a. If n2 is not even, then the integer n is not even.
b. Let us assu,e that √7 is a rational number.
√7 =a/b, where a and b are co-prime, i.e., a and b have no common factors. Squaring we have,
7b2 = a2 ⇒ 7 divides a.
∴ Let a = lk
∴a2= 49k2  ⇒ 7b2= 49k2 ⇒ b= 7k⇒7  divides b.
i.e., 7 divides both a and b, which is contradition to our assumption that a and b have no common factor. our supposition is wrong.
∴ √7 is an irrational number.

a. Coefficient of variables
b. Standard Deviation
Standard Deviation: is the positive square root of the mean of squared deviations from mean.
So if there are five values X1, X2, X3,X4and X5, first their mean is calculated. Then devia­tions of the values from mean are calculated. These deviation are then squared. The mean of these squared deviations is the variance. Positive square root of the variance is the standard deviation.

Answer 25.
During 1972 -2010 there was a movement of workless from casual wage to self-empl­oyment.

Answer 26.
It refers to the development strategy to inte­rruption till the resource extraction was not above the rate of regeneration of the resource and the wastes generated were within the assimilating capacity of the environment But today, environment fails to perform its third and vital function of the substance resulting in an environmental crisis. The rising popula­tion of the developing countries and the af­fluent consumption and production stand­ards of the developed world have placed huge stress on the environment in terms of its first two functions.

Strategies for sustainable Development.

1. Use of a non-conventional source of energy: – India heavily, depends on the hydropower plants to meet its power needs. Both of the­se have adverse environmental impacts. Thermal power plants emit large quantities of carbon dioxide, which is a greenhouse gas. It is not used properly.

2. Bio-Composting:-Inorder to increase pro­duction, we have started using chemical fertilisers which are adversely affecting the waterbodies, groundwater system, etc. But again farmers in large numbers have started using organic fertilisers for production.

3. Mini-Hydel Plants:- Mountainous region have streams everywhere, Most of such streams are perennial. Mini-hydel plants use the energy of such streams to move small turbines which generates electrici­ty. Such power plants are more or less envi­ronment friendly.

4. Traditional Knowledge and Practices:- Traditionally, Indian people have close to their environment. If we look back at our agriculture system, healthcare system, ho­using, transport, etc we find that all prac­tices have been environment-friendly.

5. Biopest Control:-With the advent of Gre­en Revolution, the country entered into the use of chemical pesticides to produce more which laid the adverse impacts on soil, wa­ter bodies, milk, meat, and fishes. To meet this challenge, better methods of pest control should be brought. One step is pesti­cides based on plants like neem. Even many animals also help in controlling pests like snakes, peacocks, etc.

6. CNG in Urban Areas:- In Delhi, the use of Compressed Natural Gas as fuel in the public transport system has significantly low­ered air pollution and the air has become cleaner in the last few years.

(a) Domain = [-4,4]
Range = [0,4]
(b) x2 + y2=16
y2= 16-x2
y= \(\sqrt { 16-{ x }^{ 2 } } \)
i.e.,f (x)= \(\sqrt { 16-{ x }^{ 2 } } \)

Answer 12.
(a) 8
(b) P(n):1 + 3 + 32 + ……..3n-1 =\(\frac { { 3 }^{ n }-1 }{ 2 } \)
Let P(1): 1 =\(\frac { { 3 }^{ 1 }-1 }{ 2 } \)=2/2=1
Hence, P(1) is true.
P(k): 1 + 3 + 32 +…… + 3k-1=\(\frac { { 3 }^{ k }-1 }{ 2 } \)
To prove that P(k+1) is true. P(k+1):
1 + 3 +32 + + 3i_1 +3k+1-1 =\(\frac { { 3 }^{ k+1 }-1 }{ 2 } \)
⇒ P(k)+3k = \(\frac { { 3 }^{ k+1 }-1 }{ 2 } \)
⇒ \(\frac { { 3 }^{ k }-1 }{ 2 } \) + 3k= \(\frac { { 3 }^{ k+1 }-1 }{ 2 } \)
= \(\frac { { 3 }^{ k }-1 }{ 2 } \) + 3k= \(\frac { { { 3 }^{ k } }-1+2\times { 3 }^{ k } }{ 2 } \)
Now, LHS = \(\frac { { { 3\times 3 }^{ k } }-1 }{ 2 } \) =  \(\frac { { 3 }^{ k+1 }-1 }{ 2 } \) = RHS
Hence, P(k+1) is true.
Hence, P(n) is true for all n∈N

