They are both IP packets; both TCP and UDP use IP as their basis. TCP is used to create a channel with flow control, UDP just sends single packets that may get lost.
Answer:
x=2
x=1
x=2
Explanation:
a)
This if statement if (1+2=3) checks if the addition of two numbers 1 and 2 is true. Here the addition of 1 and 2 is 3 which is true. So the condition becomes true.
Since the condition is true x:=x+1 statement is executed. This statement means that the value of x is incremented by 1.
The value of x was 1 before the if statement is reached. So x:=x+1 statement will add 1 to that value of x.
x:=x+1 means x=x+1 which is x=1+1 So x=2
Hence value of x is 2 (x=2) after the execution of x:=x+1
b)
In statement b the value of x will be 1 because both the mathematical operations in the if statement evaluate to false.
which means in b, x:=x+1 will not be executed and value of x remains unchanged i.e x=1
In (c) the value x will be 2 because the condition in the if statement is true. Both mathematical expressions 2+3=5 and 3+4=7 are true. Therefore x:=x+1 will be executed and value of x will be incremented by 1. Hence x=2
I usually use the Ohm meter to check for resistance. If the circuit completes, the measurement is negligible.
The answer is option C: Use ground-fault circuit interrupters, and inspect extensions cords and portable tools.
Inspecting the extension cords needs to be done constantly, or there can be abrasions or cuts that won't be noticed. Option B remains one of the most important ways to be safe around electricity. Always wear non-conductive safety equipment, such as safety goggles or rubber gloves. You should also avoid touching exposed metal. Option C indicates one of the two ways that do not help you stay safe around electricity. A ground fault interrupter only works if there is a short circuit or a huge amount of energy going through that point and thus, will not effectively protect you from possible incidents with electricity.
Answer:
In my personal opinion, the pandemic has definitely changed the way that things are taught. An example of this would be that since a lot of work was delivered online in the past year, now if there was a day where, say the teacher was off, or the school was shut, there would now be a way to get the work to students easily.
There is some quality in online learning, as it allows for students to work from the comfort of there own home, which to some may make them work better than sat in a classroom. However, to other students, online learning may be bad for many reasons, such as internet issues, or if they don't have a computer.
