P1 Outline web architecture & components
Which enable Internet & Web Functionality e.g.
COMPONENTS
Servers - mail & Proxy: Servers are holding most of the time a large amount of data. It could be
Public that could be accessed by anyone, or could be Private that could be accessed by those who
have permission to it.
Proxy Servers are helping users to get through permissions. This is called “bypassing” websites that
are i.e.: most probably locational blocked. It helps servers to filter data and so this will make it work
faster and in a more secured way. Proxys are communicating with networks and the internet.
Routers: It provides data to different servers with the help of ISP (Internet Service Provider). This
makes users possible to connect to the internet.
Browsers – software: There are multiple browsers available for free for users. The most popular
ones are: Chrome, Firefox, Internet Explorer, Microsoft Edge etc. These Browsers open HTML files
that the websites are written in, and will be showing it to the users in a graphic way, or coded way.
E-mail – software: “E-mail-Electronic Mail”. Email software are used to send/receive messages, files
over on the internet. There are different Email clients that anyone can use for free such as: Gmail,
Hotmail (Outlook) etc.… You can send any type of personalised messages as long as you, and the
other participant have an email address, and you also know these addresses.
Protocols (at least 3) – from TCP/IP ; Application:
Layer e.g. HTTP, HTTPs, SMTP
TCP/IP: “Transmission Control Protocol”/”Internet Protocol”. This is the standard language/protocol
of the internet, as everything is based on this (these) protocol(s). This makes sure that all data goes
to the right address.
HTTP: Hypertext Transfer Protocol. It is used to send and receive data/webpages on the internet.
HTTPS: The “S” stands for Secure. It is using the same method as “http” works, however this is an
ever more secured way to send and receive data; webpages on the internet. This will encrypt and
decrypt all requests made by the server or the user.
SMTP: Simple Mail Transfer Protocol. As its name indicates, it is using different type of protocols to
send and receive emails with the help of the email servers.
Html: Hypertext Mark-up Language. It is a quiet easy language which gives a lot of powers to users
to create websites. This simple language is used to write websites. All websites are written in HTML.
