Computer Science
Computer Science is the systematic study of algorithmic processes that describe and transform information. It includes the theoretical foundations of information and computation and the practical techniques of applying those foundations to computer systems. Among the many subfields of Computer Science are computer graphics, computer programming, computational complexity theory, and human-computer interaction. Questions about Computer Science, terms such as algorithms and proofs, and methodologies are encouraged in this category.

What are The application of turing machine?
as turing machine acts as a recognizer, acceptor , generator
the applications are:
1)storage in finate control (eg:-string with alternate symbols)
2)multiple tracks (eg:-to check prime no. or not)
3)checking of symbols(eb:- palindromes checking)
What is passport automation system?
passport automation system is nothing but the applicant downloading the application from the net source and sending the required application to the particular organisation
Why do models of complex economic and social system often give poor or inconsistent result?
The data describing current conditions or characteristics might not be complete or accurate

Why are output files for the printer normally spooled on disk before being printed?
If the printer were assigned as soon as the output appeared, a process could tie up the printer by printing a few characters and then going to sleep for a week.
What are the limitations of Hamming Code?
Hamming code handles only single-bit errors-two or more errors will cause an incorrect syndrome value. It can detect double bit error but not corrected
It is exactly as important as it is to understand and describe the basic internal and external components of your car's various mechanical and electrical systems.
For the average user of both computers and cars there is no importance at all to being able to do this, all that is important is to know how to use them to do the user's tasks satisfactorily. The only persons that these are important to are the people responsible for repairing and maintaining the devices.
What is operation signature in UML?
Syntax for UML operation is:
operation ::= [ visibility ] signature [ oper-properties ]
Signature of the operation has optional parameter list and return specification.
signature ::= name '(' [ parameter-list ] ')' [ return-spec ]
Name is the name of the operation. Parameter-list is a list of parameters of the operation in the following format:
parameter-list ::= parameter [ ',' parameter ]*
parameter ::= [ direction ] parm-name ':' type-expression [ '[' multiplicity ']' ] [ '=' default ] [ parm-properties ]
See details and examples in the provided link.
Difference between boundary fill algorithm and scanline polygon fill algorithm?
in scan line polygon fill, each can line crossing a polygon, the area fill algorithm locates the intersection point of the scan line with the polygon edges. These intersection points are then stored from left to right and the corresponding frame buffer positions between each intersection painr are set to the specified fill color.
In boundary fill, approach to area filling is to start at a point inside a region and paint the interior outward toward and the boundary.
Where is data stored when it is in virtual memory?
Virtual memory, when not active, is written to a swapping area. The swapping area is often on a designated area of the system HDD (hard drive), or a separate HDD. If faster storage is available, it may also be on a designated semiconductor storage facility such as an SSD, SD or USB flash drive.
What are the four common mode of operation?
There are 4 operation basiclly done in micro processor
1.memory read
2.memory write
3.i/o read
4.i/o write
What are the macro functions of communication?
Macro functions of communication means the basic and the important functions of communication.
These functions are much more significant than the micro functions of communication.
These functions include:
1.The emotive functions which deal with communicating inner states and emotions.
2.The Directive functions to affect the behavior of others etc.
pass 1 assembler is assembler which convert assembly level language into machine level language in one pass only
What is the difference between P and NP complexity classes?
P is the class of problems for which there is a deterministic polynomial time algorithm which computes a solution to the problem. NP is the class of problems where there is a nondeterministic algorithm which computes a solution to the problem, but no known deterministic polynomial time solution
Which are the factors that decide number of passes for a compiler?
There are many. I have encountered compilers with as few as 2 passes to as many as 63 passes (this number of passes were necessitated by the very tiny magnetic core memory of the machine). I even encountered a compiler that the programmer that wrote it claimed was a 1 pass compiler, but on detailed examination all he had done was "piped" the output of pass 1 to the input of pass 2 (instead of writing it to an intermediate file between passes), so it was actually a 2 pass compiler.
I have also encountered a language (the US Navy's CMS-2) that has both syntactic and semantic ambiguities that made it impossible to write a compiler (no matter how many passes) that could reliably compile all code given to it, to do what the programmer intended.
How cooperating processes are communicating?
you can make effective communication between 2 processors by using volatile keyword..
NFA - Non-deterministic Finite Automaton, aka NFSM (Non-deterministic Finite State Machine)
An example: Feet for first piece of fabric: 2 Inches for first piece of fabric: 7
Feet for 2nd piece of fabric: 2, Inches for 2nd piece of fabric: 6
I need the program to print: Feet: 5 Inches: 1
