Let L be the set of exactly those strings over the alphabet \Sigma = {a, b, c, g}, that satisfy all of the following properties: the length of the string is equal to 5n+3, for some natural number n greater or equal than 0; all of the first (leftmost) 2n symbols are elements of the set {b, c, g}; all of the last (rightmost) 3n symbols are elements of the set {a, b}; the symbols at position 2n+1, 2n+2, and 2n+3 (from the left, i.e., after the first 2n symbols but before the last 3n symbols) are elements of the set {c, g}; Write a complete formal definition of a context free grammar that generates L. If such a context free grammar does not exist, state that the context free grammar does not exist, and prove it.

B. Data Base Management System

Explanation:

A database management system (DBMS) can be defined as a collection of software applications that typically enables computer users to effectively and efficiently create, store, modify, retrieve, centralize and manage data or informations in a database. Generally, it allows computer users to efficiently retrieve and manage their data with an appropriate level of security.

Generally, a database management system (DBMS) acts as an intermediary between the physical data files stored on a computer system and any software application or program.

A data dictionary can be defined as a centralized collection of information on a specific data such as attributes, names, fields and definitions that are being used in a computer database system.

In a data dictionary, data elements are combined into records, which are meaningful combinations of data elements that are included in data flows or retained in data stores.

This ultimately implies that, a data dictionary found in a computer database system typically contains the records about all the data elements (objects) such as data relationships with other elements, ownership, type, size, primary keys etc. This records are stored and communicated to other data when required or needed.

Hence, a software that enables the organization to centralize data, manage the data efficiently while providing authorized users a significant level of access to the stored data, is called a Data Base Management System (DBMS).

Answer:

The statement about Multiprocessors that is FALSE is:

a. Asymmetric multiprocessors are a popular form of tightly coupled architecture

Explanation:

Symmetric multiprocessors house two or more identical processors sharing a single main memory.  The multiprocessors are tightly coupled, and all of them can access all the connected devices without any preferential treatment of one over the others.  This is unlike asymmetric multiprocessors that do not share a single main memory.   Instead, they have distributed memories.

Answer:

Explanation:

There are many weaknesses/vulnerabilities, some of which are the following...

Default Network Hardware, many individuals will go out and buy a new router and install it in their home. These devices come with a preset configuration including a preset security password which is many times a default password used for every router of the same model. This can be easily obtained by anyone who can then access the network.

Access Point hacking, an experienced individual can use a packet sniffer to detect the SSID that is frequently sent from the router in order to create an access point to be able to access the network.

WEP encryption is another vulnerability. These are very low security passwords that can be cracked using different software in a short period of time.

These are some of many vulnerabilities that wireless local networks have, but there are also many precautions and security measures that can be taken to prevent them.

Answer:

the answer for the question is B

The network performance is said to be biased when it performs poorly on train set.

A measurement regarding service or the state of quality of network received by the consumer is known as network performance. Operators can control the upper limit of a network performance.

When network operators or service providers put a cap and lower the speed of a network on a train set, it is said to be a biased network performance.

Hence, option B holds true regarding network performance.

Your answer is outline.

An outline is the tool that will help you the most when developing the content you will use in your presentation.

A presentation is a method of communicating information from a speaker to an audience.

Presentations are usually demonstrations, introductions, lectures, or speeches intended to inform, persuade, inspire, motivate, build goodwill, or introduce a new idea/product.

An outline is a list of the main topics and subtopics that you intend to cover in your presentation in a hierarchical order.

It can assist you in ensuring that your ideas flow logically and that no important points are overlooked.

A storyboard, on the other hand, is a visual representation of your presentation that shows the order of your slides, the images or videos you intend to use, and the text that will go with them.

Answer:

Predictive validity.

Explanation:

A correlation can be defined as a numerical measure of the relationship existing between two variables (x and y).

In Mathematics and Statistics, a group of data can either be negatively correlated, positively correlated or not correlated at all.

1. For a negative correlation: a set of values in a data increases, when the other set begins to decrease. Here, the correlation coefficient is less than zero (0).

2. For a positive correlation: a set of values in a data increases, when the other set also increases. Here, the correlation coefficient is greater than zero (0).

3. For no or zero correlation: a set of values in a data has no effect on the other set. Here, the correlation coefficient is equal to zero (0).

A predictive validity can be defined as a measure of the extent to which a test score on a scale is able to predict scores based on certain criteria. Thus, it's a measure of the degree to which a certain criteria can predict future behavior or performance.

One of the most common area in which predictive validity is used is in university or college admissions such as in how scores on an assessment or test are related to performance based on a standard or criterion.

In this scenario, there exists a statistical relationship between the results of the assessment conducted and number of students who were successful. Thus, this will best indicate that the assessment has predictive validity.

The program in Python is as follows:

total = 0

count = 0

for i in range(8):

   num = float(input())

   if num < 10.5:

       total+=num

       count+=1

print("Average: ",total/count)

Explanation:

This initializes the total to 0

total = 0

This initializes the count to 0

count = 0

This loop is executed 8 times

for i in range(8):

This request for float number

   num = float(input())

If input is less than 10.5

   if num < 10.5:

The sum is taken

       total+=num

And count is incremented by 1

       count+=1

The loop ends here

This calculates and prints the average

print("Average: ",total/count)

#include <iostream>//header file

using namespace std;

void find_min(int x,int y)//defining a method find_min that takes two parameters

{

   if(x<y)//use if to check x less than y

   {

       cout<<x;//print value x

   }

   else//else block

   {

       cout<<y;//print value y

   }

}

int main()//main method

{

   int x,y;//defining integer variable

   cout<<"Enter first number: ";//print message

   cin>>x;//input value

   cout<<"Enter second number: ";//print message

   cin>>y;//input value

   find_min(x,y);//calling method

   return 0;

}

Output:

Enter first number: 4  

Enter second number: 2

Explanation:

In this code, a method "find_min" that takes two integer variable "x,y" in its parameters and use if block to check its value and print is value.

In the main method, we declared two integer variable "x,y" that takes value from user-end, and pass the value into the method that prints its calculated value.
