Answer:
True.
Explanation:
"1" to "M" or 1 to many is a type of relationship between tables in a relational database. It means that against 1 record in a table, there can be 0 to many rows in the other table. Not that the many or child table doesn't need to have any record against the 1 or parent row, so the many side is optional.
Example can be a Customer and Order relationship. Where Customer is the parent table and Order is the child table. "A customer can have 0 to many orders".
Answer:
Z-Wave
Explanation:
1. Wi-fi because it is always encrypted. This is good because Bandwidth is high—up to 2 MHz, however it only works if the signal is strong and device is close to the access point. Its average range is between 30 to 100 meters. This drawback only makes this technology not a good option.
2. ZigBee because it is always encrypted, ZigBee has lot of edge like largest number of device to connect 6500 theoretically, low power usage, faster and others compared to other which would have made it a better option to recommend to my company but it has interoperability issues
3. Z-Wave because it is the fastest wireless standard apart from this Z-wave has better interoperability, reliability, low frequent which does not interfere with Wi-Fi network, maintain backwards compatibility across all versions which is good for maintenance, Z Wave network to have greater ranges and ability to “bend” around obstacles.
4. Bluetooth because it is easiest to configure Low Energy (LE) is better at conserving power, it has a much longer range compared to others —up to 300 feet, under ideal circumstances—its low transmission rate will keep it from being used for data-heavy applications such as video.
In view of security and distance and compared with other IoT protocol i would recommended Z-Wave

Answer:
c. StringBuilder
Explanation:
An alternative to the String class would be the StringBuilder Class. This class uses Strings as objects and allows you to mix and match different strings as well as adding, removing, implementing, and modifying strings themselves as though they were similar to an array. Unlike the string class StringBuilder allows you to modify and work with a combination of strings in the same piece of data as opposed to having various objects and copying pieces which would take up more memory.
