Explanation:

When you break into your computer, when you kept them at your home, you can use all private data and passwords. These data provide them with an opportunity to burden you with doing things you don't want to do. Within one day you can go bankrupt.

Following are the precautions to be taken:

  • Regular update of software-helps to patch the last vulnerabilities.
  • Keep the password of your computer secure and never share it with anybody who may be excluding your kids.
  • Doesn’t jail break your computer or root it. Although this can improve the device's efficiency, it is a profuse basis for hackers that do not use other built-in defenses. This is something people often do.
  • Use trusted sites to download the software.

Consider the following relation:CAR_SALE(Car#, Date_sold, Salesperson#, Commission%, Discount_amt)Assume that a car may be sold
GalinKa [24]

Answer:

The answer to this question can be given as:

Normalization:

Normalization usually includes the division of a table into two or more tables as well as defining a relation between the table. It is also used to check the quality of the database design. In the normalization, we use three-level that are 1NF, 2NF, 3NF.

First Normal Form (1NF):

In the 1NF each table contains unique data. for example employee id.  

Second Normal Form (2NF):

In the 2NF form, every field in a table that is not a determiner of another field's contents must itself be a component of the table's other fields.

Third Normal Form (3NF):

In the 3NF form, no duplication of information is allowed.

Explanation:

The explanation of the question can be given as:

  • Since all attribute values are single atomic, the given relation CAR_SALE is in 1NF.  
  • Salesperson# → commission% …Given  Thus, it is not completely dependent on the primary key {Car#, Salesperson#}. Hence, it is not in 2 NF.                                                                                                        

The 2 NF decomposition:

        CAR_SALE_1(Car#, Salesperson#, Date_sold, Discount_amt)

         CAR_SALE_2(Salesperson#, Commission%)

  • The relationship in question is not in 3NF because the nature of a transitive dependence occurs
  • Discount_amt → Date_sold → (Car#, Salesperson#) . Thus, Date_sold is neither the key itself nor the Discount amt sub-set is a prime attribute.  

The 3 NF decomposition :

        CAR_SALES_1A(Car#, Salesperson#, Date_sold)

        CAR_SALES_1B(Date_sold, Discount_amt)

        CAR_SALE_3(Salesperson#, Commission%)

Given the structure definition shown, assume that circle1 and circle2 are variables of the Circle type and their members have be
kolezko [41]

Answer:

False is the correct answer for the above question.

Explanation:

  • The structure is a user-defined data type, which is used to define the set of different data types and values. Just like in the above question, the class structure holds the list of three variables, which is a type of double.
  • When any user wants to compare the two structure values, then he can do it with the help of comparing all the variables of a structure. if a user wants to compare the circle1 with the value of the circle2, then he needs to compare the circle1.centerX with circle2.centerX, and so on with the other variables.
  • But the above question syntax will directly compare the two structure variable, which is not correct. Hence the above answer is false.
