CTS frame is used by the receiving station to grant permission. By using these frames, stations can coordinate their transmissions and avoid collisions caused by hidden stations. However, the RTS and CTS frames in CSMA/CA cannot solve the exposed station problem, where a station refrains from transmitting even though it could do so without causing a collision.

5.

In Bluetooth, the _______ layer is roughly equivalent to the physical layer of the Internet model.
- A.
  
  1) radio
- B.
  
  2) baseband
- C.
  
  3) L2CAP
- D.
  
  4) all of above
- E.
  
  5) None of these
Correct Answer
A. 1) radio

Explanation
The correct answer is "1) radio". In Bluetooth, the radio layer is responsible for transmitting and receiving data over the airwaves, which is similar to the physical layer in the Internet model. It handles the modulation, encoding, and decoding of the data signals. The baseband layer, on the other hand, is responsible for managing the physical connections and controlling the timing of data transmission. L2CAP (Logical Link Control and Adaptation Protocol) is a higher-level protocol that provides multiplexing and segmentation of data packets. Therefore, the radio layer is the most suitable equivalent to the physical layer in the Internet model.

Rate this question:
6.

Which organizational layer is responsible for developing the goals and strategies as outlined by the top-most level of management?
- A.
  
  1) Tactical management
- B.
  
  2) Strategic management
- C.
  
  3) Operational management
- D.
  
  4) Nonmanagement employees
- E.
  
  5) None of these
Correct Answer
B. 2) Strategic management

Explanation
Strategic management is responsible for developing the goals and strategies as outlined by the top-most level of management. This involves making decisions that will shape the overall direction of the organization and aligning the goals and strategies with its mission and vision. Tactical management, on the other hand, is responsible for implementing the strategies and plans developed by strategic management. Operational management focuses on the day-to-day operations and ensuring that tasks are carried out efficiently. Nonmanagement employees do not have the authority to develop goals and strategies at the organizational level.

Which of the following is collective information about customers, competitors, business partners, competitive environments, and internal operations?
- A.
  
  1) Aggregate Data
- B.
  
  2) External Knowledge
- C.
  
  3) Business Intelligence (BI)
- D.
  
  4) Information Granularity
- E.
  
  5) None of these
Correct Answer
C. 3) Business Intelligence (BI)

Explanation
Business Intelligence (BI) refers to the collective information about customers, competitors, business partners, competitive environments, and internal operations. It involves gathering and analyzing data from various sources to provide insights and support decision-making processes. BI helps organizations gain a better understanding of their market, identify trends, and make strategic business decisions. Aggregate data refers to the combination of individual data points into a summary or statistical format. External knowledge refers to information obtained from external sources. Information granularity refers to the level of detail or specificity of data.

- C.
  
  3) Dirty information
- D.
  
  4) Scrubbed data
- E.
  
  5) None of these
Correct Answer
A. 1) GIGO

Explanation
A technology-literate knowledge worker is someone who has the necessary skills and knowledge to effectively use technology in their work. They understand how and when to apply technology to enhance their productivity and achieve their goals. This type of worker is not limited to a specific field or profession, but rather encompasses individuals in various industries who have a solid understanding of technology and its applications.

D. 4) Systems software

Explanation
Systems software is responsible for coordinating the interaction of technology devices. It includes operating systems, device drivers, and firmware. Operating systems manage the hardware and software resources of a computer system, allowing different devices to communicate and work together. Device drivers enable the operating system to communicate with specific hardware devices. Firmware is software that is embedded in hardware devices, providing instructions for their operation. Therefore, systems software is the correct answer as it plays a crucial role in coordinating the interaction of technology devices.
