Executive Officer
An executive officer is a person who is principally responsible for leading all or part of an organization, although the exact nature of the role varies depending on the organization. In many militaries and police forces, an executive officer, or "XO", is the second-in-command, reporting to the commanding officer. The XO is typically responsible for the management of day-to-day activities, freeing the commander to concentrate on strategy and planning the unit's next move. Administrative law While there is no clear line between principal executive officers and inferior executive officers, principal officers are high-level officials in the executive branch of U.S. government such as department heads of independent agencies. In ''Humphrey's Executor v. United States'', 295 U.S. 602 (1935), the Court distinguished between executive officers and quasi-legislative or quasi-judicial officers by stating that the former serve at the pleasure of the president and may be removed at their di ...

Non-executive Director
A non-executive director (abbreviated to non-exec, NED or NXD), independent director or external director is a member of the board of directors of a corporation, such as a company, cooperative or non-government organization, but not a member of the executive management team. They are not employees of the corporation or affiliated with it in any other way and are differentiated from executive directors, who are members of the board who also serve, or previously served, as executive managers of the corporation (most often as corporate officers). However they do have the same legal duties, responsibilities and potential liabilities as their executive counterparts. Non-executive directors provide independent oversight and serve on committees concerned with sensitive issues such as the pay of the executive directors and other senior managers; they are usually paid a fee for their services but are not regarded as employees. All directors should be capable of seeing corporate and business ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Executable
In computing, executable code, an executable file, or an executable program, sometimes simply referred to as an executable or binary, causes a computer "to perform indicated tasks according to encoded instruction (computer science), instructions", as opposed to a data (computing), data file that must be interpreted (parser, parsed) by a program to be meaningful. The exact interpretation depends upon the use. "Instructions" is traditionally taken to mean machine code instructions for a physical central processing unit, CPU. In some contexts, a file containing scripting instructions (such as bytecode) may also be considered executable. Generation of executable files Executable files can be hand-coded in machine language, although it is far more convenient to develop software as source code in a high-level language that can be easily understood by humans. In some cases, source code might be specified in assembly language instead, which remains human-readable while being close ...

UNIVAC EXEC 8
OS 2200 is the operating system for the Unisys ClearPath Dorado family of mainframe systems. The operating system kernel of OS 2200 is a lineal descendant of Exec 8 for the UNIVAC 1108. Documentation and other information on current and past Unisys systems can be found on the Unisys public support website.Current Unisys documentation is available on thUnisys public support web site For OS 2200 products, select one of the ClearPath Dorado platforms (e.g., Dorado 800 or Dorado 8300) and then the release level (usually the highest numbered one unless you are looking for something specific in an earlier release). That will take you to a search page where you can search by title or document content. See Unisys 2200 Series system architecture for a description of the machine architecture and its relationship to the OS 2200 operating system. Unisys stopped producing ClearPath Dorado hardware in the early 2010s, and the operating system is now run under emulation. History There wer ...

UNIVAC 1108
The UNIVAC 1100/2200 series is a series of compatible 36-bit computer systems, beginning with the UNIVAC 1107 in 1962, initially made by Sperry Rand. The series continues to be supported today by Unisys Corporation as the ClearPath Dorado Series. The solid-state 1107 model number was in the same sequence as the earlier vacuum-tube computers, but the early computers were not compatible with the solid-state successors.

UNIVAC EXEC II
{{operating-system-stub ...
EXEC II is a discontinued operating system developed for the UNIVAC 1107 by Computer Sciences Corporation (CSC) while under contract to UNIVAC to develop the machine's COBOL compiler. They developed EXEC II because Univac's EXEC I operating system development was late. Because of this the COBOL compiler was actually designed to run under EXEC II, not EXEC I as specified in the original contract. EXEC II is a batch processing operating system that supports a single job stream with concurrent spooling.

EXEC 2
EXEC 2 is an interpreted, command procedure control, computer scripting language used by the EXEC 2 Processor originally supplied with the CMS component of the IBM Virtual Machine/System Product (VM/SP) operating system. Relation to EXEC EXEC 2 is mostly compatible with CMS EXEC but EXEC 2 scripts must begin with an &TRACE statement. Some EXEC statements and predefined variables do not exist in EXEC 2, although in some cases there are analogs. There are some minor differences in some statements and predefined functions. EXEC 2 has the following enhancements: * There is no 8-byte restriction on token length. * Statements can be up to 255 characters long. * EXEC 2 can issue commands to subcommand environments as well as CMS and CP. * EXEC 2 has additional built-in functions. * EXEC 2 has user-defined functions. * EXEC 2 commands may include subroutines and functions. * EXEC 2 has extra debugging facilities. * CMS programs can manipulate EXEC 2 variables.

Executive Producer
Executive producer (EP) is one of the top positions in the making of a commercial entertainment product. Depending on the medium, the executive producer may be concerned with management accounting or associated with legal issues (like copyrights or royalties). In films, the executive producer generally contributes to the film's budget and their involvement depends on the project, with some simply securing funds and others being involved in the filmmaking process. Motion pictures In films, executive producers may finance the film, participate in the creative effort, or work on set. Their responsibilities vary from funding or attracting investors into the movie project to legal, scripting, marketing, advisory and supervising capacities. Executive producers vary in involvement, responsibility and power. Some executive producers have hands-on control over every aspect of production, some supervise the producers of a project, while others are involved in name only. The creditin ...

CMS EXEC
CMS EXEC, or EXEC, is an interpreted, command procedure control, computer scripting language used by the CMS EXEC Processor supplied with the IBM Virtual Machine/Conversational Monitor System (VM/CMS) operating system. EXEC was written in 1966 by Stuart Madnick at MIT on the model of CTSS RUNCOM. He originally called this processor COMMAND, and it was later renamed EXEC. CMS EXEC has been superseded by EXEC 2 and REXX. All three — CMS EXEC, EXEC 2 and REXX — continue to be supported by the IBM CMS product. The EXEC language *EXEC processes lines up to 130 characters long when entered from a terminal, or 72 characters when read from a file. *A ''label'' consisting of a dash followed by up to seven alphanumeric characters can prefix a CMS command or an EXEC control statement. *The interpreter parses commands into blank-delimited '' tokens'' of up to eight characters each. *Variables consist of an ampersand followed by up to seven alphanumeric characters. Variables can ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Exec (Amiga)
Exec is the kernel of AmigaOS. It is a 13 KB multitasking microkernel which enabled pre-emptive multitasking in as little as 256 KB of memory (as supplied with the first Amiga 1000s). Exec provided functions for multitasking, memory management, and handling of interrupts and dynamic shared libraries. It acts as a scheduler for tasks running on the system, providing pre-emptive multitasking with prioritized round-robin scheduling. Exec also provides access to other libraries and high-level inter-process communication via message passing. Other comparable microkernels have had performance problems because of the need to copy messages between address spaces. Since the Amiga has only one address space, Exec message passing is quite efficient. The only fixed memory address in the Amiga software (address 4) is a pointer to exec.library, which can then be used to access other libraries. Exec was designed and implemented by Carl Sassenrath.
