Bit Bucket
In computing jargon, the bit bucket (or byte bucket) is where lost computerized data has gone, by any means; any data which does not end up where it is supposed to, being lost in transmission, a computer crash, or the like, is said to have gone to the bit bucket – that mysterious place on a computer where lost data goes, as in: History Originally, the bit bucket was the container on teletype machines or IBM key punch machines into which chad from the paper tape punch or card punch was deposited; the formal name is "chad box" or (at IBM) " chip box". The term was then generalized into any place where useless bits go, a useful computing concept known as the null device. The term bit bucket is also used in discussions of bit shift operations. The bit bucket is related to the first in never out buffer and write-only memory, in a joke datasheet issued by Signetics in 1972. In a 1988 April Fool's article in ''Compute!'' magazine, Atari BASIC author Bill Wilkinson prese ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Write-only Memory (joke)
Write-only memory (WOM), the opposite of read-only memory (ROM), began as a humorous reference to a memory device that could be written to but not read, as there seemed to be no practical use for a memory circuit from which data could not be retrieved. However, it was eventually recognized that write-only memory also describes certain functionalities in microprocessor systems. The concept is still often used as a joke or euphemism for a failed memory device. The first use of the term is generally attributed to Signetics, whose ''write-only memory'' literature, created in 1972 as in-house practical joke, is frequently referenced within the electronics industry,. a staple of software engineering lexicons, and included in "best hoaxes" collections. Signetics A "Write-Only Memory" datasheet was created "as a lark" by Signetics engineer John G "Jack" Curtis,. inspired by a fictitious and humorous vacuum tube datasheet from the 1940s. Considered "an icebreaker", it was deliberately inc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Intel ISIS-II
ISIS, short for Intel System Implementation Supervisor, was an operating system for early Intel microprocessors like the 8080. It was originally developed by Ken Burgett and Jim Stein under the management of Steve Hanna and Terry Opdendyk for the Intel Microprocessor Development System with two 8" floppy drives, starting in 1975, and later adopted as ISIS-II as the operating system for the PL/M compiler, assembler, link editor, and In-Circuit Emulator (developed by Steve Morse). The ISIS operating system was developed on an early prototype of the MDS 800 computer, the same type of hardware that Gary Kildall used to develop CP/M. Overview Communication with the user is terminal-like. Its user interface is somewhat CP/M-like, even from the program interface point of view. For file opening, the program sends the name of file and gets back a handle. Each device has a name, which is entered between a pair of colons (:F0: and :F1: are floppies, :LP: is printer, etc.). Each disket ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Intel Corporation
Intel Corporation is an American multinational corporation and technology company headquartered in Santa Clara, California, and incorporated in Delaware. Intel designs, manufactures, and sells computer components such as central processing units (CPUs) and related products for business and consumer markets. It is one of the world's largest semiconductor chip manufacturers by revenue, and ranked in the ''Fortune'' 500 list of the largest United States corporations by revenue for nearly a decade, from 2007 to 2016 fiscal years, until it was removed from the ranking in 2018.

Waste Container
A waste container, also known as a dustbin, rubbish bin, trash can, garbage can, wastepaper basket, and wastebasket, among other names, is a type of container intended to store waste that is usually made out of metal or plastic. The words "rubbish", "basket" and "bin" are more common in British English usage; "trash" and "can" are more common in American English usage. "Garbage" may refer to food waste specifically (when distinguished from "trash") or to municipal solid waste in general. The word " dumpster" (from a genericised trademark) refers to a large outdoor waste container for garbage collectors to pick up the contents. Designs Trash cans are typically made of steel or plastic (most commonly polyethylene), although some are made of wood or wicker. A pedal bin is a container with a lid operated by a foot pedal. Lillian Moller Gilbreth, an industrial engineer and efficiency expert, invented the pedal bin in the 1920s for the disposal of kitchen waste. The foot ped ...

Black Hole (networking)
In networking, a black hole refers to a place in the network where incoming or outgoing traffic is discarded (or "dropped" or sinkholed) without informing the source that the data did not reach its intended recipient. When examining the topology of the network, the black holes themselves are invisible, and can only be detected by monitoring the lost traffic. The name is presumed to have originated from a concept of an astronomical location, a black hole. Black holes were originally defined as astronomical locations which cannot be directly observed using the definition of the holes having gravitational fields from which light cannot escape. Since 2023 with the discovery of an accretion disk of a black hole, it has been found that electromagnetic radiation produced by the disk of the black hole is available for observation by astronomy. At least since the astronomer Heber Curtis observed during 1918 visible light from a relativistic jet produced by a black hole at the centr ...

