A substantial increase is estimated in the cost of operating additional communications systems in the air defense program, as well as in all programs where speed and security of communications are essential.

In total, these increases in operating costs outweigh the savings that result from declining programs and from economy measures, such as reduced numbers of units and installations, smaller inventories of major equipment, and improvements in the supply and distribution systems of the Armed Forces.

The current drawn by typical constant-voltage energy distribution systems is usually dictated by the power ( watts ) consumed by the system and the operating voltage.

Harvesting is performed by divers using surface supplied air " hookah " systems operating from runabout style, outboard powered boats.

The majority of aircraft power their avionics using 14-or 28 ‑ volt DC electrical systems ; however, larger, more sophisticated aircraft ( such as airliners or military combat aircraft ) have AC systems operating at 400 Hz, 115 volts AC.

It is natively supported by most operating systems / GUIs for drawing windows ( where applicable ) or widgets:

AIX ( Advanced Interactive eXecutive, pronounced ) is a series of proprietary Unix operating systems developed and sold by IBM for several of its computer platforms.

It is one of four commercial operating systems that are presently certified to The Open Group's UNIX 03 standard.

The AIX family of operating systems debuted in 1986, became the standard operating system for the RS / 6000 series on its launch in 1990, and is still actively developed by IBM.

AIX was the first operating system to utilize journaling file systems, and IBM has continuously enhanced the software with features like processor, disk and network virtualization, dynamic hardware resource allocation ( including fractional processor units ), and reliability engineering ported from its mainframe designs.

Version 4. 1, in a slightly modified form, was also the standard operating system for the Apple Network Server systems sold by Apple Computer to complement the Macintosh line.

It is included in most Windows Server operating systems.

The first BBSes used homebrew software, quite often written or customized by the SysOps themselves, running on early S-100 microcomputer systems such as the Altair, IMSAI and Cromemco under the CP / M operating system.

By 1995, many of the DOS-based BBSes had begun switching to modern multitasking operating systems, such as OS / 2, Windows 95, and Linux.

Almost universally, home computers of the 1980s had a ROM-resident BASIC interpreter, allowing the machines to boot directly into BASIC which therefore constituted a significant and visible part of the user interface of many home computers ' rudimentary operating systems.

JPI first launched a MS-DOS compiler named JPI Modula-2, that later became TopSpeed Modula-2, and followed up with TopSpeed C, TopSpeed C ++ and TopSpeed Pascal compilers for both the MS-DOS and OS / 2 operating systems.

However, as of 2011 adoption of the new terms has been slow and usage has been limited in the marketplace and in the press, with notable exceptions such as Linux operating systems, several textbooks and scientific research papers.

* Several computer operating systems have various methods of running software originally designed for older versions or other OSs:

Their operating systems, called MCP ( Master Control Program — the name later borrowed by the screenwriters for Tron ), were programmed in ESPOL ( Executive Systems Programming Oriented Language, a minor extension of ALGOL ), and later in NEWP ( with further extensions to ALGOL ) almost a decade before Unix.

Because of this, is usually a more effective choice under these operating systems ; sensitivity for these two combinations can be enhanced by the CONFIG. SYS statement.

This is the primary function of the imagination operating in the absence of the original experiential stimulus by which the images were first appropriated.

Within a few years various Du Pont manufactured items were filling the entire requirements of from four to seven of General Motors' eight operating divisions.

Demand for parts for home entertainment was strong in the first half, but purchases were cut back to lower levels during the fall as set manufacturers reduced their own operating rates.

They were operating in 10 of the 17 major areas of chronic labor surplus and in 10 of the minor areas.

Grab samples were collected from the existing oxidation pond to determine its operating conditions.

If all the operating variables were varied simultaneously, Af operations would be required to do the same job, and as R increases this increases very much more rapidly than the number of operations required by the dynamic program.

The input and output levels and operating voltages were compatible between the different gates.

Based on the Motorola 68000 family of microprocessors, the machine sports a custom chipset with graphics and sound capabilities that were unprecedented for the price, and a pre-emptive multitasking operating system called AmigaOS.

The SCO Group, who argued they were the rightful owners of the copyrights covering the Unix operating system, attempted to revoke IBM's license to sell or distribute the AIX operating system.

A few years later, in 1981, IBM introduced the first DOS based IBM PC, and due to the overwhelming popularity of PCs and their clones, DOS soon became the operating system on which the majority of BBS programs were run.

MS-DOS continued to be the most popular operating system for BBS use up until the mid-1990s, and in the early years most multi-node BBSes were running under a DOS based multitasker such as DESQview or consisted of multiple computers connected via a LAN.

The 2nd and 7th divisions were assigned independent roles, operating in Western Thrace and eastern Macedonia respectively.

When the Apple II, PET 2001 and TRS-80 were all released in 1977, all three had BASIC as their primary programming language and operating environment.

Initially, there were 25 franchises, but the number of different operating companies is smaller as some firms, including First Group, National Express Group and Stagecoach Group, run more than one franchise.

Early implementations were for the DEC PDP-7 and PDP-11 minicomputers using early Unix, and Honeywell 36-bit mainframes running the operating system GCOS.

Both planes were operating at the very limits of their range and the slightest error or fault in the equipment could keep them from reaching the small island.

At a certain point, reports of an IRA sniper operating in the area were allegedly given to the Army command centre.

By the early 2000s, CPU designers were thwarted from achieving higher performance from ILP techniques due to the growing disparity between CPU operating frequencies and main memory operating frequencies as well as escalating CPU power dissipation owing to more esoteric ILP techniques.

By the mid-1960s, parts of Cambodia's eastern provinces were serving as bases for North Vietnamese Army and Viet Cong ( NVA / VC ) forces operating against South Vietnam, and the port of Sihanoukville was being used to supply them.

The government made three unsuccessful attempts to enter into negotiations with the insurgents, but by 1974, the CPK were operating openly as divisions, and some of the NVA combat forces had moved into South Vietnam.

Even though each 1541 had its own on board disk controller and disk operating system, it was not possible for a user to command two 1541 drives to copy a disk ( one drive reading and the other writing ) as with older dual drives like the 4040 and 8050 that were often found with the PET computer, and which the 1541 was backward compatible to ( it could read 4040 disks but not write to them since its internal Operating System was essentially the same ).

Unfortunately, however, the routines in the 1541 disk operating system to enable disk copy were removed as it was intended to be a stand-alone unit.
