With requests for over 100 new model S / 360-67s IBM realized there was a market for time-sharing, and agreed to develop a new time-sharing operating system called TSS / 360 ( TSS stood for Time-sharing System ) for delivery at roughly the same time as the first model S / 360-67.

** TSS / 360 ( IBM's Time-sharing System for the S / 360-67, never officially released, canceled in 1969 and again in 1971 )

Greenblatt was convinced by Ed Fredkin that time-sharing systems could be more beneficial, so he set out, along with Nelson, to write a new time-sharing system called ITS, or Incompatible Time-sharing System, initially for the PDP-6, and later the PDP-10.

* Time-sharing, known as Unix Time-sharing System ( UTS ) when abbreviated in the source code of many Unix-like operating systems

Time-sharing computers connected to modems could recognize the break because the DEL characters received had " bad parity.

Time-sharing operating systems schedule tasks for efficient use of the system and may also include accounting for cost allocation of processor time, mass storage, printing, and other resources.

* Time-sharing designs switch tasks on a regular clocked interrupt, and on events, called round robin.

Time-sharing designs switch tasks more often than strictly needed, but give smoother multitasking, giving the illusion that a process or user has sole use of a machine.

* Time Sharing Ltd. First commercial Time-sharing system in Europe and first dual ( fault tolerant ) Time-sharing system.

Time-sharing systems are multi-user systems.

Time-sharing is a method to allow fast response for interactive user applications.

Time-sharing means that many persons can access the operating system concurrently, while unaware that others are also accessing the operating system.

Time-sharing computer terminal s connected to central computers, such as the TeleVideo ASCII character mode smart terminal pictured here, were sometimes used before the advent of the PC.

In states that have been organized per the Public Land Survey System ( PLSS ), surveyors carry out BLM Cadastral Surveys in accordance with that system.

Surveys indicate that 90 % of open clusters dissolve less than 1 billion years after formation, while only a tiny fraction survive for the present age of the Solar System ( about 4. 6 billion years ).

Surveys were done using the metes and bounds method used in Virginia, rather than the Public Land Survey System established by the Land Ordinance of 1785 which was more used for the most of the Northwest Territory.

The chain starts at BMEWS ( Ballistic Missile Early Warning System ) in Thule, Greenland.

The long-range objective of this Department is to provide and maintain a system of forest development roads and trails which will adequately service the National Forest System at the levels needed to meet expected needs and optimum production of products and services.

In its prototype stage, the Atari 5200 was originally called the " Atari Video System X-Advanced Video Computer System ", and was codenamed " Pam " after a female employee at Atari Inc.

Powering the system was an Atari SALLY 6502 ( Atari's slightly custom 6502, sometimes described as a " 6502C ") processor running at 1. 79 MHz, similar to the processor found in home computers ( Atari 8-bit, Apple II, Commodore 64 ) and other consoles ( Atari 5200 and Nintendo Entertainment System ).

While the 320 pixel modes theoretically enable the 7800 to create games at higher resolution than the 256 pixel wide graphics found in the Nintendo Entertainment System and Sega Master System, the intense processing demands of MARIA typically meant that programmers created their games using the lower 160 pixel modes.

Atari Corp. then showed the Lynx to the press at the Summer 1989 CES as the " Portable Color Entertainment System ", which was changed to Lynx when actual consoles were distributed to resellers.

Auerbach discusses his work at Burroughs 1949 – 1957 managing development for the SAGE project, BEAM I computer, the Intercontinental Ballistic Missile System, a magnetic core encryption communications system, and Atlas missile.

The remaining 14 naturally occurring elements possess half lives too short for them to have been present at the beginning of the Solar System, and are therefore considered to be transient elements.

Two other satellites made observations at the time of the impact: the Ulysses spacecraft, primarily designed for solar observations, was pointed towards Jupiter from its location 2. 6 AU away, and the distant Voyager 2 probe, some 44 AU from Jupiter and on its way out of the Solar System following its encounter with Neptune in 1989, was programmed to look for radio emission in the 1 – 390 kHz range.

This follows the Incident Command System ( ICS ) principle of Span of control until the ideal distribution is achieved: one or more teams are formed at each neighborhood within a community.

; Virtual Execution System ( VES ): The VES loads and executes CLI-compatible programs, using the metadata to combine separately generated pieces of code at runtime.

The System II featured detachable controllers and had two holders at the back to wind the cable around and to store the controller in.

This re-designed System II was completed by Nick Talesfore at Fairchild.

Engelbart recruited a research team in his new Augmentation Research Center ( ARC, the lab he founded at SRI ), and became the driving force behind the design and development of the oN-Line System ( NLS ).

However, with only authoritative name servers operating, every DNS query must start with recursive queries at the root zone of the Domain Name System and each user system must implement resolver software capable of recursive operation.

Faculty members have been at the forefront of such major academic developments as the Dartmouth Conferences, the Dartmouth Time Sharing System, Dartmouth BASIC, and Dartmouth ALGOL 30.

Mature versions of the Commodore, SWTPC, Atari and Apple home computer systems all featured a disk operating system ( actually called ' DOS ' in the case of the Commodore 64 ( CBM DOS ), Atari 800 ( Atari DOS ), and Apple II machines ( Apple DOS )), as did ( at the other end of the hardware spectrum, and much earlier ) IBM's System / 360, 370 and ( later ) 390 series of mainframes ( e. g., DOS / 360: Disk Operating System / 360 and DOS / VSE: Disk Operating System / Virtual Storage Extended ).
