1.1 History of website
WWW stands for World Wide Web and was created in 1989 by Tim

Berners Lee, a British physicist. Since then, it has been constantly
evolving and improving.


How to web work

Step 1: URL gets resolved
Step 2: Request is sent

Step 3: Response is parsed
Step 4: Website is displayed




1.2 Identity the purpose and types of DNS
Definition: DNS (Domain Name System) is a system that translates domain names
into IP addresses, allowing devices to connect to the internet using human-readable

domain names instead of numerical IP addresses.
Purpose: DNS translates human-readable domain names like www.example.com
into numerical IP addresses for computers to interact over the internet, making
it a critical component of internet architecture.


Types of DNS
There are several types of DNS servers

or.org in the URL.


1.3 How domain names are organized

DNS is hierarchical, with multiple organizations controlling domains at
various query stages.
The root zone database is managed by IANA, an ICANN affiliate, with 12
companies administering hundreds of root servers.


1.4 How domain names are managed
DNS manages its distributed database using a hierarchical structure
known as the domain name space. This structure is an inverted tree,
with the root domain at the top. The root domain is denoted by a (.).

1.5 Communication protocol

Definition: Communication protocols are sets of rules and standards that govern
the exchange of data between devices on a network. They define the format,
timing, sequencing, and error control mechanisms required for successful

communication.


Purpose

Cover authentication,
error detection, and
signaling.

Message consistency
should be used to
communicate.

Explain syntactic
semantics and analog
synchronization.


Some types communication protocols

FTP

TCP protocols

IP address


Hypertext Transfer Protocols
HTTP (Hypertext Transfer Protocol) is a communication
protocol that enables the transfer of data between a client
(usually a web browser) and a server over the internet.

It defines how messages are formatted and
transmitted, as well as what actions web servers
and browsers should take in response to various
commands.


1.6 Web server hardware
Servers are tangible pieces of hardware that are in charge of storing
data. There are several kinds of servers accessible. Regardless of the

options, there is a huge array of server hardware accessible.


Tower servers are designed to be placed on a desk or on the

floor and are typically used by small businesses or for
applications that require only a few servers.

Blade servers are similar to rack-mounted servers, but
they offer greater scalability and flexibility by fitting into

a blade enclosure that can hold multiple blade servers.

1.7 Operating system

An operating system (OS) is a software that manages a computer's
hardware and provides common services for computer programs.
Purpose: Its primary purpose is to act as an interface between the
computer's hardware and its users, allowing them to interact with
the system and run applications.
Type of Server OS:
Windows server (2000, 2003 R3, 2008…)
Unix (Red Hat)
Mac OS X Server


1.8 Web server software
The server is the software (not the computer itself) that:
- Allows the computer to communicate with other computers

-Waits for a request for information, then retrieve and send that
information back as quickly as possible
This software is installed In the actual computer, which is installed
server operating system and called host.
