Figure 1: An image — an array or a matrix of pixels arranged in columns and rows.
In a (8-bit) greyscale image each picture element has an assigned intensity that
ranges from 0 to 255. A grey scale image is what people normally call a black and
white image, but the name emphasizes that such an image will also include many
shades of grey.
Figure 2: Each pixel has a value from 0 (black) to 255 (white). The possible range of the pixel
values depend on the colour depth of the image, here 8 bit = 256 tones or greyscales.
A normal greyscale image has 8 bit colour depth = 256 greyscales. A “true colour”
image has 24 bit colour depth = 8 x 8 x 8 bits = 256 x 256 x 256 colours = ~16
million colours.

For bad software, probably a virus/malware/ransomware kind of thing. If it is good software, probably a program that organizes your files, adjusts certain things, but do not record your files (no programs are at the top of my head, sorry).
The most important security consideration for the station is code signing. With code signing, consumers may feel confident about the software they are downloading and can stop worrying about infecting their computer.
With code signing, consumers may feel confident about the software they are downloading and can stop worrying about infecting their computer or mobile device with malware. Code signing has grown in importance for software developers and distributors as more software may be downloaded from the Internet.
Malware can be easily installed on a victim's computer by an attacker who poses as a trustworthy source. As long as users only download software that is regarded as safe by their operating system, code signing ensures that these types of assaults cannot happen.
Nowadays, the Operating System looks for the digital certificate produced through code signing when software is downloaded onto a computer to ensure the security of the software being installed. The user is informed and given the option to stop or continue the installation if no digital certificate is detected.
