How does software measurement affect software quality and productivity?
It depends on whether you are measuring things that are related to quality or not.
Figuring out what to measure can be very hard, but when you measure the correct things:
- Measuring defect removal efficiency; productivity +20%, quality +30%
- Measurement of bad fix injections; productivity +19%, quality +28%
- Formal measurement programs; productivity +20%, quality +30%
- Measurement of requirements changes; productivity +16%, quality +22%
- Etc
Not measuring quality can lead to productivity falling 14% and quality by 19%.
If you measure the wrong things quality will NOT improve, i.e. there are organizations that focus on measuring:
- lines of code
- hours the developers put in
These are things that are easy to measure but have nothing to do with quality, it does not prevent many organizations from confusing measurement with quality improvement.

STORE-means to keep the result or instruction or prog to a permanent location for further use
load means take a prog to memory.
store means save the prog to the parmanent memory
What happens if a software program is not tested before deployment?
If it hasn't been tested at all, chances are it won't work at all and any possible customers will switch to a competitor's product.
If you have been reliant on unit testing for making sure your product works, it will probably work for some customers, but eventually hidden bugs and errors will emerge.
Is a 2-to-1 mux functionally complete?
Yes.
AND operation
= f(A,B) = AB = A'f(0,B) + Af(1,B)
= A'(0B) + A(1B) = A'0 + AB
OR operation
- f(A,B) = A+B = A'f(0,B) + Af(1,B)
= A'(0+B) + A(1+B) = A'B + A1
NOT operation
- f(A) = A' = A'f(0) + Af(1)
= A'(1) + A(0)
Fault tolerance is the ability of a system to continue working even when a fault exists. In the case of RAID, which stands for Redundant Array of Inexpensive Discs, fault tolerance is provided by having data recorded on more than one drive, and also by having more than one power supply. Note that RAID 0 is not fault telerant because it is simply stripes the data to increase size and bandwidth, but provides no redundancy. RAID 1 and RAID 5 are fault tolerant, to various levels.
What will you do if all IT industries get flushed out and you have no chance to do anything?
If that should ever happen, and it is very doubtful, then that would mean technology as collapsed. Considering that the Internet, networking, and computer software run the economies of the world it is very unlikely.
In other words, if that should happen then the entire world would be in trouble (and unemployed).
Of course, in any industry, if you find yourself out of work then it might be necessary to think about job retraining, depending on where the job demand might be.
PV Elite is a software package from COADE, Inc. for the design and analysis of pressure vessels and heat exchangers. The package bi-directionally links to COADE CADWorx Plant Design Suite and COADE PV Fabricator for automation of the production of pressure vessel drawings.
What is Unit regression testing?
It is running the same tests that found the error again after an error has been fixed to ensure it has been fixed and no other errors have been introduced as a result of what was done.
What is address binding in operating systems?
A program, to be executed, must be brought to main memory. The instructions that use addresses in a program, must be bound to proper address space in main memory. Address binding is a scheme that performs this job. It can be thought as a mapping from one address space to another. There are bindings available as follows: Compile time binding Load time binding Execution time binding
What is the difference between Xvid and Divx?
They are two different implimentations of MPEG-4 video/audio.
When DivXNetworks didn't follow through with their promises of an open version, Xvid was created. Xvid is compatible with DivX. DivX is available on only certain systems. Xvid (deliberate reverse of DivX) is a open version available for every major system.
Both use patented technology, so you should check your country's laws before considering them.
