As we have seen in this chapter, public-key cryptography can be used for encryption and key exchange. Furthermore, it has some p

roperties (such as nonrepudiation) which are not offered by secret key cryptography. So why do we still use symmetric cryptography in current applications?

Answer:

Disadvantages of public key cryptography is that : Assymetric cryptography is slower than the private key cryptography.

Explanation:

We are dealing with big data applications most of time. Almost all applications are data intensive. Private key cryptography which is also known as symmetric cryptography. Symmetric cryptography based systems are faster. Since there is no key transmitted with the data, encrypted data can be transferred over the channel or session even if the path is vulnerable or have chances of interception as the chances of decrypting the data is almost impossible.

Also, The identity of the receiver is guaranteed using the password based authentication used by symmetric crypto systems. Only the trusted receiver who has the access to the secret key can only decrypt the payload

Public Key Cryptography is slower than private key cryptography. Today’s application’s are data intensive. In case of data intensive applications , encrypting huge data will take a lot more time than that of symmetric key cryptography. Whenever Bulk data transmission is needed symmetric key cryptography is preferred. Secret key based crypto systems have proven to be more faster than any currently available assymetric key based crypto systems.

explain the joke, “There are 10 types of people in the world: those who understand binary and those who don’t.”
tino4ka555 [31]

Answer:

Binary is made up of only 2 digits: a one and a zero. 1011 is eleven in our counting system.

So 10 in binary = 2 in our counting system.

Read the joke as follows. There are 2 types of people in the world: those who  understand binary and those who do not.

I guess it's not really that funny, but computer programmers like it.

How can i change ip address <br>​
JulijaS [17]

I believe your answer would be:

1: Open the command prompt window. Do this by clicking the "Start" button, and then selecting "Run." In the window that appears, type "cmd" into the text box and click the "OK" button.

2: Release the computer's current IP address. To do this, type "ipconfig /release" into the command prompt window and press Enter.

3: Acquire a new IP address. Do this by typing "ipconfig /renew" into the command prompt window and pressing Enter. This should assign the computer a new IP address, which will be different from the previous address.

4: Cycle your modem's power. If the above steps don't work, you can try renewing your IP address by cycling your modem's power. Turn off both your computer and your modem (and your router, if you have one). Wait at least 5 minutes, then turn everything back on. If your computer is set to receive an IP address dynamically (the most likely configuration), you should be assigned a new IP address automatically.

5: Check to make sure your IP address has changed. To do this, you can log on to a number of different websites that tell you your IP address.

Hope I helped, if so may I get brainliest and a thanks?

Thank you, Have a good day! =)

What was the impetus for corporations to begin entertainment broadcasting on radio?
Sladkaya [172]

To help radio operators on ships stay awake was the impetus for corporations to begin entertainment broadcasting on radio.

e. to help radio operators on ships stay awake

<u>Explanation:</u>

The principal radio station ever on the planet's history was made by Reginald Fessenden on Christmas Eve in 1906 when he radiated a "Christmas show" to the bewildered teams of the boats of the United Fruit Company out in the Atlantic Ocean and the Caribbean Sea.

The main voice and music signals heard over radio waves were transmitted in December 1906 from Brant Rock, Massachusetts (only south of Boston), when Canadian experimenter Reginald Fessenden delivered about an hour of talk and music for specialized onlookers and any radio beginners who may be tuning in.

Radio turned into another type of correspondence and amusement. Between the 1920s and 1950s many radio shows were communicated, and assembling around the radio at night was a typical type of diversion.
