Study Notes

Web Servers and HTTP

Web servers respond to HTTP requests from web browsers, facilitating web page retrieval.

TCP/IP: Transmission Control Protocol/Internet Protocol

TCP/IP is the official communication protocol of the Internet, ensuring reliable communication.
TCP ensures data integrity by splitting files/messages into packets.
IP routes packets to their destination addresses and forwards them via routers.

IP Addresses

Each Internet-connected device has a unique numeric IP address composed of four octets (e.g., 173.194.116.72 for Google).
An IP address can correspond to a domain name for easier access.

Domain Name System (DNS)

DNS locates organizations on the Internet by associating domain names with IP addresses.
It divides the Internet into logical groups, simplifying navigation.

Uniform Resource Identifier (URI) and URL

URI identifies resources on the Internet.
URL is a type of URI specifying the network location of resources like web pages and files.

Top-Level Domain (TLD)

TLD identifies the right-most part of a domain name, with examples including .com, .org, .edu, and more.

Country Code TLDs

Two-character codes represent the geographical location of websites (e.g., .uk for the United Kingdom).
Domain names with country codes can often be registered regardless of the registrant's location.

Types of Websites

Dynamic Websites generate pages in real-time using server-side scripting languages (e.g., PHP, ASP.NET).

Internet Protocols

Protocols define rules for communication between clients and servers, with multiple protocols required for Internet functionality.

File Transfer Protocol (FTP)

FTP facilitates file exchange between computers, commonly used by developers to upload web files.

Email Protocols

Sending emails uses SMTP (Simple Mail Transfer Protocol).
Receiving emails is handled by POP (Post Office Protocol) and IMAP (Internet Mail Access Protocol).

Hypertext Transfer Protocol (HTTP)

HTTP governs the exchange of files (text, images, video) on the Web, with web browsers sending requests for files.

The Internet

The Internet is a global network of interconnected computer networks.

Growth of the Internet in the 1990s

Key growth factors include the removal of the ban on commercial activity and the development of the World Wide Web by Tim Berners-Lee.
The launch of the Mosaic browser and the affordability of personal computers also contributed to growth.

The World Wide Web

A graphical user interface for accessing information stored on web servers connected to the Internet.

Network Overview

A network consists of multiple computers connected for communication and resource sharing.

Types of Networks

LAN (Local Area Network) – confined to a single building/group of buildings.
WAN (Wide Area Network) – connects computers over large geographic distances, often using public networks.

Internet Infrastructure

The Internet Backbone consists of high-capacity communication links that handle data from smaller interconnected links.

Client/Server Model

In the client/server relationship, the client requests services (like files) from the server, establishing a network interaction framework.
