7 0

It's kind of a mix between A and C there are some defragmenting tools that show you how much of your PC is wasted by program files. And in some defragmenting tools, it shows you all the files that are fragmented and gives you the option to defrag them or not. So the best answer would be A.

Answer:

1111

11111

Explanation:

Given

The above QBasic code

Required

The output

The iteration on the third line is repeated 5 times; i.e. for values of j from 1 to 5.

In each iteration, the value of N is printed and the next value is calculated.

Initially, the value of N is 1 ---- on line 2

So, 1 is printed first. The next value of N is as follows:

$N = 10 * N + 1$ --- we keep replacing N (on the right-hand side) with current N value.

So, we have:

$N = 10 * 1 + 1 =11$

$N = 10 * 11 + 1 = 111$

$N =10 *111+1 = 1111$

$N =10 *1111+1 = 11111$

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.
