# Basic network principles

A network is a set of hardware (PC, timing system, router, etc.) connected together and able to communicate with each other, usually via an Ethernet (wired) or Wi-Fi connection. \
A network can be simply created by two devices communicating with each other (the PC and the timing system, for example), but more often a network is preferred where all devices are connected to a switch or a router.

#### The basics

The configuration of a network must take certain prerequisites into account.

* Each device must have an address, called an IP address.
* Each IP address in a network must be unique. Do not use the same IP address twice.
* An IP address is made up of 4 numbers (each having a value between 0 and 255) separated by a period, e.g., 192.168.1.100.
* For a local network, IP addresses generally start with 192.168.x.x (This is a reserved range that is not used on the Internet).
* When two devices on a local network (for example, a PC and a timing system) want to communicate with each other, they must be in the same subnet. The first three numbers must be identical (but the fourth must be different). \
  For example : \
  timing system: **`192`**.**`168`**.**`1`**.<mark style="color:red;">`201`</mark> \
  PC 1 : **`192`**.**`168`**.**`1`**.<mark style="color:red;">`101`</mark> \
  PC 2 : **`192`**.**`168`**.**`1`**.<mark style="color:red;">`102`</mark>

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.wiclax.com/en/use-wiclax/acquisition-of-timing-data/basic-network-principles.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
