Answer:
Someone can make a histogram instead of a bar chart if distributions of variables are need to be represented and if data is quantitative.
Explanation:
Histograms are drawn to represent distributions of variables whereas bar charts are used to compare various variables. Histograms plot quantitative data whereas bar charts plot categorical data.
So, someone can make a histogram instead of a bar chart if distributions of variables are needed to be represented and if data is quantitative.
Answer:
a) true.
Explanation:
Encryption is a form of cryptography and typically involves the process of converting or encoding informations in plaintext into a code, known as a ciphertext. Once, an information or data has been encrypted it can only be accessed and deciphered by an authorized user.
Some examples of encryption algorithms are 3DES, AES, RC4, RC5, and RSA.
On the other hand, authentication can be defined as the process of verifying the identity of an individual or electronic device. Authentication work based on the principle of matching an incoming request from a user or electronic device to a set of uniquely defined credentials.
Basically, authentication ensures a user is truly who he or she claims to be, as well as confirm that an electronic device is valid through the process of verification.
Digital certificates, smart cards, picture passwords, and biometrics are used to perform an authentication.
<em>Hence, in cybersecurity the use of encryption and authentication protocols is the standard method of countering attempts to alter or insert transmissions. </em>
The network layer is responsible for logical connection setup, data forwarding, routing & delivery. This therefore means that the network (third) layer of the OSI model is responsible for allowing one computer to share information with other computers.
Graphic images can be stored in a variety of formats including JPEG and GIF. Hope this helped!
Answer:
The control unit of the central processing unit regulates and integrates the operations of the computer. It selects and retrieves instructions from the main memory in proper sequence and interprets them so as to activate the other functional elements of the system at the appropriate moment
