Translate each of these statements into logical expressions using predicates, quantifiers, and logical connectives. a) Something
yKpoI14uk [10]

Answer:

Let P(x) = x is in the correct place

Let Q(x) =  x is in the excellent place

R(x) denotes the tool

Explanation:

a) Something is not in the correct place.

P(x) is that x is in the correct place so negation of ¬P(x) will represent x is not in the correct place. ∃x is an existential quantifier used to represent "for some" and depicts something in the given statement. This statement can be translated into logical expression as follows:

                                                    ∃x¬P(x)

b) All tools are in the correct place and are in excellent condition.

R(x) represents the tool, P(x) represents x is in correct place and Q(x) shows x is in excellent place. ∀ is used to show that "all" tools and ∧ is used here because tools are in correct place AND are in excellent condition so it depicts both P(x) and Q(x). This statement can be translated into logical expression as follows:

                                       ∀ x ( R(x) → (P(x) ∧ Q(x))

c) Everything is in the correct place and in excellent condition.

Here P(x) represents correct place and Q(x) represents excellent condition ∀ represent all and here everything. ∧  means that both the P(x) and Q(x) exist. This statement can be translated into logical expression as follows:

                                              ∀ x (P(x) ∧ Q(x)

Answer:

Listed below are the few ways Linux Server can be secured

1. Group policies: This is a way to ensure security by applying group policies and permissions both on the group level and the files level. Through proper permission configuration we can easily restrict other users from accessing those files and directories.

2. Implementation of the firewall: Implementing firewall in each of the Linux server will definitely help in securing your machine from outside threats. Iptables will help in filtering the network traffic that are entering into the system and even going out of the system.

3.Enabling SELINUX: Enabling SELINUX is another way to secure your system especially a Linux Server. Selinux is a powerful security that checks and allows applications to run into the system. It won't allow any untrusted application to run into the system.

Which file contains full and incremental back-up information for use with the dump/restore utility?
Ivahew [28]

The file that contains full and incremental back-up information for use with the dump/restore utility is <u>/etc/dumpdates.</u>

<u></u>

<h3>What is dump/restore utility ?</h3>

Dump examines files in a filesystem, determines which ones need to be backed up, and copies those files to a specified disk, tape or other storage medium. Subsequent incremental backups can then be layered on top of the full backup.

The restore command performs the inverse function of dump; it can restore a full backup of a filesystem. Single files and directory subtrees may also be restored from full or partial backups in interactive mode.

Use python
Degger [83]

Answer:

def rec_dig_sum( num ):

   num_list = [ digit for digit in str(num)]

   total = 0

   for x in num_list:

       total += x

   return total

def dict_of_rec_dig_sums(low, high):

   mydict = dict()

   for number in the range(low, high+1):

      mydict[rec_dig_sum(number)] = number

   return mydict

Explanation:

The python program defines two functions, "rec_dig_sum" and "dict_of_rec_dig_sums". The former accepts a number and returns the sum of the digits of the number while the latter accepts a low and high number range.

The program returns a dictionary with the recursive sum as the keys and the number count as the values.
