What is the time period of 1st generation of computer ???

Consists of forging the return address on an email so that the message appears to come from someone other than the actual sender

Pavlova-9 [17]

Answer:

C. Spoofing.

Explanation:

Cyber security can be defined as preventive practice of protecting computers, software programs, electronic devices, networks, servers and data from potential theft, attack, damage, or unauthorized access by using a body of technology, frameworks, processes and network engineers.

Some examples of cyber attacks are phishing, zero-day exploits, denial of service, man in the middle, cryptojacking, malware, SQL injection, spoofing etc.

Spoofing can be defined as a type of cyber attack which typically involves the deceptive creation of packets from an unknown or false source (IP address), as though it is from a known and trusted source. Thus, spoofing is mainly used for the impersonation of computer systems on a network.

Basically, the computer of an attacker or a hacker assumes false internet address during a spoofing attack so as to gain an unauthorized access to a network.

One lap around a standard high-school running track is exactly 0.25 miles. Write a program that takes a number of miles as input

salantis [7]

Answer:

import java.util.Scanner;

public class Miles {

public static void main(String[] args) {

//initialization

double Number_Miles;

//print the message

System.out.print("Enter the number of miles: ");

Scanner scn1 = new Scanner(System.in);

Number_Miles = scn1.nextDouble(); //read the input from user

//calculate the laps

double yourValue = Number_Miles/0.25;

//display the output on the screen

System.out.printf("%.2f", yourValue);

}

Explanation:

First import the library Scanner than create the class and define the main function. In the main function, declare the variables.

print the message on the screen and then store the value enter by the user into the variable.

Scanner is a class that is used for reading the output. So, we make the object of the class Scanner and then object call the function nextDouble() which reads the input and store in the variable.

After that, calculate the number of laps by dividing the number of miles with the given one lap running track value (0.25 miles).

$Number\,of\,laps = \frac{Number\,of\,miles}{0.25}$

the output is stored in the variable.

After that, print the value on the screen with 2 digits after the decimal point.

we can use "%.2f" in the printing function in java.

like System.out.printf("%.2f", output);

Convert the following Base 10 (decimal) numbers to base 2(binary): 107 200

melamori03 [73]

Answer:

107₁₀ - 1101011

₂ (Binary representation)

200₁₀- 11001000₂ (Binary representation)

Explanation:

Converting from Decimal to binary:

Procedure -

1. Divide the number by 2, write the reminder separately.

2. Divide the divisor by 2, write the reminder before the previously written reminders.

Keep doing this till you get your divisor as 1.

Then we will write the divisor before the written reminders and that will be the binary representation.

For 107 :

We divide 107 by 2 ,we get the divisor 53 and remainder 1

( 1 )

Then,we will divide this divisor i.e 53 by 2,we get divisor 26 and remainder 1 ,we will put this remainder before the previous one.

( 1 1 )

Then,we will divide this divisor i.e 26 by 2,we get divisor 13 and remainder 0 ,we will put this remainder before the previous one.

( 0 1 1 )

Then,we will divide this divisor i.e 13 by 2,we get divisor 6 and remainder 1 ,we will put this remainder before the previous one.

( 1 0 1 1 )

Then,we will divide this divisor i.e 6 by 2,we get divisor 3 and remainder 0,we will put this remainder before the previous one.

( 0 1 0 1 1 )

Then,we will divide this divisor i.e 3 by 2,we get divisor 1 and remainder 1 ,we will put this remainder before the previous one.

( 1 0 1 0 1 1 )

As we get the divisor=1,then we will stop.we will write the divisor before the written reminders.

( 1 1 0 1 0 1 1 )

This will be the binary representation of 107.

For 200 :

We divide 200 by 2 ,we get the divisor 100 and remainder 0

( 0 )

Then,we will divide this divisor i.e 100 by 2,we get divisor 50 and remainder 0 ,we will put this remainder before the previous one.

( 0 0 )

Then,we will divide this divisor i.e 50 by 2,we get divisor 25 and remainder 0 ,we will put this remainder before the previous one.

( 0 0 0 )

Then,we will divide this divisor i.e 25 by 2,we get divisor 12 and remainder 1 ,we will put this remainder before the previous one.

( 1 0 0 0 )

Then,we will divide this divisor i.e 12 by 2,we get divisor 6 and remainder 0 ,we will put this remainder before the previous one.

( 0 1 0 0 0 )

Then,we will divide this divisor i.e 6 by 2,we get divisor 3 and remainder 0 ,we will put this remainder before the previous one.

( 0 0 1 0 0 0 )

Then,we will divide this divisor i.e 3 by 2,we get divisor 1 and remainder 1,we will put this remainder before the previous one.

( 1 0 0 1 0 0 0 )

As we get the divisor=1,then we will stop.we will write the divisor before the written reminders.

( 1 1 0 0 1 0 0 0 )

This will be the binary representation of 200.

Why are some geo satellites not usually used for transmitting tcp/ip information?

charle [14.2K]

TCP has flow control, which means a two-way connection must be present. Satellites are sometimes optimized for broadcasts, which is unidirectional (ie., sending, not receiving).
