What is achieved by the encapsulation process at the network layer?
By encapsulation process data is put in a nutshell with all basic protocol information at each and every OSI layer. During this phase of network layer each layer conveys and exchange information to its neighboring layer. This is done utilizing Protocol Data Units.
How osi layer works?
OSI model has seven layers and each layer is assigned a specific task for data transmission process.
What are the steps of encapsulation?
Encapsulation is the process of adding header information to the layers' data "payload". As the "payload" is passed from one TCP/IP (or OSI) layer to the next, encapsulating layer information is wrapped around the data. So, for example, if the application layer produces a data payload for transmission, it encapsulates it with application-layers headers, which then gets passed to the presentation layer. The presentation layer does the same and so down the protocol stack before transmission across the physical media. At the destination, the process is reversed by way of de-encapsulation where the headers are stripped-off by each matching layer at the destination. 1. Application, Presentation and Session layers create data. {Encapsulation headers added by layers} 2. Transport layer coverts data into segments for transport across the network. {Encapsulation headers added by layer} 3. Network layer converts segments into packets (or Datagrams). {Encapsulation headers added by layer} 4. Data Link layer converts packets (and datagrams) into Frames and the Data Link header is added. {Encapsulation headers added by layer} 5. Physical - frames are converted into bits for transmission over the physical media.{Encapsulation headers added by layer}
Which layer of OSI model determines the type of communication?
The OSI model is a general model for networking . It has seven layer in total and each layer have some responsibilities. The layer that determines the communication mode is physical layer.
Which layer of osi model layer Breaks up data into individual containers and assigns each a sequence number?
physical layer
If two switches each support all types of trunk encapsulation on a link between them which type of encapsulation will be negotiated?

What is the purpose of the seven protocols?
I think you are referring to the seven layers of the ISO model. It is a framework that defines the process of moving information from one point to another. That is a complex process with many steps.... too difficult to deal with as one process. The model breaks the process into seven "layers" with each layer defining a part of the process. Each layer defines a result that must be achieved without specifying how to acheive it...so for each layer there can be and are multiple options. The first layer, for instance, requires a method or "protocol" that can transfer a stream of two values (1 and 0) between 2 sites. Any process that can do that is a layer one protocol. Examples include twisted pair wires, microwave, fiber optic, thicknet, thinnet, etc. Layer two describes how to prevent two users from talking at the same time and how to group the ones and zeros into meaningful segments. Token Ring, Ethernet, IPX, etc. Whole books have been written on the subject.
This builds up as layer after layer of sediments pile on top of each other. it is necessary for the process of compaction?

What layer of the OSI model is a Switch on?
It operates on the data link layer of the OSI model (level 2). The switch creates a separate collision domain for each port. Although some switches operate on level 3 of the model and are called multi-layer switches.
What is peer to peer process in osi model?
Protocol layers may be defined in such a way that the communications within a layer is independent of the operation of the layer being being used. This is known as "peer-to-peer" communication and is an important goal of the OSI Reference Model. Each layer provides a protocol to communicate with its peer. When a packet is transmitted by a layer, a header consisting of Protocol Control Information (PCI) is added to the data to be sent. In OSI terminology, the packet data (also known as the Payload) is called a Protocol Data Unit (PDU). The packet so-formed, called a Service Data Unit (SDU) is passed via a service access point to the layer below. This is sent using the service of the next lower protocol layer.
When two computers are exchanging data each OSI model layer on the sending computer can communicate with which other layers?
The layer directly above it The layer directly below it The corresponding layer on the receiving computer
The OSI model and protocols involved in each layer?
Go to the Wiki for OSI model -that discussion and listing is very good.
