The modern home network developed over the years firstly as a method to share one internet connection between multiple devices in a home. When broadband internet was first released in Australia (ADSL – Cable), Internet Service Providers or ISP’s only offered modems with a single Ethernet port and no WiFi.
Modems offered a single port to access the internet and lacked WiFi capabilities – while this was a viable solution for users with only one PC, the majority of users had more than one device capable of connection to the internet and wanted internet access on all devices.
In order to connect more than one device to the internet, users could purchase a third party router and configure it to access the internet through the ISP supplied modem. While this solution did work ISP’s did not support it and refused to offer any technical support unless only the modem was connected.
As networking equipment developed and public demand increased, ISP’s began offering Modem-Routers as a solution to share an internet connection between all devices.
Over time more network capable devices have been released such as Printers, Media Servers etc..
When you consider all the electronic devices people use today from smartphones, laptops, computers, tablets, internet television etc… it can become confusing as to where you saved a certain picture or movie for example. By connecting devices such as printers to the network, all computers and devices can share use of the device.
By networking all of your devices together, you can save all your data on one location such as a PC (Personal Computer) or NAS (Network Accessible Storage) and access the same data from all of your devices.
This makes it much easier to manage and backup your data, instead of having multiple different copies of files stored in different locations, all the data is stored in one central location and all users access the same data.
