The OSI model, or Open Systems Interconnection model, is a conceptual framework used to understand how different networking protocols and technologies fit together to allow for communication between devices on a network. It divides networking into seven distinct layers, each with its own set of protocols and functions.
One question that may come up when discussing the OSI model is why it is divided into seven layers. The reason for this is that each layer serves a specific purpose and handles a specific type of information. By breaking down networking into these distinct layers, it becomes easier to understand how different technologies fit together and how to troubleshoot problems that may arise.
Another question that may come up is how the OSI model relates to other networking models, such as the TCP/IP model. The OSI model and the TCP/IP model are both frameworks for understanding how networking works, but they approach the topic from slightly different angles. The OSI model is more focused on the overall structure of a network and how different technologies fit together, while the TCP/IP model is more focused on the specific protocols and technologies used to transmit data over a network.
A third question that may come up when discussing the OSI model is how it is used in practice. While the OSI model is primarily a theoretical concept, it is still widely used as a reference when designing and implementing networking systems. It provides a common language that can be used by networking professionals to understand and communicate about complex networking concepts and technologies.
Overall, the OSI model is an important tool for understanding how networking works and how different technologies fit together. It provides a framework for thinking about networking that can be helpful when designing, implementing, and troubleshooting networks.

Error Controls the process of detecting and correcting both the bit and packet-level error. The fifth layer, the session layer, is responsible for managing the session between the two systems. The OSI reference model is used as a guide for teaching and understanding the way networks operate. Answer: A D Explanation The transport layer segments data into smaller pieces for transport. What is the way to establish a TCP connection? It is used to map multiple private IP addresses to a single public IP address. Layer 3 Network IPV5, IPV6, ICMP, IPSEC, ARP, MPLS.
What is an IP address? In bi-directional communication, the HTTPS protocol encrypts the communication so the tampering of the info gets avoided. When data is transferred from the lower layer to the higher layer, each layer removes the information added by the other layers. What is the role of the LLC sublayer in thedata link layer?

IP address comes under the network layer of the OSI model.
Why is subnetting done? SMTP is short for Simple Mail Transfer Protocol. Ans: From top to bottom, OSI layers are, Application, Presentation, Session, Transport, Network, Data Link, and Physical Layer. FTP port number 20 Data ; 21 for Control Which layer provides the logical addressing that routers will use for path determination? To troubleshoot network problems by verifying functionality of each layer. Network problems may be a loose physical connection, configuration issues, etc. Multicast is the term used to describe communication where a piece of information is sent from a single source and transmitted to many devices but not all devices.
Que: What are the responsibilities of the Transport Layer? VRF is a technology that allows multiple virtual routers to exist on a single physical router. What are the responsibilities of the Network Layer? A VLAN is a virtual LAN. It also checks the integrity at arrival. Network Layer Switches work at which OSI layer? Que: Routers work at which OSI layer? Packets are created when the network layer encapsulates a frame with source and destination host addresses and protocol-related control information. Which layer segments and resembles data into a data stream? Flow control is agreeing on the minimum amount of data that a receiver can handle at a time.
In IPV4 There is a Field called Protocol to identify the Next Level Protocol. OSI model is an important concept if you want to understand networking. These are a couple of protocol layers that were created to make data exchange possible on various kinds of computer networks, also referred to as heterogeneous networks. UDP is faster as the recovery of error is not attempted. MAC Address IP Address MAC address is Media Access Control Address.

Which Layer is responsible for Reliable connection? Routing is the process of finding a path on which data can pass from source to destination. What are the 7 layers of the OSI model? Devices in the same VLAN can communicate with each other as if they were on the same physical network. Ans: As the name suggests, flow control controls the rate of information transmitted to ensure the receiver's efficient delivery of data. It is made up of 7 layers, with each layer defining a particular facet of how network devices connect and speak with one another. Each layer adds its header to the original packet. You can redeem the IP address of any device RARP protocol. Media Access Control provides physical addressing while Logical Link Control provides error detection, using Ethernet trailer field frame check sequence FCS.
I am going to watch out for brussels. It translates messages from the Network layer into bits for the Physical layer to transmit. A lot of people will probably be benefited out of your writing. OSI Model MCQ Questions And Answers OSI Model MCQs : This section focuses on "OSI Model" in Computer Networks.

What are the differences between the MAC sublayer and LLC sublayer? A Protocol data unit PDU is an OSI term given to the chunks of information either added encapsulation or removed decapsulation by an OSI layer. ARP is the Address Resolution Protocol, and it is used to map IP addresses to physical addresses.
The data link layer is mainly divided into two sublayers. Ans: Data Link Layer Que: Which Layer manages device addressing, tracks the location of devices on the network, and determine the best way to move data? Broadcast is the term used to describe communication where a piece of information is sent to all nodes on the network. It is 4 bytes field. TCP is reliable because it guarantees the delivery of knowledge to the destination router.
