A status bar is a graphical control element which poses an information area typically found at the window's bottom.It can be divided into sections to group information. Its job is primarily to display information about the current state of its window, although some status bars have extra functionality. For example, many web browsers have clickable sections that pop up a display of security or privacy information.
A status bar can also be text-based, primarily in console-based applications, in which case it is usually the last row in an 80x25 text mode configuration, leaving the top 24 rows for application data. Usually the status bar (called a status line in this context) displays the current state of the application, as well as helpful keyboard shortcuts. One example is the 'vi' text editor of UNIX (from the 1970s) or newer Linux systems.
Status lines have been used for more than 30 yearsto display advisory messages in a predefined area, rather than as pop-up messages in center screen which can block the view of related information.
Sometimes, a video game places the player's vital information or Heads-up display (such as hit points, lives, and score) on a similar strip across the top or bottom of the screen; this is also referred to as a status bar.
Status bars, and status lines before them, have been used for yearsto display advisory messages in a predefined area, predating dialog boxes which can block the view of related information behind the pop-up messages. The use of status bars (or status lines) involves both advantages and disadvantages:

The graphical user interface is a form of user interface that allows users to interact with electronic devices through graphical icons and audio indicator such as primary notation, instead of text-based user interfaces, typed command labels or text navigation. GUIs were introduced in reaction to the perceived steep learning curve of command-line interfaces (CLIs), which require commands to be typed on a computer keyboard.
AppleScript is a scripting language created by Apple Inc. that facilitates automated control over scriptable Mac applications. First introduced in System 7, it is currently included in all versions of macOS as part of a package of system automation tools. The term "AppleScript" may refer to the language itself, to an individual script written in the language, or, informally, to the macOS Open Scripting Architecture that underlies the language.
Object Linking & Embedding (OLE) is a proprietary technology developed by Microsoft that allows embedding and linking to documents and other objects. For developers, it brought OLE Control Extension (OCX), a way to develop and use custom user interface elements. On a technical level, an OLE object is any object that implements the
IOleObject interface, possibly along with a wide range of other interfaces, depending on the object's needs.
In computing, Interactive System Productivity Facility (ISPF) is a software product for many historic IBM mainframe operating systems and currently the z/OS and z/VM operating systems that run on IBM mainframes. It includes a screen editor, the user interface of which was emulated by some microcomputer editors sold commercially starting in the late 1980s, including SPF/PC.
Newline is a control character or sequence of control characters in a character encoding specification that is used to signify the end of a line of text and the start of a new one. Some text editors set this special character when pressing the ↵ Enter key.
In computing and telecommunications, a menu is a list of options or commands presented to the user of a computer or communications system. A menu may either be a system's entire user interface, or only part of a more complex one.
A taskbar is an element of a graphical user interface which has various purposes. It typically shows which programs are currently running.
In computing, text-based user interfaces (TUI), is a retronym describing a type of user interface (UI) common as an early form of human–computer interaction, before the advent of graphical user interfaces (GUIs). Like GUIs, they may use the entire screen area and accept mouse and other inputs. They may also use color and often structure the display using special graphical characters such as ┌ and ╣, referred to in Unicode as the "box drawing" set. The modern context of use is usually a terminal emulator.
A graphical widget in a graphical user interface is an element of interaction, such as a button or a scroll bar. Controls are software components that a computer user interacts with through direct manipulation to read or edit information about an application. User interface libraries such as Windows Presentation Foundation, GTK, and Cocoa, contain a collection of controls and the logic to render these.
wxBasic is a free software / open-source software, cross-platform BASIC interpreter. As it is based on syntax of the BASIC language, it is designed to be simple to learn and understand, and allow novice programmers to write applications for graphical environments like Windows and Linux with minimal effort. wxBasic is a bytecode based language, like Perl or Java. It is licensed under the LGPL, so proprietary software's source code can be linked against it.
less is a terminal pager program on Unix, Windows, and Unix-like systems used to view the contents of a text file one screen at a time. It is similar to more, but has the extended capability of allowing both forward and backward navigation through the file. Unlike most Unix text editors/viewers, less does not need to read the entire file before starting, resulting in faster load times with large files.
A menu bar is a graphical control element which contains drop-down menus.
Windows Aero is a design language introduced in the Windows Vista operating system. The changes made in the Aero interface affected many elements of the Windows interface, including the incorporation of a new look, along with changes in interface guidelines reflecting appearance, layout, and the phrasing and tone of instructions and other text in applications.
An error message is information displayed when an unforeseen problem occurs, usually on a computer or other device. On modern operating systems with graphical, error messages are often displayed using dialog boxes. Error messages are used when user intervention is required, to indicate that a desired operation has failed, or to relay important warnings. Error messages are seen widely throughout computing, and are part of every operating system or computer hardware device. Proper design of error messages is an important topic in usability and other fields of human–computer interaction.
A command-line interface (CLI) processes commands to a computer program in the form of lines of text. The program which handles the interface is called a command-line interpreter or command-line processor. Operating systems implement a command-line interface in a shell for interactive access to operating system functions or services. Such access was primarily provided to users by computer terminals starting in the mid-1960s, and continued to be used throughout the 1970s and 1980s on VAX/VMS, Unix systems and personal computer systems including DOS, CP/M and Apple DOS.
Windows 10 introduced a number of new elements, including the option to use a touch-optimized interface or a traditional desktop interface similar to that of Windows 7 along with live tiles from Windows 8. However, unlike previous versions of Windows, where most, if not all, major features for that release were completed by its RTM, Windows 10 continues to receive major features and changes beyond its initial release to market. Microsoft describes Windows 10 as an 'operating system as a service' that will receive ongoing updates to its features and functionality. This is supplemented with the ability for enterprise environments to receive non-critical updates at a slower pace, and to use long-term support milestones that will only receive critical updates, such as security patches, over their ten-year lifespan of support.
In computing, a split screen is a display technique in computer graphics that consists of dividing graphics and/or text into adjacent parts, typically as two or four rectangular areas. While simple horizontal split or vertical split resembles a presentation technique used in movies and on television here it is not merely done in order to allow the simultaneous presentation of (usually) related graphical and textual information on a computer display.
