Answer:
He was not born into a family of skilled laborers
Explanation:
It cannot be database programs because database programs can not
store and organize data.
create graphics.
communicate data.
alleviate information overload.
It cannot be spreadsheets because a spreadsheet or worksheet is a file made of rows and columns that help sort data, arrange data easily, and calculate numerical data. What makes a spreadsheet software program unique is its ability to calculate values using mathematical formulas and the data in cells.
It cannot be word processing tools because a word processor is software or a device that allows users to create, edit, and print documents. It enables you to write text, store it electronically, display it on a screen, modify it by entering commands and characters from the keyboard, and print it.
Therefore the answer is C. Web design programs.
Hope this helps.
There are two main types of encryption - <span>symmetric and asymmetric.
Using symmetric encryption, you use a single secret key that is used to both encrypt and decrypt the data. This form of encryption has been used way before computers! Without this key it is very hard to decrypt a message. However, the issue with this is that if you want to send an encrypted message, you also have to send a key to them, and </span>if your somebody unintended intercepts the
key, they can read the message.
What's the solution? Asymmetric cryptography or public key encryption. Asymmetric cryptography uses encryption that splits the key into two
smaller keys. One of the keys is public and one is kept private.
A good metaphor for understanding this is the public key is the lock, and the private key is the key. You can encrypt a message to send to somebody with their public key, locking it, which they can then decrypt, unlock, with their private key. And vice versa. So with this kind of encryption it's very difficult to decrypt a message for anybody but the owner as it's much harder to steal when it doesn't need to leave their computer, but easy to encrypt messages to send to them
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.
