The OSI model helps to understand how different network protocols work together and how to troubleshoot network problems.👆

👉Data link layer: Transmits and receives frames over a physical medium and performs error detection and correction. 👉Physical layer: Defines the electrical, mechanical and functional characteristics of the physical medium.🧵

👉Session layer: Establishes, maintains and terminates sessions between applications or devices. 👉Transport layer: Provides reliable or unreliable data transfer and error control. 👉Network layer: Routes packets across networks and handles addressing and congestion control.🧵

👉 Application layer: Provides services and interfaces for applications to access network resources. 👉 Presentation layer: Translates data formats and encodes or decodes data for encryption or compression.🧵#OSINetworking #OSIStack #OSIQuiz #OSITips #OSIFun

The OSI model is a conceptual framework that describes how different network protocols interact and communicate. The model consists of seven layers, each with a specific function and responsibility. The layers are:🧵#OSIModel #OSILayers #OSIReference #OSIProtocol #OSISecurity

The OSI model divides the communication process into seven layers, each with a specific function and protocol. The network model for databases allows objects and relationships to be represented as nodes and arcs in a graph, which can be more flexible than a hierarchy or lattice.

A networking model is a way of describing how different parts of a communication system interact with each other. There are different types of networking models, such as the **OSI model** and the **network model** for databases. #OSIModel #TCPModel #UDPModel #InternetModel #Cisco

UDP is suitable for applications that can tolerate some data loss, such as streaming media or online games. TCP is suitable for applications that require reliable and accurate data transfer, such as web browsing or email. #TCP #UDP #network #Cisco #CCNA #networking #Internet

TCP ensures that the data is delivered in the correct order and without errors, by using acknowledgments, retransmissions, and checksums. UDP does not provide any guarantee of delivery, order, or error correction, but it is faster and more efficient than TCP. #data #switching

TCP and UDP are two protocols that are used to send data over the internet. TCP stands for Transmission Control Protocol, and UDP stands for User Datagram Protocol. The main difference between them is that TCP is reliable and UDP is not. #certification

The condition after #if has one or more of the following operators:👉<: less — the condition is true if left side is less than right side👉>: greater — the condition is true if left side is greater than right side👉<=: less or equal👉>=: greater or equal👉==: equal👉!=: not equal

In most of the other languages, the curly braces { and } are used to form blocks. The creators of #Python decided to replace {...}-like blocks with indentation. Indentation makes your code far more readable than keeping an eye on all the curly braces. #100DaysOfCode #CodeNewbies

The conditional statement in #Python has the following syntax: if condition: true-block several instructions that are executed if the condition evaluates to True else: false-block several instructions that are executed if the condition evaluates to False