Answer 15.
Let the equation of the circle be
(x – h)2 + (y – k)2 = r2
Since the circle passes through (4, 1) and (6,5), we have
(4-h)2 + (1 -k)2 = r2……….. (1)
and (6 -h)2 + (5 – k)2 = r2………… (2)
Also since the centre lies on the line 4x + y = 16, we have
4h + k = 16…………. (3)
Solving the equations (1), (2) and (3), we get
h = 3 and k = 4
(4 – 3)2 + (1 – 4)2 = r2
r2=10
Hence, the equation of the required circle is
(x-3)2+1 (y-4)2= 10
x2-6x + 9 + y2-8y + 16-10 = 0
x2 + y– 6x –  8y + 15 = 0

(a) 10 [Z coordinate of the point]
(b) Let P(4,0,0) be a line on the X-axis.
distance = \(\sqrt { { (4-4) }^{ 2 }+{ (8-0) }^{ 2 }+{ (10-0) }^{ 2 } } \)
= \(\sqrt { 64+100 } =\sqrt { 164 } =2\sqrt { 41 } \)
(c) Since the line segment divided the YZ plane, its x coordinate is zero.
So =\(\frac { { mx }_{ 1 }+{ nx }_{ 1 } }{ m+n } \)
⇒ mx2 + nx1=0
\(\frac { m }{ n } =\frac { { -x }_{ 1 } }{ { x }_{ 2 } } =\frac { -2 }{ 3 } \)
⇒m : n=-2 : 3

Answer 17.
(a) 275 is a perfect square,
(b) Let -√2 is rational.
\(\sqrt { 2 } =\frac { p }{ q } \) , p and q have no common factor.
p2 = 2q2
i.e., 2 divides p2 is 2 divides p
∴ p = 2k, p2 = 4k2
2q2 = 4k2, q2 = 2k2
2 divides q2 is 2 divides q.
p and q have a commonfactor 2.

1. Shard web hosting:
It is the most common type of web hosting. It is referred to as shared because many different wesites are stored on one single web server and they share resources like RAM and CPU. The features available on shared web servers are generally basic and are not flexible to suit a website that require specific features.
2. Dedicated web hosting:
It is the hosting where the client leases the entire web server and all its resources. The web server is not shared with any other website. Dedicated servers provide guaranteed performance, but they are very expensive. Since the bandwidth is not shared with other websites, it speeds up the access of the website. If the client is allowed to place their own purchased web server in the service providers facility, then it is called co-location.
3. Virtual Private Server (VPS):
It is a physical server that is virtually partitioned into several servers using the virtualization technology. Each VPS works similar to a dedicatd server and has its own separate server operating system, web server soft-ware and packages. VPS provides dedicated amount of RAM for each virtual web server. Each of these VPS works as a fully independent web server. VPS are provided with the rights to install and configure any software on their VPS.

2. Logical level:
It is the next higher level of abstraction describes what data is stored in the database, and what relation¬ship exist among those data. It describes : the entire database in terms of a small i number of relatively simple structures. The user of the logical level does not need to ‘ be aware of the complexity. Logical level ; is also referred as conceptual level.
3. View level:
It is the highest level of data-base abstraction and is closest to the users. It is concerned with the way in which 5 individual users view the data. It describes J only a part of the entire database. Most of i the users are not concerned with all the information that is contained in the data-base.

