The best scenario is when a program suffers from frequent
page faults. In the situations when a kernel thread experiences a page fault,
another kernel thread can be switched in; something a single-threaded process
will not be capable of doing. Another best circumstance is when a program has
to wait for other systems events.

Answer:
here is my crude attempt:
import turtle
t = turtle.Turtle()
t.speed(0)
colors = ["black", "yellow"]
SQUARES = 8
SQUARESIZE = 20
def rectangle(color, s):
t.begin_fill()
t.pendown()
t.color(color)
for i in range(4):
t.forward(s)
t.right(90)
t.end_fill()
t.penup()
for row in range(SQUARES):
for col in range(SQUARES):
t.setpos(row*SQUARESIZE, col*SQUARESIZE)
rectangle(colors[(row+col)%2], SQUARESIZE)
Answer:
True.
Explanation:
Virtualization can be defined as a technique used for the creation of a virtual platform such as a storage device, operating system, server, desktop, infrastructure or computing resources so as to enable the sharing of resources among multiple end users. Virtualization is usually implemented on a computer which is referred to as the "host" machine.
Generally, to use the virtualization technology on a computer, it must be enabled in the BIOS/UEFI).
Additionally, VMware tools can be installed on host computers to check which processes are having high CPU usage by using vimtop, as well as checking if vCenter Server is swapping.
Hence, one benefit of virtualization is that it allows for better use of already existing hardware that may not be seeing full utilization. Hardware components such as storage devices, central processing unit (CPU), random access memory (RAM), host computers are extensively put into use.
