Throbber
A throbber, also known as a loading icon, is an animated graphical control element used to show that a computer program is performing an action in the background (such as downloading content, conducting intensive calculations or communicating with an external device). In contrast to a progress bar, a throbber does not indicate how much of the action has been completed. History An early use of a throbber occurred in the NCSA Mosaic web browser of the early 1990s, which featured an NCSA logo that animated while Mosaic downloaded a web page. As the user could still interact with the program, the pointer remained normal (and not a busy symbol, such as an hourglass); therefore, the throbber provided a visual indication that the program was performing an action. The Netscape web browser also featured a throbber. In version 1.0 of Netscape, this took the form of a big blue "N" (Netscape's logo at the time). The animation depicted the "N" expanding and contracting hence the name "thro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
NCSA Mosaic
NCSA Mosaic is a discontinued web browser. It was instrumental in popularizing the World Wide Web and the general Internet during the 1990s by integrating multimedia such as text and graphics. Although not the first web browser (preceded by WorldWideWeb, Erwise, and ViolaWWW), it was the first browser to display images inline with text instead of a separate window. It supported various Internet protocols such as HTTP, FTP, NNTP, and Gopher. Its interface, reliability, personal computer support, and simple installation contributed to Mosaic's initial popularity. Mosaic was developed at the National Center for Supercomputing Applications (NCSA) at the University of Illinois at Urbana–Champaign beginning in late 1992, released in January 1993, with official development and support until January 1997. Mosaic lost market share to Netscape Navigator in late 1994, and had only a tiny fraction of users left by 1997, when the project was discontinued. Microsoft licensed one of the ...

Windows Wait Cursor
The Windows wait cursor, informally the Blue circle of death (known as the hourglass cursor until Windows Vista) is a throbber that indicates that an application is busy performing an operation. It can be accompanied by an arrow if the operation is being performed in the background. The wait cursor can display on programs using the Windows API. History From Windows 1.0 to Windows XP, it was represented by an hourglass. Windows Vista introduced a new, animated wait cursor. The wait cursor in Windows 7 was almost identical. It is possible, however, to change the appearance of the cursor into the original hourglass cursor. Windows 8 introduced a new flat wait cursor, which is light blue on dark blue and removes the fade and the particles from the animated part. Usage There are two uses for the wait cursor: short term and long term. The wait cursor is a shared resource in the system across applications and windows. By default, when the mouse cursor is in a window, the cursor shown i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spinning Pinwheel
The spinning pinwheel is a type of progress indicator and a variation of the mouse pointer (graphical user interfaces), pointer used in Apple Inc., Apple's macOS to indicate that an application software, application is busy. Officially, the ''macOS Human Interface Guidelines'' refer to it as the spinning wait cursor, but it is also known by other names. These include, but are not limited to, the spinning beach ball, the spinning wheel of death, and the spinning beach ball of death. History A Watch, wristwatch was used as the first wait cursor in early versions of the classic Mac OS. Apple's HyperCard first popularized animated cursors, including a black-and-white spinning quartered circle resembling a beach ball. The beach-ball cursor was also adopted to indicate running script code in the HyperTalk-like AppleScript. The cursors could be advanced by repeated HyperTalk invocations of "set cursor to busy". Wait cursors are activated by applications performing lengthy operations. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pointer (computing WIMP)
In human–computer interaction, a cursor is an indicator used to show the current position on a computer monitor or other display device that will respond to input, such as a text cursor or a mouse pointer. Etymology ''Cursor'' is Latin for 'runner'. A cursor is a name given to the transparent slide engraved with a hairline used to mark a point on a slide rule. The term was then transferred to computers through analogy. On 14 November 1963, while attending a conference on computer graphics in Reno, Nevada, Douglas Engelbart of Augmentation Research Center (ARC) first expressed his thoughts to pursue his objective of developing both hardware and software computer technology to ''augment'' human intelligence by pondering how to adapt the underlying principles of the planimeter to inputting X- and Y-coordinate data, and envisioned something like the cursor of a computer mouse, mouse he initially called a ''bug'', which, in a 3-point form, could have a "drop point and 2 orthogon ...

