There are also 16 bit Digital Signal Processors, which have become more popular than their 16 bit MPU conterparts because of the need to handle wider data in computation in signal processing applications.
Additionally the 16 bit Thumb Instruction set was introduced to optimize the code generations since 32 bit instructions are not consistently required.
The correct mix of 32 and 16 bit instruction set for code optimization and execution speed has been the key to success in the Thumb implementations.

  Quark :: View topic - Does Quark Support 16 Bit Images?
All layout application I'm aware of downsample images to a bit depth of 8 bit (as long as they are anyway able to import and handle 12 or 16 bit images correctly).
The only output format which would be able to keep a 16 bit image depth would be PDF 1.5 and newer which isn't supported by QuarkXPress 6.x (neither on the import nor output side).
So saving images in 16 bit makes sense if images must be changed later and to keep as much image and color quality as possible.

  Eight and Sixteen Bit Images
When a 16 bit version of AIR package is configured and compiled, a decision must be made about how data in 16 bit files generated by the AIR package will be represented.
The import mapping of 16 bit values to 8 bit values can be optimized by specifying the largest value represented in the 16 bit images, a step that is unnecessary if you are using a 16 bit version of AIR.
The header "bits/pixel" field is used to distinguish 8 bit data from 16 bit data, and the header "global maximum" and "global minimum" fields are used to distinguish the three different types of 16 bit data.

 8 and 16 Bit Microcontrollers
Rumors of the death of 8 and 16 bit processors are greatly exaggerated.
Though 8 and 16 bit processors were once the universal computing engine found in all smart products, today they are used in the realm of deeply embedded applications, ones that typically have a lot of I/O. Peripherals are important, as evidenced by the astonishing number of variants for some devices.
Infineon’s C163-L 16 bit microcontroller, as is typical of small form-factor devices, comes in a 100 pin TQFP (Thin Quad Flat Pack) configuration, measuring just 14 mm on a side, with 0.5 mm lead pitch (leads too small to see if you wear bifocals).

 Full 16 bit workflow - PanoTools
To use 16 bit workflow you need a camera capable of saving RAW files or a scanner plus application that allows to save 16 bit.
Shooting in RAW allows you to later generate 16 bit TIFFs from these files, with precisely adjusted exposure and white balance, or even different exposure and white-balance settings to assemble the images again in a more favoring way, eg another white-balance for the windows of interior-panos.
The only possibilities to achieve the task in 16 bit is either to use PTStitcher (with one of the GUI front-ends or with script) or the Photoshop compatible Panorama Tools Plugins in the 16 bit version provided by Thomas Niemann

 8 Bit and 16 Bit | Photoshop Articles
As each bit has two choices, 8 bits have 2x2x2x2x2x2x2x2 or 256 choices, which means 2 to the power of 8 or 256 colours.
A camera file or scan of an 8 bit depth will have a tonal range of 256, 0-255, which is 2 to the power of 8.
Bit depth will determine the number of steps between the maximum and minimum values, so a 16 bit image will produce much smoother tonal gradations.

16 bit digital audio was developed within the range of human hearing,(20-20,000hz)under the assumption that if you cant hear outside that range there was little reason to reproduce it.
As for the sample rate, that's a very hotly debated topic but for the 99.9% of consumer, their equipment is not going to have enough fidelity to allow them to discern the difference between 44.1 and 96, given that the person listening can actually tell the difference between the two (also less than 99.9%).

The byte may represent a character, such as the letter A or the numeral 3, or it may be eight bits of an instruction in machine language or of a numeric quantity represented in one of various binary formats.
In some systems, the eighth bit is used to expand the repertoire of characters beyond the 128 ASCII characters to provide for special graphics.
Also as in the case of the 8-bit machine, input from the keyboard and output to the screen or a printer is conducted in the form of ASCII characters carried within 8-bit bytes.

 CircleMUD List: 16 bit platform bug and binary compatibility is
After all, if CM was never 16 bit compatible it was most probably never used to any reasonable extent on a 16 bit platform, otherwise this bug would quickly have been discovered long ago.
Taking the prior assessment to a further level we can even go as far as to begin making more widespread use of the bitvector_t and possibly other types we were afraid of changing in stock CM in the past due to concerns over maintaining binary-compatibility.
In short, by realizing that CM never really worked on a 16 bit platform, it allows us the freedom to actually make it work on a 16 bit platform.

 Running a 16 Bit Application as a Seperate Process
As such, it stands to reason that 32 bit applications are simply going to run better than 16 bit applications.
This is because 16 bit applications require a separate set of DLL files, and basically rely on an entirely different set of instructions than those supported by Windows 2000.
Part of the reason that 16 bit applications run so much slower than their 32 bit counterparts is because of the overhead caused by having to rely on an NTVDM.

Dan Margulis, a noted high bit work-flow critic even changed his viewpoint after some colour scans that were converted to 8 bpc in the scanner were poor after edits, while a high bit converted to regular bit in Photoshop and then edited the same was superior.

 Applied Color Theory - Field Test of 8-bit vs. 16-bit
The hypothesis is: 1) bits of low significance do not make visible differences, 2) editing amplifies bits of low significance, causing their differences to become visible, therefore 2) when performing operations that "spread bits," fill them in with a pseudo-random pattern.
For the vast majority of the users on this list, 8 bit is going to be the way to go since pushing a lot of files through the workflow is bad enough when they are half the size of a 16 bit file.
More than 8 bits pre color is all you need and many capture devices deal with 10 bit, 12 bit, 14 bit, 16 bit etc. Photoshop takes all such 3high bit2 data and simply calls it 316 bit2 which is fine.

If an image is a bit underexposed and lacking in contrast, it may only use values between 0 and 199 perhaps (200 out of the possible 256 values).
Instead of counting the number of bits per channel, they are named after the total number of bits in all three channels together.
Thus, both are off by a factor or three (8 bits per channel times 3 channels = 24 bits total, and 16x3 = 48 bits).
