Domain names

The domain name system is essentially a hierarchical distributed naming system for computers, services or any resource connected to the internet or a private network. It associated various information which the domain names instead of the IP addresses. An IP address were a series of numbers and letters. The users of the internet would have to remember these to get onto a particular page, whereas now they only have to remember a name which is much easier.

These domain name servers made the internet able to access the pages we want as quickly as we do know. This is how the domain name server helped to contribute to the technological growth of the internet, with the speed. We only have the speeds which we know and expect of our internet because of domain names. 

Technological growth - Packet switching

The first concept of sending small blocks of data was originally explored by Paul Baran in the early 1960s. The idea of sending information in packets was coincidentally also developed in the UK a few years later by Donald Davies and the National Physical Laboratory.

Packet switching is where a piece of information is split up into multiple packets. Each of these smaller packets is assigned a ‘header’.  The header contains a network IP address, which it needs to arrive to and it also has the details of the IP address from which it was sent so that if anything goes wrong it can be returned safely. The header also gives each packet a number and records how many packets the data was split up into, this allows for the maximum security which it can do.

This has contributed to the growth of the internet because it has allowed for a much securer connection  for sending you personal details over the internet and has also widened what we use the internet for.
