The instruction set architecture (ISA) is a set of commands used by the software to manage the CPU's work. Information about the set of instructions the processor can execute. This gives a perception of quality and an appeal that is not directed to men or women, it is a universally acceptable colour choice that will look at home in any bathroom. This too acts as a pressure sensor, illuminating red when activated and will at other times (when powered on) shine one of 12 different colours set by you through the Oral-B app. What is known as a quad-pacer that is built into the Smart 7, will at 30 second intervals pause the motion of the brush head briefly to give you the notification you need to change quadrant. The LED smart Ring also flashes. This happens at 30 second intervals, up until the 2 minutes where you get 3 brief pauses in the brush head motion and 3 LED flashes, to tell you to stop. The color depth of the display is also known as bit depth. It shows the number of bits used for the color components of one pixel. Information about the maximum number of colors the screen can display.

One of the main characteristics of the display is its type/technology, on which depends its performance. The SMART7 multi-frequency SMART Antenna combines a NovAtel OEM7 ® receiver and precision antenna in a durable and waterproof enclosure. Access to multiple GNSS signals allow for better satellite availability under variable terrain and environmental conditions. The SMART7 also receives L-Band signals to access world-wide correction signals provided by TerraStar. All brush heads made by Oral-B feature something known as fading/indicator bristles. Blue in colour, over the 3 month period in which a brush should be used, they fade in colour to a white/translucent colour, acting as a reminder to replace the head. It is by no means a new addition, but one reason why Oral-B is one of the market leaders is that research has shown that their rounded, oscillating and rotating brush heads are very effective at cleaning the teeth. All told there is a lot to like about the Smart 7 and what criticisms I have are, to be honest, limited.So, time to talk about one of the biggest features and selling points for this brush, the app and Bluetooth connectivity.

The new Multiple profiles plugin allows you to create Relationship types that cross-over your various profiles. Generally speaking, the weakest point is the battery. After repeated charges and discharges it can fail and should it, they are not easy to replace. Thankfully the lithium-ion battery technology now used in the 7000 is a step up over the old battery technology and should further improve long term reliability from the internal power source.The body of the handle is primarily white in colour with the main colour accent being the front of the brush with the silver/blue insert.

This has changed more recently as the brand switches from NiMH to Lithium-ion. Lithium batteries are the same technology as used in your smartphone and boast an extended battery life compared to the NiMH batteries.Included in the box is a charging stand that you can leave the 7000 sat on when not in use if you want.

Similar to the CPU, the GPU consists of processing units called cores. They handle the computation of graphics in various applications. I fear though, as good as the app is, unless you really invest time and effort into getting into the routine of using it, it's all too easy to forget about. Other additions in the box include the brush charging stand.Reliability is something that we expect in products, but the fast moving consumer goods are often prone to cost saving measures and putting out ‘cheap’ products to maximise profits. Both smartphones- Smart 7 Plus and Smart 7HD boast of a large 6.6-inch full-view display with HD+ high resolution and advanced thin edges. This makes the smartphones ideal for viewing videos and images. Dr. Gemma Wheeler has looked in detail at the environmental impact of electric toothbrushes.
