Explanation of Solution

Bluetooth

  • Bluetooth devices are used to transmit low power wireless data with devices in small range distance at the range of 10cm (Centimeter) to 30m (Meter).
  • Bluetooth devices contain higher transfer rate at the range of 722 kbps (Kilobits per second).
  • It is low-cost and easy to install, simple and convenient to use, and many applications can be transmitted using the device.
  • The Bluetooth is used to transmit between music players such as mobile phones to headsets.
  • It will connect one computer with another computer.

 Wireless-Fidelity (Wi-Fi):

  • It has third generation wireless access connection. In this, the data is transmitted to or from the node points within the radius range.
  • The radius of the network ranges up to meters. The node point is connected to a wired network and shares the data with wireless users.
  • It is connected through Local Area Network (LANs), and Wide Area Network (WANs).

WiMAX:

WiMAX stands for Worldwide Interoperability for Microwave Access.

  • WiMAX is the forthcoming new technology standard for long distance wireless communications.
  • The WiMAX technology is designed to join the Wi-Fi and DSL (Digital Subscriber Line).
    • Short range wireless communication is covered by Wi-Fi technology.
    • Long range wired communication is covered by DSL technology...

Explanation of Solution

Capabilities and suitable applications of each types of technologies:

Bluetooth

  • It provides only limited access and is used to create small personal-area network.

Wi-Fi

  • It covers from 30 meters to 50 meters and is used to create small local-area network...

Explanation of Solution

 Radio Frequency Identification (RFID):

  • RFID is a mobile wireless technology that is used to facilitate supply chain management.
  • Movement of data is tracked by RFID. It captures and provide instant goods movement information between the supply chain partners.

 Working of RFID:

  • RFID system provides a microchip that contains the details of an item and its location...

Explanation of Solution

 Wireless Sensor Data (WSN):

 It is a network of organized wireless devices. A network consists of thousands of nodes.

 It helps to observe the building security or to detect harmful substances in the air.

 Working of WSN:

  • The WSN is a network of interrelated wireless devices with some processing and radio-transmitting capacity that are embedded into the physical environment to give measurements of various points over huge spaces...

(Short-answer) b. Continue from the previous question. Suppose part of the data you extracted from the data warehouse is the following.   Identify the missing values you think exist in the dataset. Use Column letter and Row number to refer to each missing value in the dataset. Please write down how you want to address each particular missing value (you can group them if they receive same treatment). For imputation, you do not need to calculate the exact imputed values but just describe what kind of value you want to use to impute.
Please original work Locate data warehousing solutions offered by IBM, Oracle, Microsoft, and Amazon Compare and contrast the capabilities of each solution and provide several names of some organizations that utilize each of these solutions. Please cite in text references and add weblinks
