Answer:
All are True
Explanation:
a. A constructor must have the same name as that of a class. For example
public class MyFirstClass{ // this is the class name
public MyFirstClass() } // the constructor having the same name as class.
b. Constructors never have a return type not even void because it is only used to initialize the values of data members of the class when the object of the class is created so constructors are not directly called hence they do not need to have a return type.
c. Constructors are invoked using the new operator.
When the new object is created the constructor is invoked in order to initialize the variables of a class. The memory is allocated to the object and then the constructive is invoked for the purpose to initialize the object.
Answer:
1000/125 billion instructions per second.
Explanation:
All the stages take 125ps and latch time was outlooked.
The clock speed would be the highest stage time in all 5 stages. Here all are same clock speed it would be 125ps only.
throughput = 1/cycle time so ⇒ 1/125 instructions/ps
Since we want it in billion instructions per second so we have to multiply with 10⁻⁹ /10⁻¹² then the result is 1000/125 billion instructions per second.
A firewall determines what external network traffic(internet) should or should not be allowed to pass internal network(computer). A firewall is network security that protects software and hardware from untrusted sites that may have viruses, worms, and bugs that are detrimental to the computer.
