Technology is full of jargon, and it changes continuously. If you are new to computer networking, it can be tricky to know where to start. So we’ve put together this handy guide to Tech Jargon.
What Is “Tech Jargon” And Why Do You Need It?
Jargon is the name for any particular words or phrases that professional use to define parts of the industry or profession.
Jargon has got a bit of a bad rap over the last few years. Some specialists use them to baffle that outside of the industry.
We are in constant contact with “tech people” every day. With the continued rise of Silicon Valley bosses appearing on TV, IT professional in every and the many, many tech hustlers we felt it’s time to dip into the tech jargon to enlighten us all!
However, at Comms Express, we are proud to have a supportive team who can guide even the most technophobic users. So we have set about creating this guide to all the tech jargon this industry might throw at you. If you take a look at our InfoZone, you’ll find a plethora of useful articles around different parts of the industry.
But here is a quick breakdown of terms.
Glossary of Terms

Malware: Software which damages a computer or gains access to the network system.
Megabyte: equal to 1,048,576 bytes
Modem: A modem takes data from the ISP through the cable into your home (usually a phone line or fibre optic cable). The modem then converts it into a digital signal and sends it to the router.
Network: A group of computers connected to each other so they can share data, devices or other resources.
Network Attached Storage (NAS): A device which connects to a computer network that allows users to store data. This NAS can be accessed by those connected to it, almost like cloud storage.