Web Apps
A web application (or web app) is application software that is created with web technologies and runs via a web browser. Web applications emerged during the late 1990s and allowed for the server to dynamically build a response to the request, in contrast to static web pages. Web applications are commonly distributed via a web server. There are several different tier systems that web applications use to communicate between the web browsers, the client interface, and server data. Each system has its own uses as they function in different ways. However, there are many security risks that developers must be aware of during development; proper measures to protect user data are vital. Web applications are often constructed with the use of a web application framework. Single-page applications (SPAs) and progressive web apps (PWAs) are two architectural approaches to creating web applications that provide a user experience similar to native apps, including features such as smooth ...

Computer Terminal
A computer terminal is an electronic or electromechanical hardware device that can be used for entering data into, and transcribing data from, a computer or a computing system. Most early computers only had a front panel to input or display bits and had to be connected to a terminal to print or input text through a keyboard. Teleprinters were used as early-day hard-copy terminals and predated the use of a computer screen by decades. The computer would typically transmit a line of data which would be printed on paper, and accept a line of data from a keyboard over a serial or other interface. Starting in the mid-1970s with microcomputers such as the Sphere 1, Sol-20, and Apple I, display circuitry and keyboards began to be integrated into personal and workstation computer systems, with the computer handling character generation and outputting to a CRT display such as a computer monitor or, sometimes, a consumer TV, but most larger computers continued to require terminal ...

Multiuser DOS
Multiuser DOS is a real-time multi-user multi-tasking operating system for IBM PC-compatible microcomputers. An evolution of the older Concurrent CP/M-86, Concurrent DOS and Concurrent DOS 386 operating systems, it was originally developed by Digital Research and acquired and further developed by Novell in 1991. Its ancestry lies in the earlier Digital Research 8-bit operating systems CP/M and MP/M, and the 16-bit single-tasking CP/M-86 which evolved from CP/M. When Novell abandoned Multiuser DOS in 1992, the three master value-added resellers (VARs) DataPac Australasia, Concurrent Controls and Intelligent Micro Software were allowed to take over and continued independent development into Datapac Multiuser DOS and System Manager, CCI Multiuser DOS, and IMS Multiuser DOS and REAL/32. The FlexOS line, which evolved from Concurrent DOS 286 and Concurrent DOS 68K, was sold off to Integrated Systems, Inc. (ISI) in July 1994. Concurrent CP/M-86 The initial version of C ...

DR-DOS
DR-DOS is a disk operating system for IBM PC compatibles, originally developed by Gary A. Kildall's Digital Research, Inc. and derived from Concurrent PC DOS 6.0, which was an advanced successor of CP/M-86. Upon its introduction in 1988, it was the first DOS that attempted to be compatible with IBM PC DOS and MS-DOS. Its first release was version 3.31, named so that it would match MS-DOS's then-current version. DR DOS 5.0 was released in 1990 as the first to be sold in retail; it was critically acclaimed and led to DR DOS becoming the main rival to Microsoft's MS-DOS, who quickly responded with its own MS-DOS 5.0 but releasing over a year later. It introduced a graphical user interface layer called ViewMAX. DR DOS 6.0 was released in 1991; then with Novell's acquisition of Digital Research, the following version was named Novell DOS 7.0 in 1994. After another sale, to Caldera, updated versions were released partly open-source under the Caldera moniker, and briefly as ...

UNIX
Unix (, ; trademarked as UNIX) is a family of multitasking, multi-user computer operating systems that derive from the original AT&T Unix, whose development started in 1969 at the Bell Labs research center by Ken Thompson, Dennis Ritchie, and others. Initially intended for use inside the Bell System, AT&T licensed Unix to outside parties in the late 1970s, leading to a variety of both academic and commercial Unix variants from vendors including University of California, Berkeley ( BSD), Microsoft (Xenix), Sun Microsystems ( SunOS/ Solaris), HP/ HPE ( HP-UX), and IBM ( AIX). The early versions of Unix—which are retrospectively referred to as " Research Unix"—ran on computers such as the PDP-11 and VAX; Unix was commonly used on minicomputers and mainframes from the 1970s onwards. It distinguished itself from its predecessors as the first portable operating system: almost the entire operating system is written in the C programming language (in 1973), which allows U ...
