Study Notes

Internet and Hosts

A host is any computer or device connected to the Internet, such as computers, printers, and smartphones.
The Internet is defined as a network of interconnected networks.
Each host on the Internet has a unique IP address, analogous to a physical mailing address.

Basic Architecture

Hosts connect to the Internet via a router, which is a specialized computer that routes data between networks.
Routers act as central hubs within a Local Area Network (LAN) and facilitate dynamic routing, meaning routes are not predetermined.

IP Addressing

Hosts are reachable through their unique IP addresses or domain names (e.g., njctl.org corresponds to IP address 35.162.99.125).
IP addressing functions similarly to the postal service, directing data (or "mail") to the correct destination based on the address.

Client/Server Model

The Client/Server Model organizes interactions in the Internet, separating service providers (servers) from service requesters (clients).
For example, Gmail utilizes Google's servers to manage email, with clients sending requests to access or send messages.

Client vs. Host

A client can be either hardware or software that requests services from a server, distinguishing it from a host.
A host refers to the physical device or computer, which can operate as either a server or a client.
Servers are located on hosts and provide necessary services to clients, whereas clients do not share their resources.
