Study Notes

Internet Overview

The internet is a global network of interconnected computers, established through collaboration and governed by standard protocols.
No single entity owns the internet; it operates on a framework of shared rules.

Ways to Transfer Information

Email Protocols: Utilize POP3, IMAP, and SMTP for sending and receiving messages.
File Transfer: FTP (File Transfer Protocol) facilitates the transfer of files between computers.
Secure Shell: SSH is employed for secure remote access to computers.
World Wide Web: Enables access to linked documents through hypertext, creating an expansive network of information.

Protocols

Protocols dictate standardized methods for data transfer across networks.

Web and Servers

The World Wide Web connects documents via hypertext links.
Web servers respond to requests for information, providing documents quickly.
HTTP servers are a common designation for web servers.

Popular Web Server Software

Apache: Open source software widely used for web servers.
Microsoft Internet Information Services (IIS): A proprietary web server software from Microsoft.

IP Address and Domain Name System (DNS)

Unique numeric IP addresses are assigned to every device on the internet.
DNS translates domain names into IP addresses, making it easier for users to access servers.
A single IP address can host multiple domain names, allowing shared resources.

Client and User Interaction

Clients refer to software, such as desktop and mobile browsers, that send requests to servers.
Browsers (also known as user agents) display retrieved documents to users.

HTTP Protocol

HTTP serves as a transfer method for various web resources, including images, videos, audio files, and scripts.
