III. Short Answer Questions

Question 1.
What are the disadvantages of Cooperatives? (Any 3)
Answer:
1. Limited funds:
Since the co-operative societies have limited membership and it is promoted by the weaker section, the membership fees collected is low. They cannot expand their activities beyond a particular level due to the limited financial resources.

2. Over-reliance on Government funds:
Co-operative societies are not able to raise their own resources. Their sources of financing are limited and they depend on government funds. The funding and the number of funds that would be released by the government are uncertain.

3. Conflicts among members:
Cooperative societies are based on the principles of co-operation and therefore harmony among members is important. But in practice, there might be internal politics, differences of opinions, quarrels, etc. among members which may lead to disputes. Such disputes affect the functioning of cooperative societies.

EXTRANET:
It is a private network that uses Internet technology and the public telecommunication system to securely share business information with suppliers, vendors, partners, customers, or other businesses.

Question 2.
Discuss OSI model with its layers.
Answer:
OSI Model

  • Open System Interconnection (OSI) model was found in the year 1934, a general framework that enables network protocols along with software and systems to be developed based on a general set of guidelines.
  • It describes the standards for the inter-computer communication.

OSI Layers:
1. Physical Layer:

  • It is the 1st layer.
  • It defines the electrical and physical specifications for devices.

2. Data Link Layer:

  • It is the 2nd layer.
  • It guarantees that the data transmitted are free of errors.
  • This layer has simple protocols like “802.3 for Ethernet” and “802.11 for Wi-Fi”.

3. Network Layer:

  • It is the 3rd layer.
  • It is used to determine the path of the data packets.
  • At this layer, routing of data packets is found using IP Addressing.

4. Transport Layer:

  • It is the 4th layer.
  • It guarantees the transportation/sending of data is successful.
  • It includes the error checking operation.

5. Session Layer:

  • It is the 5th layer
  • It is used to identify the established system session between different network entities.
  • It controls dialogues between computers.
  • For instance, while accessing a system remotely, the session is created between your computer and the remote system.

6. Presentation Layer:

  • It is the 6th layer.
  • It does the translation of data to the next layer (Prepare the data to the Application Layer). Encryption and decryption protocols occur in this layer such as Secure Socket Layer (SSL).

7. Application Layer:

  • It is the 7th layer.
  • It acts as the user interface platform comprising software within the system.

Demerits of Mobile Networks:

  1. Cost
  2. Vulnerable to security risks.
  3. Additional training is needed to use new technology.
  4. Cybercrime

Development:
The generations of mobile networks are as follows.

  1. First Generation (1G) 1981 – NMT Launch
  2. Second Generation (2G) 1991 – GSM Launch
  3. Second to Third Generation Bridge (2.5)2000 – GPRS launch
  4. Third Generation (3G) 2003 – first UK 3G launch
  5. Fourth Generation (4G) 2007
  6. Fifth Generation (5G) 2019+

1. First Generation (1G) 1981 – NMT launch:

  • During the initial periods, the mobile systems were based on analog transmission.
  • NMT stands for Nordic Mobile Telephone communication.
  • And a very poor voice quality.

2. Second Generation(2G) 1991-GSM Launch:

  • Later the second generation of mobile systems was placed on digital transmission with GSM.
  • GSM stands for (Global System for Mobile communication) was the most popular standard which is used in the second generation, using 900MHz and 1800MHz for the frequency bands.
  • The transfer mission used as TMDA stands for (Time Division Multiple Access) and CDMA One stands for (Code Division Multiple’Access) method to increase the amount of information transported on the network

3. Second to Third Generation Bridge (2.5)2000 – GPRS launch:

  • GPRS was introduced here GPRS stands for (General Packet Radio Service).
  • GPRS is a data service which enables mobile devices to send and receive messages, picture messages, and e-mails.
  • GSM data transfer mission rates typically reached 9.6kbit/s.

4. Third Generation( 3G) 2003- first UK 3G launch:

  • This generation of mobile systems merges different mobile technology standards and uses higher frequency bands for transfer mission and Code Division Multiple Access to deliver data rates of up to 2Mbit/s supports multimedia services (MMS: voice, video, and data).
  • The data transfer mission used a WCDMA. WCDMA stands for (Wideband Code Division Multiple Access).
  • Few 3G suppliers use ATMs (Asynchronous Transfer Mode) for their ‘over the air’ network within MPLS (Multiprotocol Label Switching) or IP for their backbone network.

