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

• The OSI model stands for Open Systems Interconnection model.

• It was developed by the International Organization for Standardization (ISO) in 1984.

• The model divides the communication process into seven layers, each with its own specific functions.

• The layers are: Physical, Data Link, Network, Transport, Sess...read more

An IP address is a unique numerical label assigned to each device connected to a computer network.

• IP address stands for Internet Protocol address.

• It is used to identify and locate devices on a network.

• IP addresses can be either IPv4 (32-bit) or IPv6 (128-bit) format.

• IPv4 addresses are written in the form of four sets of numbers separated by periods (e.g., 192.168.0.1).

• IPv6 addresses are written in the form of eight gro...read more

TCP is a reliable, connection-oriented protocol while UDP is a fast, unreliable, connectionless protocol.

• TCP provides guaranteed delivery of data packets while UDP does not.

• TCP ensures data integrity through error checking and retransmission of lost packets.

• UDP is faster and more efficient for real-time applications like video streaming or online gaming.

• TCP is used for applications that require reliable and ordered del...read more

Switch is used at the data link layer of the OSI model.

• Switches operate at Layer 2 of the OSI model.

• They use MAC addresses to forward data within a local area network (LAN).

• Switches improve network performance by reducing collisions and providing dedicated bandwidth.

• Examples of switches include Ethernet switches and VLAN switches.

The 2nd layer in the network model is the Data Link Layer.

• The Data Link Layer is responsible for the physical addressing of devices on the network.

• It ensures reliable transmission of data over the physical layer.

• Examples of protocols at this layer include Ethernet, Wi-Fi, and PPP.

BGP (Border Gateway Protocol) is an exterior gateway protocol used in internet routing. It is used to exchange routing information between different autonomous systems.

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

• It is a path-vector protocol that determines the best path for data packets to travel between AS.

• BGP has two main types: eBGP (External BGP) and iBGP (Internal BGP).

• eBGP is used to ...read more

Fireball is not used in hardware.

• Fireball is not a term commonly used in the context of hardware.

• There is no specific hardware component or technology called Fireball.

• It is possible that the interviewer may have made a mistake or referred to a different term.

A subnet is a logical subdivision of an IP network. It allows for efficient use of IP addresses and helps in network management.

• Subnets divide a larger network into smaller, more manageable networks.

• They are created by borrowing bits from the host portion of an IP address.

• Subnetting helps in reducing network congestion and improving security.

• Types of subnets include Classful Subnetting, Classless Inter-Domain Routing (...read more
