1. A socket is a connection point that enables a two-way communication between programs running in a network.

This statement is true because a socket is a software structure that serves as an endpoint for sending and receiving data across a network. A socket is defined by an application programming interface (API) for the networking architecture, such as TCP/IP.A socket can be used to establish a communication channel between two programs running on the same or different network nodes12.

2. A socket is always the secure means by which computers on a network can safely communicate, without the risk of exposure to an attack.

This statement is false because a socket by itself does not provide any security or encryption for the data transmitted over the network. A socket can be vulnerable to various types of attacks, such as eavesdropping, spoofing, hijacking, or denial-of-service.To ensure secure communication, a socket can use additional protocols or mechanisms, such as SSL/TLS, SSH, VPN, or firewall3.

3. A socket is a connection point that enables a one-way communication only between remote processes.

This statement is false because a socket can enable both one-way and two-way communication between processes running on the same or different network nodes. A socket can be used for connection-oriented or connectionless communication, depending on the type of protocol used.For example, TCP is a connection-oriented protocol that provides reliable and bidirectional data transfer, while UDP is a connectionless protocol that provides unreliable and unidirectional data transfer12.

4. A socket can be used to establish a communication endpoint for processes running on the same or different machines.

This statement is true because a socket can be used for inter-process communication (IPC) within a single machine or across different machines on a network.A socket can use different types of addresses to identify the processes involved in the communication, such as IP address and port number for network sockets, or file name or path for Unix domain sockets12.

Option A is true because PEP 8 recommends that function and variable names should be lowercase, with words separated by underscores .

Option D is true because PEP 8 recommends that constants should be written in all capital letters with words separated by underscores .

PEP 8 is the official style guide for Python code. It provides guidelines for how to write readable code that follows consistent naming conventions. The aim of PEP 8 is to improve the readability of Python code and make it easier to understand and maintain.

According to PEP 8, variable and function names should be written in all lower-case letters with words separated by underscores, as stated in A. Constants, which are variables whose value is expected to remain constant throughout the code, should be written in all upper-case letters with words separated by underscores, as stated in D.

The json.dumps() function is used to convert a Python object into a JSON string1. It takes Python data as its argument, such as a dictionary or a list, and returns a JSON string.

1. It returns a JSON string.

This statement is true because the json.dumps () function takes a Python object as its argument and returns a JSON-formatted string that represents the object. For example, json.dumps ([1, 2, 3]) returns '[1, 2, 3]'.

1. The sqlite3 module in python provides an interface compliant to the DB-API 2.0. Thus, it follows a standard performance metric that allows for consistency in database programming with python.

2. The special name 'memory' is used to create a database in RAM using the sqlite3 module. Thus, when you use it as the name of the database file while opening a connection, it creates a temporary database that exists only in memory.

The@propertydecorator should be defined after the method that is responsible for setting an encapsulated attribute is a false sentence. In fact, the@propertydecorator should be defined before the method that is used to set the attribute value. The@propertydecorator and the setter and deleter methods work together to create an encapsulated attribute, which is used to provide control over the attribute's value.

Official Python documentation on Property:https://docs.python.org/3/library/functions.html#property

The@propertydecorator is used to designate a method as a getter for an instance attribute. The method decorated with@propertyshould be defined before any setter or deleter methods for the same attribute.
