OSI (Open Systems Interconnection) is a standard description or "reference model" for how messages should be transmitted between any two points in a telecommunication network. Its purpose is to guide product implementors so that their products will consistently work with other products. The reference model defines seven layers of functions that take place at each end of a communication. Although OSI is not always strictly adhered to in terms of keeping related functions together in a well-defined layer, many if not most products involved in telecommunication make an attempt to describe themselves in relation to the OSI model. It is also valuable as a single reference view of communication that furnishes everyone a common ground for education and discussion.

Which model of supervision do you prefer as a teacher?
As a teacher, I prefer a collaborative model of supervision where there is a partnership between the supervisor and teacher. This allows for open communication, feedback, and professional growth through a supportive relationship.
What is meant by air to open valve?
An increase in air pressure to the actuator is required to cause the valve to open. This is called Air-to-Open Valve. Otherwise normally called Fail-Closed or Normally Closed Valve. An increase in air pressure to the actuator is required to cause the valve to close. This is called Air-to-Close Valve. Otherwise normally called Fail-Open or Normally Open Valve. Another way of looking at these definitions are: When air is given from the bottom of the diaphragm, the stem will go up and flow enters from the input and flows to the output. This is called Air-to-Open. When air is given from the top side of the diaphragm, the stem will go down and the stem will close the plug into the seat, meaning that the flow would be shut-off and the valve will be closed. Basically, you need air to either open or close the valve to allow your flow to proceed or shut.
What is this method of teaching called?
This method of teaching is called the Socratic method. It involves the use of open-ended questions to stimulate critical thinking and encourage active participation from students.
Why are private schools called public?
Private schools are called public in some countries like the UK because they are open to the public, but require payment for attendance. The term "public" distinguishes them from schools that are exclusive to certain groups, such as religious or military institutions.
How do you introduce values to students?
Introduce values to students by incorporating them into discussions, activities, and examples that are relevant and relatable to their lives. Encourage open dialogue, reflection, and critical thinking to help students understand the importance of values and how they can be applied in various situations. Model the values you want to teach and provide opportunities for students to practice them in real-life scenarios.
Why Osi model is a model not a protocol?
because osi is open system interconnection that used to interact with open system
Which layer of the OSI model is the data link layer?
Open system interconnection is the general networking model. Open system interconnection model is introduced by ISO . Physical layer is the first layer of OSI model.Data link layer is the second layer of OSI model. Data Link Layer, this layer is where we actually assign meaning to the electrical signals in the network.
Which osi layer is application?
OSI stands for Open system interconnection model. Application layer is the seventh layer in OSI model.
What is osi in computer networking?
OSI means Open System Interconnection. OSI is a standard model for networking given by ISO .
What does OSI stand for?
OSI stand s for open system interconnection. It is a networking model given by ISO. It is introduced so that systems can communicate with each other regardless of their underlying architecture.
What is Open systems interconnection model?
is an abstract description for layered communications and computer network protocol design. It was developed as part of the Open Systems Interconnection (OSI) initiative. ...
What are set of rules that computers must follow to transmit data electronically is called?
The Open Systems Interconnection model (OSI model), which has 7 layers.
Why is the OSI model still being used?
The Open Systems Interconnection model is a conceptual model that characterizes and standardizes the internal functions of a communication system is used for interoperability and layered .hence,it is used.
What is the most common method for illustrating the operations of a networking stack is the which consist of layers?

Which layer of the OSI model are layers capabale of functioning?
The OSI Model stands for Open Systems Interconnection. The answer to the question which layer of the OSI model are layers capable of functioning is at all layers.
Explain OSI model?
The Open Systems Interconnection model (OSI model) was a product of the Open Systems Interconnection effort at the International Organization for Standardization. It is a way of sub-dividing a communications system into smaller parts called layers. Similar communication functions are grouped into logical layers. A layer provides services to its upper layer while receiving services from the layer below. On each layer, an instance provides service to the instances at the layer above and requests service from the layer below.For example, a layer that provides error-free communications across a network provides the path needed by applications above it, while it calls the next lower layer to send and receive packets that make up the contents of that path. Two instances at one layer are connected by a horizontal connection on that layer.
