Computer Operator
A computer operator is a role in IT which oversees the running of computer systems, ensuring that the machines, and computers are running properly. The job of a computer operator as defined by the United States Bureau of Labor Statistics is to "monitor and control ... and respond to ... enter commands ... set controls on computer and peripheral devices. This Excludes Data Entry." Overview The position has evolved from its beginnings in Computer programming in the punched card era, the punched card era. A Bureau of Labor Statistics report published in 2018 showed that, in the public sector, a major employer of those categorized as ''Computer Operator'' was United States Postal Service. In the private sector, companies involved in data processing, Internet hosting service, hosting, or related services employed computer operators at an even higher rate. The states with the highest employment for computer operators, as of 2018, are: New York (state), New York, Texas, California, New ...

Computer Operator - 1992 - BLS
A computer is a machine that can be Computer programming, programmed to automatically Execution (computing), carry out sequences of arithmetic or logical operations (''computation''). Modern digital electronic computers can perform generic sets of operations known as Computer program, ''programs'', which enable computers to perform a wide range of tasks. The term computer system may refer to a nominally complete computer that includes the Computer hardware, hardware, operating system, software, and peripheral equipment needed and used for full operation; or to a group of computers that are linked and function together, such as a computer network or computer cluster. A broad range of Programmable logic controller, industrial and Consumer electronics, consumer products use computers as control systems, including simple special-purpose devices like microwave ovens and remote controls, and factory devices like industrial robots. Computers are at the core of general-purpose devices ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Remote Computer
In computing, the term remote desktop refers to a software- or operating system feature that allows a personal computer's desktop environment to be run remotely from one system (usually a PC, but the concept applies equally to a server or a smartphone), while being displayed on a separate client device. Remote desktop applications have varying features. Some allow attaching to an existing user's session and "remote controlling", either displaying the remote control session or blanking the screen. Taking over a desktop remotely is a form of remote administration. Overview Remote access can also be explained as the remote control of a computer by using another device connected via the internet or another network. This is widely used by many computer manufacturers and large businesses help desks for technical troubleshooting of their customer's problems. Remote desktop software captures the mouse and keyboard inputs from the local computer (client) and sends them to the remote ...

Computer Keyboard
A computer keyboard is a built-in or peripheral input device modeled after the typewriter keyboard which uses an arrangement of buttons or Push-button, keys to act as Mechanical keyboard, mechanical levers or Electronic switching system, electronic switches. Replacing early punched cards and paper tape technology, interaction via teleprinter-style keyboards have been the main input device, input method for computers since the 1970s, supplemented by the computer mouse since the 1980s, and the touchscreen since the 2000s. Keyboard keys (buttons) typically have a set of characters Engraving, engraved or Printing, printed on them, and each press of a key typically corresponds to a single written symbol. However, producing some symbols may require pressing and holding several keys simultaneously or in sequence. While most keys produce character (computing), characters (Letter (alphabet), letters, Numerical digit, numbers or symbols), other keys (such as the escape key) can prompt the ...

Front Panel
A front panel was used on early electronic computers to display and allow the alteration of the state of the machine's internal CPU register, registers and computer memory, memory. The front panel usually consisted of arrays of electric light, indicator lamps, digit and symbol displays, toggle switches, dials, and push-button, push buttons mounted on a sheet metal face plate. In early machines, Cathode-ray tube, CRTs might also be present (as an oscilloscope, or, for example, to mirror the contents of Williams tube, Williams–Kilburn tube memory). Prior to the development of CRT system consoles, many computers such as the IBM 1620 had console typewriters. Usually the contents of one or more hardware registers would be represented by a row of lights, allowing the contents to be read directly when the machine was stopped. The switches allowed direct entry of data and address values into registers or memory. Details On some machines, certain lights and switches were reserved f ...

