BGP (Border Gateway Protocol) is a routing protocol used to exchange routing information between different autonomous systems (AS).

• BGP is used to exchange routing information and prefixes between different AS numbers.

• BGP helps in determining the best path for data to travel between networks.

• BGP operates on TCP port 179.

• BGP uses attributes like AS path, next hop, and local preference to make routing decisions.

• Example: B...read more

Conductor, capacitor, and resistor are basic components used in electronic circuits.

• Conductor: Allows the flow of electric current. Example: Copper wire.

• Capacitor: Stores and releases electrical energy. Example: Ceramic capacitor.

• Resistor: Limits the flow of electric current. Example: Carbon film resistor.

A switch is a networking device that connects devices within a local area network (LAN) and forwards data packets between them.

• Switch operates at the data link layer of the OSI model

• It uses MAC addresses to forward data to the correct destination

• Switches increase network performance by reducing collisions and segmenting traffic

• Examples of switches include Cisco Catalyst series, Juniper EX series, etc.

A router is a networking device that forwards data packets between computer networks. It operates at the network layer of the OSI model.

• Routes data packets between different networks

• Uses IP addresses to determine where to send data packets

• Helps in creating and maintaining a network topology

• Can be configured with access control lists to control traffic flow
