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

Answer / kishan

EMI( electromagnetic interference). it is due to different
electromagnetic devices present in the surrounding. that
create the problem of interfering.

Answer / manpreet singh

Electromagnetic Interference (EMI)

All electronic devices give off electromagnetic emissions.
This is radiation that is a byproduct of electrical or
magnetic activity. Unfortunately, the emissions from one
device can interfere with other devices, causing potential
problems. Interference can lead to data loss, picture
quality degradation on monitors, and other problems with
your PC, or problems with other devices such as television
sets and radios. These are generally categorized as
electromagnetic interference or EMI problems.

There are actually two different issues here: EMI emissions
by the PC, and EMI emissions received by the PC. PCs
generally do not cause very much interference with other
devices; they are required by the Federal Communications
Commission (FCC) to be certified as Class B devices. This
certification is used to show that the PC conforms to
standards that limit the amount of EMI that a PC can
produce. The only catch to this is that you have to keep
the cover on the PC. This is one reason why the cover is
always made from metal. (Keeping the cover on is also an
important part of ensuring proper ventilation).

PCs can be affected by electromagnetic interference from
other devices, in two major ways. One is direct effects
through proximity with other devices; another is electrical
interference over the power lines. Most PCs generally do
not have many problems with EMI, but those that do can
cause incredible frustrating to their owners. There are
several things that you can do to avoid or at least reduce
EMI if you think it is affecting your PCs:

I am stuck up with a question on appending of two arrays I am writing the code for the same, I am appending two strings this way int main() { string s1 = "Welcome to C++"; string s2 = "C++ improves the logic ability"; string s3 = s1 + s2; cout<<s3<<endl; } But if I go ahead with the integer datatype , it doesnt work int main() { int arr[4] = {2,3,4,5}; int arr1[4] = {6,7,8,9}; int arr3[9] ; arr3 = arr + arr1;//displays error arr3 = arr ++ arr1; // works properly } Can anyone please clear my doubt in this question ?
