In computer architecture, 64-bit integers, memory addresses, or other data units are those that are 64-bit wide. Also, 64-bit central processing unit and arithmetic logic unit architectures are those that are based on processor registers, address buses, or data buses of that size. 64-bit microcomputers are computers in which 64-bit microprocessors are the norm.

Em informática, 64 bits é o termo usado para designar dispositivos (normalmente processadores) que trabalham com um conjunto de 64 bits por vez. Um bit é a menor 'quantidade' de dados da informática, podendo ser 0 ou 1 (normalmente representado em eletrônica digital pela variação de tensão elétrica, ex: 3 volts = 0 e 5 volts = 1).. Na Arquitetura da computação, …

A 64-bit computer is not twice as fast as its 32-bit predecessor. The 64 bit "word size" is only one aspect of internal processing. The CPU's clock speed, along with the speed of storage, RAM and ...

In der Informatik wird die auf dem x86-Befehlssatz (bzw. Befehlssatzarchitektur, englisch Instruction Set Architecture, kurz: ISA) basierende 64-Bit-Architektur als x64, alternativ auch als x86-64 (auch in der Schreibweise „x86_64“) und AMD64 (auch in Kleinschreibung: „amd64“), bezeichnet. Die Befehlssatzerweiterung ergänzt die Intel Architecture 32-Bit, kurz IA-32, um …

Computer memory addresses start at zero and go up to the biggest number the computer can use. Older computers were limited in how much memory they could address. 32-bit computers can address up to 4GB of memory. Modern computers use 64 bits and could address up to 18,446,744,073,709,551,616 bytes = 16 exabytes of memory.

في معمارية الحاسوب, 64-بت من الأعداد الصحيحة، أو أي وحدات للبيانات غالباً تكون بسعة 64-بت (64 بت تعني 1 بت لم تستخدم). كما أن وحدة المعالجة المركزية وبنية وحدة الحساب والمنطق 64-بت مبنية على السجلات، ناقلات العناوين، أو ...

Woordbreedte is de breedte van een machinewoord in bits in een computer.Meestal is dit de woordbreedte die de microprocessor intern gebruikt om zijn berekeningen uit te voeren, ofwel de breedte van de dataregisters en het rekengedeelte.Zo zijn er 4-, 8-, 16-, 32- en 64-bitsprocessoren. Motorola heeft ooit een 1-bitprocessor ontwikkeld, die zeer populair was voor industriële …

Un microprocesseur à jeu d'instruction étendu (en anglais complex instruction set computer (CISC) ), désigne un microprocesseur possédant un jeu d'instructions comprenant de très nombreuses instructions mixées à des modes d'adressages complexes [réf. nécessaire].. L'architecture CISC est opposée à l'architecture RISC (Reduced Instruction-Set Computer) qui …
