Question Discussion & Solution

The correct answer is Select, where, group by, having.

Additional Information

Six Operations to Order: SELECT, FROM, WHERE, GROUP BY, HAVING, and ORDER BY. Because the database executes query components in a specific order,

SELECT select_list [ INTO new_table ]  [ FROM table_source ]

[ WHERE search_condition ]

[ GROUP BY group_by_expression ]

[ HAVING search_condition ]

[ ORDER BY order_expression [ ASC | DESC ] ]

Hence Option 4 is correct

The correct answer is Mode of Nutrition.

• In 1969, R.H. Whittaker introduced the five-kingdom system of classification.
• In the five-kingdom system, the basis of classification is the complexity of cell structure, physical organization, nutrition method, and life cycle.
• Aristotle firstly divided the living world into two groups, namely, flora and fauna.
• After that, in his book 'Systema Naturae', Linnaeus classified all animals into plants and animals.
• Linnaeus is called the 'father of modern classification system'.

Additional Information

• Whittaker classified all creatures in the following five kingdoms -

1. Kingdom Monera-
   • ​​This world consists of prokaryotic organisms ie Bacteria, Cyanobacteria, and Archaebacteria.
2. Kingdom Protista-

• This world consists of unicellular eukaryotic organisms. Yuglina, which is situated between plants and animals, is included in this world.

3. Kingdom Fungi-

• This includes organisms dependent on parasites and dead food for food. Their cell wall is made of chitin.

4. Plant World (Kingdom Plantae)-

• This world consists of algae and multicellular green plants.

5. Kingdom Animal-

• This includes all multicellular animals. It is also called 'Metazoa'.

Concept

The eight primitive data types supported by the Java programming language are:

• byte: The byte data type is an 8-bit signed two's complement integer. It has a minimum value of -128 and a maximum value of 127 (inclusive). 

• short: The short data type is a 16-bit signed two's complement integer. It has a minimum value of -32,768 and a maximum value of 32,767 (inclusive).

• int: By default, the int data type is a 32-bit signed two's complement integer, which has a minimum value of -231 and a maximum value of 231-1. In Java SE 8 and later, you can use the int data type to represent an unsigned 32-bit integer, which has a minimum value of 0 and a maximum value of 232-1. .

• long: The long data type is a 64-bit two's complement integer. The signed long has a minimum value of -263 and a maximum value of 263-1. In Java SE 8 and later, you can use the long data type to represent an unsigned 64-bit long, .

• float: The float data type is a single-precision 32-bit IEEE 754 floating point.

• double: The double data type is a double-precision 64-bit IEEE 754 floating point. For decimal values, this data type is generally the default choice. 

• boolean: The boolean data type has only two possible values: true and false. 

• char: The char data type is a single 16-bit Unicode character. It has a minimum value of '\u0000' (or 0) and a maximum value of '\uffff' (or 65,535 inclusive).

Hence there are 8 primitive data types, that is, byte, short, int, long, float, double, boolean and char

Additional Information

Non-primitive data types - such as String, Arrays, ArrayList, Integer, Long,  etc.

The correct answer is Software program.

• An operating system is system software that manages computer hardware, software resources, and provides common services for computer programs. Operating systems are found on many devices such as a computer, mobile phones, video games etc.
• Software program
  • It is a set of instructions, or a set of modules or procedures, through which computer operation is performed.
  • It is often called a software application and a software product.

Additional Information

• Computer system
  • A Computer system is usually defined as a combination of both hardware and software working together.
  • Hardware is the physical components of a computer and software is the programs that run on a computer.
• Network
  • It is a collection of computers, servers, mainframes, network devices, peripherals, or other devices connected to one another to allow the sharing of data.
  • E.g - The Internet, often referred to as the ‘Net’, consists of a complex network of computers connected by high-speed communication technologies like satellites, microwave devices, etc.
• Hardware device
  • Computer hardware includes the physical parts of a computer, such as a case, central processing unit (CPU), monitor, mouse, keyboard, computer data storage, graphics card, sound card, speakers and motherboard.
  • It accepts the data (input) from the user.
  • The computer has memory chips, which are designed to hold data until it is needed.
  • It processes this data into information. The computer has an electronic brain called the Central Processing Unit, which is responsible for processing all data into information according to the instructions given to the computer.
  • It then returns the processed information (output) to the user.

Table and chair both are made of wood

Similarly, shoes and belt both are made of Leather.
