(h) To display the Title and Total Price of all Computer books. The Total Price is calculated as Price * Qty. (i) Write the output of the following: (i) Select MIN(Price) from Library; (ii) Select Sum(Price * Qty) from Library where Qty > 3; (iii) Select Avg(Price) from Library where Qty < 4; (iv) Select Count(Distinct Publisher) from Library; Q. 7. Answer the following questions: (a) What is e-Governance? [1] (b) What is e-Learning, how e-Learning will benefit you? [2] (c) Write two advantage of e-Business sites [2]




1. (a) Operating System is defined as a collection of programs that coordinates the operations of computer hardware and software. It acts as a bridge for the interface between man and machine. Examples of Operating System are: Windows, Linux, BOSS etc.

(b) All the physical components of the computer system are said to be as Hardware. For example: keyboard, mouse, monitor, printer etc. Whereas, Software represents the set of programs that govern the operations of a computer system and make the hardware run smoothly.

(c) Virus are the programs that can copy itself and can affect the health of the computer system. Viruses can automatically be transferred from one computer to another when its host is taken to the target computer.

(d) RAM – Random Access Memory. MICR – Magnetic Ink Character Recognition. (e) (i) Fortan, COBOL processor. (ii) Quick Heal, Disk Defrag. (iii) MS Office, Adobe Creative. (iv) Quick Heal, Norton, (f) Compiler converts the high level language

program into machine language in one stroke. Whereas, Interpreter converts the high level language into machine language line by line. It takes one statement at a time of HLL and converts it into machine code.

(g)

System Software Application Software

System software are mandatory for all computer systems to work.

Application software are made to perform the specific task.

For example: Operating Systems like BOSS, Windows and language processors like assembler interpreter and compiler.

For example: Word Pad, MS-Word etc.

2. (a) Byte code is the compiled format for Java programs. Once a Java program has been converted to byte code, it can be executed by Java Virtual Machines (JVM).

(b) Text field allows the user to enter single line of text only, whereas text area component allows accepting multiple line input from the user.

(c) ‘x’ indicates that this value is a single character and can be stored by a variable having the data type as char. Whereas, “x” indicates that even though it’s a single character, but it is going to be stored in the variable having data type as String.

(d) When the value does not matches with any case of switch statement then the statements written in default case are executed.

(e) Program maintenance can be defined as the modification of the program after delivery to improve its performance and to make it more reliable to handle the updated needs and emerging threats.

(f) The loop in which test condition is checked in the beginning of the loop, are known as entry controlled loop. For Example: while loop. Whereas, when statements inside the loop body is executed and then the condition is checked that loop is known to be as exit controlled loop. For Example: do-while loop.

(g) class factorial { public static void main(String args[ ]) {int n, c, fact = 1; System.out.println(“Enter an integer to

calculate it’s factorial”); Scanner in = new Scanner(System.in); n = in.nextInt(); if (n < 0) System.out.println(“Number should be non-

negative.”); else { for (c = 1; c <= n; c++) fact = fact*c; System.out.println(“Factorial of “+n+” is =

“+fact); } } } 3. (a) DESC Employee; (b) It helps the users to delete the record from the

Table. (c) The Char data-type stores fixed length strings.

If a string to be stored in a field having length smaller than the field size then padded on the right is done automatically before being stored.

Whereas, Varchar supports variable length strings and therefore if the string to be stored is smaller than the field size it stores without modification. And hence, it saves memory.

(d) In a table primary key is an attribute which is used to identify the records uniquely. A table can have multiple unique keys, but only 1 of them is the primary key.




(e) SQL commands can be classified into following categories:

(i) Data Definition Language(DDL): They are used to define the structure of tables and other objects in a database. For example: CREATE, ALTER, DROP, TRUNCATE, RENAME.

(ii) Data Manipulation Language(DML): They are used to manipulate and access the data in the database. For Example: SELECT, INSERT, UPDATE, DELETE, LOCK TABLE.

(iii) Transaction Control Language(TCL): Used to manage transactions in the database. They are also used to manage the changes done by DML statements. For Example: COMMIT, SAVEPOINT, ROLLBACK, SET TRANSACTION.

(iv) Data Control Language(DCL): These commands are often used by Database Administrators and are considered as expert level commands because they are used to assign security levels in a database. Also, they are used to grant and define role and access privileges to the users. For Example: GRANT, REVOKE.

(f) ALTER TABLE emp ADD email VARCHAR(20); 4. (a) As there is no statement of input is given in the

question. Hence, it should be a tricky question. As by default when we declare an integer in Java, it stores the value 0(zero). Hence, the value of val=0.

(i) Output: 200 (ii) Output: 200 (b) 17. (c) int sum, value, incr; int I; for ( i=0; i<=10; i++) sum+=I; incr++; (d) int sum=0, i=1; while(i<=5) {sum=sum+c; i++; } (e) int Ch; Ch=Integer.parseInt(ChTextField.getText()); switch(Ch) { case ‘1’ : System.out.println(“Arts”); break; case ‘2’: System.out.println(Commerce); break; case ‘3’: System.out.println(Science);

break; default: System.out.println(Invalid Entry); } (f) (i) Code Snippet: float CostDisc, TotalDisc, temp, cost,

discountoncost, disountoncategory; cost= Integer.parseInt(txtCost.getText()); if(cost<=1000) discount on cost=.05; else discount on cost=0.10; if (rebtn1. is Selected( )) discount on category=.03; else { if (rebtn2. is Selected( )) discount on category=.02; else discount on category=.03; } Cost Disc=cost*discount on cost; temp=cost*discount on category; TotalDisc=CostDisc + temp; txt Discount.setText (TotalDisc); (ii) txt Discount.setEditable(False); (iii) System. exit(0); 5. (a) ALTER command with MODIFY command

should be used for this purpose. (b) In My SQL, the empty values are represented as

NULL in a table. When we perform arithmetic calculations to a NULL value it will still remain null because mathematical operations cannot be performed on NULL value.

