Block-Level Elements

A. Behavior: Start on a new line and automatically stretch to fill the full width of their container.

B. Layout: Can have width, height, margin, and padding set on all four sides.

Inline Elements

A. Behavior: Do not start on a new line; they sit side-by-side within the flow of text.

c Purpose: Used to format or apply styles to specific words or small inline portions of text.

Web and hosting service, refers to the services and server information that make website accessible to user over the internet.

Web Hosting Essentials
.Core Function: Web hosts rent out server space, computing power, etc.

Common Hosting Types:
.Shared Hosting: Multiple websites share resources on a single server
.VPS (Virtual Private Server): Virtualized dedicated space offering more isolated control and performance.
.Cloud Hosting: Websites run on a network of connected servers for maximum uptime and scalability. etc.

Internet Networking

.Definition: Internet networking is the global system that connects computers, smartphones, servers, and other devices so they can exchange information.

.How it works:

.Packets: Data is broken into small units called packets. Each packet carries part of the message plus addressing information.

.Transmission: Packets travel through physical media (like fiber-optic cables, copper wires) or wireless signals (Wi-Fi, cellular networks).

.Routers & Switches: Special devices guide packets along the best path to their destination.

.Protocols: Rules such as TCP/IP ensure packets are sent, received, and reassembled correctly, even if they take different routes.

.Key Components:

.IP Address: A unique identifier for each device on the network.

.DNS (Domain Name System): Translates human-friendly names (like google.com) into IP addresses.

.Servers & Clients: Servers provide resources (websites, files), while clients (your computer/phone) request and use them.

.Why it matters:

Enables communication (email, messaging, video calls).

Provides access to information (websites, cloud storage).

Powers commerce, entertainment, and social interaction worldwide.
