The link can accommodate a maximum of eight users. In circuit-switching, each user requires a permanent allocation of user-bandwidth on the link.
What exactly is MBPS?The unit of measurement for broadband speeds is megabits per second, also known as Mbps or Mb Mbits p/s. A megabit is one million bits, which are extremely small data pieces. The more Mbps (megabits per second) we have available, the faster your internet activity should be.
Although 100 Mbps is a fast internet speed, it is not very fast. It's barely above average for the vast majority of online users. While 100 Mbps is more than enough for streaming, gaming, and Zoom, some users require much faster internet.
Download speeds of at least 100 Mbps and upload speeds of at least 10 Mbps are considered adequate. With 100 Mbps, you can stream online, participate in online meetings, and do other things.

There are two types of cell references: absolute and relative. Relative and absolute references behave in different ways when copied and entered into other cells. When a formula is copied to a different cell, its relative references are changed. In contrast, absolute references are valid everywhere they are used. By default, all cell references are relative references. When reproduced across numerous cells, they alter based on the relationship between rows and columns. For instance, if you move the formula from row 1 to row 2, =A1+B1 will become =A2+B2. Relative references must be used if the same calculation is repeated.

how do the four main oop principles (inheritance, encapsulation, abstraction, and polymorphism) work together to make a well-designed application? how do they allow a programmer to create more reusable and maintainable code?
In Java, there are four primary OOP concepts. They are: Abstraction. Using simple things to represent complexity is known as abstraction.
Even though we all know how to turn on the television, we don't need to understand how it works to enjoy it. In Java, "abstraction" refers to simple things like "objects," "classes," and "variables" that represent code and data that are more intricate beneath. This is important because it lets you avoid doing the same thing over and over again.
Encapsulation. This is the practice of making fields in a class private and then making public methods available to access them. It acts as a barrier that protects the code and data within the class. We are able to reuse objects like variables and code components in this manner without permitting widespread access to the system's data.
Inheritance. In Java, this is a unique feature of Object Oriented Programming. It makes it possible for programmers to create brand-new classes that share a few of the characteristics of existing classes. We are able to build on previous efforts without having to start from scratch.
Polymorphism. Programmers can use the same word to mean different things in different situations thanks to this Java OOP concept. Method overloading is one Java polymorphism type. That's when the code itself starts to mean different things. Method overriding is the other type. When the values of the provided variables are considered, the various meanings become apparent.

As a result, isolationism is fundamentally opposed to joining military alliances and mutual defence treaties. In its purest form, isolationism opposes all relationships with other nations, including treaties and commercial agreements.
This distinguishes isolationism from non-interventionism, which also promotes military neutrality but does not always oppose treaties and international agreements in general. a strategy or doctrine that seeks to keep one's country out of the affairs of other countries by refusing to join alliances, make foreign investments, sign international treaties, and generally strive to make one's economy completely self-sufficient; it seeks to focus all of one's country's efforts on its own development.

You are in a cement room with no windows and doors and you have a piece of wood and a mirror. How will you escape?
It is not possible to escape the cement room with only a piece of wood and a mirror as these items do not have the ability to create an opening in the walls or floor of the room.
The mirror could be used to signal for help by reflecting sunlight or other light sources if any available, but it would not provide a means of escape. The piece of wood could be used as a tool to break the mirror and create a signal for help, but it would not provide a means of escape.
In this case, it would be best to find another way to signal for help, such as making noise or using the mirror to reflect light to a nearby window or door.
It would also be important to stay calm and think critically about the situation in order to find any potential weaknesses or hidden exits in the room. Additionally, it would be important to remember that there might be some emergency exit or a phone, in the room to contact the authorities.
