“The importance of network is not greed but generosity”. This phrase simplifies the importance of the network layer in the technology area. In this world of computer science, communication seems very easy from one network to another. Suppose, if you want to send messages but there’s a network issue, then because of this you both will suffer. So to avoid such communication gaps, here comes the network layer which makes it easier. This is a very crucial topic to learn from IT assignment writing help and you can also relate it with real life. The network layer is the part of the internet communications process where the connection occurs by sending data. The network layer takes place within the inter-network connections. Well, students face many difficulties while remembering all the seven layers of the network. So, to avoid this problem read this article until the end & get the easiest way to learn network layers.
Let’s take a look.
- Physical Layer
The physical layer transfers the data in binary form. Basically, this involves media, and the communication takes place into bits form. Bits are the smallest unit of information that is shared over wires, radio waves, and cables.
- Data Link Layer
The data link layer handles communications between devices on the same network in the form of frames. This mostly uses an Ethernet protocol to share the data. This layer also detects the error and also simultaneously controls the data.
- Network Layer
This layer handles the routing and sending of data between different networks in packet form. The most important protocol for this layer is IP and ICMP. The network layer performs various functions such as sorting, filtering, and distribution.
- Transport Layer
The transport layer provides the means for transmitting data between the connected parties and the quality service as well. The data is usually moved in segment form with the majorly used protocol such as TCP & UDP. This layer is basically responsible for controlling data flow. If in case any error occurs, then it reconnects the data and re-transmits for sequencing.
- Session Layer
The session layer controls the connection between computers usually by the TCP protocol. The major functioning of the layer is the establishment, management, and termination. This layer transfers data from the end of the user. The session layer provides a virtual agreement between two end-communication.
- Presentation Layer
The major protocols for this layer are JPEG, GIF, PNG, MP3, etc. This layer facilitates the presentation of data to the upper layer. In this layer, data is transmitted into the form of an application. The layer also provides an encoding scheme and encryption formation.
- Application Layer
This is the last layer of the network. It provides an interface between users and machines. The main protocol that is used to exchange the data is HTTP. In this layer, data is generated by the user and sent to software applications.
These are the seven layers of network that is mostly asked from the students. The IT assignment writing help professionals defines the layers in a simple and easy strategy to recall while writing. By applying this strategy in your document, you will have a positive impression on your professor.
SUMMARY: This article provides 7 network layers to the student to do the assignment writing in a perfect way. A student will get an idea of how to learn tricky network layers perfectly to get an A+ grade.
