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".
Which physical topology uses the same communications line is used to connect all nodes?
logical channel
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.
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.
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.
