<span>There are 4 computer language generations. First is the first generation language or 1GL, second is the second-generation languages or the 2GL, next is the third-generation languages or the 3GL, and the last is fourth-generation languages or the 4GL.</span>
You have to trace it back to its source to determine it. Data cables are flat and cables are round.
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.
Answer:
b. the cluster centers for the current iteration are identical to the cluster centers for the previous iteration.
Explanation:
K-mean algorithm is one of the mot widely used algorithm for partitioning into groups of k clusters. This is done by partitioning observations into clusters which are similar to each other. When using k-mean algorithm, each of the different clusters are represented by their centroid and each point are placed only in clusters in which the point is close to cluster centroid.
The K-Means algorithm terminates when the cluster centers for the current iteration are identical to the cluster centers for the previous iteration.
The answer is definitely C. 3
