When an application makes a request that requires a domain name lookup, such programs send a resolution request to the DNS resolver in the local operating system, which in turn handles the communications required.

Though attractive in many cases, a general-purpose DBMS is not always the optimal solution: When certain applications are pervasive with many operating instances, each with many users, a general-purpose DBMS may introduce unnecessary overhead and too large " footprint " ( too large amount of unnecessary, unutilized software code ).

When the 4GL was first introduced, a disparate mix of hardware and operating systems mandated custom application development support that was specific to the system in order to ensure sales.

When free and open source Unix-like operating systems such as GNU / Linux and 386BSD became available in the early 1990s many volunteer software developers abandoned MINIX in favor of these.

When Mach was first being seriously used in the 2. x versions, performance was slower than traditional monolithic operating systems, perhaps as much as 25 %.

When Mach 3 attempted to move most of the operating system into user-space, the overhead became higher still: benchmarks between Mach and Ultrix on a MIPS R3000 showed a performance hit as great as 67 % on some workloads.

When Richard Stallman and the GNU team were implementing POSIX for the GNU operating system, they objected to this on the grounds that most people think in terms of 1024 byte ( or 1 KiB ) blocks.

When the critical section is longer than a few source code lines or involves lengthy looping, an embedded / real-time algorithm must resort to using mechanisms identical or similar to those available on general-purpose operating systems, such as semaphores and OS-supervised interprocess messaging.

When the original IBM-PC was created in 1980, there were three leading competing operating systems: PC-DOS, CP / M-86, and UCSD p-System, while Xenix was added in 1983-1984.

When a reference is made to a page by the hardware, if the page table entry for the page indicates that it is not currently in real memory, the hardware raises a page fault exception, invoking the paging supervisor component of the operating system.

When the Macedonian army approaches Thracian Chersonese ( the Gallipoli Peninsula ), an Athenian general named Diopeithes ravages this district of Thrace, thus inciting Philip's rage for operating too near one of his towns in the Chersonese.

When operating away from planetary magnetospheres, a magnetic sail would force the positively charged protons of the solar wind to curve as they passed through the magnetic field.

When compared with more modern operating systems.

When the power of the latter was made both limited and explicit -- when norms were clarified and made more precise and the creation of new norms was placed exclusively in parliamentary hands -- two purposes were served: Government was made subservient to an institutionalized popular will, and law became a rational system for implementing that will, for serving conscious goals, for embodying the `` public policy ''.

When the frequency response characteristics of practical components are considered, their effect on stability does not present the most serious limit on the system loop gain.

When the system is arranged for automatic leveling, the platform angles respond to any horizontal components of acceleration acting on the accelerometers.

When the system is on automatic leveling, the gyro drift is canceled by the output of the leveling system ( amplifier Af ).

When a Java technology-enabled web browser processes a page that contains an applet, the applet's code is transferred to the client's system and executed by the browser's Java Virtual Machine ( JVM ).

When the Ming Dynasty Chinese astronomer Xu Guangqi adapted the European southern hemisphere constellations to the Chinese system in The Southern Asterisms, he combined Apus with some of the stars in Octans to form the " Exotic Bird " ( 異雀, Yìquè ).

When AppleNet was cancelled in October, Sidhu led an effort to develop a new networking system based on the AppleBus hardware.

When the Roman Empire turned Christian during the following century, this imagery came to be used in a more metaphysical sense, and removed legal impediments to the development and public use of the Anno Domini dating system, which came into general use during the reign of Charlemagne.

When gastric hydrochloric acid reaches the nerves in the gastrointestinal mucosa, they signal pain to the central nervous system.

When a cartridge was inserted into the system, the 7800 BIOS included code which would generate a digital signature of the cartridge ROM and compare it to the signature stored on the cartridge.

When in “ 7800 ” mode ( signified by the appearance of the full screen Atari logo ), the graphics are generated entirely by the MARIA graphics processing unit, all system RAM is available and game data is accessed in larger 48K blocks.

When alcohol consumption is stopped too abruptly, the person's nervous system suffers from uncontrolled synapse firing.

When the system is idle, the CPU clocks itself down via lower bus multiplier and selects a lower voltage.

When the serving side loses a rally, the serve immediately passes to their opponent ( s ) ( this differs from the old system where sometimes the serve passes to the doubles partner for what is known as a " second serve ").

When a backplane is used with a plug-in single board computer ( SBC ) or system host board ( SHB ), the combination provides the same functionality as a motherboard, providing processing power, memory, I / O and slots for plug-in cards.

When the PC starts up, the first job for the BIOS is the power-on self-test, which initializes and identifies system devices such as the CPU, RAM, video display card, keyboard and mouse, hard disk drive, optical disc drive and other hardware.

When one or more output variables of a system need to follow a certain reference over time, a controller manipulates the inputs to a system to obtain the desired effect on the output of the system.
