A gateway is a computer network node or router that serves as a
critical stopover point for the data on its way to or from other
networks. We can communicate and send data back and forth
thanks to gateways. Without gateways, the Internet would be
useless to us.
What do you understand about Gateway

A router is a computer networking layer system that manages and
forwards data packets. A gateway, on the other hand, is merely a
device or piece of hardware that operates as a “gate” across
networks. It might alternatively be described as a network node
that serves as an entry point for other nodes.
Determine the difference between a
gateway and a router

Cross-Site Scripting (XSS) is a web security vulnerability that allows
an attacker to manipulate how users interact with a susceptible
application. It will enable an attacker to get around the same
origin policy, which keeps websites separate from one another.
They are injection attacks in which malicious scripts are inserted
into otherwise trustworthy and simple websites.

The Open Systems Interconnection or OSI Model is a conceptual
framework for describing the functions of a networking system. In
order to facilitate interoperability between various devices and
applications, the OSI model describes computing functions into a
universal set of rules and standards. The connections among
computing systems are divided into seven abstraction layers in
the OSI reference model:
