Answer:
You need to understand all the network typologies and the devices that we use in the Computer networks. You also use the techniques like routing, masking, firewalls, VPN, as well as the network protocol. And recently added is the PKI. And hence you need to make sure that you know all these, and you should also know ipv4 and ipv6. Rest you can consult Tanenbaum for further studies on Computer Network.

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:
360/number of sides
Explanation:
all the exterior angles add up to 360°
so to find each angle mesure, divide the 360 by the number of sides the figure has.

Here's your answer mate.....☺️☺️
Explanation:
In computer science, digital image processing is the use of a digital computer to process digital images through an algorithm. ... It allows a much wider range of algorithms to be applied to the input data and can avoid problems such as the build-up of noise and distortion during processing.

Answer:
1 2 3 4 5 6 7 8 End
Explanation:
int i = 1;
while (i != 9){
System.out.print (i + " ");
i ++;
if (i == 9){
System.out.println("End");
}
}
