Many offer the option of viewing a work in progress on a built-in web browser.

Many web browsers now have some support for rendering SVG data but full implementations of the standard are still comparatively rare.

Many generic web servers also support server-side scripting using Active Server Pages ( ASP ), PHP, or other scripting languages.

Many web surfers regard these advertisements as highly annoying because they distract from a web page's actual content or waste bandwidth.

Many journals are electronically available in formats readable on screen via web browsers, as well as in portable document format PDF, suitable for printing and storing on a local desktop or laptop computer.

Many common network services are provided such as NTP, SNMP, web server ( Apache ), mail server ( Postfix and Cyrus ), LDAP ( OpenLDAP ), AFP, and print server.

Many web authors learn how to write client-side scripts partly by examining the source code for other authors ' scripts.

Many vendors now marry TLS's encryption and authentication capabilities with authorization.

Many different aspects of human physiology, chemistry or behavior can be used for biometric authentication.

Many cryptographic solutions involve two-way authentication, where both the user and the system must each convince the other that they know the shared secret ( the password ), without this secret ever being transmitted in the clear over the communication channel, where eavesdroppers might be lurking.

Many of Steam Guard's features will work the same with the only real difference being the method of authentication.

* Many vendors allow discovered MAC addresses to be authenticated against an authentication, authorization and accounting ( AAA ) server and subsequently filtered.

Many companies have systems, particularly in R & D, which work more or less well, depending upon size and actual belief in the policy on the part of administration, as will be abundantly apparent in subsequent quotations.

Many of the suggested systems seem to have only the most tenuous relationship to the language structures that they purport to represent.

Many school systems now employ school psychologists and child guidance specialists.

Many religions, whether they believe in the soul's existence in another world like Christianity, Islam and many pagan belief systems, or in reincarnation like many forms of Hinduism and Buddhism, believe that one's status in the afterlife is a reward or punishment for their conduct during life.

Many cultures have attached importance to astronomical events, and the Indians, Chinese, and Mayans developed elaborate systems for predicting terrestrial events from celestial observations.

Many stories have developed since the founding long ago to become a part of America's folklore and cultural awareness, and non-native American folklore especially includes any narrative which has contributed to the shaping of American values and belief systems.

Many diseases are transmitted by poorly functioning sewage systems.

Many systems became quite sophisticated in graphic presentation, especially considering that the system was confined to ASCII codes.

Many civilizations and societies have devised a calendar, usually derived from other calendars on which they model their systems, suited to their particular needs.

Many ciphers are based on publicly known algorithms or are open source, and so it is only the difficulty of obtaining the key that determines security of the system, provided that there is no analytic attack ( i. e., a ' structural weakness ' in the algorithms or protocols used ), and assuming that the key is not otherwise available ( such as via theft, extortion, or compromise of computer systems ).

Many worms that have been created are designed only to spread, and don't attempt to change the systems they pass through.

Many systems for generating musical scores actually existed well before the time of computers.

Many ( but not all ) computer systems use extensions in file names to help identify what they contain, also known as the file type.

Many modern computer systems provide methods for protecting files against accidental and deliberate damage.

Many systems have unintentionally resulted in the first possibility.

Many religious and mythological systems contain myths about a paradise.

Many systems of collation are based on numerical order or alphabetical order, or extensions and combinations thereof.

Many large cable systems have upgraded or are upgrading their equipment to allow for bi-directional signals, thus allowing for greater upload speed and always-on convenience, though these upgrades are expensive.

Many other coordinate systems have been developed since Descartes, such as the polar coordinates for the plane, and the spherical and cylindrical coordinates for three-dimensional space.

Many operating systems use name resolution logic that allows the administrator to configure selection priorities for available name resolution methods.

Many small-format digital SLR camera systems allow using many of the same lenses on both full-frame and “ cropped format ” cameras.

Many of the people involved with INGRES became convinced of the future commercial success of such systems, and formed their own companies to commercialize the work but with an SQL interface.

Many results in classical thermodynamics are not easily applied to non-equilibrium systems.

Many patented their systems such as Dee Dee Chandler of New Orleans 1904-05.

Many of the concepts in dynamical systems can be extended to infinite-dimensional manifolds — those that are locally Banach spaces — in which case the differential equations are partial differential equations.
