What is the measurement of the application's reliability as a non-functional requirement?
You cannot measure reliability as it is linked to a bunch of different factors. Uptime can be one of them, for web apps. For other software, it can be something like the prevention of data loss under any circumstances.
You'll have to define it more exactly by breaking it down into your detailed expectations, then you can quantify values to measure against.
It is a core problem with nonfunctional requirements that you cannot measure them easily. You'll have to work around that as described above.

I have realized that most of the problems that I solve on a day to day basis are done via two programming techniques: iteration or recursion.
Are there other techniques out there? Any book recommendations or online references?
the programming techniques that you use to solve the problems can be divided into types of algorithms (not into the loop or technique they use in there program, like you mentioned). some of the methods are..
1. Divide and conquer
2. greedy
3. dynamic programming

I'd love to know/see some example code from the lowest level. By this I mean the code that for example, sets the voltage to the speakers, or something equivalent. I can't imagine how this would look/work.
How could a piece of code possibly set/change a physical quantity? I'm not looking for some driver code, but the actual code that makes hardware 'work', or does it work in a different way?

I need to prepare a Software Requirements Specification Document for a small enhancement within an JAVA application.
I have tried goggling for the same but found the samples for whole application whereas I am preparing SRS for a small enhancement within an application.
Can anybody suggest the links or suggestions for preparing the SRS.
As you realized by yourself what you're asked isn't a Requirements Specification, which usually covers the whole set of requirements for a software.
What you've been asked is a Change Request, and it must be merged in the existing SRS. However something tells me that there's no SRS for the software you're dealing with, as your management doesn't know the difference between both...

I'm wondering about functional or non-functional requirements. I have found lot of different definitions for those terms and I can't assign some of my requirement to proper category.
I'm wondering about requirements that aren't connected with some action or have some additional conditions, for example:
On the list of selected devices, device can be repeated.
Database must contain at least 100 items
Currency of some value must be in USD dollar.
Device must have a name and power consumption value in Watts.
are those requirements functional or non-functional ?
Functional requirements are things the system does.
Non-functional requirements are quality attributes or aspects of how the system is designed, built or implemented.
Have a look at:
