Answer:
The answer is "except IOError:"
Explanation:
It is part of the exception handling, that stands for input/ output operation fails, this exception aeries when we attempting to access an anti-existent file, in the program so, it will give the program related errors.
- This type of error is handled in the try block, it also allows you to prepare the deal with the exceptional block.
- It also helps you to hide the bugs by using code, if you handle an unexpected error.
These principles are not explicit to one kind of program and are increasingly broad "best practice" rules that assist designers with composing code that is easier to maintain.
<u>Explanation:</u>
A set of programming guidelines that are executed to play out a particular undertaking according to the prerequisites of the client is known as programming. Every product has some essential standards to follow. In light of all product frameworks have basic quality traits, including accessibility, modifiability, execution, security and wellbeing, testability and ease of use, the key programming thoughts give basic arrangements or strategies to help those characteristics.
It is generally less expensive, over the long haul, to utilize programming designing strategies and methods for programming frameworks instead of simply compose the projects as though it was an individual programming venture.
Answer:
Attenuation.
Explanation:
Attenuation means a gradual reduction in the strength of a signal as it moves from station to station which may even cause the receiving station to misinterpret the signal. Any signal can be attenuated - digital or analog.
Attenuation is often caused by weakness, fatigue or passiveness of networking cables and connectors. It could also be caused by noise and long distance.
To get around this, the network device(s) will often resend signals multiple times over just to ensure that at least one of the signals gets there and is interpreted correctly.