5. Fourth Generation (4G) 2007:

  • 4G is at the research stage. 4G was based on an Adhoc networking model where there was no need for a fixed infrastructure operation.
  • Adhoc networking requires global mobility features (e.g. Mobile IP) and connectivity to a global IPv6 network to support an IP address for each mobile device.
  • Logically roaming in assorted IP networks (for example 802.11 WLAN, GPRS and UMTS) were be possible with higher data rates, from 2Mbit/s to 10-100Mbit/s, offering reduced delays and new services.

6. Fifth Generation (5G) 2019+:

  • 5G is the stage that succeeds the 4G (LTE/ WiMAX), 3G(units), and 2G(GSM) systems.
  • 5G targets to performance the high data rate, reduced latency, energy saving, cost reduction, higher system, capacity, and massive device connectivity.
  • The ITU IMT – 2020 provides speeds up to 20 gigabits per second it has been demonstrated with millimeter waves of 15 gigahertz and higher frequency.

Detailed Answers

Question 1.
Explain in detail about Second Generation of Mobile Networks.
Answer:

  • The second generation of mobile systems was placed on digital transmission with GSM.
  • GSM stands for (Global System for Mobile communication)was the most popular standard which is used in the second generation, using 900MHz and 1800MHz for the frequency bands.-
  • GSM mobile systems have grown digital transmission using SIM. SIM stands for (Subscriber Identity Module) technology to authenticate a user for identification and billing purposes and to encrypt the data to prevent listen without permission (eavesdropping).
  • The transmission used as TDMA. TMDA stands for (Time Division Multiple Access) and CDMA One stands for (Code Division MultipleAccess ) method to increase the amount of information transported on the network.
  • Mobility is supported at layer 2, which stops seamless roaming across assorted access networks and routing domains. This means each operator must cover the entire area or have agreements in place to permit roaming.

Question 2.
Explain the important protocols present in

  1. Network layer
  2. Transport Layer

Answer:

1. Network Layer:
It is the layer where data is addressed, packaged, and routed among networks.
The important Internet protocols that operate at the Network layer are:

  • Internet Protocol (IP): A routable protocol which uses IP addresses to deliver packets. It is an unreliable protocol, does not guarantee the delivery of information.
  • Address Resolution Protocol (ARP): Resolves IP addresses to MAC (Medium Access Control) addresses. (A MAC address is a hardware identification number that uniquely identifies each device on a network.)i.e., to map IP network addresses to the hardware addresses.
  • Internet Control Message Protocol (ICMP): Used by network devices to send error messages and operational information. Example: A host or router might not be reached or requested service is not presented.
  • Internet Group Management Protocol (IGMP): It is a communication protocol used by hosts and routers to send Multicast (group Communication) messages to multiple IP addresses at once.

2. Transport Layer: The sessions are recognized and data packets are swapped between hosts in this layer.
Two main protocols established at this layer are:

  • Mission Control Protocol (TCP): Provides reliable connection-oriented Transmission between two hosts. It ensures the delivery of packets between the hosts.
  • User Datagram Protocol (UDP): Provides connectionless, unreliable, one-to-one, or one-to-many delivery.

Question 3.
Write short notes on Fourth Generation of Mobile Networks
Answer:

  • 4G is at the research stage. 4G was based on an Adhoc networking model where there was no need for a fixed infrastructure operation.
  • Adhoc networking requires global mobility features (e.g. Mobile IP) and connectivity to a global IPv6 network to support an IP address for each mobile device. Logically roaming in assorted IP networks (for example 802.11 WLAN,
  • GPRS and UMTS) were possible with higher data rates, from 2Mbit/s to 10-100Mbit/s, offering reduced delays and new services.
  • Mobile devices will not expect on a fixed infrastructure, they will require enhanced intelligence to self-configure in ad-hoc networks and having routing capabilities to route over packets switched network.

Question 4.
Explain about Fifth Generation of Mobile Networks
Answer:

  • 5G is the stage that succeeds the 4G (LTE/WiMAX), 3G(UMTS), and 2G(GSM) systems.
  • 5G targets to performance the high data rate, reduced latency, energy saving, cost reduction, higher system, capacity, and massive device connectivity.
  • The two phases of 5G, First one will be Release-15 complete by March 2019, Second one Release- 16is expected to complete in March 2020, for submission to the ITU (International Telecommunication Union) as a candidate IMT- 2020 technology.
  • The ITU IMT – 2020 provides speeds up to 20 gigabits per second it has been demonstrated with millimeter waves of 15 gigahertz and higher frequency. 3 GPP standards include any network using the New Radio software. 5G New Radio can access at lower frequencies from 600 MHz to 6 GHz.
  • Speed in the lower frequencies is only modestly higher than 4G systems, estimated at 15% to 50% faster.

