While logical topology describes how data is moving through the network, physical topology refers to the physical configuration of computer nodes based on the hardware configuration.
Both topologies exist in local area networks (LAN). A secure media connects every node in a LAN to every other node. According to their physical locations, nodes, computers, and other items are connected to one another in a network according to a physical topology.
It is necessary to check the physical setup of network cables and workstations. A logical topology, on the other hand, specifies how information travels between devices when using network protocols. It assesses how devices talk to one another inside.
As a result, network topology explains the virtual form, arrangement, and structure of a network from both a logical and physical standpoint.

Least privilege
Rules-based administration
Open Source Interconnect
The least privilege concept states that administrators should only have the bare minimum of access required to do their duties. This implies that they ought to have two accounts—one for regular work and the other for times when system computer adjustments are required.
The security principle of least privilege is crucial for assuring the reliability and stability of any system. It states that administrators should only have the bare minimum of access required for them to perform their duties. This implies that they ought to have two accounts—one for regular work and the other for times when system adjustments are required. The administrator can prevent the need to make system changes from interfering with their regular work by having two accounts. They can also ensure that the modifications they make can only access the resources required for their job. Administrators can maintain the security of their system and lessen their attack surface by adhering to the least privilege concept. This could aid in limiting access to sensitive information by harmful parties.

a node in a neural network has an activation value of 1.5, and a weight of -0.7. what is the output of that node?
The output of the node can be calculated by taking the dot product of the activation and weight, which is 1.5 * -0.7 = -1.05.
A node in a neural network takes an input value (also known as an activation value), performs a simple computation on that value, and outputs the result. The computation is typically a weighted sum, which is the dot product of the activation and the weights.
In this case, the activation value is 1.5 and the weight is -0.7. The dot product of these two values is 1.5 * -0.7 = -1.05. This means that the output of the node is -1.05.
This value is then passed on as input to the next node in the network, or used as the final output of the network. The weights are adjustable parameters that are learned by the network through training to minimize an error function. The purpose of this is to allow the network to capture complex relationships between inputs and outputs.

If no grounding specifications are available for a cable installation, the grounds should be located at the nearest practical point to the point of cable entry, as well as at aerial pole-mount locations.
Grounding is an important aspect of electrical safety in cable installations. Grounding provides a low-resistance path to safely conduct fault current to the earth, helping to prevent electric shock, fire, and other electrical hazards.
When no grounding specifications are available for a cable installation, it's recommended that the ground be located at the nearest practical point to the point of cable entry, and at aerial pole-mount locations. This ensures that the grounding system is in close proximity to the cable, reducing the potential for high fault current levels in the event of a ground fault.
Additionally, installing a ground at the point of cable entry helps to minimize the resistance in the grounding system, which is critical to the effective operation of electrical safety equipment, such as circuit breakers and ground fault interrupters.

video streaming is designed for use over what transport method?
To stream media over networks, the Real-time Streaming Protocol (RTSP), Real-time Transport Protocol (RTP), and Real-time Transport Control Protocol (RTCP) were created. The latter two are constructed on top of UDP, while RTSP works across a variety of transport protocols.
TCP functions well if your streaming content is captured and made later available to the viewers, such as in the form of VOD. UDP, on the other hand, is commonly used for multicast video conferencing and live streaming. Such applications typically require their own protocol on top of UDP (typically RTP/RTCP over UDP).
Although UDP and TCP differ greatly from one another, we can achieve some TCP-like features by stacking UDP with another protocol. To give one example, if we utilize UDP with the RTCP header, RTP will provide sequence numbers, time stamps, and an identification for the audio or video source in addition to enabling the RTCP protocol to report loss. Additionally, when using RTP with UDP, voice packets are sent with regular spacing based on the output of the codec.
