Correct option is C) No, they don’t.

Given:

Number = 1671

Concept used:

The remainder can be added in the same way as the actual number when divided by any other number

Ex- 25/4 = (24 + 1)/4 = (24/4 + 1/4) = 0 + 1 = 1, Remainder = 1

Calculation:

1671 is divided by 64

⇒ 1671/64

⇒ (1600 + 64 + 7)/64

⇒ 1600/64 + 64/64 + 7/64

Remainder = 0 + 0 + 7 = 7

∴ The required remainder is 7

2. Cyber security is one of the most urgent issues of the day. Computer networks have always been the target of criminals, and it is likely that the danger of cyber security breaches will only increase in the future as these networks expand, but there are sensible precautions that organizations can take to minimize losses from those who seek to do harm.

3. Cybercrime is any unlawful activity that involves a computer. Cybercrime is defined as a crime in which a computer is the object of the crime (hacking, phishing, spamming) or is used as a tool to commit an offense (child pornography, hate crimes). 

4. Live example of cyber crime are Hacking of google account, Hacking of facebook account.

5. Some common cyber security threats are:

Hacking

Hacking is a term used to describe actions taken by someone to gain unauthorized access to a computer. The availability of information online on the tools, techniques, and malware makes it easier for even non-technical people to undertake malicious activities.

Malware

Malware is one of the more common ways to infiltrate or damage your computer.

Pharming

Pharming is a common type of online fraud.

Phishing

Phishing is used most often by cyber criminals because it's easy to execute and can produce the results they're looking for with very little effort.

Ransomware

Ransomware is a type of malware that restricts access to your computer or your files and displays a message that demands payment in order for the restriction to be removed. The two most common means of infection appear to be phishing emails that contain malicious attachments and website pop-up advertisements.

Spam

Spam is one of the more common methods of both sending information out and collecting it from unsuspecting people.

Spoofing

This technique is often used in conjunction with phishing in an attempt to steal your information. 

Spyware

Spyware & Adware

Spyware and adware are often used by third parties to infiltrate your computer.

Trojan Horses

A Trojan horse may not be a term you're familiar with, but there's a good chance you or someone you know has been affected by one.

The features of UNIX operating system are

1. multi-tasking: more than one program can be run at a time.

2. Machine-independence: The System hides the machine architecture from the user, making it easier to write applications that can run on micros, mini and mainframe computers.

3. Multi-User Operations: UNIX is a multi-user system designed to support a group of users simultaneously. The system allows for the sharing of processing power and peripheral resources, white at the same time providing excellent security features.

The features of the UNIX operating system are:

1. Multi-tasking:

More than one program can be run at a time

2. Portability:

Only the kernel (<10%) is written in assembler tools for program development a wide range of support tools (debuggers, compilers). The system is written in high-level language making it easier to read, understand, changed and, therefore move to other machines.

3. Machine-independence: 

The System hides the machine architecture from the user, making it easier to write applications that can run on micros, mins, and mainframes.

4. Multi-User Operations:

UNIX is a multi-user system designed to support a group of users simultaneously. The system allows for the sharing of processing power and peripheral resources, while at the same time providing excellent security features.

5. Hierarchical File System:

UNIX uses a hierarchical file structure to store information. This structure has the maximum flexibility in grouping information in a way that reflects its natural state. It allows for easy maintenance and efficient implementation.

A ‘while’ loop statement repeatedly executes a statement or sequence of statements written in the flower brackets as long as a given condition returns the value ‘true’.

Syntax:

The syntax of a ‘while’ loop in C++ is:

while(condition)

{

statement (s) ;

}

Here the condition may be any expression, and for true is any non zero value. The loop iterates while the condition is true. When the condition becomes false, program control passes to the line immediately following the loop. During the first attempt, when the condition is tested and the result is false, the loop body will be skipped and the first statement after the ‘while’ loop will be executed.

Example:

#include<iostream>

int main()

{

int a = 10;

while(a<15)

{

cout<<"value of a:"<<a<<endl;

a++;

}

return  0;

}

When the above code is executed, it produces the following result:

value of a: 10

value of a: 11

value of a: 12

value of a: 13

value of a: 14

1. a cos() function:

It is a mathematical function that returns the arc cosine value for the given argument. The argument value must be in the range -1 to 1, otherwise, a domain error is triggered.

Syntax: float acos ( float arg);

2. cos() function:

It is a mathematical function that returns the cosine Value for the given radians.

Syntax: float cos( float arg );

3. cell() function: It is a mathematical function that returns the smallest integer value that is not less than the specified number. In other words, it returns the Round-Up value of a given number.

Syntax: float cell( float num);

4. exp() function:

It is a mathematical function that returns the natural logarithm base “e” raised to the power equal to the argument.

Syntax: float exp( float num);

5. sqrt() function:

It is a mathematical function that returns the square root of the given “num” value.

Syntax: float sqrt( float num);

Enables user to use many USB devices simultaneously.

Array is a group of similar elements that share a common name.

1. Input Operator:

The statement cin>>num; is an input statement and causes the program to wait for the user to type in a number. The operator >>is known as extraction or get from the operator. It takes the value from the keyboard and assigns it to the variable on its right.

2. Output Operator: 

The statement cout<< “ the numbers”;uses the cout identifier that represents the standard output stream (screen) in C++. The operator < – Sounds incomplete -Author.

The accessing of data of the members is done by using the following format:

structure variable.member name for example cin>>s1.rollno>>s1.age>>s1.name>>s1.marks;

An input device is a piece of equipment used to provide data and control signals to an information processing system, such as a computer or information appliance. Examples of input devices include keyboards, mouse, scanners, cameras, joysticks, and microphones.
