Most anti-virus software and intrusion detection systems ( IDS ) attempt to locate malicious code by searching through computer files and data packets sent over a computer network.

Most strong ciphers have the desirable property of making the payload appear indistinguishable from uniformly-distributed noise, which can make detection efforts more difficult, and save the steganographic encoding technique the trouble of having to distribute the signal energy evenly ( but see above concerning errors emulating the native noise of the carrier ).

Most cheats simply will get a detection, but cheats that interfere with PunkBuster's software could get a global GUID ban.

Most modern mine bodies or casings are made of plastic material to avoid easy detection.

Most sequencing approaches use an in vitro cloning step to amplify individual DNA molecules, because their molecular detection methods are not sensitive enough for single molecule sequencing.

Most of all, case officers train agents in methods of avoiding detection by host nation counter-intelligence organizations.

Robert Barnard: " Most of the stories in this collection are ' jolly ', rather than detection.

Most upgrades to USTs consisted of the installation of corrosion control ( cathodic protection ), overfill protection ( to prevent overfills of the tank during tank filling operations ), spill containment ( to catch spills when filling ), and leak detection for both the tank and piping.

Most modern analyzers use non-dispersive infrared ( NDIR ) for detection of the carbon dioxide.

Most existing approaches to this problem have been tailored toward DoS attack detection.

Most modern leak detection systems developed around the use of a water sensitive cable which can be laid in long lengths and complex patterns around the base of the floor ; around the perimeter of rooms ; as a " barrier " over which water has to flow ; following, tracing or attached directly to lines of water pipes.

Most school systems today maintain a system of cumulative records of pupils.

Most of the analog systems also suffer from generation loss.

Most familiar systems cannot achieve negative temperatures because adding energy always increases their entropy.

Most legal cases in adversarial systems do not go to trial ; this can lead to great injustice when the defendant has an unskilled or overworked attorney, which is likely to be the case when the defendant is poor.

Most systems of classification have included this order, although sometimes under the name Capparales ( the name chosen depending on which is thought to have priority ).

Most early BBSes operated as individual systems.

Most current genome annotation systems work similarly, but the programs available for analysis of genomic DNA, such as the GeneMark program trained and used to find protein-coding genes in Haemophilus influenzae, are constantly changing and improving.

Most conjugative plasmids have systems ensuring that the recipient cell does not already contain a similar element.

Most legal systems require sufficient notice to be given to all directors of these meetings, and that a quorum must be present before any business may be conducted.

In addition, the cities of Brno, Liberec, Most, Olomouc, Ostrava, Plzeň, and Prague have tram systems.

Most of the Lisp systems whose designs contributed to Common Lisp — such as ZetaLisp and Franz Lisp — used dynamically scoped variables in their interpreters and lexically scoped variables in their compilers.

Most commuter ( or suburban ) trains are built to main line rail standards, differing from light rail or rapid transit ( metro rail ) systems by:

Most modern systems combine both solutions, where appropriate.

Most systems may be assumed to have a second order and single variable system response in the time domain ignoring multi-variable.

Most computer systems provide utility programs to assist in the back-up process, which can become very time-consuming if there are many files to safeguard.

Most cable systems are required by their franchise agreement to offer some channels, including local broadcast stations, educational, and community access channels ( PEG ), for a low rate ; this is called " Basic Cable ".

Most systems use hybrid fiber coaxial ( HFC ) distribution ; this means the trunklines that carry the signal from the headend to local neighborhoods are optical fiber to provide greater bandwidth and also extra capacity for future expansion.

Most systems were purchased with two peripherals, the Type 30 vector graphics display, and a Soroban Engineering modified IBM Model B Electric typewriter that was used as a printer.