The following steps illustrate how the DNS resolves the IP address:

  • All browsers store the IP addresses of the recently visited websites in its cache. Therefore, the browser first searches its local memory (mini cache) to see whether it has the IP address of this domain. If found, the browser uses it.
  • If it is not found in the browser cache, it checks the operating system’s local cache for the IP address.
  • If it is not found there, it searches the DNS server of the local ISP.
  • In the absence of the domain name in the ISP’s DNS server, the ISP’s DNS server initiates a recursive search starting from the root server till it receives the IP address.
  • The ISP’s DNS server returns this IP address to the browser.
  • The browser connects to the web server using the IP address of website and the webpage is displayed in the browser window. If the IP address is.not found, it returns the message ‘Server not found’ in the browser window.

Answer:
Advantages of DBMS (Any Three)
1. Data Redundancy: It means duplication of data. DBMS eliminates redundancy. DBMS does not store more than one copy of the same data.

2. Inconsistency can be avoided: If redundancy occurs there is a chance to inconsistency. If redundancy is removed then inconsistency cannot occur.

3. Data can be shared: The data stored in the database can be shared by the users or programs.

4. Standards can be enforced – The data in the database follows some standards.
Eg: a field ‘Name’ should have 40 characters long. Some standards are ANSI, ISO, etc.

5. Security restrictions can be applied – The data is of great value so it must be kept secure and private. Data security means the protection of data against accidental or intentional disclosure or unauthorized destruction or modification by an unauthorized person.

6. Integrity can be maintained: It ensures that the data is to be entered in the database is correct.

7. Efficient data access: It stored a huge amount of data efficiently and can be retrieved whenever a need arise.

8. Crash recovery: Sometimes all or a portion of the data is lost when a system crashes. A good DBMS helps to recover data after the system crashed.

Question 26.

(c) ASP, JSP, PHP, etc.

Question 30.
In JavaScript:
(a) Explain any three types of operators used.
(b) Describe any two datatypes used.
Answer:
(a) Operators in JavaScript: Operators are the symbols used to perform an operation

  1. Arithmetic operators: It is a binary operator. It is used to perform addition(+), subtraction(-), division(/), multiplication(*), modulus(%-gives the remainder)
  2. Assignment operator: If a = 10 and b = 3 then a = b. This statement sets the value of a and b are the same, i.e. it sets a to 3.
  3. Logical operators: Here AND(&&), OR(||) are binary operators and NOT(!) is a unary operator. It is used to combine relational operations and it gives either true or false

b) Data types in JavaScript: Unlike C++ it uses only three basic data types

  1. Number: Any number(whole or fractional) with or without a sign.
    Eg: +1977, -38.0003, -100, 3.14157,etc
  2. String: It is a combination of characters enclosed within double-quotes.
    Eg: “BVM”, “[email protected]”, etc
  3. Boolean: We can store either true or false. It is case sensitive. That means can’t use TRUE OR FALSE

Question 23.
Explain three types of “Web hosting”.
Answer:
Types of web hosting
Various types of web hosting services are available. We can choose the web hosting services according to our needs depends upon the storage space needed for hosting, the number of visitors expected to visit, etc.

1) Shared Hosting: This type of hosting shares resources, like memory, disk space, and CPU hence the name shared. Several websites share the same server. This is suitable for small websites that have less traffic and it is not suitable for large websites that have large bandwidth, large storage space, and have a large volume of traffic.
Eg: Shared hosting is very similar to living in an Apartment(Villas) complex. All residents are in the same location and must share the available resources(Car parking area, Swimming pool, Gymnasium, playground, etc) with everyone.

2) Dedicated Hosting: A web server and its resources are exclusively for one website that has a large volume of traffic means a large volume of requests by the visitors. Some Govt, departments, or large organizations require uninterrupted services for that round the clock power supply is needed. It is too expensive but it is more reliable and provides good service to the public.
Eg: It is similar to living in an Our own house. All the resources in your house are only for you. No one else’s account resides on the computer and would not be capable of tapping into your resources.

