Learn to Talk Tech with Our IT Jargon Buster Our A–Z of Some of the Terms You Might Hear when Talking with an IT Expert

A few words of a foreign language can get you a long way in a strange land.

We know that IT jargon is an alien language to a lot of people, and we do our best to keep the tech talk to a minimum when we’re working with our clients.

In any case, you probably have enough of your own office jargon to start worrying about ours.

But in a tech-led world, a lot of IT terms are cropping up more and more in everyday conversation. And if you do have a problem you need help with – or just a question you’d like to ask us about your business IT – it’ll save a lot of time if you have a few words of lingo in your locker.

Our new guide is a great place to start. It won’t tell you everything, but if you need an easy A-Z of some of the most common terms you’ll hear when you’re talking with an IT expert, then you’ve come to the right place.

Let’s start at the beginning…


  • Adware—Software that automatically downloads adverts when you’re online, such as banner ads and pop-ups
  • AI (Artificial Intelligence)—Systems and devices that simulate human behaviors and decisions. This can include creating systems, language processing, speech recognition, writing text and machine vision
  • Antivirus—Software that identifies and removes viruses from your device. Also known as anti-malware
  • API (Application Programming Interface)—Software that allows two or more applications or programs to communicate with each other and share information


  • Backdoor—A vulnerability in a security system that allows unwanted access to files and data
  • Bandwidth—The maximum amount of data you can send and receive in a given amount of time, over an internet connection. Imagine a big pipe compared with a small pipe
  • Botnet—A network of private computers infected with malware and controlled as a group to spread the virus further


  • Cache—A temporary file that stores information on your device to speed things up. For instance a web cache might remember the last thing you were doing so it can reload a page where you left off
  • (The) Cloud—Data storage and computing power that lives on remote servers, which are accessed via the internet
  • Corrupted—An unstable data file
  • Cybersecurity—Any and all security measures put in place to protect your devices, systems and network from cyber attack


  • Darkweb—A hidden part of the internet, accessed using special software. It’s rife with criminal activity. This is where stolen data, such as credit card details, is often sold
  • Data breach—A security incident where private data is viewed or stolen by unauthorized persons
  • DDoS (Distributed Denial of Service)—A type of cyber attack that harms or stops a network by flooding it with data from numerous other devices
  • Downtime—The period of time a network or systems are offline (or ‘down’), preventing the normal running of a business


  • Encryption—The process of encoding data to make it unreadable without the right access information - usually a password, passkey or authentication app

  • HTML (Hypertext Markup Language)—The universal language of the internet, used to structure web pages, tell your web browser how to display them and create links between them

  • iOS—Operating system manufactured by Apple and used exclusively on its hardware
  • IP (Internet Protocol) address—A unique number that identifies a device connected to the internet


  • Java—A widely used programming language used in millions of applications and devices around the world


  • Keylogger—Software used by cybercriminals to record the keys pressed on a keyboard. This information can be used to access login credentials and other sensitive information


  • LAN (Local Area Network)—A network of connected devices that spans a small area, such as your office or home

  • Protocol—The set of rules that allows different devices to communicate with each other
  • Proxy Server—A server that sits between a device requesting information, and the server providing that information. For example, it could be a gateway between your laptop and the internet, that stops hackers from reaching your network


  • RAM (Random Access Memory)—A form of temporary computer memory that’s usually used to store working data
  • Ransomware—Malware that encrypts sensitive data and demands a ransom for its release (ransoms should never be paid – data is often never properly released, or is only partially returned)
  • Router—A device that directs data to the right places in a network


  • Server—A computer or program that manages access to a network and holds data in one location for multiple users to access
  • Software—Programs and apps that make devices work
