In computer science, 64-bit computing refers to a microprocessor 's data stream. It means an operating system can use more computer memory at one time. This makes a 64-bit system much faster than a 32-bit system. A 32-bit system can only use up to 3.56 gigabytes of random-access memory (called RAM or memory).

- I've notice the following two sentences stating somewhat conflicting information: 1. In the introduction paragraph: Hence, a processor with 64-bit memory addresses can directly access 264 bytes (=16 exabytes) of byte-addressable memory. 2. In "Limits of processors": In principle, a 64-bit microprocessor can address 16 EiBs (16 × 10246 = 264 = 18,44...

AMD64 (also variously referred to by AMD in their literature and documentation as “AMD 64-bit Technology” and “AMD x86-64 Architecture”) was created as an alternative to the radically different IA-64 architecture designed by Intel and Hewlett-Packard, which was backward-incompatible with IA-32, the 32-bit version of the x86 architecture. Originally announced in 1999 with a full specification available in August 2000, the AMD64 architecture was positioned by AM…

- In computer architecture, 64-bit computing is the use of processors that have datapath widths, integer size, and memory addresses of 64 bits (8 octets) wide. Also, 64-bit CPU and ALU architectures are those that are based on registers, address buses, or data buses of that size. From the software perspective, 64-bit computing means the use of code w...

64位元CPU是指CPU内部的通用暫存器的宽度为64 位元，支持整数的64比特宽度的算术与逻辑运算。 早在1960年代，64位架构便已存在於当时的超級電腦，且早在1990年代，就有以RISC為基礎的工作站和伺服器。 2003年才以x86-64和64位元PowerPC處理器架構的形式引入到（在此之前是32位元）個人電腦領域的主流。

Uses. While 32- and 64-bit processors are more prominent in modern consumer electronics, 4-bit CPUs can as of 2021 be bought online at down to $0.23 (in bulk for 1000 units, or at $0.70 for one of the same kind or $2.55 for a different kind), while an 8-bit microcontroller can be bought for $0.24 for a single one (also obsolete; and a non-obsolete 8-bit CPUs can be bought for $0.30 …

16-bit architecture. The MIT Whirlwind (c. 1951) was quite possibly the first-ever 16-bit computer. It was an unusual word size for the era; most systems used six-bit character code and used a word length of some multiple of 6-bits. This changed with the effort to introduce ASCII, which used a 7-bit code and naturally led to the use of an 8-bit multiple which could store a single …

A 32-bit file format is a binary file format for which each elementary information is defined on 32 bits (or 4 bytes). An example of such a format is the Enhanced Metafile Format.

Rosetta 2 adds support for x86-64 applications but not virtualization of x86-64 computer platforms. Porting to 32- or 64-bit ARM operating systems. Windows applications recompiled for ARM and linked with Winelib, from the Wine project, can run on 32-bit or 64-bit ARM in Linux, FreeBSD, or other compatible operating systems.
