Answer:
213
Explanation:
The given parameters are;
The network on which the host is on = 192.168.146.0
The subnet mast = 255.255.255.0
The binary value of the host portion = 11010101
To convert the binary value to decimal value, we proceed by multiplying each of the digits of the binary value by the corresponding power of 2, from the left to right, starting from a power of 0, and sum the result, as follows;
(11010101)₂ = (1×2⁷ + 1×2⁶ + 0×2⁵ + 1×2⁴ + 0×2³ + 1×2² + 0×2¹ + 1×2⁰)₁₀
1×2⁷+1×2⁶+0×2⁵+1×2⁴+0×2³+1×2²+0×2¹+1×2⁰= 128+64+0+16+4+1 = 213
∴ (11010101)₂ = (213)₁₀
The decimal value of 11010101 is 213.
D.
Texting is associated with instant messaging
Answer:
AES or Rijndael is one example of a symmetric encryption algorithm.
Explanation:
With these type of algorithms, the key for encrypting is the same as for decrypting, so sender and receiver need to safely share this key without any third party getting a hold of it.
Answer: Primary Research (Focus Group).
Explanation:
Exploratory Research is an inquiry that seeks to understand the basic causal factors of a problem. This effort can serve as the basis of more intensive research later on.
There are basically two methodologies used, which are the; Primary and Secondary methods. While the Primary method's source of information is the concerned group, the Secondary Methods obtain their information from already existing information (Primary sources), such as Interviews, Journals, etc.
In the case of the company in the question, seeking to gain insight into the changes in a product, it would be best for them to consider what some selected costumers (focus group), think about the existing products and their views on subsequent changes. This method of getting information directly from the focus group employs the primary method.
