If you save the input as num,
this will print the input 8 times.
num = input("Enter a number: ")
print(num * 8)
If you want to do actual math calculations,
then the input needs to be a number.
num = float(input("Enter a number: "))
print(num * 8)
This doesn't account for any errors in which the user doesn't input a number, but I don't think that's what you were looking for anyway :)
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:
<u> </u><u>Role of websites in internet</u>
- Websites give the online way to the business,it helps the business to grow and reach the higher audience. There was a time,at which there is no apps only HTML/CSS websites are there so it is a building step for reaching the audience.

Yes
Explanation:
Depending on the ethernet standard used, the IEEE 802.3 is faster than the WIFI (IEEE 802.11ac).
The ethernet protocol on cabled networks are of different speed based on ethernet standard which ranges from 10 Mega-bits to 100 Giga-bits per second. This protocol is found in the physical layer of the OSI model.
The wifi 802.11ac also known as wifi 5 is a wireless connection medium in the physical layer of the OSI model. It has a range of aggregate speed capacity of 433 mega-bits per second to 6.77 giga-bits per second.
