Answer:
Bluetooth is a wireless communication is typically limited to six feet distances
Explanation:
Bluetooth is one type of communication maximum it covers 10 meters to 30 meters. but it is one to one communication made for data transactions. After 25 meters of coverage on communication will be very slow on data transactions. But Bluetooth has also had a limitation.
IR. It is one of communication where infrared technology used. It is like face to face communication and speed of data transaction limited and it is also one to one communication made for data transactions. Communication paired and covered very little distances.
NFC it is chip-based and covers very little in fact just to device meet each and communication started. And very it caries very little data during the data transactions. it is also one to one communication made for data transactions
RFID is one of communication and it is powerful to cover more areas with multiple connections at the same time. It has a limitation in distance and it covers like a net with a specific distance
Answer:
Explanation:
The following piece of code is written in Java. It creates the method as requested that takes in two generic objects and compares them using the .equals() built in Java method. This method will return True if the objects are identical or False if they are not. A test case is used in the code and the output can be seen in the attached image below.
public static <T> boolean comparePerez(T a, T b) {
return a.equals(b);
}
Answer and explanation :
the three control problems associated with competing process are
- MUTUAL EXCLUSION : We know that some resources are shareable and some are not shareable. which means only one process can access the resource at a time this type of resources are called critical resources this code can be access at only one process at a time. the other process if required to access should not be allowed
- DEADLOCK: this hold the process without complete for example suppose there are two resources R1 and R2 and two process P1 and P2 and P1 use R1 and P2 use R2 but after some time when P1 needs R2 but R2 is not available as it is used by P2 so the all process will be on hold
- STARVATION : when priorities are given to the process as high priorities and low priorities. And high priorities process always competing then low priorities process have to wait for very long time this is called starvation
Answer:
Security Tab is the correct answer.
