Part 1 - A brief history of the internet (learning outcomes)

Question 1

understand the history of the Web and the impact standards and protocols have on the deployment of web-distributed applications

Answer 1

The history of the web begins with the internet that was born out of resaerch by the arpanet project in 1969. the aim was to enable computers to reliably communicate with each other out of this was born the TCP/IP. In 1991 the world wide web was released and meant that computers could now reliably share documents with each other using HTTP and reliably view the document which could contain text, video and scripts HTML. The impact of these standards being introduced is that you can reliably connect to and exchange documents without the worry of some kind of failure

Question 2

have some understanding and be able to explain the basic modes of operation of the client–server model of the Web and the associated protocols, including HTTP

Answer 2

the client server model is one where a client typically a browser can request information from a server typically a computer with the required software installed. This model needs a way that both computers understand and can speak to each other this is where protocols such as HTTP come in allowing client and server to in a sense talk with each other

Question 3

discuss the role of standards for developing web applications

Answer 3

Adhering to standards when developing web applications means that your web application can and will be reliably understood by any client that would want to use it. Implementing your own way of doing things takes the risk that your web application cannot be connected to or even understood by a client