Business Continuity
Business continuity may be defined as "the capability of an organization to continue the delivery of products or services at pre-defined acceptable levels following a disruptive incident", and business continuity planning (or business continuity and resiliency planning) is the process of creating systems of prevention and recovery to deal with potential threats to a company. In addition to prevention, the goal is to enable ongoing operations before and during execution of disaster recovery. Business continuity is the intended outcome of proper execution of both business continuity planning and disaster recovery. Several business continuity standards have been published by various standards bodies to assist in checklisting ongoing planning tasks. Business continuity requires a top-down approach to identify an organisation's minimum requirements to ensure its viability as an entity. An organization's resistance to failure is "the ability ... to withstand changes in its environmen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
IT Disaster Recovery
IT disaster recovery (also, simply disaster recovery (DR)) is the process of maintaining or reestablishing vital infrastructure and systems following a natural or human-induced disaster, such as a storm or battle. DR employs policies, tools, and procedures with a focus on IT systems supporting critical business functions. This involves keeping all essential aspects of a business functioning despite significant disruptive events; it can therefore be considered a subset of business continuity (BC). DR assumes that the primary site is not immediately recoverable and restores data and services to a secondary site. IT service continuity IT service continuity (ITSC) is a subset of BCP, which relies on the metrics (frequently used as key risk indicators) of recovery point/time objectives. It encompasses IT disaster recovery planning and the wider IT resilience planning. It also incorporates IT infrastructure and services related to communications, such as telephony and data communi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
24x7
In commerce and industry, 24/7 or 24-7 service (usually pronounced "twenty-four seven") is service that is available at any time and usually, every day. An alternate orthography for the numerical part includes 24×7 (usually pronounced "twenty-four by seven"). The numerals stand for "24 hours a day, 7 days a week". Less commonly used, 24/7/52 (adding "52 weeks") and 24/7/365 service (adding "365 days") make it clear that service is available every day of the year. Synonyms include around-the-clock service (with/without hyphens) and all day every day, especially in British English, and nonstop service, but the latter can also refer to other things, such as public transport services which go between two stations without stopping. The ''Oxford English Dictionary'' (OED) defines the term as "twenty-four hours a day, seven days a week; constantly". It lists its first reference to 24/7 to be from a 1983 story in the US magazine ''Sports Illustrated'' in which Louisiana State Universi ...

Computer Printer
A printer is a peripheral machine which makes a durable representation of graphics or text, usually on paper. While most output is human-readable, bar code printers are an example of an expanded use for printers. Different types of printers include 3D printers, inkjet printers, laser printers, and thermal printers. History The first computer printer designed was a mechanically driven apparatus by Charles Babbage for his difference engine in the 19th century; however, his mechanical printer design was not built until 2000. He also had plans for a curve plotter, which would have been the first computer graphics printer if it was built. The first patented printing mechanism for applying a marking medium to a recording medium or more particularly an electrostatic inking apparatus and a method for electrostatically depositing ink on controlled areas of a receiving medium, was in 1962 by C. R. Winston, Teletype Corporation, using continuous inkjet printing. The ink was a red sta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Computer Media
In mass communication, digital media is any communication media that operates in conjunction with various encoded machine-readable data formats. can be created, viewed, distributed, modified, listened to, and preserved on a digital electronic device, including digital data storage media (in contrast to analog electronic media) and digital broadcasting. ''Digital'' is defined as any data represented by a series of digits, and ''media'' refers to methods of broadcasting or communicating this information. Together, ''digital media'' refers to mediums of digitized information broadcast through a screen and/or a speaker. This also includes text, audio, video, and graphics that are transmitted over the internet for viewing or listening to on the internet. Digital media platforms, such as YouTube, Kick, and Twitch, accounted for viewership rates of 27.9 billion hours in 2020. A contributing factor to its part in what is commonly referred to as ''the digital revolution'' can be attribut ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Object Storage Device
Object storage (also known as object-based storage or blob storage) is a computer data storage approach that manages data as "blobs" or "objects", as opposed to other storage architectures like file systems, which manage data as a file hierarchy, and block storage, which manages data as blocks within sectors and tracks. Each object is typically associated with a variable amount of metadata, and a globally unique identifier. Object storage can be implemented at multiple levels, including the device level (object-storage device), the system level, and the interface level. In each case, object storage seeks to enable capabilities not addressed by other storage architectures, like interfaces that are directly programmable by the application, a namespace that can span multiple instances of physical hardware, and data-management functions like data replication and data distribution at object-level granularity. Object storage systems allow retention of massive amounts of unstructured data ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Self-management (computer Science)
Self-management is the process by which computer systems manage their own operation without human intervention. Self-management technologies are expected to pervade the next generation of network management systems. The growing complexity of modern networked computer systems is a limiting factor in their expansion. The increasing heterogeneity of corporate computer systems, the inclusion of mobile computing devices, and the combination of different networking technologies like WLAN, cellular phone networks, and mobile ad hoc networks make the conventional, manual management difficult, time-consuming, and error-prone. More recently, self-management has been suggested as a solution to increasing complexity in cloud computing. An industrial initiative towards realizing self-management is the Autonomic Computing Initiative (ACI) started by IBM in 2001. The ACI defines the following four functional areas: ; Self-configuration : Auto-configuration of components ; Self-healing : Automa ...
