Answer:
888 + 88 + 8 + 8 + 8 = 1000
Explanation:
Required
Add up to 1000 using only digit 8
There is no straight way to answer this question; so, we make use of trial by error method to arrive at our solution.
After several trials, I found out that:
888 + 88 + 8 + 8 + 8 = 1000
Answer:
1. open the software
2. select a new blank database or database wizard
3. name the database
4. enter field names and select the type of field (text, number, date, currency)
5. make one of the fields the primary key
6. click done, or save and close
7. open the table and add records
Answer: Identifying sequences
Explanation:
Since the user wants to know if there are any particular activities that the customers engage in, or the types of purchases made in the month before or after purchasing select items from your store, therefore, the data mining software can be used in identifying sequences.
In this case, the data mining software can't be used in classifying data whether into structured or unstructured data. Furthermore, the identification of clusters and associations aren't the correct answers.
Therefore, the best option is B.
I wouldn't see anything, because my computer does not use any network adaptors.
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.
