What are the differences between the checksum and check digit?

A checksum in public can be any size, although generally, they exist some suitable number of bits for computation, such as 32. The more extensive the checksum, the wider the range of errors it can capture. For instance, the checksum utilized for credit card numbers will notice changed digits that exist after each other, but not reversed digits that exist split by a single digit.

All cryptographic hashes (like MD5, SHA, etc.) can be utilized as checksums, but not all checksums exist cryptographic. CRC-type checksums aren’t cryptographic, but they’re extremely quick to calculate, and so they exist generally utilized for things like hard drive checksums where you don’t require the cryptographic functionality, but you accomplish want to notice an extensive range of probable errors.

A one-point perspective drawing means that the drawing has a single vanishing point, usually (though not necessarily) directly opposite the viewer's eye and usually (though not necessarily) on the horizon line. All lines parallel with the viewer's line of sight recede to the horizon towards this vanishing point.

One Point Perspective is a type of linear perspective that uses a single vanishing point to create the illusion of depth in a work of art.

Digital cameras often have trouble with auto white balance, which can result in unattractive blue, orange, or green casts.

A: true

B: false

Answers

The statement about digital cameras often having trouble with auto white balance which can result in unattractive blue, orange or green casts is; A: True.

Let us first define white balance(WB).

White balance is defined as the process of removing unrealistic color casts, in a way that will make the objects that appear to be white in person to also be appear white in the photo.

Now, for a camera to have the right white balance, it will have to consider the "color temperature" of a light source i.e the relative warmth of white light.

Finally humans eyes are very good at judging which is white under different light intensities or sources, but that is not the case with digital cameras because they struggle with auto white balance and that could lead to different colors like unattractive blue, orange, or even green color casts.

When the condition of recursion is met, the base case is returned, else, the recursive case is continued.

In the function given above,

the base case is 'return x' under the condition 'if x == 1'. The recursive case is 'return x * factorial(x - 1)'.

So, the function runs until the base case it met and then it stops.
