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 is syllabus for first year of computer science engineering?
Computer Science and Engineering is an engineering discipline, which focuses on the subject "Computers", from hardware to software, and is taught across most universities in Asia. Some of the most prominent ones are the Indian Institute of Technologies. Most universities offer B.Tech (Computer Science and Engineering) as bachelor degree and M.Tech(Computer Science and Engineering) as post graduate degree.
Candidates enrolled for the discipline are required to study basics of all core engineering along with papers from the main subject. Engineering Mathematics is also given prime importance.
What was the meaning of ispekulasyon?
ispekulasyon:ang kasaysayan ay naghahayag ng mga ispekulasyon o maaring maganap sa susunod na henerasyon.
Write the Arden's method to convert an NFA to DFA with expression?
here first we looking on the given diagram and after this we select all the incoming input like in q1 all the input are q1=q2 0+ q1 1 or q2=q3 1 + q2 0
q1 is a state and when q2 sent 0 then its going to q1 so the value add into the q1 ok same in q2...
What is an explanation of the term cybernetics?
Cybernetics comes from the Greek word Kybernetes, which means helmsman, and is the science involving communication and control between organic and mechanical systems.
A modern-day example of this science is cutting-edge prosthetics, which operate based on the neurological commands of the patient. Recently, advances have been made in games which can be played using your own neurological input, which is another form of cybernetics.
In popular fiction and movies, cybernetics usually involves enhanced devices and artificial limbs grafted to a person, or a person's brain transplanted into a machine. Examples of these are Robocop, Cyborg and the pen-and-paper roleplaying games Shadowrun and Cyberpunk. Cyberpunk is also the name of the writing genre involving cybernetic technology, started by the author William Gibson.
What is an infinite word automaton good for?
Infinite word automatons, invented by Buchi in the sixties, were used for reasoning about logic. Today they are used for formal verification of systems.
What is a sentence for overlapping?
It might be "I could not come to my friend's party because it was overlapping my dental appointment"
Computer science is the study of the principles and uses of computers.
Why do some students find computer science hard?
The hardest part about computer science is that a computer doesn't really allow anyone to "fudge" anything. A computer takes every command and executes it in a strictly literal sense as determined by its programming, so there is a high element of human error, both in terms of initial programming as well as when the software is being used.
A computer doesn't understand subjective or relative terms and since we as people tend to deal majoritively in that sense, trying to "think" like a computer is difficult at times.
Write a c program to find the sum of the digits of a number?
#include<iostream>
int sum_digits(int num, int base=10)
{
int sum=0;
while( num )
{
sum+=num%base;
num/=base;
}
return(sum);
}
int main()
{
int sum=sum_digits(42);
// assert( sum==6);
}
Is the Kullback Leibler divergence a metric?
Although it is often intuited as a distance metric, the KL divergence is not a true metric, as the Kullback-Leibler divergence is not symmetric, nor does it satisfy the triangle inequality.
Queues are commonly implemented for abstract routines and data access structures. In languages using object-orientation, they may be featured as classes. Some methods for implementation include circular buffers and linked tests.
A solid background in Math is important to those subjects because they all involve a lot of math. If you don't already know a lot of math (i.e algebra, geometry, trigonometry, calculus) then those subjects will be extremely difficult to get into and more importantly to do well in.
In physics you might have to calculate the force of an object in motion, the speed of light through a substance, or the frictional constant of a surface. All of those would require you to at least already understand varying levels of algebra. Engineering is based off of physics.
In computer programming, you will be doing a lot of explicit logical thinking and having a strong background in math will have developed such logical thinking skills. You will be asked to solve problems and to write a variety of programs and they will require you to understand math: whether your writing a program to calculate and display the slope of an equation or if your writing a program to calculate a business' taxes, you will first need to understand how to do that yourself before you can instruct the computer on how to do it.
Types of keys in database management system?
super key
foreign key
candidate key
surrogate key
unique key
alternate key
composite key
compound key
What are Semantic errors in a programming language?
Semantic or Syntax errors are errors in the way a programmer has written his code. The code does not conform to language standards and is incorrect.
Ex:
for(int i = 0, i++, i<10) {
}
The above is a syntactically incorrect declaration of a for loop in Java. The compiler would not let you compile this code successfully.
