IT words, in farm English.

Mobile internet. With an aerial on the outside wall and a router inside, it can beat a poor phone line.

A small box, often on a ceiling or wall, that makes Wi-Fi where the router can't reach. Wired back to the router for the best results.

A camera built to read number plates, day and night, at the entrance to the yard.

A second copy of your files, kept somewhere else, that you've actually tested you can get back.

A battery that keeps the router, the phone or the cameras running through a power cut.

A radio amateur's own name on the air, issued with the licence. Like a number plate for your voice.

Phone calls carried over your broadband instead of the old copper line. Where every UK landline is heading by January 2027.

Your own name on the internet, like yourfarm.co.uk, for a website and email addresses that are yours, whoever your provider is.

The cable with the chunky square plug that connects things to the network. Faster and steadier than Wi-Fi, every time.

A second connection, often 4G, that takes over by itself when the main one drops, and hands back when it returns.

A gatekeeper between your network and the internet, letting your traffic out and keeping strangers out.

Broadband on a glass fibre all the way to the building. The fastest and most reliable kind, where it has reached.

The long-distance radio bands. The signal bounces off the upper atmosphere and comes down hundreds or thousands of miles away.

The number each device has on a network, like a house number, so information gets to the right one.

Whether one dish can 'see' the other. Hills, trees and barn roofs in between block the beam, so Daniel checks the actual path.

A radio network for small sensors that send a little information a long way on a battery that lasts years. Water troughs, grain stores, gates.

HMRC's rule that sole traders and landlords over a set income keep digital records and send quarterly updates through software.

How fast the internet is. 10 is workable, 30 is comfortable for a farm office, 300 and up is full fibre.

Several access points working as one network, so your phone moves from one to the next without dropping, like a relay team passing the baton.

Microsoft's email, Word, Excel and file storage, by monthly subscription. The same for one farm office as for a bank.

The part that turns the signal on the phone line, fibre or satellite into internet. Usually hidden inside the router these days.

The box that records the CCTV cameras. Keep it locked away, so taking the camera doesn't take the evidence.

An app that remembers a strong, different password for everything, so you only have to remember one.

A fake email, text or call pretending to be your bank, HMRC or a supplier, to get your details or your money.

Licence-free two-way radios: half a watt and a fixed aerial. Fine across the yard, not much further.

Power sent down the network cable along with the data, so a camera or access point on a barn wall needs no plug socket.

A pair of small dishes that beam the internet from one building to another, across the yard or across two fields. A cable without the trench.

The old landline network, powered from the exchange. It closes on 31 January 2027.

Nasty software that locks up your files and demands money to unlock them. Good backups take its teeth out.

A radio on a hilltop or a tall building that picks up handhelds and sends them on, far further than they'd reach alone.

The box the internet comes into the house through. Everything else on the network goes through it, like the farm gate.

A modern storage drive with no moving parts. Swapping one into an old laptop makes it feel years younger.

Broadband from satellites, through a dish that needs a clear view of the sky. Life-changing where the phone line is hopeless.

Fibre to the green cabinet in the village, then the old copper phone line for the last stretch. Good near the cabinet, worse the further you are.

Someone else's computers, in a data centre, that keep your files and email so you can reach them from anywhere.

A code from your phone on top of your password, so a stolen password alone gets a thief nowhere.

Download is the internet coming to you; upload is you sending to it. Cameras that send video to your phone need upload.

The local radio bands, used by handhelds, repeaters and farm two-way radios. They travel in straight lines, so height matters more than power.

One set of kit split into separate networks, so the cameras, the guests and the office can't see each other. Like separate pens in one shed.

A private tunnel through the internet, so you can reach the farm network safely from somewhere else.

The newer kinds of Wi-Fi: faster, and better when lots of devices are connected. Your devices need to support it to benefit.