NET Framework
The .NET Framework (pronounced as "''dot net''") is a proprietary software framework developed by Microsoft that runs primarily on Microsoft Windows. It was the predominant implementation of the Common Language Infrastructure (CLI) until being superseded by the cross-platform .NET project. It includes a large class library called Framework Class Library (FCL) and provides language interoperability (each language can use code written in other languages) across several programming languages. Programs written for .NET Framework execute in a software environment (in contrast to a computer hardware, hardware environment) named the Common Language Runtime (CLR). The CLR is an process virtual machine, application virtual machine that provides services such as security, memory management, and exception handling. As such, computer code written using .NET Framework is called "managed code". FCL and CLR together constitute the .NET Framework. FCL provides the user interface, data access, d ...

Computer Memory
Computer memory stores information, such as data and programs, for immediate use in the computer. The term ''memory'' is often synonymous with the terms ''RAM,'' ''main memory,'' or ''primary storage.'' Archaic synonyms for main memory include ''core'' (for magnetic core memory) and ''store''. Main memory operates at a high speed compared to mass storage which is slower but less expensive per bit and higher in capacity. Besides storing opened programs and data being actively processed, computer memory serves as a Page cache, mass storage cache and write buffer to improve both reading and writing performance. Operating systems borrow RAM capacity for caching so long as it is not needed by running software. If needed, contents of the computer memory can be transferred to storage; a common way of doing this is through a memory management technique called ''virtual memory''. Modern computer memory is implemented as semiconductor memory, where data is stored within memory cell (com ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bitstream
A bitstream (or bit stream), also known as binary sequence, is a sequence of bits. A bytestream is a sequence of bytes. Typically, each byte is an 8-bit quantity, and so the term octet stream is sometimes used interchangeably. An octet may be encoded as a sequence of 8 bits in multiple different ways (see bit numbering) so there is no unique and direct translation between bytestreams and bitstreams. Bitstreams and bytestreams are used extensively in telecommunications and computing. For example, synchronous bitstreams are carried by SONET, and Transmission Control Protocol transports an asynchronous bytestream. Relationship to bytestreams In practice, bitstreams are not used directly to encode bytestreams; a communication channel may use a signalling method that does not directly translate to bits (for instance, by transmitting signals of multiple frequencies) and typically also encodes other information such as framing and error correction together with its data.

Programming Language
A programming language is a system of notation for writing computer programs. Programming languages are described in terms of their Syntax (programming languages), syntax (form) and semantics (computer science), semantics (meaning), usually defined by a formal language. Languages usually provide features such as a type system, Variable (computer science), variables, and mechanisms for Exception handling (programming), error handling. An Programming language implementation, implementation of a programming language is required in order to Execution (computing), execute programs, namely an Interpreter (computing), interpreter or a compiler. An interpreter directly executes the source code, while a compiler produces an executable program. Computer architecture has strongly influenced the design of programming languages, with the most common type (imperative languages—which implement operations in a specified order) developed to perform well on the popular von Neumann architecture. ...

Write Once Read Many
Write once read many (WORM) describes a data storage device in which information, once written, cannot be modified. This write protection affords the assurance that the data cannot be tampered with once it is written to the device, excluding the possibility of data loss from human error, computer bugs, or malware. On ordinary (non-WORM) data storage devices, the number of times data can be modified is limited only by the lifespan of the device, as modification involves physical changes that may cause wear to the device. The "read many" aspect is unremarkable, as modern storage devices permit unlimited reading of data once written. Historical exceptions include time-limited discs such as Flexplay, designed for short-term rental of movies; and early non-volatile memory technologies such as magnetic-core memory and bubble memory, from which reading data also erased it. WORM prevents important data being deleted or modified, helping to preserve its authenticity. History WORM dr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
PEEK And POKE
In computing, PEEK and POKE are commands used in some high-level programming languages for accessing the contents of a specific Memory cell (computing), memory cell referenced by its memory address. PEEK gets the byte located at the specified memory address. POKE sets the memory byte at the specified address. These commands originated with machine code monitors such as the PDP-10, DECsystem-10 monitor; these commands are particularly associated with the BASIC programming language, though some other languages such as Pascal (programming language), Pascal and COMAL (programming language), COMAL also have these commands. These commands are comparable in their roles to Pointer (computer programming), pointers in the C (programming language), C language and some other programming languages. One of the earliest references to these commands in BASIC, if not the earliest, is in Altair BASIC. The PEEK and POKE commands were conceived in early personal computing systems to serve a variet ...
