Answer:
The technologies that Ann will MOST likely use to connect the pedometer to her desktop to transfer her information to the website are:
a. Bluetooth
and
c. NFC
Explanation:
Bluetooth and NFC (Near Field Communication) are wireless technologies that enable the exchange of data between different devices. Bluetooth operates on wavelength. NFC operates on high frequency. The security of NFC over Bluetooth makes it a better tool of choice. NFC also operates on a shorter range than Bluetooth, enabling a more stable connection. NFC also enjoys a shorter set-up time than Bluetooth. It also functions better than Bluetooth in crowded areas. Tethering requires the use of physical connectors. Infrared is not a connecting technology but wave radiation.
Answer:
Yes, The overall cost of wiring in addressable fire alarm system is significantly cheaper than the conventional one.But the addressale fire alram system is more reliable than a conventional system.
Explanation:
Conventional systems are hardware-based and use analog technology. where addressable fire alarm use digital technology. addressable system is generally more reliable than a conventional system mainly due to how the different systems are wired. With a conventional system, if a device’s wire is damaged or severed, its signal and the signal of other devices down the line cannot be transmitted to the control panel.
With an addressable system, both ends of the wire connect to the control panel. Therefore, if one end becomes damaged or severed, signals can still reach the control panel through the other end of the loop. In addressable systems, a device can be removed or disabled and it will not affect the other devices in the loop.

<span>The options attached to the question above are as follows:</span>
<span>
A. Light-Emitting diodes are used as
indicators in circuits
B. Light-Emitting diodes are used as defectors in circuits
C. Light-Emitting diodes have very short life-spans in circuits
D. Light-Emitting diodes conduct current in either direction in circuits</span>
ANSWER
The correct option is A.
Light emitting diodes [LED] refers to a semi conductor diode that glows when current flows through it by converting electrical energy into light. LED has many applications and one of it is that is used as an indicator in electric circuits. The circuit symbol of LED is made up of two arrow marks, which is used to indicate the radiation that is emitted by the diode.