Samacheer Kalvi 12th Computer Applications Guide Chapter 9 Connecting PHP and MYSQL

Question 3.
Explain in details types of MySQL connection method in PHP.
Answer:
Open a Connection to MySQL
There are several methods for connecting to a MySQL database using PHP:

  • MySQL Improved (mysqli) extension
  • PDO (PHP Data Objects)
  • Legacy MySQL (mysql_) functions
  • Connecting to a remote MySQL database using PHP

Connecting to MySQL using the MySQL Improved extension
The MySQL Improved extension uses the mysqli class, which replaces the set of legacy MySQL functions.

Connecting to MySQL using PDO (PHP Data Objects)

  • The MySQL Improved extension can only be used with MySQL databases.
  • PDO, on the other hand, abstracts database access and enables you to create code that can handle different types of databases.

Connecting to MySQL using the legacy MySQL functions

  • The original PHP MySQL functions (whose names begin with mysql_) are deprecated in PHP 5.5, and will eventually be removed from PHP.
  • Therefore, you should only use these functions when absolutely necessary for backward compatibility.
  • If possible, use the MySQL Improved extension or PDO instead.

Connecting to a remote MySQL database using PHP

  • The previous examples all assume that the PHP script runs on the same server where the MySQL database is located.
  • But what if you want to use PHP to connect to a MySQL database from a remote location.
  • For example, you may want to connect to your A2 Hosting database from a home computer or from another web server.

Question 4.
Explain MySQLi Queries with examples.
Answer:
Performing Queries:
The main goal of MySQL and PHP connectivity is to retrieve and manipulate the data from MySQL database server. The SQL query statements are helping with PHP MySQL extension ^to achieve the objective of MySQL and PHP connection. “mysqli_query” is a function, helps to execute the SQL query statements in PHP scripting language.

Syntax:
mysqli_query(“Connection Object” “SQL Query”)
Example:
$con=mysqli_connect(“localhost”,“my_user”,“my_password”,“Student_DB”); $sql=“SELECT student_name,student_age FROM student”;mysqli_query($con,$sql);

Closing Connection:
mysqli_close( ) Function is used to close an existing opened database connection between. PHP scripting and MySQL Database Server.

Syntax:
mysqli_close(“Connection Object”);
<?php
$con=mysqli_connect(“localhost”,“$user”,“$password”,“SCHOOLDB”);
// ….some PHP code… mysqli_close($con);
?>

Example of PHP and MySQL Program:
<?php .
$servemame = “localhost”;
$usemame = “username”;
$password = “password”;
$dbname = “schoolDB”;
$connection = mysqli_connect(“$servemame”, “$usemame”, “$password” “$dbname”);
if (mysqli_connect_error ( ))
{
echo “Failed to connect to MySQL:”
mysqli_connect_error( );
}
sql stmt = “SELECT * FROM mycontacts”; //SQL select query
$result = mysqli_query($connection,$sql_stmt);//execute SQL statement$rows =
mysqli__num_r°ws($result);// get number of rows returned
if($rows) {
while ($row = mysqli_fetch_array($result)) {
echo ‘ID:’. $row[‘id’]. ‘<br>’;

Question 6.
What is meant by Mitakshara Law?
Answer:
Mitakshara is one of the schools belonging to Hindu law. The Mitakshara is a legal treatise on inheritance, written by Vijnaneshwara a scholar in the Western Chaiukya court in the 12th century. It became one of the most influential texts in Hindu law, and its principles regarding property distribution, property rights, and succession are still in practice across most of India except for West Bengal and Assam where the Dayabhaga system is practiced.

A salient feature is the principle of division of ancestral property held by. the Hindu joint family. Partition of such landholding among offsprings is possible even with the father still living, unlike the Dayabhaga system. Inheritance is based on the principle of propinquity i.e.‘the nearest in blood relationship will get the property. The system of devolution of property is by survivorship. The share of coparceners in the joint family property is not definite or ascertainable, as their shares are fluctuating with births and deaths of the coparceners.

Answer:

While loopFor Each loop
Working principleThe while statement will execute a block of code If and as Song as a test ex­pression, is true.The foreach statement is used to loop through arrays.
Working principleIf the test expression is true then the code block will be executed. After the code has executed the test expression will again be evaluated and the loop will continue until the test expression is found to be false.For each pass, the value of the current array element is assigned to $value and the array pointer is moved by one and in the next pass, the next element will be processed.
