Apple Watch S11 Titanium Gold Cellular 42 mm (gold Milanese loop)

Brightness is the amount of radiating light emitted from the screen. The brightness rating is measured in candellas per square meter, commonly known as 'nits'.

Type of display (screen) e.g. LCD.

The number of distinct pixels in each dimension that can be displayed. It is usually quoted as width × height, with the units in pixels: for example, "1024 × 768" means the width is 1024 pixels and the height is 768 pixels. The higher the number of pixels, the sharper the image.

A screen of a laptop, smartphone, etc., that responds to touch so you can control the interface using your fingers.

The manufacturer that produced the processor.

The model number for the processor in a computer.

The number of central processing units ('cores') in a processor. Some processors have 1 core, others have 2 (e.g. Intel Core Duo) or more (e.g. the Intel Xeon E7-2850 has 10 cores).

The external form, contours, or outline of the product.

Under which category can the device be positioned in the market, e.g. camera phone.

The colour of the band, also known as the strap, of watches etc.

Physical effects from which the product is protected e.g. water resistant, crash proof.

The IP code classifies and rates the degree of protection provided against the intrusion (including body parts such as hands and fingers), dust, accidental contact, and water by mechanical casings and electrical enclosures. It is published by the International Electrotechnical Commission (IEC). The digits (characteristic numerals) indicate conformity with the conditions summarized in the tables below. Where there is no protection rating with regard to one of the criteria, the digit is replaced with the letter X. an electrical socket rated IP22 is protected against insertion of fingers and will not be damaged or become unsafe during a specified test in which it is exposed to vertically or nearly vertically dripping water. Another example is the Sony Xperia Z Ultra, one of the first cellular phones to be IP-rated; it is rated at IP58 and marketed as "dust resistant" and can be "immersed in 1.5 meter of freshwater for up to 30 minutes".

Frequency-modulated (FM) radio gives the clearest reception of any radio band. When used with a headset, it delivers stereo-like sound.

The operating systems e.g. Android, iOS, that can be used with the mobile device.

Type of operating system on a device e.g. IOS on Apple devices, Android for mobile devices.

The use of processors that have datapath widths, integer size, and memory addresses widths of 64 bits (eight octets). In 2003 64-bit CPUs were introduced to the (previously 32-bit) mainstream personal computer arena in the form of the x86-64 and 64-bit PowerPC processor architectures and in 2012 even into the ARM architecture targeting smartphones and tablet computers, first sold on September 20, 2013 in the iPhone 5S powered by the ARMv8-A Apple A7 SoC.
