Answer:
Following is the code in python language
team_names = ('Rockets','Raptors','Warriors','Celtics')#holding the string value
print(team_names[0],team_names[1],team_names[2],team_names[3])#display
Output:
Rockets Raptors Warriors Celtics
Explanation:
Following is the description of above statement .
- Create a dictionary "team_names" that is holding the string value Rockets Raptors Warriors and Celtics.
- Finally we used the print function in that function we pass the index of corresponding dictionary i.e team_names[0] . it will display the first index value similarly we pass team_names[1], team_names[2] team_names[3].
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: Medium Dependent Interface Crossover (MDIX)
Explanation:
The technology that is typically implemented on switches to avoid Ethernet connectivity problems is Medium Dependent Interface Crossover(MDIX) For switches with Auto (MDIX) the connection is configured automatically and a crossover or straight-through cable can be used to connect two switches. When this MDIX interface is connected it corrects the connectivity speed and the cabling for proper device functionality.

Answer:
Explanation:
There are many weaknesses/vulnerabilities, some of which are the following...
Default Network Hardware, many individuals will go out and buy a new router and install it in their home. These devices come with a preset configuration including a preset security password which is many times a default password used for every router of the same model. This can be easily obtained by anyone who can then access the network.
Access Point hacking, an experienced individual can use a packet sniffer to detect the SSID that is frequently sent from the router in order to create an access point to be able to access the network.
WEP encryption is another vulnerability. These are very low security passwords that can be cracked using different software in a short period of time.
These are some of many vulnerabilities that wireless local networks have, but there are also many precautions and security measures that can be taken to prevent them.
