Answer: True
Explanation: In data mining, they use statistics component for the analyzing of the large amount of data and helps to deal with it. Statistics provide the techniques for the analyzing, evaluating and dealing with the data that is known as data mining.Data statistics provide the help to organize large data in a proper form and then analyze it. Thus, the statement given is true that data mining must use statistics to analyse data.
Answer:
Class is the correct answer for the above question.
Explanation:
In an object-oriented language, The class is a structure type template, which is used to define the structure but the class does not take memory when an object is created then it takes the memory of class type. For example, if a user-defined class of one member whose size is 4 bit if its store in memory. When a user creates an object, then the object size is 4 bit.
That's why the class is an only structure while an object is used to give the memory for class member and the member of the class also get executed by the object of that class. class have no existence if object is not created. so when a user wants to create a object, he needs to create the object by the help of class name because class is user defined data type and object is variable of that class.
Then the answer of the above question is that object is created with the help of class which is described above.
Answer:
A.
Explanation:
A Joystick is a control device that is connected to the computer to play games. A joystick is similar in structure to a control stick used by pilots in airplanes and got its name from the same. A joystick contains a stick, base, extra buttons, auto switch fire, trigger, throttle, POV hat, and a suction cup. A joystick also serves the purpose of assistive technology.
The device which can not be used in MS Office is a joystick. Therefore, option A is correct.
No, it is not necessary that variables that contain numbers should always be declared as integer or floating-point data types.
It is not necessary that variables that contain numbers should be declared as integer and floating point data types. Because number can be declared with different data types. As we know that data type is a vital aspect in programming. It describes the type of a value that is contained in a variable. It is the data type based on which memory is allocated to a number or any type of variables.
Numbers can be whole decimal/fractional, signed, unsigned, small, and long. Simply, they exist in a variety of values. According to their values range, the amount of memory is reserved.
Different programming languages offer different data types to store numbers, depending on their types and size. Let’s consider some examples of data types used in programming languages in order to declare variables holding numbers.
- In Python int, float, and complex are the data types used to declare number type variables.
- SQL uses INTEGER, SMALLINT , BIGINT , NUMERIC() , and DECIMAL() data types for numbers.
- To deal with number type variables, Java has six predefined data types, such as int, long, short, byte, float, and double.
- JavaScript uses a single data type called 'number' to declare numbers.
- In C++, two fundamental data types, int and float, are used to represent numeric variables. But C++ is not only limited to these two data types. The data type char can also store numbers. Other data types for declaring numbers as variables are derived from int, float and char, such as short int, long int, signed int, unsigned int, double, long double, signed char, unsigned char etc. etc.
So in concluding remarks, declaring a number type variable is not only limited to using integers and floating-points data types. Rather it entirely depends on the respective programming language, and size and type of the number to be stored in the variable.

Answer:
To get the IP address and other information on the workstation, type 'ipconfig' for windows or 'ifconfig' or Linux and press the return key.
The subnet mask is a class B type and 169.254.14.11 IP address shows that the workstation cannot access the DHCP server, so the IP address is not properly configured for network connection.
Explanation:
A computer network is an interconnection and intercommunication of two or more computer devices. All devices in a network must have an IP address, which can be static or dynamic from a DHCP server.
When a computer is configured to receive IP address from a DHCP server, but cannot reach the server, the IP address from the range of 169 is automatically assigned to it but still would not be able to communicate with other devices in the network.
