n a poll, 6767% of Internet users are more careful about personal information when using a public Wi-Fi hotspot. What is the probability that among threethree randomly selected Internet users, at least one is more careful about personal information when using a public Wi-Fi hotspot? How is the result affected by the additional information that the survey subjects volunteered to respond?
Answer:
The probability that among three randomly selected Internet users, at least one is more careful about personal information when using a public Wi-Fi hotspot is 0.964
If the survey subjects volunteered to respond , then those with the strongest opinions are most likely respond. The survey sample is then not randomly selected, the survey may have a response bias.
Explanation:
Let P(at least one is more careful about personal information when using a public Wi-Fi hotspot) denote the probability that among three randomly selected Internet users, at least one is more careful about personal information when using a public Wi-Fi hotspot, then we have the equation
P(at least one is more careful about personal information when using a public Wi-Fi hotspot) = 1 - P(none of the selected users is more careful about personal information when using a public Wi-Fi hotspot)
If 67% of Internet users are more careful about personal information when using a public Wi-Fi, then 33% of them are not.P(none of the selected users is more careful about personal information when using a public Wi-Fi hotspot) = [tex]0.33^{3}[/tex] ≈ 0.036
P(at least one is more careful about personal information when using a public Wi-Fi hotspot) = 1 - 0.036 = 0.964

Answer:
Relational Database
Explanation:
Relational Database is the type of database in which data is stored and presented in the form of tables and it is used to access, manipulate and manage data.Table is also called a relation. It consists of rows and columns where rows represent a record of data and columns represent the attributes of the data.Every table has a primary key which uniquely identifies a row in a table and a foreign key is used to establish relationships among tables.In relational database domain is used to define specify the possible values that an attribute can have.Constraints can also be applied to the values of the attributes in the table.There are many advantages of a relational database. It can organize and manage bulk of information. It is easy to add or delete data in the relational database according to the change in requirements.Relational database ensures the consistency and integrity of data when many users obtain the same database at same time by using concurrency control methods.It ensures security by limiting access rights to the data.It also eliminates data redundancy and dependency using normalization technique which ensures data integrity and accuracy.One of the Visual Studio 2015 languages that can be used for rapid application development is C#.

A certain computer game is played between a human player and a computer-controlled player. Every time the computer-controlled player has a turn, the game runs slowly because the computer evaluates all potential moves and selects the best one. Which of the following best describes the possibility of improving the running speed of the game?A The game's running speed can only be improved if the game is played between two human players instead of with the computer-controlled player.B The game's running speed might be improved by using a process that finds approximate solutions every time the computer-controlled player has a turn.C The game's running speed cannot be improved because computers can only be programmed to find the best possible solution.D The game's running speed cannot be improved because the game is an example of an algorithm that does not run in a reasonable time.
Answer:
B The game's running speed might be improved by using a process that finds approximate solutions every time the computer-controlled player has a turn.
Explanation:
Even though the moves are not the perfect ones, the algorithm of the game can be written in a way that it can solve the problems and play faster.
Let's see the problems in other options.
A -> The only way is not replacing the computer with a human because, we know that computers can play faster than a human when the algorithm is written well.
C -> Computers cannot only be programmed to find the best possible solution. They can be programmed how the programmer wants them to behave.
D -> Since we do not know anything about the game, we cannot say anything about the algorithm runtime.

Answer:
d. it specifies the data types that can be used by .NET applications.
Explanation:
The .NET Framework Class Library (FCL) makes the system functionality of the .NET Framework available because it contains interfaces, data types, various classes and so on.
It is also important to note that the FCL is integrated to the CLR or Common Language Runtime of .NET Framework which is responsible for code execution.
The Framework Class Library or FCL can be categorized broadly into three:
1. Frameworks
2. Utility features in .NET, and
3. Wrappers around the Operating System (OS) functionality.
1. Frameworks: The FCL contains many frameworks aimed at the development of some applications. For instance, WPF or Windows Presentation Foundation is used to carry out a number of functions but majorly to render user interfaces.
2. Utility features in .NET: This contains a number of classes for use in the .NET framework, examples of these classes include: dictionary, queue, stack, list and so on. Additionally, it contains classes for different manipulations, for example, for handling regular expressions the Regex class is available for use.
3. Wrappers around the Operating System (OS) functionality: Contained in the Framework Class Library are wrappers that are present at the root functionality of the Windows OS. For instance, classes to handle I/O, network features, file system as so on.

Which benefit will implementing the Spanning Tree Protocol provide to this design?
Answer:
Redundant paths can be available without causing logical Layer 2 loops.
Explanation:
Spanning Tree Protocol is used to allow redundancy in the Layer 2 switched networks without creating cycles/circles also called loops. These loops are called physical loops. When two parts of the switched network are connected via two or more Layer 2 switches this result in a loop. This affects the performance of the network as the result of broadcast packets flooding. STP puts one port of the switch to forward mode and the rest of the ports within the same part of the network to the blocking mode to avoid broadcast packet flooding. STP puts all the ports that are allowing redundant paths to block mode and the one port that is left after this is placed in forward mode.Spanning Tree Algorithm is used by STP to determine the optimal path of switch to the network.Bridge Protocol Data Units are used to share the information about the optimal path determined by the spanning tree algorithm with other switches.This information helps STP to eliminate the redundant paths.So this is how STP tracks all the links in the switched network and eliminates redundant loops by allowing only one active path to the destination while blocking all other paths.A city-wide wireless network is an example of which type of network?

Although the traditional model of software acquisition still accounts for more software acquisition, a new model, called ________, is changing the picture dramatically.A. Hardware as a HelpB. Software as a ServiceC. Processing as a ProductD. Storage as a Solution
Answer:
Option B Software as a Service
Explanation:
Software as a Service (SaaS) is a new software acquisition model. SaaS is based on a subscription license instead of perpetual license. The software is hosted by software provider and the user is required to use a client software or web browser to access and use the software. User pays for the service (software itself) they use on regular basis which can be monthly or yearly.
SaaS offers always up-to-date software solution to the user and the software can be accessed from any machine at any place. Apart from the subscription fee, user is not required to pay additional cost for license renewal or updating software. SaaS provides a cheaper and economic cost of software acquisition.

What is the output of the code snippet given below?string s = "abcde";int i = 1;while (i < 5){ cout << s.substr (i, 1); i++;}a. no outputb. abcdc. abcde d. bcde
Answer:
The answer is "Option d".
Explanation:
In the given C++ program code, two-variable is defined, that is "s and i", in which variable s is a string type that holds a value, that is "abcde", and variable i is an integer type, that holds a value '1'.
In the next line, a while loop is declared, that uses integer variable which value is less than 5, inside a loop a substring function is used, that specifies the number of character and return its value. In array and string indexing starts from 0, and that variable i starts from 1, that is used in substring function, that's why it will print only "bcde".Why are models based on assumptions? A. Because models are not intended to analyze real-world events. B. Because models are only concerned about questions of equity, not question of efficiency. C. Because models have to be simplified to be useful. D. Because models are very different from theories.
Models are based on assumptions because models have to be simplified to be useful.
Answer: Option C.
Explanation:
Model is a computer program which helps to predict the situation as to what might have happened. Models are used almost in every aspect, be it economics or science or biology.
Assumptions are necessary because there are many complexity in every system and it is thus essential to have an understanding of the working of those system. It is necessary to remove the complexities for models to be useful. Models which aren’t based on assumptions are massive which is turn creates a problem. Thus it is necessary that models are simplified to be useful.
