<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.

Answer: Arial belongs to the sans serif family of typefaces. It is the most commonly used typeface, and it is the default typeface set in Microsoft Word. A character is a typographic element represented through an upper- or lowercase letter, number, or special character. Every letter of the alphabet has multiple parts that we describe with a particular set of terms. Typographers call this “letter anatomy.” The basic terms common to all letters are below:
An ascender is the stroke extending upward, going above the x-height (which is the height of the letter excluding the ascender or descender).
A descender is the stroke extending downward from the baseline (which is the imaginary horizontal line that aligns the bodies of the characters).
A bar is the horizontal stroke in the uppercase letters A, E, F, H, I, and T, as well as in the lowercase letters e, f, and t.
A counter is the blank space within the body stroke.
A bowl is a curved stroke that surrounds the counter.
A shoulder is a curved stroke beginning at the stem.
A serif is the tapered feature at the end of a stroke. Arial is a sans serif font, and it does not have tapered corners at the ends of the main strokes.
I would probably say B even though the other methods might work as well
