Because a message to an object causes changes within the object without indicating how the changes should be made, the term "black box" can refer to an object.
When someone sends a message or the person from whom the communication originates does so, communication is said to have begun. The information that is being communicated during the communication process is known as the message. The communication creates a link between the sender and the recipient.
A MESSAGE is, by definition, a collection of data that can be written down (and read), converted into images (and seen or felt), spoken (and heard), captured on video (and seen, heard, and/or read), digitally analyzed (and understood), and so on.
More formal descriptors for messages include speech, email, post, story or article, news item, movie or video, program, show, book, song, and comments or conversation about any of the aforementioned.

Python is an object-oriented, dynamically-semantic, interpreted high-level programming language. Its high-level built-in data structures, along with dynamic typing and dynamic binding, making it particularly appealing for use in rapid application development as well as as a scripting or glue language to join together preexisting components. Python's syntax is also straightforward and quick to learn. Python allows packages and modules, which promotes the modularity and reuse of code in programs. For all popular systems, the Python interpreter and the comprehensive standard library are free to download in source or binary form and can be shared without restriction. Because Python increases efficiency, programmers frequently fall in love with it. The cycle of edit-test-debug is extremely quick because there is no compilation stage. Python scripts are simple to debug because a defect or incorrect input will never result in a segmentation fault. Instead, an exception is raised when the interpreter finds a mistake.

The assignable address range for the 9th subnet will be = 10.8.0.1 to 10.8.255.254
5 is the subnet number for the 6th subnet
Each device has an IP address made up of two parts: the client, also known as the host address, and the server, also known as the network address. A DHCP server or a user must manually configure IP addresses (static IP addresses). The subnet mask divides the IP address into host and network addresses, designating which portion of the address belongs to the device and which to the network. A gateway, also known as the default gateway, joins local devices to other networks. As a result, whenever a local device wants to send data to a device with an IP address on a different network, the gateway receives the packets first and then passes them on to the intended recipient outside of the local network.

An arch, as used in architecture, is any method other than a lintel used to cross an aperture. Curves define true arches. A vault is an arched ceiling or roof made of stone, brick, or concrete; wood or plaster may also be used as an imitation. A dome is a circular base-mounted vault with an equal curvature.
Who developed the arch vault and dome?The Etruscans taught the arch to the ancient Romans, who improved it and were the first architects and builders in Europe to use it to its full potential for structures above ground. The benefits of the arch, the vault, and the dome were fully appreciated by Roman builders before anyone else in Europe or possibly the entire world.
Note that a vault is a brick, stone, or concrete ceiling that is said to be constructed using the arch design principle.

Which of the following programs are command-line programs?
All programs written in IDLE
Programs that are called via CLI
Programs that are called via graphics
Programs that need GUI to execute
Answer: The correct answer is Programs that are called via CLI
Explanation: Command Line Interface applications (CLI) are typically used to call other CLI programs, batch files or command prompt executables. Command-line interfaces are also referred to as command-line user interfaces, console user interfaces, and character user interfaces, though their intended use varies. CLI input can be entered as input commands by the keyboard and then run by the computer.
Answer:
Programs that are called via CLI.
the other options are non-examples because they are a different category of programs (GUI, graphics, and IDLE).

Designed for managing data stored in a relational database management system, SQL is a database language. IBM created SQL for the first time in the early 1970s (Date 1986).
The original SEQUEL (Structured English Query Language) version was created to access and handle data held in IBM's System R quasi-relational database management system. The first SQL implementation to be made commercially available was Oracle V2, which was released for VAX systems in the late 1970s by Relational Software Inc., later to become Oracle Corporation. In this chapter, we'll concentrate on utilizing SQL as a data defining language to build databases and table architectures (DDL).
