Aserver, also called a(n) operating system is a multiuser operating system because it controls a central computer that can support many users.

Assume that you have an array of integers named a. which of these code segments print the same results? int i = 1; while(i < a. length) { system. out. println(a[i]); i++; } int i; for (i = 0; i < a. length; i++) { system. out. println(a[i]); } for (int i : a) { system. out. println(i); } i and ii only ii and iii only i and iii only all three print the same results. all three print different results.

Robots with telescoping arms are sometimes used to perform tasks (e. g., welding or placing screws) where access may be difficult for other robotic types. during a test run, a robot arm is programmed to extend according to the relationship r = 3 + 0.5cos(4θ) and the arm rotates according to the relationship θ=−π4t2+πt , where r is in feet, θ is in radians, and t is in seconds. use a computer program to plot the path of tip a in x and y coordinates for 0 ≤ t ≤ 4s.

Designing a mobile web page is a little different from designing a regular web page. name at least three features that should be considered when designing a website that is mobile phone-friendly, and briefly explain why they are important.
