Sphinxa [80]

Answer: Machine learning

Explanation:

The technology that could be combined with the current solution to do this is the machine learning.

Machine learning refers to the use and development of the computer systems which can learn and adapt without them following explicit instructions. This is done through the use of statistical models and algorithms in order to analyse inferences from the patterns in data.

Since the bank wants to streamline their operations for the receiving and processing checks while also enhancing the solution to recognize signs of potential check fraud, then the machine learning can be used.

Expalin the defference between the driver of a desktop and a laptop

Pani-rosa [81]

Answer:

None, drivers are hardware specific, if both devices share the same hadware manufacurer they tend to have the same drivers.

A driver is a software component that lets the operating system and a device communicate with each other. So asking for a difference in drivers is as asking the difference in hardware in both devices, though one tends to be more intergrated they are all the same in low level functions

Also drivers might not even communicate directly with the device but send a request. thats why some drivers can be written directly into an operating system.

When is the following expression true? (2 points)

ipn [44]

Answer:

1) If and only if a and b have different values

Explanation:

Given

Expression: !(!a || b) || (!a && b)

Required

When is it true?

The expression is true when the values a and b are different and the proof is as follows.

(1) Assume that: a = true and b = false

!(!a || b) || (!a && b)

= !(!true || false) || (!true && false)

!true = false, so the expression becomes:

= !(false|| false) || (false && false)

In boolean, false|| false = false and false && false = false. So, we have:

= !(false) || (false)

!(false) = true, so, the expression becomes:

= true || (false)

Lastly, true || false = true

(2) Assume that: a = false and b = true

!(!a || b) || (!a && b)

= !(!false|| true) || (!false && true)

!false = true, so the expression becomes:

= !(true|| true) || (true && true)

In boolean, true|| true = true and true && true = true. So, we have:

= !(true) || (true)

!(true) = false, so, the expression becomes:

= false|| true

Lastly, false || true = true

<em>This expression is false if a and b have the same value</em>