(c) My SQL is Structured Query Language based open source Data Base Management System. Two features of MySQL are:

(i) Cross-Platform support. (ii) Free to download and use. (d) USE employee; (e) (i) 86. (ii) driya vidy (iii) IPL20 (iv) INFORMATICSPRACTICES (f) In SQL ORDER BY command is used to sort the

results of the query. Syntax: ORDER BY column name sorting

mechanism; For Example: SELECT Salary FROM Employee

ORDER BY Salary DESC; The above statement will display the Salary

of Employees in descending order from table Employee.

(g) COMMIT command is used to make changes permanent.




6. (a) SELECT Title FROM LIBRARY WHERE (Price BETWEEN 100 AND 300);

(b) SELECT Title, Author FROM LIBRARY WHERE (Subject=’Prog’ AND Publisher=‘PBP’);

(c) SELECT * FROM LIBRARY WHERE Price>130 ORDER BY QUANTITY ASC;

(d) SELECT * FROM LIBRARY WHERE Quantity<4;

(e) SELECT Publisher, Quantity FROM LIBRARY; (f) INSERT INTO LIBRARY VALUES (11,’Question

Bank’, ‘Expert’, ‘IP’, ‘Oswaal Books’,10,150); (g) UPDATE LIBRARY, SET Price = Price+30

WHERE Title = ‘TURBO C++’; (h) SELECT Title, Price*Quantity FROM LIBRARY; (i) (i) 40.00 (ii) 1620 (iii) 143 (iv) 7 7. (a) It refers to application which provides

electronic solution for governance to fulfil the requirements of common man in least possible time at affordable costs.

(b) e-learning describes as a means of teaching and learning through e-technology like Internet

and multimedia, CD ROM or DVD. Some advantages of e-Learning are:

(i) It provides faster learning at low cost. (ii) Makes learning easy because student don’t

have burden of creating notes in class, they can concentrate on understanding the concepts.

(iii) It makes learning very easy as it typically along with written paragraphs they also contain audio and videos.

Some mostly used websites for e-Learning are: www.teachlearnweb.com, www.byjus.com. www.meritnation.com, www.extramarks.com

(c) Some benefits of e-Business are: (i) It reduces cost of production. (ii) Everyone can access the market with

comfort at home. (iii) It increases transparency of prices. (iv) Major companies provides 24/7 customer

service which is best for the users. (v) Easy orders cancellation and refund

process.

SOLU-TIONS

1. (a) Arithmetic Logic Unit. (b) Basic Input/Output System, Bharat Operating System Solutions. (c) 1024 GB. (d) A firewall is used for network security. Its objective is to control the incoming as well as outgoing traffic by

analysing the data packets and determining that it should be sent/received or not. A firewall can be software as well as hardware based.

(e) (i) Google Chrome. (ii) WinRAR. (iii) Netbeans. (iv) MySQL. (f) (i) Virus is a program with malicious intention to corrupt important files and data. Worm is self-replicating program that expands itself with every program run and eat up all the memory

and make system crash. (ii) Biometrics or sometimes called biometric authentication is referred to the identification of humans by

their traits or characteristics like retina, DNA scan, finger prints. Biometrics is used in computer science as identification and access control.

2. (a) (i) 92_xy is invalid identifier because an identifier cannot start with a numeric character. (ii) int amount=400;

amount-=50;

(b) (i) False. (i) Note: This is a tricky question. Because, in programming there is nothing like 3x. It is valid in algebra but

in the terms of programming it should be written as 3*x. Hence, this statement will give error. (c) (i) In Implicit type conversion conversion java compiler converts all operands up to the type of largest

datatype. For example: int i=4;

double K = 2*2.5+i;

Whereas , in explicit type conversion, conversion is user defined that forces an expression to be of specific data type converting it explicitly.

For example: double d=4.25;

int i= (int)d;

3. (a) A relation is a table with columns and rows which represent the data items and relationships amongst them. (b) MySQL and MSSQL. (c) (i) Degree refers to the number of columns and cardinality refers to the number of rows in a table. If R is a

relation with 7 rows and 6 columns, then Degree: 6 and Cardinality: 7. (ii) • USE school; • SHOW TABLES; • SELECT * FROM student; • DROP student. (d) (i) In a table primary key is an attribute which is used to identify the records uniquely. Sometimes combination

of more than one attributes are declared as primary key, in that case primary key is known as composite key.

(ii) • Exam • 355.9 • abcpqxy • FITTNESS




4. (a) He can use setEditable( ) method for this purpose. (b) Frame, Window. (c) jTextField is typically used to take input from the user. Whereas, jLabel is used to make the application more

understandable using proper identification terms and names for the controls. It can be said that jLabel is somewhat non-editable jTextField.

(d) (i) switch (ch) {

case 1: counta++;

{

sum+=i;

++i;

}

OR int num=20,i=1;

long sum=0;

do

{

sum+=i;

++i;

} while(i<num);

(f) (i) jTextField2.setEditable(false); jTextField5.setEditable(false);

if(rMale.isSelected())

overtime=hours*100;

if(rFemale.isSelected())

overtime=hours*125;

jTextField4.setText(overtime);

jTextField5.setText(overtime + wages);

5. (a) The Char data-type stores fixed length strings. If a string to be stored in a field having length smaller than the field size then padded on the right is done automatically before being stored.

Whereas, Varchar supports variable length strings and therefore if the string to be stored is smaller than the field size it stores without modification. And hence, it saves memory.
