Advanced Configuration and Power Interface (ACPI) is an open standard that operating systems can use to discover and configure computer hardware components, to perform power management (e.g. putting unused hardware components to sleep), auto configuration (e.g. Plug and Play and hot swapping), and status monitoring.
M.2, pronounced m dot two [1] and formerly known as the Next Generation Form Factor (NGFF), is a specification for internally mounted computer expansion cards and associated connectors. M.2 replaces the Mini SATA ( mSATA ) standard and the Mini PCIe ( mPCIe ) standard (which is how it got the short name of M dot 2 from being Mini SATA 2).
The M3's Unified Memory Architecture (UMA) is similar to the M2 generation; M3 SoCs use 6,400 MT/s LPDDR5 SDRAM. As with prior M series SoCs, this serves as both RAM and video RAM. The M3 has 8 memory controllers, the M3 Pro has 12 and the M3 Max has 32. Each controller is 16-bits wide and is capable of accessing up to 4 GiB of memory. [14]
The pascal (Pa) or kilopascal (kPa) as a unit of pressure measurement is widely used throughout the world and has largely replaced the pounds per square inch (psi) unit, except in some countries that still use the imperial measurement system or the US customary system, including the United States.
Apple released the MacBook Air with the Apple M1 system on a chip in November 2020, at WWDC20. A redesigned model based on the Apple M2 chip was released in July 2022, and the first 15-inch MacBook Air was released in June 2023. [4] In March 2024, Apple introduced M3 chip-equipped MacBook Airs in both their 13- and 15-inch sizes. [5]

Apple M2 is a series of ARM-based system on a chip (SoC) designed by Apple Inc., launched 2022 to 2023. It is part of the Apple silicon series, as a central processing unit (CPU) and graphics processing unit (GPU) for its Mac desktops and notebooks , the iPad Pro and iPad Air tablets , and the Vision Pro mixed reality headset.
HP planned to use Spectrum to move all of their non-PC compatible machines to a single RISC CPU family. In early 1982, work on the Precision Architecture began at HP Laboratories, defining the instruction set and virtual memory system. Development of the first TTL implementation started in April 1983. With simulation of the processor having ...
