The OSI Layers refer to the seven layers of the Open Systems Interconnection model that define the functions of a network protocol stack.
Layer 1 - Physical Layer: Deals with physical connections and transmission of raw data over a physical medium (e.g. cables, wires)
Layer 2 - Data Link Layer: Responsible for node-to-node communication, error detection, and flow control (e.g. Ethernet switches)
Layer 3 - Network Layer: M...
When you search for something on the internet, your query is sent to a search engine which then retrieves relevant information from its index of websites.
User enters a search query into a search engine.
Search engine uses algorithms to find relevant websites from its index.
Search results are displayed to the user based on relevance and ranking.
User can click on search results to access the desired information.

Border Gateway Protocol
BGP stands for Border Gateway Protocol
It is a standardized exterior gateway protocol used to exchange routing information between different autonomous systems on the internet
BGP helps in determining the best path for data to travel between networks
It is commonly used by Internet Service Providers (ISPs) and large organizations to connect to multiple networks
BGP operates on TCP port 179
Routers are networking devices that forward 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 packets
Routers can connect different types of networks, such as LANs and WANs
