Answer:
The answer is below
Explanation:
1. Lack of password enforcement
2. Outdated third party applications: this includes outdated software such as Apache, PHP, MySQL, OpenSSL, and VNC
3. General lack of patch management for the OS
4. General lack of system hardening:
5. Lack of backups
Ways to hardened the Linux/Unix based computer system is do the following:
1. Perform minimal Installation: this involves, installing softwares that are necessary, and limiting the number of admin users on the computer system.
2. Carry out Code Auditing: this is a means of preventing security issues, by withing more secure softwares to prevent variable declarations, or otherwise unexpected logic.
3. Ensure there is a Traffic filter firewall: this will helps to attacks from external users or hackers. Install, Web Applicatio firewall, which helps to filter out traffic.
4. Carry out Softwares updates: a software update can help prevent or guide against security leaks in a software
5. Install security updates only: this is done by filtering out the security-related programs and only upgrade packages which are referred to in the custom file.
b. Surge suppressor
c. CRT
d. UPS
Answer: A) Battery backup
Explanation:
A battery backup are used to provide the source of power backup to various hardware components and desktop computers. In many cases, the devices are plugged into UPS ( uninterruptible power supply) for backup power and it is also depend upon the size of the UPS.
All the battery backups are located inside so that is why, the devices are heavy in weight. Usually, the battery backup front required additional button for performing various functions.
And the battery backup devices are manufacture by using the varying degree of backup abilities.
Answer: syntax is a set of rules for grammar and spelling. In other words, it means using character structures that a computer can interpret

The overall goal of this function is to take a list of words that we got as input, a list of words to check for if they appear in the input outputs to return if something from the list to check is in the input list.
Define a function, called selector.
This function should have the following inputs, outputs and internal procedures:
Input(s)
input_list - list of string
check_list - list of string
return_list - list of string
Output(s):
output - string, or None
Procedure(s):
Initialize output to None
Loop through each element in input_list
Use a conditional to check if the current element is in check_list
If it is, assign output as the returned value of calling the random.choice function on return_list
Also, break out of the loop
At the end of the function, return output Note that if we don't find any words from input_list that are in check_list, output will be returned as None.
Answer:
See explaination
Explanation:
# Import required the module.
import random
# Define a function selector() which accepts the
# input_list, check_list, and return_list and
# returns a string named output.
def selector(input_list,check_list,return_list):
# Assign None to string variable output.
output=None
# Use for loop to traverse through input_list.
for i in range(len(input_list)):
# Check if element of an input_list is present
# in check_list.
if input_list[i] in check_list:
# Assign a random value from return_list
# to output.
output=random.choice(return_list)
# break out of the loop if input_list
# element is present in check_list.
break
#
return output
# Use assert statement to test a condition.
# If the condition is true, then program continues to
# execute, otherwise raises an AssertionError.
assert callable(selector)
assert selector(['is','in','of'],['of'], ['Yes']) == 'Yes'
assert selector(['is','in'],['of'], ['Yes','No']) == None
# Display the output.
print(selector(['is','in','of'],['of'], ['Yes']))
print(selector(['is','in'],['of'], ['Yes','No']))
B. 345.0.24.6
C. 54.45.43.54
D. 255.255.255.0
The valid IPv4 addresses are A. 1.1.1.1, C. 54.45.43.54, and D. 255.255.255.0
Valid IPv4 addresses are 32 bits in size and normally contain three periods and four octets like 1.1.1.1, and the value can be any number from zero to 255.
IPv4 means Internet Protocol version 4. It is a set of address that identifies a network interface on a computer.
Thus, the only invalid address according to IPv4 standards is B. 345.0.24.6, with others regarded as valid IPv4 addresses.
