If you've heard of Network Attached Storage - sometimes shortened to NAS - but aren't sure what it's all about, then read on for our quick guide to the basics...

What is Network Attached Storage (NAS)?

We all know we can connect a USB External Hard Drive to our computer and immediately create additional storage for data or backup, but when it comes to efficient data management, there is perhaps a better way… to use Network Attached Storage or NAS for short.

Why Choose Network Attached Storage (NAS)?

External Hard Drives are a great way to quickly and conveniently create additional storage via a simple USB connection to your computer. However such devices are often restricted to use at the specific computer to which they’re connected and by the specific person using that computer. All good and well, but what if you need to share the content and files?

The answer lies in Network Attached Storage. Instead of connecting directly to an individual desktop or laptop computer, a NAS server connects to your wireless router. This effectively allows multiple users from multiple computers to access and share the content and files stored on it. Just one copy of your files, in one accessible place!

Power-line communication (PLC) is a communication protocol that uses electrical wiring to simultaneously carry both data, and Alternating Current (AC) electric power transmission or electric power distribution. It is also known as power-line carrier, power-line digital subscriber line (PDSL), mains communication, power-line telecommunications, or power-line networking (PLN).

A wide range of power-line communication technologies are needed for different applications, ranging from home automation to Internet access which is often called broadband over power lines (BPL). Most PLC technologies limit themselves to one type of wire (such as premises wiring within a single building), but some can cross between two levels (for example, both the distribution network and premises wiring). Typically transformers prevent propagating the signal, which requires multiple technologies to form very large networks. Various data rates and frequencies are used in different situations.

A number of difficult technical problems are common between wireless and power-line communication, notably those of spread spectrum radio signals operating in a crowded environment. Radio interference, for example, has long been a concern of amateur radio groups.^[1]
