       Computer-Science-General-Aptitude       Computer-Science-Basics
Question 1 Explanation: 
Since 1966, the Turing Award has been given annually by the Association for Computing Machinery for technical or theoretical contributions to the computing community. It is widely considered to be the computing world's highest honour, equivalent to the Nobel Prize.
Question 2
International domains names in applications(IDNA) uses which encoding syntax to represent Unicode characters in ASCII format
A
Puny code
B
HASH code
C
DHTMLed
D
BER code
       Computer-Science-General-Aptitude       Computer-Science-Basics
Question 2 Explanation: 
Initially, domain names were restricted to ASCII characters. This was a significant burden on people using other characters. Suppose, for example, that the domain name system had been invented by Greeks, and one could only use Greek characters in URLs.Most of the world’s population faced this situation until recently, because their languages use non-ASCII characters. A system was introduced in 2003 for internationalized domain names (IDN).This system is called Internationalizing Domain Names for Applications, or IDNA2003 for short. This mechanism supports IDNs by means of a client software transformation into a format known as ​ Punycode​ . A revision of IDNA was approved in 2010 (IDNA2008). This revision has a number of incompatibilities with IDNA2003.
Question 3
IPv6 is developed by
A
IETF
B
ANSI
C
ISO
D
IEEE
       Computer-Networks       IPv4-an-Fragmentation
Question 3 Explanation: 
Internet Protocol version 6 (IPv6) is the most recent version of the Internet Protocol (IP), the communications protocol that provides an identification and location system for computers on networks and routes traffic across the Internet. IPv6 was developed by the ​ Internet Engineering Task Force (IETF)​ to deal with the long-anticipated problem of IPv4 address exhaustion. IPv6 is intended to replace IPv4.

C
Von neumann
D
Sabeer Bhatia
       Computer-Science-General-Aptitude       Computer-Science-Basics

Isaac Asimov's "Three Laws of Robotics"
1. A robot may not injure a human being or, through inaction, allow a human being to come to harm.
2. A robot must obey orders given it by human beings except where such orders would conflict with the First Law.
3. A robot must protect its own existence as long as such protection does not conflict with the First or Second Law.
Question 8
Quantum computers are assessed to be___
A
Supra-Turing Machine
B
Sub-Turing Machine
C
Equivalent to Turing Machine
D
Equivalent to PDA
       Computer-Science-General-Aptitude       Computer-Science-Basics
Question 8 Explanation: 
Although quantum computers may be faster than classical computers for some problem types, those described above cannot solve any problem that classical computers cannot already solve. A Turing machine can simulate these quantum computers, so such a quantum computer could never solve an undecidable problem like the halting problem.
The existence of "standard" quantum computers does not disprove the Church–Turing thesis. It has been speculated that theories of quantum gravity, such as M-theory or loop quantum gravity, may allow even faster computers to be built. Currently, defining computation in such theories is an open problem due to the problem of time, i.e., there currently exists no obvious way to describe what it means for an observer to submit input to a computer and later receive output.
Question 9
Constantinos Daskalakis proved that computing the Nash equilibrium for a three-person game is computationally___
A
Tractable
B
Intractable
C
In P
D
Decidable
       Computer-Science-General-Aptitude       Computer-Science-Basics
Question 9 Explanation: 
The definition of Nash equilibrium is then made up of two components:
1. Players are rational: Each player’s strategy maximizes his payoff, given his beliefs about the strategies used by the other players.
2. Beliefs are accurate: Each player’s beliefs about the strategies used by the other players are true.
Condition (1) is innocent enough; it’s condition (2) that is tougher to swallow.
The problems that cannot be solved in polynomial time are termed as intractable problems.

       Computer-Science-General-Aptitude       Computer-Science-Basics
Question 10 Explanation: 
The term was coined by Tim Berners-Lee for a web of data (or data web) that can be processed by machines that is, one in which much of the meaning is machine-readable. While its critics have questioned its feasibility, proponents argue that applications in industry, biology and human sciences research have already proven the validity of the original concept.
Question 11

A
10
B
100
C
1000
D
100000
       Computer-Science-General-Aptitude       Computer-Science-Basics
Question 11 Explanation: 
MIT researchers have shown that by exploiting the polarization of light, the physical phenomenon behind polarized sunglasses and most 3D movie systems, they can increase the depth resolution of conventional 3-D imaging devices as much as 1,000 times.
“Today, they can miniaturize 3D cameras to fit on cell phones,” says Achuta Kadambi, a PhD student in the MIT Media Lab and one of the system’s developers. “But they make compromises to the 3D sensing, leading to very coarse recovery of geometry. That’s a natural application for polarization, because you can still use a low-quality sensor, and adding a polarizing filter gives you something that’s better than many machine-shop laser scanners.”
Question 12

