Components of Web Architecture Involved in Website Communication

-

 

Lecture# 03 

to understand the role of web architecture in website communication we need to divide the components into three major categories.
  1. Hardware Components
  2. Software Components
  3. Network Components (Protocols)

Hardware Components:

To access the internet, you would need both hardware and software to be able to access it. The main piece of hardware you will need is a computer. 


1. Computer:

To access the internet, you would need both hardware and software to be able to access it. The main piece of hardware you will need is a computer. A computer will allow you to connect to another piece of hardware, that is the modem.
Computer

2. Modem

the modem, allowing users to connect to the internet. The modem is a box that can be connected to a computer by an Ethernet cable to provide internet and can have a built-in wireless router so that an internet connection is available around the house. Having a modem means that you would have paid for internet access from a broadband provider such as virgin or EE which would be your internet service provider. Without having an ISP you will not be able to access the internet, so customers are to buy and subscribe to ISPs to gain internet usage.



So after the modem is connected through the Ethernet cables to the computer, to set up the connection successfully, for example on a Windows computer, you would have to open up the “network and sharing center” and select which network you have, and enter the security key needed to gain access. Once done you should be connected to the internet.


Software Components:

After setting up the connection between the computer and the modem, for internet access to be available to you, the role of software begins. following are the software components

1. Browser

After setting up the connection between the computer and the modem, for internet access to be available to you, internet browsers are needed. There are many types of browsers users can use such as Internet Explorer, Google Chrome, or Mozilla Firefox.

2. World Wide Web 

Using web browsers gives users access to the World Wide Web. The World Wide Web consists of large amounts of web servers, which hosts websites, and billions of web pages containing text, graphics, sound files, videos, and animations.


 Network Components:

 1. Protocols

To use the internet, and communicate over the internet, a protocol is needed, for example, the most common protocol used is HTTP. Without the use of a protocol transmitting data between two systems can not be done, so protocols need to be used when accessing the internet.

2. Web Hosting Services

If you want to be able to access websites, for example, www.Twitter.com, for this website to be available to you, it must be hosted on a web server. This allows the connection between your computer system and the website. So for example, if you are trying to access Twitter and it isn’t hosted on a web server, you won’t be receiving any content from that website, making it impossible to use the website. So to access it, it must be hosted on a web server, and you must type in the domain name correctly. 

3. Domain

Each website is identified by the IP address of its web server. However, they are difficult to remember, are meaningless in terms of what the website contains, and are easy to mistype. Therefore a website on the Internet needs to purchase a domain name, which can be linked to the IP address. A domain name is the characters that appear between the prefix (eg www.) and the suffix (eg.com), for example 'Google'. A domain name should be easy for the user to remember, simple to type, and meaningful, reflecting the site's content. Usually, short names are best, but Mentone those at and westycnycar.com are
examples of whole phrases that have been used successfully. A useful thing to remember is that the existence of a site will only spread by word of mouth if it is easy to say, as well as type. Also consider purchasing similar domain names to the one you have chosen, in case a user mistypes it or forgets a section. For example, www.edexcel.com also owns www.edexcel.co.uk, www.edexel.com and www.edecel.com.

  Lecture# 01 Understand Web Architecture and Components in this lecture we will discuss the major components of website development. There are 4 components of website architecture. ISP An ISP (Internet Service Provider) is a company that provides its customers access to the internet. Without having an ISP, you will not be able to access the internet, Therefore customers are to buy and subscribe to ISPs to guarantee internet usage. Once choosing the right Internet service provider, you would have to determine the type of connection to the internet you wish to have, for example, some service providers offer up to 16GB worth of speed whilst on the internet, or even 10GB of using the internet monthly. One must decide on these factors before buying from the correct internet service provider. They usually provide internet access along with a package, for example, a username and password to an email account where the customer can manage their internet preferences and even a Modem, to set up

 Lecture# 02 Role of Web Architecture in Website Communication: A website must be uploaded onto a web server to allow it to be seen across the Internet. The process of uploading involves a protocol called FTP (file transfer protocol). FTPing can be done straight through a browser or using a program such as CuteFTP. It is not only the web pages that must be uploaded to the web server but all other associated files. This includes image, video, and sound files. This is because these files are not embedded into web pages, but linked to them, remaining as separate entities. A web server holds the live copy of the web page which can be seen by the public. There are several web servers software applications such as Internet Information Services (IIS), which comes bundled with modern versions of the Windows operating system or Apache HTTP server. using the Internet to discover the difference between uploading through a browser and a program. Make notes for future use in your coursework.
