Answer:
enhanced for loop
Explanation:
Enhanced for loop is an improve concept about loops, this features was implemented in Java SE 5.0 version, this method simplify the For structure. For example:
for (int i = 0; i <array.length; i ++) {
System.out.print (array [i]);
}
Enhanced for loop
for (String element : array) {
System.out.print(element);
}
Answer:
A. The function definition must appear before the function is called
Explanation:
Given
The above lines of code
Required
Determine the error in the program
In python, functions has be defined before they are called but in this case (of the given program), the function is called before it was defined and this will definitely result in an error;
<em>Hence, option A answers the question</em>
The correct sequence of the program is as follows:
<em>def evenOdd(n):
</em>
<em> if n % 2 == 0:
</em>
<em> return "even"
</em>
<em> return "odd"
</em>
<em>num = int(input("Enter an integer: "))
</em>
<em>print("The integer is", evenOdd(num))
</em>

A network administrator notices that some newly installed Ethernet cabling is carrying corrupt and distorted data signals. The new cabling was installed in the ceiling close to fluorescent lights and electrical equipment
Two factors may interfere with the copper cabling and result in signal distortion and data corruption are :
EMI
RFI
Explanation:
- EMI (electromagnetic interference) is the disruption of operation of an electronic device when it is in the vicinity of an electromagnetic field (EM field) in the radio frequency (RF) spectrum that is caused by another electronic device.
- During EMC testing, radiated emissions measurements are made using a spectrum analyzer and or an EMI receiver and a suitable measuring antenna.
- EMI (Electromagnetic Interference) is also called RFI (Radio Frequency Interference).
- Conducted RFI is unwanted high frequencies that ride on the AC wave form. Radiated RFI is emitted through the air. There are many pieces of equipment that can generate RFI, variable frequency drives included.
- The internal circuits of personal computers generate EM fields in the RF range.
A Savings Vehicle is an effective way to hold your savings. It could be a savings account. But some requires a high minimum balance such as Certificate of Deposit (CD). It is generally issued by commercial banks. It is a time deposit too and restricts you from withdrawing funds.
