Question No: 27    ( Marks: 1 )

 What is the Brute Force Strategy?

 

Answer:. A staretegy in which all possible combinations are examined and best among them is selected. Brute force (also known as brute force cracking) is a trial and error method used by application programs to decode encrypted data such as passwords or Data Encryption Standard (DES) keys, through exhaustive effort (using brute force) rather than employing intellectual strategies.

 

 

Question No: 28    ( Marks: 1 )

What is java script?

 

Answer: JavaScript is an object-oriented scripting language used to enable programmatic access to objects within both the client application and other applications.

It is primarily used in the form of client-side JavaScript, implemented as an integrated component of the web browser, allowing the development of enhanced user interfaces and dynamic websites

 

 

Question No: 29    ( Marks: 2 )

 How can you explain control unit?

 

Answer: Control unit is a computerized part of the speech processor. Most of the controls, such as program, volume and sensitivity, are located on the control unit.    

 

Question No: 30    ( Marks: 3 )

 How a designer makes Structured Design?

 

Answer: Structured Design: Materials and member type, size, and configuration to carry loads in a safe and serviceable fashion.

 In general, structural design implies the engineering of stationary objects such as buildings and bridges, or objects that may be mobile but have a rigid shape such as ship hulls and aircraft frames tructural design involves at least five distinct phases of work, project requirements, materials, structural scheme, analysis, and design

It is insufficient in most cases, for the designer to consider a solution, a design. He should evaluate several alternate designs and choose the best in the sense of maximizing such technical objectives as efficiency, reliability, and maintainability while satisfying such design constraints as memory size and response time.

 

Question No: 31    ( Marks: 5 )

What is Turing machine? Who invented it and also explain how a Turing test is conducted?

 

Answer: A Turing machine is a theoretical device that manipulates symbols contained on a strip of tape. Despite its simplicity, a Turing machine can be adapted to simulate the logic of any computer algorithm, and is particularly useful in explaining the functions of a CPU inside of a computer. The “Turing” machine  was designed by Alan Turing in 1937.

The Turing test is a proposal for a test of a machine’s ability to demonstrate intelligence. It proceeds as follows a human judge engages in a natural language conversation with one human and one machine, each of which tries to appear human. All participants are placed in isolated locations. If the judge cannot reliably tell the machine from the human, the machine is said to have passed the test. In order to test the machine’s intelligence rather than its ability to render words into audio, the conversation is limited to a text-only channel such as a computer keyboard and screen.

If a computer pass the test ,we can say that a machine can think.

 

 

Question No: 32    ( Marks: 5 )

 What are JavaScript literal and what are its types?

 

Answer: The raw data that make up the root of data types are called “literals.” These are, in effect, literally what they represent themselves to be. Numbers, strings, and Boolean values make up the core set of literals in JavaScript. Little mystery exists with literals, but important differences exist between them. In JavaScript, data types include strings, which are simply quoted characters, numbers, Boolean, Objects and even a type which has no value at all, Null. Since JavaScript is a loosely typed language, you don’t neccessarily need to know what type of data every value is (although it certainly helps).

Every piece of data in these categories is known as a value. When a value is referred to outright in a statement, it is called a literal value. For the same reason people are identified by names as opposed to “human” or “person”, literal values can be named in order to make repeated reference to them practical, efficent and readable. These names are called variables.

 

Literals can be of several types. Some of them are:

Array Literals

Boolean Literals

Floating-Point Literals

Integers

Object Literals

String Literals
