I know the first one shown in the picture but I can't see the one under it I can help you if you can show the whole problem under the first problem.
<u>Explanation:</u>
a.
- One user can read the private data of another user-privacy.
- One user can prevent another user from getting anything done-denial of service.
Indeed, in any multiprogramming and time-sharing environment since the computers of users are networked together, then it is very possible for a bad actor to read the private data of another user, or even prevent another user from accessing their computer by employing a denial of service attack on the network. In other words, the network would be unable to handle the request of users since has been overloaded by another user.
b. a. Yes - if we can ensure that the operating system prevents any sharing of data between users, either for reading or writing and fairly shares the computer, then we can achieve the same level of security.
Disk Defragmenter
A disk defragmenter is a utility that reorganizes the files and unused space on a computer's hard disk so that the operating system accesses data more quickly and programs run faster.
Answer:
Its outfile<<number.
However, before this we need to write
outfile.open("xyz.txt", ios;;out)
outfile<<number
And this code will do what is required in the question. This is going to write the number's content to the xyz.txt file which is the file associated with the outfile.
And remember this is in C++. And C++ is a imperative oriented programming language. Undoubtedly, Python and R are fully object oriented programming languages.
Explanation:
The answer is self explanatory.
Yes, Using programming libraries is one way of incorporating existing code into new programs is a true statement.
<h3>What function do libraries provide in programming?</h3>
Programming libraries are helpful resources that can speed up the work of a web developer. They offer prewritten, reuseable portions of code so that programmers can easily and quickly create apps. Consider building a program that enables users to enroll in and pay for courses.
Therefore, Using a code library often saves developers from having to create everything from scratch. It can take less time to develop projects and have more reliable software if the catalog of programming resources is kept up well.
