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>
Answer:
4. Command line interface (CLI)
Explanation:
An operating system is a system software pre-installed on a computing device to manage or control software application, computer hardware and user processes.
This ultimately implies that, an operating system acts as an interface or intermediary between the computer end user and the hardware portion of the computer system (computer hardware) in the processing and execution of instructions.
Some examples of an operating system on computers are QNX, Linux, OpenVMS, MacOS, Microsoft windows, IBM, Solaris, VM etc.
A Command line interface (CLI) refers to a text-based user interface that allow users to operate a software application or program, as well as manage and execute operating system functions by typing standard line of commands into the text-based user interface with a real-time response.
Basically, the CLI is solely text-based and as such requires a thorough knowledge and understanding of global commands, as well as administrative privileges in some cases.
<em>Hence, the operating system function which has a steeper learning curve (more difficult to learn) and can potentially break the system without careful use of its operations is the Command line interface (CLI). </em>
Answer:
Most likely C
Explanation:
Blueprint is the plan so she makes it 1st.
Building the roof is after the deck.
The deck is after the blueprint.
After it's all done she looks at it and thinks about what went wrong at then end.
If there are no mistakes it's B.
Hope this answers your question :).
