The Apple II, also introduced in 1977, was noted for its switched-mode power supply, which was lighter and smaller than an equivalent linear power supply would have been, and which had no cooling fan. The switched-mode supply uses a ferrite-cored high frequency transformer and power transistors that switch thousands of times per second. By ...
The top and side of an iPhone 5S, externally identical to the SE (2016).From left to right, sides: wake/sleep button, silence switch, volume up, and volume down. The touchscreen on the iPhone has increased in size several times over the years, from 3.5 inches on the original iPhone to iPhone 4S, to the current 6.1 and 6.9 inches on the iPhone 16 and 16 Pro Max series.

The switch does not fully disconnect the device from its power supply. This may appear on a toggle switch opposite a power on symbol, alone on a pushbutton that places the device into a standby state, or alone on a button that switches between on and standby. Alternatively, under IEEE 1621, this symbol simply means "power". [9]
A known failure mode of Lightning plugs is power contacts turning black over time, sometimes causing the affected side of the connector to cease functioning. When the plug is inserted or unplugged while powered, a brief spark may occur between the mating power contacts in the plug and socket, eroding their gold plating. Because the Lightning ...
Game consoles have long used specialized and customized computer hardware with the base in some standardized processor instruction set architecture. In this case, it is PowerPC and Power ISA, processor architectures initially developed in the early 1990s by the AIM alliance, i.e. Apple, IBM, and Motorola.
The computer makes use of this to retrieve information about the power adapter and to change the color of the LEDs on the power adapter's connector. The Apple MagSafe power adapter's 1-Wire communication chip is located inside the MagSafe connector itself; the cable does not carry the data line to the power adapter enclosure. [18]
EU common external power supply components EU common external power supply with captive cable. A common EPS must include a cable with a micro USB-B (2.0) connector for connecting to a mobile phone. This cable can be either captive (permanently attached to the power supply) or detachable. If detachable, the cable must connect to the power supply ...
Apple silicon is a series of system on a chip (SoC) and system in a package (SiP) processors designed by Apple Inc., mainly using the ARM architecture.They are the basis of Mac, iPhone, iPad, Apple TV, Apple Watch, AirPods, AirTag, HomePod, and Apple Vision Pro devices.
