Some virtual communities explicitly refer to the concept of cyberspace, for example Linden Lab calling their customers " Residents " of Second Life, while all such communities can be positioned " in cyberspace " for explanatory and comparative purposes ( as did Sterling in The Hacker Crackdown, followed by many journalists ), integrating the metaphor into a wider cyber-culture.

Some researchers have explored the benefits of enabling virtual communities to self-organize and introduce incentives for resource sharing and cooperation, arguing that the social aspect missing from today's P2P systems should be seen both as a goal and a means for self-organized virtual communities to be built and fostered.

Some virtual cards offer PIN < nowiki > less </ nowiki > Dialing, either by dialling a number unique to the customer, or by recognising the telephone number which originated the call by Caller ID and relating it to the appropriate account.

Some virtual machines emulate hardware that only exists as a detailed specification.

Some systems, such as the Burroughs B5500, use segmentation instead of paging, dividing virtual address spaces into variable-length segments.

Some analyses using the semiclassical approach to incorporating quantum effects into general relativity indicate that a feedback loop of virtual particles would circulate through the wormhole with ever-increasing intensity, destroying it before any information could be passed through it, in keeping with the chronology protection conjecture.

Some Transport Layer protocols, for example TCP, but not UDP, support virtual circuits provide connection oriented communication over an underlying packet oriented datagram network. Where it assures the delivery of packets in the order in which they were sent and assure that they are free of errors. The datagram transportation deliver the packets randomly and broadcast it to multiple nodes.

Some of this software ( 3D Topicscape ) works independently from virtual worlds and simply uses 3D to support user " in concept creation, planning, organization, development and actualization ".

Some virtual machines that support bytecode for Smalltalk, the Java virtual machine, and Microsoft's Common Language Runtime virtual machine as their ISA implement it by translating the bytecode for commonly used code paths into native machine code, and executing less-frequently-used code paths by interpretation ; Transmeta implemented the x86 instruction set atop VLIW processors in the same fashion.

Some exotic instruction sets do not have an opcode field ( such as Transport Triggered Architectures ( TTA ) or the Forth virtual machine ), only operand ( s ).

Some people who are in an online relationship also participate in cybersex, which is a virtual sex encounter in which two or more people who are connected remotely via computer network send each other sexually explicit messages describing a sexual experience.

Some APAs are still active as hardcopy publications, and some are published as virtual " e-zines ," distributed on the internet.

Some offer access thfough packet switched networks, or packet radio connections.

Some networks used QWK doors, and others such as RelayNet ( RIME ) and WWIVnet used non-Fido software and standards.

Some networks support DTM since 2007.

Some of the aspects of Library 2. 0 include, commenting, tagging, bookmarking, discussions, use of online social networks by libraries, plug-ins, and widgets.

Some of the most important television networks are the LBC, Murr TV, Al Jadeed, Future TV, Orange TV ( OTV ), Al-Manar, NBN, Télé Lumière, and TL ( controlled by the government ).

Some examples of pure P2P Application Layer networks designed for peer-to-peer file sharing are gnutella ( pre v0. 4 ) and Freenet.

Some networks and channels such as Napster, OpenNAP and IRC serving channels use a client – server structure for some tasks ( e. g., searching ) and a P2P structure for others.

Some proposals have been made about building a metro networks in some of the other largest cities in the country, such as one in Cluj-Napoca, and in Brașov.

Some council-member states proposed an additional protocol to the Council of Europe Cybercrime Convention, addressing materials and " acts of racist or xenophobic nature committed through computer networks "; it was negotiated from late 2001 to early 2002, and, on 7 November 2002, the Council of Europe Committee of Ministers adopted the protocol's final text titled Additional Protocol to the Convention on Cyber-crime, Concerning the Criminalisation of Acts of a Racist and Xenophobic Nature Committed through Computer Systems, (" Protocol ").

Some political scientists thus prefer to speak of policy networks and decentralized governance in modern societies rather than of state bureaucracies and direct state control over policy.

Some automated reasoners exploit the graph-theoretic features of the networks during processing.

Some local farming communities that were not connected to the main networks set up barbed wire telephone lines that exploited the existing system of field fences to transmit the signal.

Some television networks are aimed at ethnic minorities, including Spanish language networks Univisión and Telemundo.

Some examples of usage include cellular phones which are part of everyday wireless networks, allowing easy personal communications.

Some Fox stations have a newscast schedule similar to many affiliates of either of the three networks that predate the launch of Fox, along with the added 10 p. m. late newscast, a weekday morning newscast extended by two to three hours and an early evening newscast that is extended by a half-hour ( newscasts in the latter two timeslots generally compete with the national morning and evening newscasts on the Big Three networks ), while others only have a half-hour or hour-long 10 p. m. newscast.

Some larger networks utilize public peering as a way to aggregate a large number of " smaller peers ", or as a location for conducting low-cost " trial peering " without the expense of provisioning private peering on a temporary basis, while other larger networks are not willing to participate at public exchanges at all.

Some set up networks such as " intranets " for companies.
