Answer:
(a) Correlated.
Explanation:
Correlated subquery :These sub queries reference columns from outer table or uses values from outer query.These sub queries are processed atleast once for every row processed.So because of this reason correlated sub queries can be slow.Since the query in the question also uses value from the outer query so it is a correlated query.
It is identified by its address number.
Boolean operators are like AND,or,not,and not .
they are <span>used as conjunctions to combine or exclude keywords in a search, resulting in more focused and productive results.</span>
Answer:
Bus Topology
Explanation:
In local area networks (LANs), Bus topology is used to connect all the computers on the single cable. This cable is called backbone of the network. In this type of network when a computer sends data, it will be received on entire network.
For Example
In water line system, all the taps that are connected to single pipe. If the pipe or a single tap broken this will affect the whole system.
Entire system can be crash if any node or wire will break.
This for loop will output:
0
2
4
The range(3) is all the integers between 0 inclusive and 3 exclusive. 0, 1, 2.
Every iterations through the for loop, we multiply the value of each number by 2 and print it to the console.
0 * 2 = 0
1 * 2 = 2
2 * 2 = 4
I hope this helps.
