Let us see about the Fiber optic cable's characteristics. Transmission rate is really high and very good in case of light transmission. It can move that is travel through long distance without nay electrical interference. Data type such as voice, video can also be sent with the help of this. This is a secured media that guarantees security features. It is very difficult to maintain.
Generally fiber optic cable is a light pipe. This is the way in which a light beams used to transfer all the data’s from one place to another. Transmitting the data via this is very easy. Light is an electromagnetic signal. Everything depends on the frequency of light and nothing more than this. But when it comes to repairing cost, it really costs high when compared to the other.
Now, Let us see about the conductors that are used to connect the co-axial cable. Coaxial cable connectors are also known as BNC connectors. Usually we can see this coaxial cable for giving a cable TV connection, Ethernet networks and more. These connectors are very good and give more life to the networks.
Now let us see about the Coaxial cable in detail. As I have already told you that coaxial cable belongs to Bounded or guided media. As said it consists of a hollow outer layer that acts as a conductor. It surrounds a single inner wire conductor .you can transmit both analog and digital signals with the help of coaxial cable.
The transmission medium can be mainly classified into two types.
1. Bounded or guided media
considering the Bounded or guided media you can see a lot of sessions inside the cable. wire is bounded with many layers. it protects everything and guard the wire. Twisted pair cable and Coaxial cable are its types.
2. Unbounded or un-guided media.
heer there will be no sessions. you cannot find any protection layer or multipe layer in this kind of Unbounded or un-guided media. Microwave links or radio links and Infrared are some of its types.
Hi friends! This is about the Transmission media. We all know the importance of transmission layer. Without the transmission medium you cannot do anything. You cannot even receiver or send the data. Transmission media uses different kind of physical medium to transfer data between the receiver and sender. Fiber optic cable and co-axial cable are generally used.
Application layer is nothing but the network virtual. This is the virtual representation of data. This can be done by the user. User interface is done here. Receiving and sending of e-mail can be done here, sharing the database can be done, transfer of data can be done and a lot of facilities are there with the application layer. You can use all these features.
These are the functions of the layer called presentation layer. Translation, encryption and compression are very important. We have already seen about the syntax and the sessions. Now here it is very important to say that the above process called syntax and semantics deals with the presentation layer. Encryption is nothing but the encoding of data. Compression is nothing but making the data in the short form without losing the details and the meaning.
Let us see about the session layer is network controller. Sessions are very important as they are responsible for the proper sending and receiving of data. Each and every session is very important as they contain the data parts. If one session fails then the data will be totally collapsed and the process will become incomplete. So each and every session should be properly sent and received.
The transport layer is responsible for the delivery of data from one place to another. To get a proper transfer of data it is very important to maintain the transport layer. If all the layers works properly and the transport layer fails, then that's all. You cannot do anything with that transfer of data. So we should maintain the errors and the process in the controlled way. Flow of data should also be maintained. It is much important that connection should be checked at all time during transfer of data. So take care.
Packets are nothing but the collection of data. The network layer is very important and it is responsible for the transmission of packets from the source to destination. Here the data’s are framed and a proper IP address is given to the frame or packets. According to the address found in the packets or frames the data will be transferred appropriately to the destination.
Hi friends! Data link layer is the second layer as well as the most important layer that deals with the data transmission. The data’s are partitioned into frames and they are sent from one node to the next. Physical layer acts as a link to transmit the data from it. If the data link layer fails all other layers will fail and the process will be stopped there.
Network models hold a very important place in the field of networking. It is must to know that there are seven layers in the network. Physical layer is the first layer as well as the lowest layer of the OSI model. This is the primary layer which is very important in the communication channel. It deals with electrical, mechanical terms, procedures, standards, functions and even more.
Standards provide guidelines or some set of procedure that are to be followed by others. Concerning standard compatibility of the device is very important. A standard helps in maintaining everything inside the network. Different kinds of categories are available for the Standards of the network. All the standards should be properly maintained to get a very good result.
