Software Engineering
Software engineering is the process of applying well-developed techniques and practices in order to create new software products. Questions about everything from design patterns to requirements and specification belong here.

Why does a fridge door open from left to right or counter clockwise direction?
It's arbitrary. Many refrigerators (like mine) can be set up to open either way.
A Milestone Chart is a Project Control Chart that graphically depicts key events along a timescale, usually with triangles representing each event. It can depict a single event or a culmination of events. It can mark specific points in the project where checks can be made to see if the project is on time and where it should be. The best place to locate milestones is at the completion of a major activity.

Variables are items, which change their values during the execution of a program.
Constants do not change the value during the execution of a program.
What is an example of an aggregate object?
An aggregate object is an object that contains other objects for the
purpose of grouping those objects as a unit. It is also called a
container or a collection. Examples are a linked list and a hash table.
What are the boolean theorems?
Commutative x + y = y + x x . y = y . x Associative x+(y+z) = (x+y)+z = x+y+z x.(y.z) = (x.y).z = x.y.z Distributive x.(y+z) = x.y + x.z (w+x)(y+z) = wy + xy + wz + xz x + xy = x x + x'y = x + y where, x & y & z are inputs.
What is the wave form of clipping circuit?
As a sinusoidal signal is clipped the waveform approaches a square wave.
Top 10 college of engineering in Orissa?
well as per my opinion i think according to the placement the ranking list is # NIT # KIIT # CET # NMIET # UCE # SILICON # OEC # NIST # ITER # CV RAMAN # GITA NMIET is placed No:1 in giving 100% placement to all its students.
What is the best command to use to view the routers interface status and protocol status?

What are the two ways in which control structures can be combined?
Control Structures change the flow of a program.
Control Structures can be combined using what is known as Nesting.
In Nesting a control structure is put within another Control Structure
Example
If (x==y ) If (y==z) then do something
While(X is Not 0) While ( Y is Not 100 ) then do something.
Deference between prototype and incremental model?
In incremental model the real product is designed, implemented, integrated and tested as a series of incremental builds. while
In prototype model the prototype (not the real product) is designed, implemented, integrated and tested as a series of incremental builds
Iam not finding any difference between sdlc and rad please explain?
The reason why you might not find differences in the sdlc and rad is because RAD is a more sped-up version of the SDLC. RAD is typically used in small to medium size projects, while the SDLC is generally used for large projects. Another difference is that in the SDLC, one can control the scope creep of the project, whereas that is very limited when one implements RAD because you give it up for faster implementation times. In RAD you have alot of feedback from the user to refine the program more to the aspects of the user, whereas you dont get the same user input in the SDLC. This feedback loop is another reason that RAD is sometimes chosen over the SDLC
What is a default access specifier for variable in c sharp?
Default access specifier in c# is private.
if you don't specify it automaticaly takes it as private.
Which job pays better - a computer programmer or an HVAC technician?
The answer to this question may vary depending on the employer and responsabilities assigned to the specific position. As an example, a low level programmer for a mom-and-pop software company is not going to make as much money as the lead programmer for Microsoft. Nor would an HVAC technician employed by an appointment based home repair contracting company be paid as much as one responsible for, say, overseeing an entire university or large company campus. The lowest paid programmer may make less than the highest paid HVAC technician. But generally speaking, computer programmers tend to have higher salaries and better benafits and opportunities for advancement than HVAC technicians, depending on who they work for.
Difference between grant and revoke statements in sql?
grant will give permission to the user on database by using revoke we can remove the permission
Hex is used by computers to store information because it is the most compact method to do so. Four lines of information can store 16 different conditions:
0000 is 0
0001 is 1
0010 is 2
0011 is 3
0100 is 4
0101 is 5
0110 is 6
0111 is 7
1000 is 8
1001 is 9
1010 is A (10)
1011 is B (11)
1100 is C (12)
1101 is D (13)
1110 is E (14)
1111 is F (15)
Pretty cool huh!? Your five fingers could store 32 separate counts.
A Physical Data Flow Diagram is a diagram showing howparticular functions are performed within the data flow as opposed to a Logical DFD which only shows what functions are performed.

How can you get the information about luminance using CCD Camera?
hi all. i really need your help. i have colorimeter which can get the information about RGB, luminance of light source such as LED. but i don't know where the colorimeter get the information from and how? recently i found so many articles about CCD. and i understood, the CCD Camera can get the value of luminance of light source. CCD is just a image sensor. when i take a video of LED , each cell of CCD has information about electric charge and CCD analyse brighteness based on electric charge. and it can be display as a signal. that's just a theory. i need, how can i get the information about luminance!?? i'll take a video of LED using CCD Camera or special colorimeter, and connect it to computer so that i can get the information. does anyone can let me know? please help me thanks
