You are concerned that if a private key is lost, all documents encrypted using your private key will be inaccessible. Which service should you use to solve this problem
Answer:
Key escrow.
Explanation:
Cyber security can be defined as preventive practice of protecting computers, software programs, electronic devices, networks, servers and data from potential theft, attack, damage, or unauthorized access by using a body of technology, frameworks, processes and network engineers.
In Cyber security, 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.
Typically, an information or data that has been encrypted can only be accessed and deciphered by an authorized user.
Hence, if a private key is lost, all documents encrypted using that private key will be inaccessible to the users. Thus, the service that can be used to solve this problem is a key escrow because the cryptographic (private) keys kept in an escrow system are protected and would not be released to anyone other than the original user (owner).
A key escrow can be defined as a data security method of storing very essential cryptographic keys.
Simply stated, key escrow involves a user entrusting his or her cryptographic key to a third party for storage.
As a standard, each cryptographic key stored or kept in an escrow system are directly linked to the respective users and are encrypted in order to prevent breach, theft or unauthorized access.
When a class implements in interface, it must ________ Group of answer choices overload all of the methods listed in the interface provide all of the nondefault methods that are listed in the interface, with the exact signatures and return types specified not have a constructor be an abstract class
Answer:
provide all of the nondefault methods that are listed in the interface, with the exact signatures and return types specified
Explanation:
I am assuming the programming language is Java. Actually, none of the answers are 100% correct, but this one is the only one that is partially correct. The reason is the class implementing an interface can be abstract, and in this case it may not provide ALL nondefault methods.

Explanation:
An input device can be defined as any device that is typically used for sending data to a computer system.
Generally, all of the output and input device of a computer are known as peripheral (external) devices and they provide data (informations) to the end users in various formats such as video, audio, texts, images etc.
Since input devices are peripheral (external) devices, they can be connected to the computer system wirelessly or through a wired-connection (cable).
Some examples of peripheral (external) devices are monitor, speakers, keyboard, printer, scanner, projector, mouse, etc.
A mouse is an input device that is designed and used to select specific menu options, drag and drop options and to draw something on screen.
You make a purchase at a local hardware store, but what you've bought is too big to take home in your car. For a small fee, you arrange to have the hardware store deliver your purchase for you. You pay for your purchase, plus the sales taxes, plus the fee. The taxes are 7.5% and the fee is $20. (i) Write a function t(x) for the total, after taxes, on the purchase amount x. Write another function f(x) for the total, including the delivery fee, on the purchase amount x. (ii) Calculate and interpret (f o t)(x) and (t o f )(x). Which results in a lower cost to you
Answer:
[tex]f(x) = 1.075x[/tex]
[tex]t(x) = x + 20[/tex]
[tex](f\ o\ t)(x) = 1.075x + 21.5[/tex]
[tex](t\ o\ f)(x) = 1.075x + 20[/tex]
Explanation:
Given
[tex]Tax = 7.5\%[/tex]
[tex]Fee = \$20[/tex] -- delivery
Solving (a): The function for total cost, after tax.
This is calculated as:
[tex]f(x) = Tax *(1 + x)[/tex]
Where:
[tex]x \to[/tex] total purchase
So, we have:
[tex]f(x) = x * (1 + 7.5\%)[/tex]
[tex]f(x) = x * (1 + 0.075)[/tex]
[tex]f(x) = x * 1.075[/tex]
[tex]f(x) = 1.075x[/tex]
Solving (b): Include the delivery fee
[tex]t(x) = x + Fee[/tex]
[tex]t(x) = x + 20[/tex]
Solving (c): (f o t)(x) and (t o f)(x)
[tex](f\ o\ t)(x) = f(t(x))[/tex]
We have:
[tex]f(x) = 1.075x[/tex]
So:
[tex]f(t(x)) = 1.075t(x)[/tex]
This gives:
[tex]f(t(x)) = 1.075*(x + 20)[/tex]
Expand
[tex]f(t(x)) = 1.075x + 21.5[/tex]
So:
[tex](f\ o\ t)(x) = 1.075x + 21.5[/tex]
[tex](t\ o\ f)(x) = t(f(x))[/tex]
We have:
[tex]t(x) = x + 20[/tex]
So:
[tex]t(f(x)) = f(x) + 20[/tex]
This gives:
[tex]t(f(x)) = 1.075x + 20[/tex]
We have:
[tex](f\ o\ t)(x) = 1.075x + 21.5[/tex] ---- This represents the function to pay tax on the item and on the delivery
[tex](t\ o\ f)(x) = 1.075x + 20[/tex] --- This represents the function to pay tax on the item only
The x coefficients in both equations are equal.
So, we compare the constants
[tex]20 < 21.5[/tex] means that (t o f)(x) has a lower cost

A computer that supports LoJack technology must have two main components installed. It needs an Application Agent (residing in the OS), which sends tracking signals that enable location and recovery of a stolen device. The other component is a Persistence Module, which restores the Application Agent and allows it to survive reinstallation of an operating system or reformatting of the hard drive. The highest level of security offered by LoJack can be achieved when Persistence Module resides in the:
Answer: Computer's BIOS
Explanation:
Following the information given in the question, the highest level of security that is offered by LoJack can be achieved when Persistence Module resides in the computer's BIOS.