3) Virtual Private Server (VPS): A VPS is a virtual machine sold as a service by an Internet hosting Service. A VPS runs its own copy of an OS(Operating System) and customers have super level access to that OS instance, so they can install almost any s/w that runs on that OS. This type is suitable for websites that require more features than shared hosting but less features than dedicated hosting.
Eg: It is similar to owning a Condo

Question 24.
Distinguish Alternate key and foreign key.
Answer:
Alternate key – A candidate key other than the primary key.
Foreign key – A single attribute or a set of attributes, which is a candidate key in another

Question 25.
Explain the different levels of data abstraction in DBMS.
Answer:
Levels of Database Abstraction:

  1. Physical Level (Lowest Level) – It describes how the data is actually stored in the storage medium.
  2. Logical Level (Next Higher Level) – It describes what data are stored in the database.
  3. View Level (Highest level) – It is closest to the users. It is concerned with the way in which the individual users viewthe data.

Question 26.
Explain any three-column constraints in SQL.
Answer:
Constraints are used to ensure database integrity.

  1. Not Null – It ensures that a column can never have NULL values.
  2. Unique – It ensures that no two rows have the same value in a column.
  3. Primary key – Similar to unique but it can be used only once in a table.
  4. Default- We can set a default value.
  5. Autojncrement – This constraint is used to perform autoincrement of the values in a column. That automatically generates serial numbers. Only one autoincrement column per table is allowed.

Question 27.
Consider the table ITEM with the field Item code, Item name, Price, Write SQL queries.

  1. To Display the maximum and minimum price of items.
  2. To remove all records where priced < 1000
  3. To display the number of records in the table.

Answer:

  1. select max(Price), min(Price) from ITEM;
  2. delete from ITEM where Priced<1000;
  3. select count(*) from ITEM;

Implementation denotes how variables are declared, how functions are coded, etc. It is through interface (function header/function signature) a communication is send to the object as messages.
Encapsulation: An OOP concept that binds together the data and functions that manipulate the data, and keeps both data and function safe from outside interference and misuse. C++ implements encapsulation through the declaration of a class. A class can contain private, protected and public members.
Polymorphism refers to the ability of a programming language to process objects differently depending on their data type or class. More specifically, it is the ability to redefine methods for derived classes.

Answer 19.
Algorithm: To perform DELETION operation in a queue
Consider an array QUEUE[N], where N is the maximum size of the array. FRONT and REAR keeps track of the front and rear position of the queue. VAL is a variable to be removed from the queue.

Start
1: If (FRONT > -1 AND FRONT < REAR) 
Then // empty status checking 
2: VAL = Q[FRONT]
3: FRONT = FRONT + 1 
4: Else
5: Print “Queue underflow”
6: End of If
7: If (FRONT > REAR) Then 
8: FRONT = REAR = -1 
9: End of If 
Stop

Answer 20.
1. Border: It specifies the thickness of the border line around the table.
2. Bordercolor: It is used to assign colour to the table border.
3. Align: It specifies the position of the table inside the browser window.

Answer 21.

  1. Inside <BODY>: Placing scripts inside the <BODY> tag, the scripts will be executed while the contents of the web page is being loaded. The web page starts displaying from the beginning of the document. When the browser sees a script code in between, it renders the script and then the rest of the web page is displayed in the browser window.
  2. Inside <HEAD>: It is a visual practice to include scripts in the head section of the web page. The main reason for this is that the body section of most of the HTML pages contains a large volume of text that specifies the contents to be displayed on the web page. Mixing a function definition also with this will create a lot of confusion for the web designer for making any kind of modification in the page.
  3. External JavaScript file: We can place the scripts into an external file and then link to that file from within the HTML document. This file is saved with the extension ‘.js’. Placing JavaScripts in external files has some advantages. This is useful if the same scripts is used across multiple HTML page or a whole website.

Answer 22.
Web hosting is the service of providing storage space in a web server to serve files for a website to be made available on the Internet.
The two stages of web hosting are:
1. Purchase of hosting space.
2. Registration of domain name.
Two types of web hosting are:
Shard web hosting: It is the most common type of web hosting. It is referred to as shared because many different websites are stored on one single web server and they share resources like RAM and CPU. The features available on shared web servers are generally basic and are not flexible to suit a website that require specific features. Dedicated web hosting: It is the hosting where the client leases the entire web server and all its resources. The web server is not shared with any other website. Dedicated servers provide guaranteed performance, but they are very expensive. Since the bandwidth is not shared with other websites, it speeds up the access of the website. If the client is allowed to place their own purchased web server in the service
providers facility, then it is called co-location.

