Answer: all the answers are correct
Explanation:
Partial mesh networks is simply a packet switching networks which is connected and require that there should be establishment of a circuit before the exchange of packets.
Partial mesh networks are less expensive to implement when they're being compared to the full mesh networks and are also less redundant.
The correct statements regarding partial mesh networks are:
•the number of links connecting nodes in a partial mesh network depends upon the availability and reliability requirements of the network
• switches play an integral role in a partial mesh network, where several paths through the network are available
• redundant links and switches are used to improve the availability and reliability of partial mesh networks
Answer:
The boom of online courses, where anyone can learn from the comfort of one’s own home or office at their own chosen time is the main cause. When online courses made their foray a decade ago, the same question of technology replacing teachers in schools emerged as a major argument. However, if we ask you today whether calculators can replace mathematics teachers at school, what would you say? Sounds weird, right! Do you think calculators which are also a kind of a technological advancement only, are capable enough of themselves, so as to replace the teachers? The answer is obvious. It’s an obvious No!
D. all of these, since it depends on how the cell is formatted.
Answer:
There are no statements in the question, so I explained the whole code.
Explanation:
A map consists of key - value pairs. The put method allows you to insert values in the map. The first parameter in the put method is the key, and the second one is the value. Also, the keys must be unique.
For example, map.put("123", "John Smith"); -> key = 123, value = John Smith
Even though the key 123 is set to John Smith at the beginning, it will have the updated value Steve Yao at the end. That is because the keys are unique.
Note that the key 222 also has Steve Yao for the value, that is totally acceptable.
