Safe mode is a diagnostic mode of a computer operating system (OS). It can also refer to a mode of operation by application software . Safe mode is intended to help fix most, if not all, problems within an operating system.
Some commands are internal—built into COMMAND.COM; others are external commands stored on disk. When the user types a line of text at the operating system command prompt, COMMAND.COM will parse the line and attempt to match a command name to a built-in command or to the name of an executable program file or batch file on disk.
The Multics shell includes a run command to run a command in an isolated environment. [1] The DEC TOPS-10 [2] and TOPS-20 [3] Command Processor included a RUN command for running executable programs. In the BASIC programming language, RUN is used to start program execution from direct mode, or to start an overlay program from a loader program.
It is unclear if the Rocky Mountain BASIC name was original to HP or came from outside, but HP/Keysight use the term in their own documentation, as well as the more formal "HP BASIC" product name. The HP 9830A, introduced in 1972, was the top of the 9800 line programmable calculator line, which was the first HP computer which fit on a desktop ...
It includes all commands that are standardized by the Internet Engineering Task Force (IETF) in RFC 959, plus extensions. Note that most command-line FTP clients present their own non-standard set of commands to users. For example, GET is the common user command to download a file instead of the raw command RETR.
A command-line interface (CLI) is a means of interacting with a computer program by inputting lines of text called command lines. Command-line interfaces emerged in the mid-1960s, on computer terminals, as an interactive and more user-friendly alternative to the non-interactive mode available with punched cards. [1]
PCL 5 was released on the HP LaserJet III [2] in March 1990, adding Intellifont font scaling (developed by Compugraphic, now part of Agfa), outline fonts and HP-GL/2 (vector) graphics. PCL 5e (PCL 5 enhanced) was released on the HP LaserJet 4 [ 2 ] in October 1992 and added bi-directional communication between the printer and the PC and Windows ...
In computing, Verbose mode is an option available in many computer operating systems and programming languages that provides additional details as to what the computer is doing and what drivers and software it is loading during startup or in programming it would produce detailed output for diagnostic purposes thus makes a program easier to debug.