Answer 23.
1. Physical level: It is the lowest level of abstraction. The physical level describes complex lowlevel data structures in detail. We must decide what file organisations are to be used to store the relations and create auxiliary data structures, called indexes, to speed up data retrieved operations.
2. Logical level: It is is the next higher level of abstraction describes what data is stored in the database, and what relationship exist among those data. It describes the entire database in terms of a small number of relatively simple structures. The user of the logical level does not need to be aware of the complexity. Logical level is also referred as conceptual level.
3. View level: It is the highest level of database abstraction and is closest to the users. It is concerned with the way in which individual users view the data. It describes only a part of the entire database. Most of the users are not concerned with all the information that is contained in the database.

Answer 24.
a. UNIQUE
b. AUTO_INCREMENT
c. NOT NULL

Answer 25.
a. First case: Indexed array
Second case: Associative array

b. $arr1 = array(12, 36, 29, 34, 48);

Answer 26.
Distributed computing is a method of computing in which large problems can be divided into many small problems which are distributed to many computers. It provides a way to reduce the time it takes to perform a large task.
Grid computing is described as a world in the computational power (resources, services, data) is readily available. Here users get access to computational power just like electricity through wall side with no care or consideration for where or how the electricity is actually generated. Computers on a grid have a program on them, that allows unused resources to be used by another computer on the grid.
Cluster computing is a form of computing in which a group of personal computers, storage devices etc. are linked together so that they can work like a single computer. The components of a cluster are connected to each other through fast local area networks. Clusters provide computational power through parallel processing. It is relatively low cost form of a parallel processing machine used for scientific and other applications.

Answer 6.
If the memory allocated using new operator is not freed using delete, that memory is said to be an orphaned memory block -a block of memory that is left unused, but not released for further allocation. Remedy for memory leak is to ensure that the memory allocated through new is properly deallocated through delete. Memory leak takes place only in the case of dynamic memory allocation. But in case of static memory allocation, the operating system takes the responsibility of allocation and deallocation without user’s instruction. So there is no chance of memory leak in static memory allocation.

Answer 7.
C++ provides facility to define new data types by which such aggregate or grouped data can be represented. The data types defined by user to represent data of aggregate nature are generally known as user-defined data types. Structure is a user-defined data type which represents a collection of logically related data items. It can represent a group of different types .of data under a common name.

Answer 8.
Once the stack is full, and if we attempt to insert an item, an impossible situation arises. This is known as stack overflow.
If the stack is empty and we try to delete an item from the stack, an unfavorable situation arises. This is known as stack underflow.

Payment gateway is a server that acts as a bridge between merchant server and bank server and transfers money in an encrypted format whenever an online payment/money transfer is made.

Answer 10.
Operator + is used to add two strings. Adding two string means concatenating two strings. If the operands are numbers, it will add the numbers. If the operands are strings it will concatenate the strings. If + operator sees any one operand as string, it will treat both the operands as string type and concatenate the strings.

Answer 11.
It is a visual practice to include scripts in the head section of the web page. The main reason for this is that the body section of most of the HTML pages contains a large volume of text that specifies the contents to be displayed on the web page. Mixing a function definition also with this will create a lot of confusion for the web designer for making any kind of modification in the page. Moreover, the head section of a web page is loaded before the body section. Therefore, if any function call is made in the body section, the function will be executed as the function will be executed as the function definition is already loaded in the memory.

Answer 12.
The rows which are to be deleted are selected by using the WHERE clause. If the WHERE clause is not used, all the rows in the table will be deleted.

Answer 13.
It performs an auto-increment feature. By default, the starting value for this constraint is 1 and will be incremented by 1 for each new record. Only one AUTO_INCREMENT column per table is allowed.

Answer 17.
1. Since there is no size specification, a string of any number of characters can be stored. There is no wastage or insufficiency of memory space. But it should be done with initialization, (e.g., char *str = “Program”;)
2. Assignment operator (=) can be used to copy strings.
3. Any character in the string can be referenced using the concept of pointer arithmetic which makes access faster.
4. Array of strings can be managed with optimal use of memory space.

