Answer:
18000 seconds or 300 minutes.
Explanation:
In the example given in the question, it is stated that the system uses 32-bit unique salt which is equal to 4 bytes where every digit takes up 1 byte thus forming the 4 digit passwords.
Considering that the passwords are 4 digits, starting from 1000 and up to 9999, there are 9000 possible password combinations.
If Eve has to go through the whole range of possible password combinations and it takes her 1 second to guess 1 password. Then in the worst case scenario, it would take her 18000 seconds or 300 minutes to crack both accounts, assuming that it is possible for them to use the same passwords.
I hope this answer helps.
Answer:
Implicit type casting means the type casting done by the compiler during compilation of program whereas Explicit type casting means the programmer explicitly type casts the variables. This is the difference implicit and explicit type casting.
Explanation:
Type casting means the conversion of one data type into another data type. There are two types of type casting. They are Implicit type casting and Explicit type casting.
<u>Implicit type casting:</u> The type casting which is done by the compiler during the compilation of a program. This occurs when we assigning smaller data type to larger data type and also both the data type are compatible. Below example clears the above concepts.
Ex: 
In the above example " i " is " int " data type whereas " l " is long data type but as we assigned the value of " i " to " l ". Here " int " and " long " are compatible data types and we assigned smaller data type ( int - i ) to larger data type ( long - l ) implicit type casting occurs.
<u>Explicit type casting:</u> The type casting which is done by the programmer explicitly to convert one data type into other data type. If we want to assign a value of larger data type to smaller data type explicit type casting is required. Below example clears the above concepts.
Ex: 
In the above example " d " is " double " data type whereas " l " is " long " data type. Here we are explicitly type casting to change larger data value ( double - d ) to smaller data value ( long - l ).
Answer:
a. 6 bits
b. 1
Explanation:
Ans (a)
40 Characters need to be represent by binary coded Zebronian (BCZ) , So You will need 6 bits.
5 bits wold only give you 32 = 2 x 2 x 2 x 2 x 2 unique characters.
So 6 bits would allow you to represent 64 characters.
Ans(b)
BCD = Binrary Coded Decimal is very common in electronics, particularly it displays numerical data.
BCD Encodes each digit of a decimal number into 4 digit binary form.
Each decimal digit is indiviidually converted to oits binary equivalent
For Example : 146 , the decimal degits are replaced by 0001 , 0100 and 0110 respectively
Addition
1 0 = 10 is binary value of 2 2
+1 1 = 11 is binary value of 3 + 3
---------- -----------
1 0 1 5 Ans
Subtraction
1 1= binary value of 3 3
- 1 0 = binary value of 2 - 2
--------- -----------
0 1 1 Ans
Answer:
The correct answer to the following question will be Option B (Policy).
Explanation:
- The Policy is a systematic set of rules for driving policies and obtaining rational results. It is a declaration of intent and is applied as a process or protocol.
- Policies are usually implemented by the governing body throughout the corporation.
- It was the feature of Information assurance management, which sought to dictate those activities throughout the organization via a collection of institutional requirements.
Therefore, Option B is the right answer.
You'll probably see numbers counting up, like 1 2 3 4 ...
