Q1. How many type of network layer

Ans.

There are 7 types of network layers.

  • The 7 types are: physical, data link, network, transport, session, presentation, and application.

  • Each layer has a specific function in the communication process.

  • Examples of protocols at each layer include Ethernet at the data link layer and HTTP at the application layer.

Q2. What is bgp protocol.

Ans.

BGP (Border Gateway Protocol) is a routing protocol used to exchange routing information between different networks on the internet.

  • BGP is used to connect different autonomous systems (AS) on the internet.

  • It is a path-vector protocol that uses TCP as its transport protocol.

  • BGP is used by internet service providers (ISPs) to route traffic between different networks.

  • It allows for policy-based routing, where network administrators can control how traffic flows through their netw...read more

Q3. What is data link layer.

Ans.

Data link layer is the second layer of the OSI model responsible for error-free transfer of data between adjacent nodes.

  • It provides framing, error control, flow control, and access control.

  • Examples include Ethernet, Wi-Fi, and Bluetooth.

  • It ensures that data is transmitted reliably and efficiently over the physical layer.

  • It also handles addressing and routing of data packets.

Q4. What is ospf.

Ans.

OSPF (Open Shortest Path First) is a routing protocol used to exchange routing information within a single autonomous system.

  • OSPF is a link-state protocol that uses Dijkstra's algorithm to calculate the shortest path between two points.

  • It is designed to work with large networks and supports VLSM (Variable Length Subnet Masking).

  • OSPF uses a hierarchical structure with areas to reduce the amount of routing information exchanged.

  • It is commonly used in enterprise networks and is ...read more

Q5. What is router.

Ans.

A router is a networking device that forwards data packets between computer networks.

  • Routers operate at the network layer of the OSI model.

  • They use routing tables to determine the best path for data to travel.

  • Routers can connect different types of networks, such as LANs and WANs.

  • Examples of routers include Cisco, Juniper, and TP-Link.

  • Routers can provide security features such as firewalls and VPNs.

Q6. What is switch.

Ans.

A switch is a networking device that connects devices together on a local area network (LAN).

  • Switches operate at the data link layer of the OSI model.

  • They use MAC addresses to forward data to the correct destination device.

  • Switches can improve network performance by reducing network congestion.

  • Examples of switches include Cisco Catalyst switches and Netgear ProSAFE switches.

Q7. What is osi model

Ans.

The OSI model is a conceptual framework that standardizes the functions of a telecommunication or computing system into seven layers.

  • The OSI model stands for Open Systems Interconnection model.

  • It helps in understanding how different networking protocols work together.

  • Each layer in the OSI model has a specific function and communicates with the adjacent layers.

  • Examples of layers include physical layer, data link layer, network layer, transport layer, session layer, presentatio...read more