Answer 18.
C++ implements encapsulation and data hiding through the declaration of a class. A class can contain private, protected and public members.

Private: By default, all items defined in a class are private. Members declared under private section are not visible outside the class.

Protected: Members declared as protected are visible to its derived class, but not outside the class.

Public: All variables or functions defined after the public access specifier are accessible anywhere in our program.

Answer 19.
In linked list, traversal begin from the first node. The pointer Start gives the address of the first node, so that we can access the data part using arrow (->) operator. Then we access the link part of the first part, which is the address of the second node. Using this address, we can access the data and link of the second node. This process is continued until we found NULL pointer in the link of a node.

Software as ab Service (SaaS): It gives subscribers access to both resources and applications. Here a complete application is offered to the customer, as a service on demand. Consumers purchase the ability to access and use and an application or service that is hosted in the cloud.

Platform as a Service (PaaS): A PaaS system goes a level above the software as a Service setup. A PaaS provider gives subscribers access to the components that they require to develop and operate applications over the internet. The customer has the freedom to build his own applications, which run on the provider’s infrastructure.

Infrastructure as a Service (IaaS): In this, as the name states, deals primarily with computational infrastructure. IaaS provides basic storage and computing capabilities as standardized services over the network. The customer would typically set up his own software on the infrastructure.

a. It is a cyber attack against sensitive computer networks like nuclear power plants, air traffic controls, gas line controls, telecom, etc. These types of attacks against governments are increasing globally. Cyber terrorism focuses on the use of the internet by anti-nationals to affect a nation’s economic and technological infrastructure. It may prove to be very costly to a country. Therefore governments provide very powerful security mechanisms for their servers.
b. This is a common cyber attack against a government. Defacement of websites includes hacking of government websites and posting derogatory comments about a government in those websites.
c. These types of attacks deny a particular online government service. This is done using a Distributed Denial of Service (DDoS) attack. They gain access to website administration through content management system and destroy the data. This causes huge loss to the government.

Answer 28.
These are applied only to individual columns. They are written immediately after the data type of the column. They are:

  • NOT NULL: It specifies that a column can never have NULL values. NULL is a keyword that represents an empty value.
  • Two NULL values cannot be added, subtracted and compared.
  • AUTO_INCREMENT: It performs an auto-increment feature. By default, the starting value for this constraint is 1 and will be incremented by 1 for each new record. Only one AUTO_ INCRE-MENT column per table is allowed.
  • UNIQUE: It ensures that no two rows have the same value in the column specified with the constraint.
  • PRIMARY KEY: It declares a column as the primary key of the table. It is similar to UNIQUE except that it can be applied only to one column or combination of columns. The primary keys cannot contain NULL values.
  • DEFAULT: A default value can be set for a column, in case the user does not provide a value for that column of a record.

Answer 29.
Domain names are used to identify a website in the Internet. After finalizing a suitable domain name for our website, we have to check whether this domain name is available for registration or its is already in use by somebody else. The websites like www.whois .net check the database of ICANN that contain the list of all the registered domain names. If the domain name entered is available, we can proceed with the registration. The registration requires filling information for WHOIS database of domain names for ICANN. WHOIS information requires the name, address, telephone number and e-mail address of the registrant. After paying the annual registration fees online, the domain is purchased and is registered in our name. Our domain name has to be connected to the IP address if the web server where the web pages are stored. This is done using ‘A record’ (Address record) of the domain. An ‘A record’ is used to store the IP address of a web server connected to a domain name. The ‘A record’ can be modified by logging into the control panel of the domain.

Question 7.
What is the difference between static and dynamic memory allocation?
Answer:
We know that memory is classified into two primary and secondary. Just like that data structures are classified as static and dynamic. Static data structure is associated with primary memory. The needed memory is allocated before the execution of the program and it is fixed throughout the execution. The array is an example of this. In a Dynamic data structure, memory is allocated during execution. A linked list is an example of this.
