Answer:
The factorial of 3=6
Explanation:
Following are the description of the given question
- This is JavaScript code .Here items are the variable that are holding the integer value "3".
- After that there is 2 loop are iterating one is outer and one inner loop.
- When i=1 1<=3 the condition of outer loop is true the control moves the inner loop .
- In the inner loop there is variable result that is initialized by 1 Now checking the condition of inner loop j=i i.e j=1 1>=1 condition of inner loop is true it executed the statement inside the inner loop so result =1 .Now we increment the value of i of the outer loop.
- i=2 2<=3 the condition of outer loop is true the control moves the inner loop .
- In the inner loop there is variable result that is initialized by 1 Now checking the condition of inner loop j=i i.e j=2 2>=1 condition of inner loop is true it executed the statement inside the inner loop so result =2 .Now we increment the value of i of the outer loop.
- Now i=3 3<=3 the condition of outer loop is true the control moves the inner loop .
- In the inner loop there is variable result that is initialized by 1 Now checking the condition of inner loop j=i i.e j=3 3>=1 condition of inner loop is true it executed the statement inside the inner loop so result =6 .Now we increment the value of i of the outer loop.
- i=4 4<=3 the condition of outer loop is false the control moves from the outer loop.
- It print The factorial of 3=6
Answer: D) DHCP snooping
Explanation:
DHCP stand for the dynamic host configuration protocol and it is basically use as the DHCP server. It provide the IP address to each device in the network and it is used to communicate with the other IP network.
According to the question, the student device basically receive the IP network and it is an unauthorized DHCP server which uses denial of service attack for several purposes.
DHCP snooping is basically use to prevent from such unauthorized device which gives the IP address to the clients. DHCP is the two layer security system technology that is bulit in the operating system.
Well in control panel you change the features or sounds, if it has an issue like a virus you should take it somewhere to get it fixed
