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.

How to write logic for equivalent?
Difference between crisp logic and fuzzy logic?
Crisp :
- Binary logic
- It may be occur or non occur
- indicator function
Fuzzy logic
- Continuous valued logic
- membership function
- Consider about degree of membership
How can you promote patriotism?
By teaching children the history of their country in an engaging and neutral way.
What is the difference between polynomial and non polynomial time complexity?
Polynomial vs non polynomial time complexity
Propagation of operation in object modeling?
Propagation means triggering ie something which fires automatically. Thepropogation of operation is applied with aggregation, if some operation is applied with the high level aggrigate the same operation will be performed with all lower aggregates. For example in aggregation between document and paragraph if we will perform an operation copy with document it will automatically applied with paragraph also. This propagation of operation.

Why is a high level language less error prone?
High level languages are far more descriptive and, generally, more like a natural language. In my experience, it has been a lot easier to make a typo in a low level language because you are doing things like directly accessing memory locations and using registers for storage.
Cognition is the development of information to knowledge. The act of cognition consists of representing and transforming information. This can be done by sensing something directly, or indirectly by reasoning.
Artificial cognition is the process of representing and transforming information artificially.
It is done by representing multidimensional intersections of sets in bitwise manner so they can be operated on by logical instructions in a computer.
Using this technology, a computer, having a database with definitions of motorboat, taxi, rowboat, and rickshaw, can conclude that a taxi is to a motorboat as a rickshaw is to a rowboat, in as few as four clock cycles, provided the computers registers are big enough to hold the definitions and the definitions are already loaded.
No.
If you have one IP per customer, you don't need to create smaller subnets.
(You won't have enough addresses though - the first and last addresses of the block will be the network and broadcast addresses and won't be useable. You'll only have 1022 usable addresses)
What is full form of DFA and NFA?
DFA - deterministic finite automata
NFA - non-deterministic finite automata
How are floating point numbers handled as binary numbers?
Floating point numbers are typically stored as numbers in scientific notation, but in base 2. A certain number of bits represent the mantissa, other bits represent the exponent. - This is a highly simplified explanation; there are several complications in the IEEE floating point format (or other similar formats).

Advantages and disadvantages of bubble sort?
This algorithm has several advantages. It is simple to write, easy to understand and it only takes a few lines of code. The data is sorted in place so there is little memory overhead and, once sorted, the data is in memory, ready for processing. The major disadvantage is the amount of time it takes to sort. The average time increases almost exponentially as the number of table elements increase. Ten times the number of items takes almost one hundred times as long to sort.
How many bit strings are there of length eight?
Every bit can either be a 0 or 1. So to find the amount of bit strings of length either, you do 2length to find the amount of bit strings there are of a given length.
What you hope to gain from studing access to high edgucation in computing?
More knowledge. If you know more you can do more. For example i like web designing. Its the easiest way of expressing your colorful ideas to millions of people with very small lines of codes which are basically like symbols.
Like "Yo dude wassup...... Nothin much" can convey a lot of information among the 2 persons the web development languages can convey a huge set of instruction to the browsers with little words.
Furthermore is it not interesting to learn about the substance you use everyday. The way it works. To master its function and discover newer ones yourself. Then going on to develop our very own magical machine that not only saves time but enhances our lifestyle.
Can you load the server object dynamically and If so what are the 3 major steps involved in it?
can aserver objectbe loaded dynamically
What are commonly used terms in computer appreciation?
Sleek, speedy, fast, fine UI, highly productive, etc.
What is meant by binary valued quantities?
Binary-valued quantities can be 0 or 1, true or false, right or wrong. There are only 2 possible values.
A relation may be in 2NF if
1. it is in 1NF &
2. Every non prime attribute functional dependent on primary attribute
What is the first np-hard problem?
You can use the bounded tiling problem. Given a problem in NP A, it has a turing machine M that recognizes its language. We construct tiles for the bounded tiling problem that will simulate a run of M.
Given input x, we ask if there is a tiling of the plane and answer that will simulate a run of M on x. We answer true iff there is such a tiling.
What is the difference between Computer Science and IT engineering?
Computer Science deals with engineering aspects of computer hardware and software. To be more clear it will deal about microprocessors, compilers, datastructures, algorithms and fundamental blocks of computer science. Computer scientists deal with inventing faster processors or highly optimized algorithms IT or Information Technology is the application of hardware and software for a business purpose. IT professionals deals with all kinds of business like entertainment, banking, retail or any such and try to provide solutions to business problems using software installed on appropriate hardware. As many a times software solutions may not be available off the shelf so they may write custom programs to meet the business needs
Explain how ict contribute to the society?
1. Introduction
* Information and communication technologies or ICT is about digital information passing between devices. ICT development has changed every aspect to the human society. It has affected our life in many ways.
2. The Impact of ICT on Society
* A.) Faster communication speed
* - In the past, it took a long time for any news or messages to be send. Now with the internet, news or messages are sent via
* e-mail to friends,business partner or anyone efficiently.
* - with the capability of bandwith, broadband and connection speed on the internet, any information can travel fast at an instant. It saves time and is inexpansive
* B.) Lower Communication Speed
* - Using the internet is cost-effective than the other mode of communication than the other mode of communication such as telephone, mailing or Korea Service. It allows people to have access to large amounts of data at a very low cost.
* - With the internet we do not have to pay for any basic services provided by the internet. Furthermore, the cost of connection to the internet is relatively cheap.
* C.) Paperless environment
* - ICT technology has created the term paperless environment. This term means information can be stored and retrieved through the digital medium instead of paper. Online communication via email, online chat and instant messages also helps in creating the paperless environment.
* D.) Effective Sharing of Information
* - People can share and exchange opinions, news and information through discussion groups, mailing list and forums on the internet. This enable knowledge sharing which will contribute to the development of a knowledge based society
* E.) Social problems
* There are some of negative effects of ICT.
* Nowadays, people tend to choose online communication rather than having real time conversations.
* People tend to become more individualistic and introvert theft, hacking, pornography and online gambling. This will result in moral decadent and generate threat to the society
* F.) Health Problems
* A computer may harm the user if they use it if they use it for a long hours frequently.
* Computers users are also exposed to bad posture, eyestrain, physical and mental stress.
* In order to solve the health problems, an ergonomic chair can reduced back strain and a screen filter is to minimize eyestrain.
6. Conclusion
* ICT is redefining the economic, social and cultural scene
* The impact of ICT is much more and further reaching than any other technology invented so far
* ICT is empowering society in both the economic and social contexts
* Digital Divide is increasing among and within nations
* The Government should recognise that communication and knowledge are two intertwined success factors .
