Answer:
Abstraction refines concepts to their core values, stripping away ideas to the fundamentals of the abstract idea. It leaves the common details of an idea. Abstractions make it easier to understand code because it concentrates on core features/actions and not on the small details.
This is only to be used for studying purposes.
Hope it helps!
B. -2
C. "Open"
D. +2
Answer:
D. +2
Explanation:
The given function is an IF function where the first argument is a logical test, the second argument is the result if the logical test is true and the third argument is the result if the logical test is false. Depending on whether the result of the logical test is true or false, the respective value will be returned.
IF(logical_test, value_if_true, value_if_false)
In this case, the logical test first compares the value of B3 and D5. As B3 is not greater than D5, the result is false and the value for false will be returned. The value for false result of the logical test is equated by D5-B3 which is equal to 2. Thus the result of the IF function is +2.
Answer:
Polynomial Zero() ::= return the polynomial p(x)=0
Boolean isZero(poly) ::= return (poly == 0)
Coefficient Coeff(poly , expon) ::= If (expon tex2html_wrap_inline93 poly) return its corresponding coefficient else return 0

Answer:
It returns the lookup value located in a specific location.
Explanation:
Answer:
'='
Explanation:
The equal ('=') is the character that is used to assign the value in the programming.
In the programming, there is a lot of character which has different meaning and uses for a different purpose.
like '==' it is used for checking equality between the Boolean.
'+' is a character that is used for adding.
'-' is a character that is used for subtraction.
similarly, '=' used for assigning.
for example:
a = a + b;
In the programming, the program evaluates the (a + b) first and then the result assigns to the variable.
ii. How do the first three security concepts relate to these four attacks
Answer and Explanation:
I and II answered
Interruption: interruption occurs when network is tampered with or communication between systems in a network is obstructed for illegitimate purposes.
Interception: interception occurs when data sent between systems is intercepted such that the message sent to another system is seen by an unauthorized user before it reaches destination. Interception violates confidentiality of a message.
Modification: modification occurs when data sent from a system to another system on the network is altered by an authorized user before it reaches it's destination. Modification attacks violate integrity, confidentiality and authenticity of a message.
Fabrication: fabrication occurs when an unauthorized user poses as a valid user and sends a fake message to a system in the network. Fabrication violates confidentiality, integrity and authenticity.
