Processor registerA processor register is a quickly accessible storage location available to a computer's processor. Registers usually consist of a small amount of fast storage, although some registers have specific hardware functions, and may be read-only or write-only. In computer architecture, registers are typically addressed by mechanisms other than main memory, but may in some cases be assigned a memory address e.g. the DECPDP-6/PDP-10 and the ICT 1900.Integer (computer science)In computer science, an integer is a datum of integral data type, a data type that represents some range of mathematical integers. Integral data types may be of different sizes and may or may not be allowed to contain negative values. Integers are commonly represented in a computer as a group of binary digits (bits). The size of the grouping varies so the set of integer sizes available varies between different types of computers.
Central processing unitCentral computer component that executes instructionsCore i9-14900KF, a 2023 CPU made by IntelInside a central processing unit: The integrated circuit of Intel's Xeon 3060, first manufactured in 2006A central processing unit (CPU), also known as a central processor, main processor, or simply processor, is the primary processor in a given computer.
Computer architectureIn computer science and computer engineering, a computer architecture is the conceptual design and operational structure of a computer system that define how component parts are organized and interact to execute programs efficiently. It is often a general description that ignores precise implementation details. It covers the instruction set architecture, CPU microarchitecture, memory, and input/output systems.
NibbleIn computing, a nibble, also spelled nybble to match byte, is a unit of information consisting of four bits, equivalent to one half of a byte or octet (data units of eight-bit length). The unit is alternatively called a nybl, half-byte or tetrad. In computer networking and telecommunications, the unit is also sometimes called a semi-octet, quadbit, or quartet.
Arithmetic logic unitCategoriesSee also FPU GPU AGUMechanical calculatorIn computing, an arithmetic logic unit (ALU) is a combinationaldigital circuit that performs arithmetic and bitwise operations on integerbinary numbers. This is in contrast to a floating-point unit (FPU), which operates on floating point numbers. It is a fundamental building block of many types of computing circuits, including the central processing unit (CPU) of computers, FPUs, and graphics processing units (GPUs).
Bus (computing)In computer architecture, a bus (historically also called a data highway or databus) is a communication system that transfers data between components inside a computer or, more rarely, between computers. It encompasses both hardware (e.g., wires, optical fiber, bus slots) and software, including communication protocols. At its core, a bus is a shared physical pathway, typically composed of wires or traces on a circuit board, that allows multiple devices to communicate.
BitThe bit is the most basic unit of information in computing and digital communication. The name is a portmanteau of binary digit. Its symbol is either "bit" (IEC standard) or lowercase "b" (IEEE standard). Use of the latter may create confusion with capital "B", which is the international standard symbol for the byte. The bit represents a logical state with one of two possible values.
Cash registerA cash register, sometimes called a till or automated money handling system, is a mechanical or electronic device for registering and calculating transactions at a point of sale. It is usually attached to a drawer for storing cash and other valuables. A modern cash register is usually attached to a printer that can print out receipts for record-keeping purposes.
EM MicroelectronicEM Microelectronic, based in near Neuchâtel in Switzerland, is a developer and semiconductor manufacturer specialized in the design and production of ultra low power, low voltage integrated circuits for battery-operated and field-powered applications in consumer, automotive and industrial areas. It is a subsidiary of The Swatch Group. HistoryEM began as a division of and was founded in 1975. In August 2022, they partnered up with Exeger, a manufacturer of solar cells.
CalculatorA calculator is typically a portable electronic device used to perform calculations, ranging from basic arithmetic to complex mathematics. The first solid-state electronic calculator was created in the early 1960s. Pocket-sized devices became available in the 1970s, especially after the Intel 4004, the first microprocessor, was developed by Intel for the Japanese calculator company Busicom.
Digital dataDigital data or digital information, in information theory and information systems, is data or information represented as a string of discrete symbols, each of which can take on one of only a finite number of values from some alphabet, such as letters or digits. An example is a text document, which consists of a string of alphanumeric characters.*As an Amazon Associate I earn from qualifying purchases.
