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.

When and why is it required to inherit virtual base class?
Whenever two or more classes are derived from the same base class, and another class is derived from both derivatives via multiple inheritance, and the common base class can be shared amongst all derivatives.
For instance, if a base class, V, is a common base class of two derived classes, A and B, and class D is derived from both A and B, then class D will inherit two separate instances of class V (one from A, the other from B). By declaring V to be virtual in both A and B, class D will only inherit one instance of V, which is then shared between A and B. Any changes made to the member variables of the shared V will be automatically reflected in A, B and D.
Bear in mind that not all base classes can be declared virtual. If V contains any member variable that must be unique to A and B, then A and B cannot share the same instance of V.
It would therefore follow that D probably cannot share V with either A or B. If D requires its own instance of V, the only solution is for D to inherit from A, B and V, thus A, B and D will each have their own separate instances of V.
However, if D can share an instance of V from either A or B, then there is no need for D to inherit its own copy of V. In this case, you can use the scope resolution operator to refer to a specific instance of V, whether it belongs to A or B. In other words, A::V or B::V.
Ultimately, the decision to make V virtual in direct derivatives will depend on whether a single instance of V can be shared between those derivatives and that is entirely dependant upon the actual purpose of V. To be a virtual base class, V should ideally be an abstract data type with no unique member variables whatsoever. And provided classes A, B and D override all the pure-virtual methods inherited from V, there will be no ambiguity whatsoever. Invoking a pure-virtual method on V will call the most-derived method in D, which can, optionally, call the overridden methods in either A or B, or both, via their scope resolution operators.
What is difference between single and double selection structures?
In programming
- Single-selection structure - (if statement) Performs an action, if a condition is true; skips it, if false. Selects or ignores a single action (or group of actions).
- Double-selection structure - (if…else statement) Performs an action if a condition is true and performs a different action if the condition is false. Selects between two different actions (or groups of actions).

Can assemblers be used in any operating system?
An assembler must be specifically written to accommodate both the operating system, as well as the underlying CPU architecture.
A bit size is one. It can be either a 0 or 1. Eight bits together is called a byte.
Four bits (half of a byte) is called a nibble.
What are facts about John Tukey?
While the computer/information term 'bit' was first used in a research paper by Claude Shannon in 1948, the term was coined by John Tukey as a contraction of binary digit while he was working on concepts of computer design. I suppose during the holidays we could say it is a bit of Tukey.

A C program using dynamic memory allocation to sort n names in ascending order?
Writing a C program that uses dynamic memory allocation to sort names in ascending order is a typical computer science assignment. To write this program, you must be in UNIX.
Is NotePad Plus Plus a compiler?
Notepad++ is a text editor, not a compiler. You can however, enter source code into Notepad++ and then compile it with a compiler such as GCC.
What is the scope of studying computer science?
it's you who find scope.means lots of oppurtunity are there in the field of computer science.you should search the net a little more than just to ask a question.
What term number of bit central processing unit can process at one time?
Word length is the number of bits that can be processed at one time.
What is diff between computer engineering and computers science engineering?
In computer science and software engineering;Here is a quick overview of the three computing majors that our department offers. I teach primarily software engineering courses so it may be a bit biased.
1. Computer Science covers the core concepts and technologies involved with how to make a computer do something. Learning to program a computer by writing software is essential, and computer programming is used in most computer science courses. You will learn details about how computers and networks work, but with an emphasis on how software and programming languages work. You will learn how to make them do very sophisticated things (e.g. graphics, robotics, databases, operating systems). You will also learn about the theory behind how and why computers and software work. In your senior project, you will tackle a problem at the frontier of computer science. You may be building a new system, discovering better ways to design software, or developing new algorithms for projects in entirely different fields; it's up to you. Past student projects include: Video Games, computer modeling and animation tools, and a Linux driver for the Wii remote.
2. Computer Engineering teaches you how to design systems that include both computer hardware and software. You will take classes on how computer hardware works and how to build a computer. You'll take software classes with an emphasis on hardware-related software such as device drivers and operating systems. Computer engineering courses are taught by faculty from both the computer science and the electrical engineering departments. Working computer engineers design computers and the basic software that runs them, including both personal computers and the "embedded" computer systems that run cars, aircraft, videogames, etc.
3. Software Engineering focuses on how to design and build software in teams. You will take many of the same courses as you would in computer science, but you will take additional courses that teach you about topics like requirements engineering, software architecture, software testing, and software deployment. You will learn about working with people (communication, management, working with non-technical customers), processes for developing software, and how to measure and analyze the software product and the software process. The software engineering major requires that you take a three course (nine-month long) sequence called the software engineering capstone. The capstone courses are centered around a large project for an outside customer. In recent years we have built web applications for Intuit (makers of Quicken, QuickBooks, and TurboTax) and Amgen (a bio-engineering/pharmaceutical company). Students work in teams of four or five people to elicit and develop requirements for the system, design an architecture, build prototypes, implement the system, then deploy and maintain the system.
Answer-
Computer Science- Computer science is becoming a rapidly growing discipline as the technological age advances. Computer scientists believe that computers are a fundamental part of the world and that an age will come when everybody has several computers. It is a more complex field than simply building computers or writing programs. Computer scientists study problems to determine if they can be computed, compare algorithms to decide on the best solution, create programming languages to express these algorithms, design and build computer systems to execute specifications from research, and apply algorithms to application domains, or sets of software systems that share design features.
Software Engineering- Software engineering is the computer science discipline concerned with developing large applications. Software engineering covers not only the technical aspects of building software systems, but also management issues, such as directing programming teams, scheduling, and budgeting.
What is the use of theory of computation?
In simple words to learn any natural language like ENGLISH, HINDI,FRENCH....
firstly we need to learn the vocabulary and grammar of that language.
That means we have to learn how the language is actually specified.
In the same way programming languages(formal languages) like C,C++, JAVA....
has their own vocabulary and grammar and such grammar is specified with the
help of mathematical model that is called as Theory of Computation.
simple hill climbing uses evaluation function i.e evaluation of goal state & finding of better state, these 2 things can be done through heuristic knowledge, where as steepest ascent hill climbing have three major problem states i.e. local maximum, palteau & ridge which can be overcome by backtrack, jump, move several direction @ same time respectively & according to me steepest ascent hill climbing is extend version of simple hill climbing. if my whole concept is wrong let me know.

Who was the woman computer scientist who developed the first computer?
That would be Ada Lovelace. Here's one article about her: http://www.cs.yale.edu/homes/tap/ada-lovelace.html but if you Google "Ada Lovelace" you will get many more.
Ada Lovelace was the first programmer.
What does programmatic mean in computer programming?
It means the same thing it does everywhere else: in a step-by-step manner.
A network topology is a description of the way computers are connected to each other and to other devices on a network. It can refer to the physical connections (the way the wires interconnect or the routing of wireless signals) or it can refer to the logical connections (the way computers can see each other or not see each other even though they have a physical connection.
The topology can refer to a home network with a handful of computers and printers or it can extend to vast sections of the Internet.
Some examples of topologies are ring, bus, tree, mesh and each describes the way the links are made. Network topology is a huge topic and the subject of more books than can be counted. A link is below that offers some simple examples of topolgy and might be a springboard for more study.
Is the high-level language is also an object oriented program?
Not necessarily.
Any language with an object-oriented approach will be a high-level language, but a high-level language does not have to use an object-oriented approach.
