D
Explanation:
All three of A, B and C are required to harden a host. Thus, All of the above makes the best option.
Hardening simply refers to making your data impossible to be penetrated. More like bulletproof.
To do this, ensure measures like
- Regular Program cleanup
- Patches management
- service pack installation
- service or usage policies
...among others.

Explanation:
For the view of Exercise 4.18, explain why the database system would not allow a tuple to be inserted into the database through this view.
For reference
For the database of Figure 4.12, write a query to find the ID of each employee with no manager. Note that an employee may simply have no manager listed or may have a null manager. Write your query using an outer join and then write it again using no outer join at all.
OUTER JOIN
select e.ID from employee e left outer join manages m on e.ID = m.ID
where m.manager_id is null;
NO OUTER
select e.ID from employee e where e.ID not in (select m.ID from manages m) or e.ID in (select m.ID from manages m where m.manager_id is null);
Answer:
def newton(n):
#Define the variables.
t = 0.000001
esti = 1.0
#Calculate the square root
#using newton method.
while True:
esti = (esti + n / esti) / 2
dif = abs(n - esti ** 2)
if dif <= t:
break
#Return the result.
return esti
#Define the main function.
def main():
#Continue until user press enters.
while True:
try:
#Prompt the user for input.
n = int(input("Enter a number (Press Enter to stop):"))
#display the results.
print("newton = %0.15f" % newton(n))
except:
return
#Call the main function.
main()
This is called a "heat sink", essentially, a metal plate makes indirect <span>(its separated by thermal paste)</span> contact with the heat spreader of a cpu (central processing unit). The concept is that the heat sink is made of highly conductive materials thus conducting heat away from the CPU, quite often you'll find a fan attached to further disparate heat away from the heat-sink. These days you'll alternative cooling methods, the most common alternative is to use watercooling (another topic). GPU (graphic processing units) also have heatsinks.
