What are the different types database of end users? Discuss the main activi-ties of each
Answer:
following types of databases available in the market −
Centralised database.
Distributed database.
Personal database.
End-user database.
Commercial database.
NoSQL database.
Operational database.
Relational database.
Cloud database.
Object-oriented database.
Graph database
Answer:
1. Casual End Users
These are the users who occasionally access the database but they require different information each time. They use a sophisticated database query language basically to specify their request and are typically middle or level managers or other occasional browsers. These users learn very few facilities that they may use repeatedly from the multiple facilities provided by DBMS to access it.
2. Naive or parametric end users
These are the users who basically make up a sizeable portion of database end users. The main job function revolves basically around constantly querying and updating the database for this we basically use a standard type of query known as canned transaction that have been programmed and tested. These users need to learn very little about the facilities provided by the DBMS they basically have to understand the users’ interfaces of the standard transaction designed and implemented for their use. The following tasks are basically performed by Naive end users:
The person who is working in the bank will basically tell us the account balance and post-withdrawal and deposits.
Reservation clerks for airlines, railway, hotels, and car rental companies basically check availability for a given request and make the reservation.
Clerks who are working at receiving end for shipping companies enter the package identifies via barcodes and descriptive information through buttons to update a central database of received and in transit packages.
3. Sophisticated end users
These users basically include engineers, scientist, business analytics and others who thoroughly familiarize themselves with the facilities of the DBMS in order to implement their application to meet their complex requirement. These users try to learn most of the DBMS facilities in order to achieve their complex requirements.
4. Standalone users
These are those users whose job is basically to maintain personal databases by using a ready-made program package that provides easy to use menu-based or graphics-based interfaces, An example is the user of a tax package that basically stores a variety of personal financial data of tax purposes. These users become very proficient in using a specific software package.

in theory a hacker with a small but powerful directional antenna could access a wireless network from more than one mile away. In a real-world situation what is the more likely range involved?
A directional antenna or beam that used as an antenna that radiates or receives additional power from the unwanted source into certain directions that enhances performance and reduces interference.
Receiver satellite TVs commonly employ parabolic antennas.It better pulls signals in one way in which it detects a weaker or more distant signal than an omnidirectional antenna counterpart.The difference is that they do it by reducing their ability to draw signals from other directions.The coverage area is smaller yet extends farther out. This could reach up to 8 miles under optimum conditions.Learn more:

Explanation:
Suppose that someone suggests the following way to confirm that the two of you are both in possession of the same secret key. You create a random bit string the length of the key, XOR it with the key, and send the result over the channel. Your partner XORs the incoming block with the key (which should be the same as your key) and sends it back. You check and if what you receive is your original random string, you have verified that your partner has the same secret key, yet neither of you has ever transmitted the key. Is there a flaw in this scheme?
Answer:
yes, there is a small flaw. You can reconstruct your partner's key even if it is different from yours.
Explanation:
Suppose you have key a and your partner has key b, you want to check if a == b, but if it is not, your partner doesn't want to reveal his key otherwise he could have just sent it.
So you create a random bit string r. and send a⊕r to him. He sends you back a⊕r⊕b. If a==b the a⊕b would cancel each other out, and you would be left with r.
However, if you calculate a⊕r⊕b⊕r⊕a, you would always get b! In other words, you XOR the received value with r and XOR it with your a. Then you get b, whatever it is.

Write a program that computes an integer's checksum. To compute the checksum, break the integer into its constituent digits and, working from right to left, doubling every second digit. If the product results in a number with two digits, treat those two digits independently. Then, sum all the digits for the final checksum.
Following are the C++ program to the given question:
#include <iostream>//header file
using namespace std;
int findCheckSum(int n)//defining a method findCheckSum that takes integer parameter
{
bool c = false;//defining bool variable
int S= 0,d;//defining integer variable
while(n)//defining while loop that seprates digits
{
d = n%10; // get the digit.
n=n/10; // remove the last digit.
if(c)//use if to check the even position value
{
d=d*2;//multiplying d with 2
while(d)//use if to check digit value
{
S=S+(d%10);//adding value
d=d/10;// remove the last digit.
}
}
else//defining else block
{
S=S+d;// checking the odd position
}
c= c^true;//holding bool value
}
return S;//return S
}
int main() //defining main method
{
cout << findCheckSum(1984);//calling method
}
Output:
22
Program Explanation:
Including header file.Defining a method, "findCheckSum" that takes an integer parameter "n".Inside the method, a bool variable "c" and two integer variable "S, d" is declared that defines a while loop.Inside the loop, a conditional statement is defined that separates digits and adds them into the "S" variable, and returns its values.Outside the method, the main method is declared that calls the "findCheckSum" method, and print its value.Learn more:

*****
Expected output
#####

Answer:
get_pattern()
get_pattern()
print(get_pattern())
print(get_pattern())
Explanation:
The program is given in Python; this means that it must be completed in Python.
The code segment that completes the program is:
print(get_pattern())
print(get_pattern())
From the complete question, the given code segment is:
def get_pattern():
return '*****'
The above function will only return 5 characters i.e. 5 *'s, but it will never print the characters.
For the characters to be printed, a print statement must be introduced when calling the function get_pattern()
So, the print statement will be:
print(get_pattern())
The question requires 10 characters; so, the print statement must be called twice.
Hence, the code segment that completes the program is:
print(get_pattern())
print(get_pattern())

What are Computer-Mediated Communications?The time and geographic limitations of in-person contact are removed through computer-mediated communication (CMC), in which people use computers and networks to communicate with one another across enormous distances and multiple time zones.
Computer-mediated communication (CMC) emphasizes how important it is for parties to communicate with one another through mediated channels of communication. Instead of focusing on the quantity, content, frequency, or timing of the message exchange, CMC places more emphasis on how new messages relate to older ones.
Therefore, the methods of computer-mediated communication that are used on a daily basis include audio, video, and instant messaging.
