Answer: Falsifiability
Explanation: Falsifiability is the term that is defined as the evaluation of any particular hypothesis or theory to be proven wrong .This feature gives the access that the theory can be tested and have more accurate claims .
The ESP(Extrasensory perception) theory can also have feature of being falsifiable because the experiments and test lead to the issue that the negative effects of the theory are not certain which might occur due to simple observation of effects.
Answer:
Static scoping: x is 5
Dynamic scoping : x is 10.
Explanation:
Static scoping :
In static scoping the variable of a function take the value within the function.
If there is no values exist within the function then take the global value of the variable.
var x // No value is assigned to x so it check global value of x
function sub1() {
document.write(“x = “ + x + “”); // So it print x = 5
}
function sub2() {
var x;
x = 10;
sub1();
}
x = 5; // It is the global value of x
sub2();
Static scoping: x is 5
Dynamic scoping :
In Dynamic scoping the variable of a function take the value all the calling function ends.
If the global value is the last assigned value of a variable then it take that value.
If there exist some other function after global variable value if that function contain the variable with some assigned value variable take that value.
var x
function sub1() {
document.write(“x = “ + x + “”);
}
x = 5; // At this point x value is 5 and check there exist a function
sub2(); // So now call this function
function sub2() {
var x;
x = 10; // The value of x = 5 is replaced with x = 10
sub1();
}
Dynamic scoping : x is 10.
Answer:
The answer is reflective DNS attack
Explanation:
Reflective DNS Attack is used in many distributed DDoS attacks to knock down an internet pipe. The attack is divided in two stages: first the attacker sends lots of requests to one or more legitimate DNS servers while using spoofed source IP of the target person, and then, in the second stage, the DNS server receiving the semi-legitimate requests replies to the spoofed IP, thereby unknowingly lauching an attack on the target computer with responses to requests never sent by the victim.
Over the years, the internet has undergone major changes that has positively and negatively affected the overall interface, performance, and design of the entire website. Apart from this, it has completely changed the communities point of views towards technology and its appreciation of the market designs.

Growing professionally comes with advises, comments (solicited and unsolicited), request for favours and also contributions. Moving up your professional career from the days of little beginning have always been accompanied with all of the requests and comments. As one levitates successfully, requests and contributions tend to increase. This can be scary and at the same time tiring as you go to question the sensibility of some of your decisions. While being inundated with these ’assistance', it is important that you carefully and thoroughly select the comments, contributions, requests of favours etc that is worth responding to. While some would be considered others will be discarded. Now, the question is how best can we politely turndown a person's request of favours and contributions without sounding rude, ungratetul and condescending. Both useful and irrelevant contributions deserve good responses. We could start by appreciating the request for favours and contributions, and tell whomsoever it may concern that you appreciate his/her assistance but unfortunately would not be needing them.
