Using processing rather than optics to produce an image — capturing multiple frames and combining them computationally, which is how a phone with a tiny lens produces photographs a small sensor
Yes, by a considerable margin — and the megapixel number is the figure most heavily marketed and least informative about image quality. What megapixels actually determine. How many pixels the image
Parking mode records or monitors while the vehicle is switched off and unattended, which is when a substantial proportion of incidents — hit-and-runs in car parks, vandalism, theft — actually occur.
A surge protector defends against voltage spikes. A UPS additionally provides battery power when the mains fails. They solve different problems, and many people buy the first believing they have the
Firmware is the low-level software controlling hardware directly — the code that runs before and beneath any operating system. Updating it changes how the device fundamentally behaves. Where firmware
E-ink (electrophoretic display) is a fundamentally different display technology from the LCD or OLED in a tablet, and that difference explains every characteristic of an e-reader. How e-ink works.
Through one of three navigation approaches, and the difference between them determines almost everything about how well the machine works. Random or bump navigation. The cheapest approach — the robot
A hub is a central device that connects smart home products, translates between their different protocols, and lets them work together. Matter is a standard intended to make that translation
The categories describe what connects to what, and each involves a genuine trade-off rather than one being simply better. Wired. A physical cable to the device. Advantages: no battery, so they never
Colour gamut is the range of colours a display can reproduce. It matters enormously for some work and barely at all for others, and the specification is frequently misrepresented. The main colour
They are suffixes indicating the power and thermal class of the chip, and they matter considerably more than the model number for how a laptop actually performs. Intel's laptop suffixes, roughly by
Integrated graphics share the main processor's silicon and the system's memory. Discrete graphics is a separate chip with its own dedicated memory. Integrated (iGPU). Built into the CPU package. It
Yes, noticeably — and it is one of the few specification upgrades most people perceive immediately, though it comes with a real cost. What refresh rate is. The number of times per second the display
It depends almost entirely on screen size and viewing distance, and for most living rooms the honest answer for 8K is no. The terms first. 4K in consumer televisions means UHD, 3840 × 2160 — four
A codec determines how audio is compressed for transmission over Bluetooth, and it matters — though less than headphone quality, fit and the source recording. Why compression is necessary. Bluetooth
A NAS (network attached storage) is a small dedicated computer containing one or more drives, connected to your network rather than to a single machine. An external drive connects directly to one
Because the printer and the ink are sold as a linked system, priced so that the consumable carries the profit. The economics are deliberate rather than accidental. The razor-and-blades model. Inkjet
Burn-in is permanent image retention — a faint ghost of static content remaining visible after the content changes. It is caused by uneven ageing of the display's light-emitting elements rather than
Partly. Some of it is documented and deliberate; much of what is attributed to it has duller explanations. Separating them matters because the remedies differ. What is genuinely documented: The
They describe increasing levels of spatial audio capability, and the labels are used loosely enough that a box saying "Atmos" may deliver very little of it. Stereo (2.0) — two channels, left and
For most homes with coverage problems, yes — and the difference is architectural rather than a matter of power. How a range extender works. It receives the router's signal and rebroadcasts it. The
Usually yes after a couple of years, and the reason is that the television and the software inside it have very different useful lifespans. The core problem with built-in platforms. A TV is expected
You can, and for some uses it works well — but several differences make a TV a poor desk monitor and a good living-room display, and they are not obvious from the specifications. Where TVs fall
For most people, in most listening situations, the evidence for hearing a difference above CD quality is weak — though the surrounding claims are often confused with things that genuinely do matter.
