True or false: In relational databases, each individual space within a row or column contains exactly one value.
Answer:
True.
Explanation:
A database management system (DBMS) can be defined as a collection of software applications that typically enables computer users to create, store, modify, retrieve 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.
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.
Basically, when a database management system (DBMS) receives data update requests from application programs, it simply instructs the operating system installed on a server to provide the requested data or informations.
A relational database can be defined as a type of database that is structured in a manner that there exists a relationship between its elements.
Hence, in relational databases, each individual space within a row or column contains exactly one value.

Adam is writing a program that: 1) has the user guess a number, and 2) tells the user how many guesses it took to get the correct answer. But when Adam tests the program, it always outputs that it took the user one guess, even when it takes many guesses. What error did Adam most likely make, and how should it be fixed? The difference between a for loop and a while loop is that a for loop is a loop that happens for a certain number of times. A while loop happens until a certain condition is met. How do you know when to use each one? Give specific examples in your answer. What are some programs that you have used that have condition-controlled loops and count-controlled loops? Why is it important that if, elif, and else statements appear in the proper order? What are some situations where you might find it useful to use the “!” symbol in a program?
Answer:
There are two ways in which programs ... count-controlled loops; condition-controlled loops ... Sometimes it is necessary for steps to iterate a specific number of times. ... A count-controlled loop is used when the number of iterations to occur is ... the variable 'count' is used to keep track of how many times the algorithm
Explanation:
Answer:
Adam most likely forgot to add a while loop to the guessing code or didn’t add it properly, meaning that instead of letting him guess multiple times it just continues the code, all he needs to do is add a while loop to fix the line of code.

How to format each dictionary item as a text string in the input file. How to covert each input string into a dictionary item. How to format each item of your inverted dictionary as a text string in the output file.
Answer:
- To get the items of a dictionary and print them as a string, use the items() method to unpack the keys and values in a for and print or write them into a file.
for key, value in mydict.items():
print(f"{key}, {value}")
- To convert string from user input into dictionary;
mystring = input().split(" ") #assuming the words are separated by a space.
from word in mystring:
mydict[word] = mydict.get(word, 0) + 1
This would use the words in the string as the keys of the dictionary and the count of each word as the respective values.
Explanation:
A dictionary is a data structure in python used to store data in key-value pairs. The items are enclosed in curly braces and can be accessed with the key in dot or bracket notation.
Dictionaries in Python are used to represent data items in pairs; i.e. key and values
(a) Format items as strings in an input file
To do this we make use of the file manipulation.

Describe the action of the indexOf and substring methods. Explain how these methods can be used to divide an existing string into two parts. Why is it necessary to add 1 to the position of the space when copying the remainder of the string
Answer:
The indexOf is a string method used to get the index of a character in a string. It can be used with the slice, substr, or subString methods to divide a string into two or more parts.
var words = "hello John Snow";
var A = words.slice(0, words.indexOf("John"));
var B = words.slice(words.indexOf("John") + 1, words.length());
One (1) is added to the space of avoid repeating a character in both new strings.
Explanation:
The indexOf method is a built-in method in Javascript used to get the index of a character or word in a string variable. The return integer number can be used in a method like a slice() to divide the string and them to other string variables.
What does a wireless LAN (WLAN) act as to a wired network?
a. Gateway
b. Bridge
c. Switch
d. Router
Answer:
The answer is option A "Gateway"
Explanation:
A wireless LAN (WLAN) connects at least two computers or devices using some wireless distribution technique (normally spread-spectrum or OFDM radio), and as a rule gives a connection through a gateway/modem to the more extensive Web. This gives clients the portability to move around through a local coverage and still be connected with the network.
Wireless LANs have gotten famous in the home because of simplicity of establishment, the expanding ubiquity of PC and hand-held PCs, and commonality, due the accessibility of (frequently free) wireless network on schools and in open organizations.
A WLAN, or wireless LAN, is a network that permits gadgets to connect and communicate wirelessly. Dissimilar to a traditional wired LAN, in which gadgets communicate over Ethernet links, devices on a WLAN connects by means of Wi-Fi. They can speak with different gadgets on the network a similar way they would on a wired network.
The essential contrast is the way the information is communicated. In a LAN, information is communicated over actual links or cables in a progression of Ethernet packets. In a WLAN, bundles are communicated over the air.

Authorized agent Confidentiality Integrity Encryption 6:53 PM ______ means that only people with the right permission can access and use information.
Answer:
The answer is "Confidentiality"
Explanation:
Confidentiality alludes to shielding data from being gotten to by unapproved parties. All in all, solitary the individuals who are approved to do so can access delicate information. Imagine your bank records, You ought to have the option to get to them obviously, and representatives at the bank who are assisting you with an exchange ought to have the option to get to them, yet nobody else ought to. An inability to keep up Confidentiality implies that somebody who shouldn't have access has figured out how to get it, through deliberate act or coincidentally. Such a disappointment of Confidentiality, normally known as a breach can't be helped. When the secret has been uncovered, it is highly unlikely to un-uncover it.
Assuming your bank records are posted on a public site, everybody can realize your bank account number, balance, and so forth, and that data can't be eradicated from their brains, papers, PCs, and different spots. Virtually all the significant security occurrences reported in the media today include loss of Confidentiality.
Thus, in summary, a breach of Confidentiality implies that somebody accesses data who shouldn't be permitted to.

What is the output of the following program
#include
int toronto (int x)
{
int w;
if (x == 0) w = 1; else w = toronto (x-1);
return (w);
}
int main (void)
{
int a = 2;
printf ("%d", toronto (a));
return (0); }
a. 0
b. 1
c. 2
d. -1
e. none of these
Answer:
The output is 1
Explanation:
Analysing the flow of program (We start from the main method)
The main begins here
int main (void) {
This line declares a as integer and also initializes it to 2
int a = 2;
This line passes 2 to the function names toronto and also prints the result of the function
printf ("%d", toronto (a));
return (0); }
The toronto function begins here.
Note that the function receives 2 as its argument and this is saved in variable x
int toronto (int x) {
This declares w as integer
int w;
If x is 0, w equals 1
if (x == 0) w = 1;
If otherwise
else
This reduces x by 1 and performs a recursion
w = toronto (x-1);
return (w);
}
Because of the structure of the if condition in the toronto function, the function will be repeated until x is 0.
And when x = 0; w = 1
This returns w (i.e. 1) back to the main function where 1 is printed as the output
return (w);

In other to ensure that ;
Lower digit is written first ; (a < b) ;
Only odd numbers are considered,
a%2 == 1 ; b%2 == 1 (remainder when a and b are divided by 2 is 1.
Both a and b are declared as a tuple in other to obtain a pair of odd values.
