Some spectrum analyzers, such as real-time spectrum analyzers, use a hybrid technique where the incoming signal is first down-converted to a lower frequency using superheterodyne techniques and then analyzed using fast fourier transformation ( FFT ) techniques.

Some microcontrollers have a real-time clock built in, generally only the ones with many other features and peripherals.

Some of the benefits he receives from wearing a computer include being able to type and access the Internet while walking around or talking to others allowing him to take notes on a conversation in real-time, opening up notes on a certain subject and e-mailing them at any time or even having two conversations at once, one online and one face to face, and if he comes across something he doesn't know or recognize, he can instantly find out.

Some operators use USSD to provide access to real-time updates from social-networking websites like Facebook and Twitter.

Some commentators think that " Strategy is irrelevant in today ’ s real-time strategy games when you ’ re playing against a fourteen-year-old who can click twice as fast as you.

Some online stores have real-time chat features, but most rely on e-mail or phone calls to handle customer questions.

* Some system calls ( mostly hardware-related: e. g. real-time clock ) and parts of the / proc and / sys filesystems are left unvirtualized.

Some ECN brokers may offer additional features to subscribers such as negotiation, reserve size, and pegging, and may have access to the entire ECN book ( as opposed to the " top of the book ") that real-time market data regarding depth of trading interest.

Some of Tiberian Suns advertised features, such as intelligent and adaptive skirmish AI, unit veterancy, and real-time lighting were severely scaled back as the result of time constraints.

Some annotation engines are online, including the ALIPR. com real-time tagging engine developed by Pennsylvania State University researchers, and Behold-an image search engine that indexes over 1 million Flickr images using automatically generated tags.

Some methods use the server only when establishing the connection, while others are based on relaying all data through it, which adds bandwidth costs and increases latency, detrimental to real-time voice and video communications.

Some grids may use pricing mechanisms that are not real-time, but easier to implement ( users pay higher prices during the day and lower prices at night, for example ) to provide some of the benefits of the demand response mechanism with less demanding technological requirements.

Some, like VirtualBox and VMware Player run on Windows and Linux hosts and can run many other operating systems.

Some disk operating systems were the operating system for the entire computer system.

Some operating systems for mobile phones and mobile devices use ELF:

Some constitutions or fundamental laws provide for a head of state who is not only in theory but in practice chief executive, operating separately from, and independent from, the legislature.

( Note: Some older operating systems may handle such values incorrectly ( i. e., signed instead of unsigned ), which would make it impossible to access files larger than 2 GB in size.

Some historians argue that it had ceased to exist by 1791 ; others that it was still operating as late as 1813.

Some Christians favor political and administrative decentralization of the government, with separate Muslim and Christian sectors operating within the framework of a confederation.

Some 500, 000 motorcycles were estimated to be operating in Mali in 2009, with two thirds of them inexpensive Chinese made cycles, known locally as " Jakarta " s, which boast better fuel economy but fewer safety features than more expensive Japanese or Western brands.

Some mask revisions of the 68LC040 contained a bug that prevents the chip from operating correctly when a software FPU emulator is used.

Some train operating companies continue to use the former British Rail Rail Alphabet lettering to varying degrees in station signage, although its use is no longer universal ; however it remains compulsory ( under Railway Group Standards ) for safety signage in trackside areas and is still common ( although not universal ) on rolling stock.

Some problems were classic subjects of comparison with other operating systems:

Some printers have IrDA receivers, allowing IrDA-equipped PDAs to print to them, if the PDA's operating system supports it.

( Some legacy operating systems, including early versions of Unix and Windows, limited passwords to an 8 character maximum, reducing security.

Some of the uses in the new series include: repairing electronic equipment ; re-attaching materials such as barbed wire ; detecting, intercepting and sending signals ; remotely operating the TARDIS ; burning, cutting, or igniting substances ; fusing metal ; scanning and identifying substances ; amplifying or augmenting sound ; modifying mobile phones to enable " universal roaming ”; disabling alien disguises ; resonating concrete ; reversing teleportation of another entity.

Some trains had power, but the signals did not, requiring special operating procedures to ensure safety.

Some editors, such as WordStar, have dual operating modes allowing them to be either a text editor or a word processor.

Some text editors provide a way to insert the output of a command issued to the operating system's shell.

Some installations use Linux for zSeries to run Web servers, where Linux runs as the operating system within many virtual machines.

Some operating systems can control Wake-on-LAN behaviour via hardware drivers.

Some groundcrew are linked to specific airlines operating at the airport.

Some machines, like the Atari ST microcomputer, were " instant-on ", with the operating system executing from a ROM.

Some operating systems are supplied in both server and desktop versions with similar user interface.

Some scammers are part of less organized gangs or are operating independently ; such scammers have reduced access to the above connections, and thus have little success with wealthier investors or business entities attempting to research them, but are still convincing to middle-class individuals and small businesses, and can bilk hundreds of thousands of dollars from such victims.

Some operating systems such as early versions of Unix did not support attaching debuggers to running processes, so core dumps were necessary to run a debugger on a process's memory contents.
