Components that make the Web Work

2.1-  Describe how hardware and software components            make the web work

Hardware components that make the web work

  • Clients used to access web content (computers, laptops, mobile phones, smart TVs, games consoles, internet of things (IoT devices)).

​

  •  Servers used to store and process information (file, email, web, proxy, application, DNS).

​

  •  Nodes used to transmit data across the network (routers, switches, phone lines, wireless connections).

​​

  • Protocols used to set the rules on how components communicate with each other across the network by defining the method and language in which to transmit data.

DNS

Domain name system

DNS?

Software components that make the web work

  • ​Browsers.

​​

  • Representation formats of web pages (HTML, CSS, XML).

​​

  • Applications (web, desktop and mobile). Protocols (HTTP, FTP).

​​

The domain name system (DNS) is a naming database in which internet domain names are located and translated into internet protocol (IP) addresses. 

Process to enable web communications

  • Clients send requests for data via Internet Service Providers (ISP).

​​

  • Internet Service Providers forward requests for data via multiple Domain Name Servers (DNS).

​​

  • Internet Protocol (IP) address of the destination servers are found.

​​

  • Servers respond by sending files in a series of packets.

​​

  • A packet contains headers and footers with information about the data and how to reconstruct itself with other packets once it reaches the clients.

​​

  • Data is received and interpreted by the clients​
