ISP
The ISP (Internet Service Provider) is an organisation that provides access to the internet and this is directly connected with the clients by using copper wiring, wireless or by fiber-optic connections. Different organisations of the Internet Service Providers may be organised in many different forms, like;

• Commercial 
• Community-owned 
• Non-profit
• Privately-owned 

Web Hosting Services

This basically allows anyone (people or organisations) to make and design their own website and this is accessible by the World Wide Web. Also all web host companies that provide space on a server that is owned or leased for use by the clients that they have bought or leased for. As well as providing internet connections. This is what they call a "Data Centre", web hosts also provide data spaces and connectivity for other services that are located in the Data Centre.

Domain Structure
A domain structure is a cluster of computers which maintains it's own security and accounts management locally, i.e.-on the primary domain controller. All logins for local accounts are done within the domain, and it has its own file and application servers for locally logged on users. A database domain is a support for goods and services domain along with a client domain and even a client domain for data programmers/software engineers.

Domain Name Registrars
A domain name registrar is an organization or commercial being that manages the reservation of internet domain names. A domain name registrar must be authourised by a top-level domain registry. The management is done in accordance with the guidelines of the designated domain name registries and to offer such services to the public.

Worldwide Web

The World Wide Web is a system of interlinked hypertext documents accessed through the Internet. With a web browser, one can view web pages that may contain text, images, videos, and other multimedia, and navigate between them through hyperlinks.

Mail Clients

Mail Clients is a computer program that used for accessing the users Email and allows them to manage their emails. Clients can refer to any system that is capable of handling the users email and regardless of it being a mail user agent, a relaying server or a person typing manually on a terminal. Also a web application that provides message management, composition and reception functions is sometimes considered an email client but is more commonly known as webmail. popular email clients include:  Microsoft Outlook, IBM Lotus Notes, Pegasus Mail, Mozilla's Thunderbird, KMail in the Kontact suite, Evolution and Apple Inc.'s Mail.

Components

Hardware

Web browsers are more commonly known as Browsers, and it is a software application for retrieving, presenting and traversing information resources on the Worldwide Web. An information source will be identified as an Uniform Resource Identifier (URI) and this maybe a webpage, image, video or any other piece of informational content. Hyperlinks are also presented into resources and enable the users to easily navigate their selected browsers to the related resource. Also a web browser can also be defined as an software application or a program that is designed to enable easy access for the users to get, send and view information or any other resources that come form the internet.

Hub

A Hub is a device that allows multiple Ethernet devices to be connected together and allowing them to create a single network segment, also it has many input/output ports then after then a signal is introduced at  the input port and any port that appears on the output except the original incoming. Also the device works as a physical layer of the OSI model, and it forms a multiple repeater and the repeater hubs can also participate in collection detection, forwarding a jamming signal to all ports if it detects a collisions.

Web Server 

Web Servers can also be referred as hardware on a computer or a software application on the computer, this helps to deliver web content to the Client and it can be accessed through the internet and the most common used of the web servers are called 'websites' but other web servers that offer that same as website and they are applications such as 'gaming', 'data storage' or running enterprise applications. The primary function of a web server is to deliver web pages on the request to clients using the HTTP. This means that the delivery of the HTML documents and any additional content that may be included by a document, such as images, style sheets and scripts.

Web 2.0

Web 2.0 was created in 1999 and it was used to describe websites that uses technology that was beyond the static pages of the previous websites. Although it suggests that the updated version of the Worldwide Web doesn't refer to an update to any of the technical specification but they will have changed by the software developers and the end-users that use the web. A Web 2.0 site allows users to interact and collaborate with others in social networking sites, such as Facebook and Twitter, their dialogue creators of user-generated content in a virtual community.

Blogs

Blogs are discussions or informational online sites that get published on the internet and that these documents consists of entries (posts). Also these are posted in the typically displayed way of being in reverse chronological order (when the most recent will appear first). Up-till 2009 these posts were posted individually or on occasion in small groups of 3/4 and often covered by the same subject and even more recently 'multi-author blogs' 'MAB's' have been developed and with posts that were written in large numbers of authors and that it professionally edited.  MAB's from newspapers, other media outlets, universities, think tanks, institutions and similar accounts of ever increasing number of blogs being released onto the internet. The rise of Social Networking sites like Facebook and Twitter and 'Mircoblogging' systems they help to migrate the MAB's and single bloggers into societal mainstreams. 

Online Applications 

Online Applications (Web Applications) is an application that is accessed by the user that is on a network such as the 'internet' or the 'intranet'. The term Web Application may also mean a computer software application that is coded in a web-browser-supported program language (like JavaScript and combined with rendering-browsers in the make-up language like HTML). A majority are interactive, allowing visitors to leave comments and even message each other via GUI widgets on the blogs, and it is this interactivity that distinguishes them from other static websites, also blogging can be seen as a form of social networking. Many blogs provide commentary on a particular subject, others function like personal online diaries, others function more as online brand advertising of a particular individual or company.

Cloud Computing

Cloud Computing is use of computer resources in both hardware and software that is delivered as services over networkds (like the internet). Also the name comes from theuse of the Cloud-Shaped symbol as an abstraction for a complex infrastructure that contains it in the system diagram and Cloud Computing trusts any remote services with the users data, software and computation. End users access cloud-based applications through a web browser or a light-weight desktop or mobile app while the business software and user's data are stored on servers at a remote location.

Protocols

Transport and Addressing
Internet Protocol (IP) Addresses are the universally-used main form of addressing on a TCP/IP network. These Network-layer Addresses are uniquely eidetic from each of the networks interfaces, these sever as the mechanics by which the data is routed to the correct network on the internet work and there will be the correct device on that network. some people do not realise that there is an additional level of addressing that will occur at the point of the transport layer which is called TCP/IP. Above is the IP address. both of the TCP/IP transport protocols TCPs and the UDP use concepts of ports and sockets for the virtual software addressing and that will enable the different functions of many different applications simultaneously on an IP device to work properly.

The image below shows various layers of the TCP/IP suite of protocols. At the top will be the application layer that consists of the application. Next will come the Transport layer UDP and the TCP, after will come the network layer that will contain the network (hardware)  interface. Finally the hardware layer and that contains all of the Physical Network. When the Application needs to send any type of data to another application which is on another host then the applications will send the information down to the transport level protocols to prepare the information for transmission.
