The development of web
Make an effective connections
Introduction of FTTH connection
Technology is becoming popular
It does not matter the career you belong to or the qualifications you hold, if you cannot remember past event/history, you don't deserve those qualifications, you don't deserve to be respected, infact, it is a taboo for mankind to pass through this world without allowing the world pass through him.
In as much as web histories were not fully reserved, artifacts traced to the last three decades has been preserved, thanks to web historians. Keeping record of the past while running our race is a vital and tedious task. Due to peoples lack of consideration in important things like this, numerous site we know nothing about has been cleared from history without any trace. This will continue this way until we change our mindset and begin to see reasons why we should store up this events.
There have been observable improvement in the development of web. Though not as popular as technology, it passed through the same process of history.
Web 1.0 was able to perform operations just like web 2.0 but in a different way.
For instance, while web 2.0 have a comment section for users to share their thoughts, web 1.0 has visitorsbook were visitor's comments are published.
According to Cormode G. and Krishnamurthy B. " content creators were few in web 1.0 with the vast majority of users simply acting as consumers of content"
In 1999, Darcy Dinucci gave web 2.0 its name. When web 2.0 was launched, people did not see it as an upgrade to any specification, they viewed it as a new web page design with new features. Interaction on social media were unlimited.
Terry Flew in a news media, described the main differences between web 1.0 and web 2.0 ." Move from personal website to blogs and blog site aggregation, from publishing to participation, from web content as the outcome of large up-front investment to an ongoing and interactive process and from content management system to links based on tagging website content using keywords" Terry said.
Semantic web, also called web 3.0 was named by Berners-lee. It is a web where meaning can be derived by machines.
According to world wide web consortium(W3C), "The semantic web provides a common framework that allows data to be shared and reused across application, enterprise and community boundaries"
Due to changes and advancement, lot of differences has been sited over the years.
There are lot of things to point to when talking about the dissimilarities between web 1.0, web 2.0 and semantic web, the most vital ones are discussed below.
WEB 1.0- Users could store,distribute and review digital photograph. Web 1.0 inform users about lastest digital audio, songs and new improvement used in the music industry.
It has elements like static page, frames and tables to place features on page, filesystem to serve contents, HTML extensions like <blink> tag, online visitor'sbook, GIF buttons, HTML forms which operate with email, operating systems and text editor.
WEB 2.0- Unlike web 1.0, users could share their thoughts to the site content using the comment box. It has user account where users could have a base in the site to increase the site daily activities and participation. It has elements like dynamic HTML (a replacement to static page), a relational database management system, a web application written in a diverse programming language, software-as-a-service which allow automatic usage and mass participation where wide varities of users share thoughts and ideas. Example include facebook, linkedin, instagram and twitter. Site which involve social networking are good example of web 2.0.
• SEMANTIC WEB- It is also called web 3.0. It is an advancement of the previous web versions. It has features like uniform resource identifier(URLS) which uses HTTP protocol, resource description framework(RDF), web ontology language(OWL) and extensible markup language(XML). The links between them is described by HTML. More research is going on and soon, advance features will surface.
This involves large coverage of network resources which are interlinked via a network over a geographical location. It is a network that uses several WAN technologies.
WAN has a wide range of software features, ranging from customer premises equipment, data communication equipment, and data terminal equipment. Subscribers are usually the owners of customer premises equipment. Subscribers can also lease this device from service provider. There are cables which connect these devices to the service provider's main office. These cables are very important because they make the connection possible. The job of the data circuit- terminating equipment or data communication equipment, is to put data on local loop. Using this feature, communication link can be reached on the WAN cloud. Data terminal equipment make this possible by passing data to the device communication equipment.
The main hardware features include switches, modems and routers. For WAN to function effectively, these hardware features must be implemented.
Connection between a local area network and wide area network is made possible using routers, it uses IP address to make decisions.
It is an electronic device that takes care of tasks involving routing information between local area network and wide area network. Operations that involves sending unit of data by selecting the path, makes use of switch. Switch send data to the required destination using MAC addresses. While Routers operates at the third layer, switch operate at the second layer.
Communication between a computer and another computer using mobile phone lines is made possible using modem. For transmission to take place in this layer, signal must be transformed from digital to analogue. In this way, communication will take place more effectively. Modem operates at the first layer and may be called modulator in full.
The first and second layer is very important when it comes to the operation of wide area networks. While the first layer ensures effective communication between users, the second layer ensures secure data delivery to the right destination. Using internet service provider(ISP), the physical layer explain how to make an effective connections. The data-link layer explain ways in which data is packaged in a protocol header. Wide area network do not operate outside the physical and data-link layer. Most times, the data-link layer split data information before they are delivered. But when it gets to the required destination, it is then reassembled into the original information. Different information use similar network resources at a specific period of time.
ROLE OF INTERNET PROTOCOL ADDRESS
An internet protocol address( IP adress) is assigned to every automated device connected to the internet. While humans see it as decimal, computer uses it in binary form. It has a total of 32 bits address which is gotten from a position consisting of 8 bits. Octets are the four numbers that separate an ip address. It is divided into two parts consisting of host and network. Internet protocol address plays an important rule in WAN operations.
IMPORTANCE OF DIGITAL SUBSCRIBER LINE( DSL)
Wide area network need DSL for effective transmission. It speed up activities in the internet and remove any form of delay, making download fast and accurate. DSL connections are programmed online, so users don't need to wait for connection to be initiated. UK has over 20 million boardband connections and is expected to increase over the years.
