Answer:
Explanation:
One group of students did an experiment to study the movement of ocean water. The steps of the experiment are listed below.
Fill a rectangular baking glass dish with water.
Place a plastic bag with ice in the water near the left edge of the dish.
Place a lighted lamp near the left edge of the dish so that its light falls directly on the plastic bag.
Put a few drops of ink in the water.
The student did not observe any circulation of ink in the water as expected because the experiment had a flaw. Which of these statements best describes the flaw in the experiment? (2 points)
Not enough ink was added.
Not enough water was taken.
The dish was too small for the experiment.
The lamp and the ice bag were at the same place.
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:
a. True
Explanation:
PC's sometimes runs slowly and on the long run cost money. Optimizing performance involves running software utilities that could restore speed and efficiency.
Scanning for malware/ virus , cleaning system registry, uninstalling unused program, deleting unnecessary files, disk defragment , updating of windows software and setting up the browser are ways to optimize your pc's performance.
Well you can start by getting a app called CM Security Master....it frees junk files and stops viruses, etc.. If you want execive space get a SanDisk (SD) card with how ever much space you want.
