What is RAM?
RAM (Random Access Memory) is different to the permanent storage provided by hard disk drives (HDD), solid state drives (SSD) or memory cards in your equipment. RAM is used by your device to temporarily store data to carry out everyday operations. The more RAM your machine has, the faster you can expect it to open and run programs.

This device has 8GB RAM.

Solid state drive
The solid state drive (SSD) in this computer gives you capacity to store your documents and media, while ensuring speedy and dependable access to your files and programs. SSDs are much faster than regular hard drives and don't use moving parts to work, making them more reliable and quieter.

Colour-matched mouse and keyboard
iMac now features a colour-matched keyboard, mouse and trackpad to complete the look. Magic Keyboard has keys for Spotlight, Dictation, Do Not Disturb, emoji, and for the first time: Touch ID. Touch ID enables you to easily and securely unlock your computer, use Apple Pay and download apps quickly – with just a tap of your finger.

Retina display

Your images will shine with a brilliant 500 nits of brightness, whilst its anti-reflective coating will provide comfort and readability. Helpfully, True Tone technology automatically adjusts the colour temperature of your display to the ambient light of your environment, for a more natural viewing experience.

Connecting your other devices
The Thunderbolt / USB 4 ports allow for fast data transfer, as well as the option for dual screen working, whilst Bluetooth can help your send data wirelessly between devices.