Question 12 Explanation: 
The AKS primality test (also known as Agrawal–Kayal–Saxena primality test and cyclotomic AKS test) is a deterministic primality-proving algorithm created and published by Manindra Agrawal, Neeraj Kayal, and Nitin Saxena, computer scientists at the Indian Institute of Technology Kanpur, on August 6, 2002, in a paper titled "PRIMES is in P". The algorithm was the first to determine whether any given number is prime or composite within polynomial time. The authors received the 2006 Gödel Prize and the 2006 Fulkerson Prize for this work.
Question 13
Self Organizing maps are___
A
A type of statistical tool for data analysis
B
A type of Artificial Swarm networks
C
A type of particle Swarm algorithm
D
None of the above
       Artificial-intelligence       Self-Organizing-Maps
Question 13 Explanation: 
A self-organizing map or self-organizing feature map is a type of artificial neural network that is trained using unsupervised learning to produce a low-dimensional, discretized representation of the input space of the training samples, called a map, and is therefore a method to do dimensionality reduction. Self-organizing maps differ from other artificial neural networks as they apply competitive learning as opposed to error-correction learning (such as backpropagation with gradient descent), and in the sense that they use a neighborhood function to preserve the topological properties of the input space.
Question 14
Hopfield networks are a type of__
A
Gigabit network
B
Terabyte network
C
Artificial Neural network
D
Wireless network
       Artificial-intelligence       Artificial-neural-networks(ANN)
Question 14 Explanation: 
A Hopfield neural network is a type of artificial neural network invented by John Hopfield in 1982. It usually works by first learning a number of binary patterns and then returning the one that is the most similar to a given input. What defines a Hopfield network: It is composed of only one layer of nodes or units each of which is connected to all the others but not itself. It is therefore a feedback network, which means that its outputs are redirected to its inputs. Every unit also acts as an input and an output of the network. Thus the number of nodes, inputs, outputs of the network are equal. Additionally, each one of the neurons in a has a binary state or activation value, usually represented as 1 or -1, which is its particular output. The state of each node generally converges, meaning that the state of each node becomes fixed after a certain number of updates.
Question 15
Sigmoidal feedforward artificial neural networks with one hidden layer can / are ___
A
Approximation any continuous function
B
Approximation any disContinuous function
C
Approximation any continuous function and its derivatives of arbitrary order.
D
Exact modeling technique
       Artificial-intelligence       Artificial-neural-networks(ANN)
Question 15 Explanation: 
Multilayer perceptron class of networks consists of multiple layers of computational units, usually interconnected in a feed-forward way. Each neuron in one layer has directed connections to the neurons of the subsequent layer. In many applications the units of these networks apply a sigmoid function as an activation function.
A feedforward neural network is an artificial neural network wherein connections between the nodes do not form a cycle. As such, it is different from recurrent neural networks. The feedforward neural network was the first and simplest type of artificial neural network devised. In this network, the information moves in only one direction, forward, from the input nodes, through the hidden nodes (if any) and to the output nodes. There are no cycles or loops in the network.

Question 73
Before the printing press, books could be purchased only in expensive manuscript copies. The printing press produced books that were significantly less expensive than the manuscript editions. The public’s demand for printed books in the first years after the invention of the printing press was many times greater than demand had been for manuscript copies. This increase demonstrates that there was a dramatic jump in the number of people who learned how to read in the years after publishers first started producing books on the printing press. Which one of the following statements, if true, casts doubt on the argument?
A
During the first years after the invention of the printing press, letter writing by people who wrote without the assistance of scribes or clerks exhibited a dramatic increase.
B
Books produced on the printing press are often found with written comments in the margins in the handwriting of the people who owned the books.
C
In the first years after the printing press was invented, printed books were purchased primarily by people who had always bought and read expensive manuscripts but could afford a greater number of printed books for the same money.
D
Books that were printed on the printing press in the first years its invention often circulated among friends in informal reading clubs or libraries.
Question 74
Bevex, an artificial sweetener used only in soft drinks, is carcinogenic for mice, but only when it is consumed in very large quantities.

For that reason, Bevex is in fact safe for people.
In order for the conclusion that Bevex is safe for people to be properly drawn, which one of the following must be true?
A
Cancer from carcinogenic substances develops more slowly in mice than it does in people.
B
If all food additives that are currently used in foods were tested, some would be found to be carcinogenic for mice.
C
People drink fewer than 25 cans of Bevex- sweetened soda per day.

Question 77
Many environmentalists have urged environmental awareness on consumers, saying that if we accept moral responsibility for our effects on the environment, then products that directly or indirectly harm the environment ought to be avoided. Unfortunately it is usually impossible for consumers to assess the environmental impact of a product, and thus impossible for them to consciously restrict their purchases to environmentally benign products. Because of this impossibility there can be no moral duty to choose products in the way these environmentalists urge, since_______.
Which one of the following principals provides the most appropriate completion for the argument?
A
a moral duty to perform an action is n ever based solely on the effects the action will have on other people
B
