Localhost

What do you need a localhost for? Sometimes it can be useful to communicate with yourself. This is known as a loopback in network technology: instead of feeding a request to the network – e.g. the internet – you instead keep it within your system, subsequently stimulating a network connection. We will explain how the connection to 127.0.0.1 works, and what you can use localhost for.

The different network types

When several computers are connected to one another it is known as a network. Networks enable data exchange between different devices, making shared resources available. Different network types are implemented depending on which transmission techniques and standards are used. These differ in terms of the number of connected systems and potential reach.

Network protocol: Standards for data exchange

For computer systems to be able to communicate with each other and exchange information, they need common ground, just like humans must share a common language. But computers don’t rely on foreign language lessons, and instead only need the appropriate network protocol to successfully communicate. This provides guidelines and structures for the data transfer, and so plays a decisive role in the...
