Answer:

Symmetric, asymmetric and one-way hash cryptography.

Explanation:

Cryptography is a way of protecting data information and communication, using encryption keys and is only decrypted when it gets to the intended receiver.

There are three ways of which cryptography can be used to protect data. They are;

1. Symmetric cryptography

2. Asymmetric cryptography

3. One-way hash cryptography

Symmetric cryptography requires for one key to be used to encrypt and decrypt information. Asymmetric cryptography requires two keys, private and public keys that are mathematically related to encrypt and decrypt information. Both must be used together to encrypt and decrypt data.

One way hash uses an algorithm to convert a random length data to a fixed length encrypted data.

<h3>What is printing?</h3>

Printing can be defined as a process that typically involves sending print jobs from a computer system to a printer, especially through the print queue.

In Computer technology, "cancel Printer1-17 Printer1-21" is a command that should be used to remove the two (2) print jobs from the print queue of Printer1 which is yet to start printing.

One friend claims that a dual-core system runs at twice the speed as a single-core system; another friend disagrees by saying th

lidiya [134]

Answer:

the first friend

Explanation:

It is important to remember that a core is the brain of the CPU (central processing unit), which means one who has a dual-core is having "a dual brain" to process information faster.

Consider also, IT experts often acknowledge that in terms of speed of execution, it is proven that, "dual-core systems" are faster (even twice faster) than a "single-core system". The other friends were wrong because they disagreed with a widely accepted fact that dual-core is faster than single-core; and of course, we know that without them being faster they can't run twice the applications and twice the data.

Therefore, we can make the conclusion that the first friend's response is correct.

Write a program for determining if a year is a leap year. In the Gregorian calendar system you can check if it is a leaper if it

SOVA2 [1]

Answer:

def leap_year_check(year):

return if int(year) % 4 == 0 and (int(year) % 100 != 0 or int(year) % 400 == 0)

Explanation:

The function is named leap_year_check and takes in an argument which is the year which we wish to determine if it's a new year or not.

int ensures the argument is read as an integer and not a float.

The % obtains the value of the remainder after a division exercise. A remainder of 0 means number is divisible by the quotient and a remainder other wise means it is not divisible by the quotient.

If the conditions is met, that is, (the first condition is true and either the second or Third condition is true)

the function leap_year_check returns a boolean ; true and false if otherwise.
