World Wide Web
The network of pages of images, texts and sounds on the Internet which can be viewed using browser software.
World Wide Web
These run on sophisticated hardware.
Servers
To dominant implementations.
Clients/browsers
Many interesting implementations.
Caches
The global infrastructure which facilitates data transfer.
Internet
HTTP
Hyper Text Transfer Protocol
HTML
Hyper Text Markup Language
XML
Extensible Markup Language
URIs
Uniform Resource Identifiers
An infrastructure of information combined and the network software used to access it.
The Web
A document that contains or references various kinds of data.
Web page
A software tool that retrieves and displays web pages.
Web browser
A computer set up to respond to requests for web pages.
Web server
It is a collection of related web pages including: Entertainment, advocacy, personal, and etc.
Website
It provides a set of rules and standards that govern how information is transmitted on the WWW.
HyperText Transfer Protocol (HTTP)
It is the Web’s application-layer protocol for transferring various forms of data between server and client.
HTTP
A software that hosts websites via Internet.
Web servers
How do web browsers communicate with web browser?
HyperText Transfer Protocol
In this server, you get a centrally-located pool of disk space to store and share different documents in the form of emails for network users. All data is stored in a single location and so, administrators need to backup files only from one computer.
Mail Server
It acts as a set of components which can be accessed by the software developer via an API defined by the platform itself.
Application Server
These components are usually performed in the environment similar to its web server(s) for the web applications with the main job of supporting the construction of dynamic pages.
Application Server
It uses separate control and data connections between the client and the server. This server also authorizes itself in the form of a username and password.
File Transfer Protocol (FTP) Protocol
A computer program that offers database services to other computer programs or computers with the use of client-server functionality.
Database Service
This type of server is accessible either via a “front end” that runs on the user’s computer where the request is made or the “back end” where it is served such as data analysis and storage.
Database Server
A computer server that hosts a network service for offering responses to queries which maps either an addressing component or numeric identification. This is done by the server to give response to a network service protocol request.
Domain Name System (DNS) Server
It is a type of software that allows you to find and view websites on the Internet.
Web browser
Its primary function is to render HTML.
Web browser
It is the code used to design or markup webpages which may include text, links, and references to images and other items, such as cascading style sheets and JavaScript functions.
HyperText Markup Language (HTML)
It is the fundamental network identification for any resource connected to the web, utilizing a web address.
Uniform Resource Locator
A server that is specifically used for matching website hostnames to their corresponding IP address.
DNS Server
It contains a database of public IP addresses and their corresponding domain names.
DNS Server
It is the unique name that identifies an Internet site and email address.
Domain Name
It is a program that searchers for and identifies items in a database that correspond to keywords or characters specified by the user, used specifically for finding particular sites on the World Wide Web.
Search Engine
The code language used to create Hypertext documents for use on the World Wide Web.
HTML
It is the standard used to secure the exchanging of files over the Internet.
File Transfer Protocol (FTP)
The transferring of files from the client to the server.
Uploading
The transferring of files from a server to a client.
Downloading
It is a small text file that a web server stores on your local computer’s hard disk, containing information about your visit to the site.
Cookie
It is the collection and analysis of data regarding website usage, typically used by website owners to track the number and behavior of users visiting their sites.
Web analytics
Any resource that is provided over the Internet.
Cloud service
It is a network security device that monitors incoming and outgoing network traffic and decides whether to allow or block specific traffic based on a defined set of Security rules.
