Topology
While geometry is primarily concerned with the mathematical properties of spatial objects, topology is concerned with the mathematical properties of those objects under continuous deformations. Please post all questions about topological subjects like homeomorphisms, manifolds, convergence, and connectedness, as well as their broad applications in computing, physics, and graph theory, into this category.

an isometric sketch is a 3D drawing of different regular prisms that are often drawn on isometric dot paper isometric sketches are useful for planing enginering basic items.
Are weight and mass he same thing?
No. The relationship is:
weight = mass x gravity
Mass causes both weight, and inertia. Weight is the force of attraction by gravity, and also depends on the gravitational field, not just on the mass.
For more information, check the Wikipedia article "Mass versus weight".
Where to use hierarchical topology?
Hierarchical topology is best used in large organizations or data centers where scalable and efficient network management is essential. It organizes network components into layers, typically comprising core, distribution, and access layers, facilitating better performance, ease of troubleshooting, and easier implementation of policies. This structure is ideal for environments requiring high availability, redundancy, and effective traffic management. Additionally, it supports various types of devices and services, making it suitable for complex networking needs.
Which physical topology uses the same communications line is used to connect all nodes?
logical channel
What components does a ring topology require?
A ring topology requires several key components: network devices (such as computers and printers) that are connected in a circular fashion, a network interface card (NIC) in each device to enable communication, and cabling to connect each device to its two adjacent devices in the ring. Additionally, a token-passing mechanism may be used to control data transmission, ensuring that only one device sends data at a time to prevent collisions. This setup allows for efficient data transfer but can be disrupted if any single device or connection fails.
What are the protocols used in a bus topology?
In a bus topology, data transmission typically uses protocols such as Ethernet, specifically the Carrier Sense Multiple Access with Collision Detection (CSMA/CD) protocol. This protocol allows devices to detect when the bus is free and transmit data while monitoring for collisions. If a collision occurs, devices stop transmitting and wait for a random time before attempting to resend. Other protocols, like Token Ring, can also be adapted for bus topologies, but CSMA/CD is the most common.
Why is it important to understand the presence of bias?
Understanding the presence of bias is important because it allows us to critically evaluate information and make informed decisions. Bias can influence the way we perceive and interpret information, leading to unfair judgments or decisions. By being aware of bias, we can strive for more objective and just outcomes in various aspects of our lives.
What are the advantages and disadvantages of internal bus?
The advantages of an internal bus include simplicity and cost-effectiveness, as it allows for direct communication between components within a computer without the need for additional hardware. It can also enhance performance by facilitating faster data transfer between the CPU, memory, and other components. However, the disadvantages include potential bottlenecks, as multiple devices sharing the same bus can lead to congestion and slower performance. Additionally, the limited bandwidth of the internal bus can restrict the overall system performance, especially in data-intensive applications.
What is the circumfrance of a circle that is 50ft in diameter?
The formula for the circumference of a circle is π x d (diameter).
Solution: C= π x d; C=3.1416 x 50; C=157.08 feet or 157 feet (rounded to nearest whole number).
What makes polyester make it better than other plastics?
Polyester is favored for its durability, strong fibers, and resistance to shrinking and stretching. It is also less prone to wrinkling compared to other plastics, making it a popular choice for clothing and textiles. Additionally, polyester is moisture-wicking and dries quickly.
What companies using the bus topology?
Bus topology is less common in modern networking due to its limitations, but it is still used by some small businesses and educational institutions for simple local area networks (LANs). Companies that require straightforward setups and have limited budgets may utilize bus topology for connecting devices like computers and printers in a single line. However, it's important to note that larger organizations typically opt for more robust topologies, such as star or mesh, to enhance reliability and performance.

What is the common network of bus topology?
The common network of bus topology is a network where clients are connected through cables called a bus. You can learn more about this at the Wikipedia. Once on the website, type "Bus network" into the search field at the top of the page and press enter to bring up the information.
Does a physical network topology specify connectivity methods?
No, physical connections are OSI layer 2 connections and shouldn't specify any higher-level connectivity. Ideally you should still try to draw them in hierarchical order (core, distribution & access).
Where can one find information on tree topology?
You can find information on tree topology in networking textbooks, online resources such as websites, forums, and tutorials, and through professional courses or certifications in networking. Additionally, attending networking conferences or webinars can also provide insights into tree topology and its applications in networking.
