I an not sure what you want me to do so I am going to help you on both of these problems:
Question 2 answer: I think the answer is University/industry interaction
Question #3 answer: I think the answer for this is clearly written in the question (i think that the second answer choice is it)
I am not sure what this is but i am only in the 10th grade!!!! the only class that I took last year was Computer Fundumentals
Btw I am in K12 as well :)
Answer:
The fundamental limitation of symmetric (secret key) encryption is ... how do two parties (we may as well assume they are Alice and Bob) agree on a key? In order for Alice and Bob to communicate securely they need to agree on a secret key. In order to agree on a secret key, they need to be able to communicate securely. In terms of the pillars of IA, To provide CONFIDENTIALITY, a secret key must first be shared. But to initially share the key, you must already have CONFIDENTIALITY. It's a whole chicken-and-egg problem.
This problem is especially common in the digital age. We constantly end up at websites with whom we decide we want to communicate securely (like online stores) but with whom we there is not really an option to communicate "offline" to agree on some kind of secret key. In fact, it's usually all done automatically browser-to-server, and for the browser and server there's not even a concept of "offline" — they only exist online. We need to be able to establish secure communications over an insecure channel. Symmetric (secret key) encryption can't do this for us.
Asymmetric (Public-key) Encryption
Yet one more reason I'm barred from speaking at crypto conferences.
xkcd.com/177/In asymmetric (public key) cryptography, both communicating parties (i.e. both Alice and Bob) have two keys of their own — just to be clear, that's four keys total. Each party has their own public key, which they share with the world, and their own private key which they ... well, which they keep private, of course but, more than that, which they keep as a closely guarded secret. The magic of public key cryptography is that a message encrypted with the public key can only be decrypted with the private key. Alice will encrypt her message with Bob's public key, and even though Eve knows she used Bob's public key, and even though Eve knows Bob's public key herself, she is unable to decrypt the message. Only Bob, using his secret key, can decrypt the message ... assuming he's kept it secret, of course.
Explanation:
A. modem or d. voice input. Not a port because a port allows one to insert a peripheral device but not really communicate. I have no idea what an expansion slot is. It could be d. voice input because this allows a person to hold an audible conversation.
But I'd go for modem because a modem lets you connect devices like laptops, tablets, phones, computers etc. and share data between them. So things like mailing are possible (I THINK)! <span />
Answer:
<h2>Option B: #VALUE</h2>
is the correct answer.
Explanation:
<h3>Reasons of #VALUE error:</h3>
- When cells are not given the expected type of value.
- If cells are left blank unnoticeable or for giving a null value.
- For entering dates and other numerical data in text form.
<h3>Correcting and fixing #VALUE error:</h3>
This type of error can only be fixed by finding the cell in which there is wrong data entered and correct it.
Fixing the #VALUE error is tricky as some functions automatically ignore the data that is invalid.
<h3>EXAMPLE:</h3>
- Suppose a cell contains the value as cost of the object and in order to make it 0, NA is inserted into the cell.
- While making total of all the costs, that particular cell might cause #VALUE error.
- Following image attach will help you clear the concept.
I hope it will help you!
