As redes locais virtuais, ou VLANs, devem obedecer ao padrão IEEE 802.1Q. Esse padrão estabelece o uso de etiquetas que identificam cada quadro de dados que trafega por uma rede local de computadores. Dessa forma, os quadros podem ser separados e encaminhados corretamente aos dispositivos pertencentes a uma VLAN específica. Assinale a alternativa correta a respeito do padrão IEEE 802.1Q para VLANSs.

As contratações de bens e serviços de tecnologia da informação, no âmbito dos órgãos e entidades pertencentes ao Sistema de Administração dos Recursos de Informação e Informática (SISP), foram disciplinadas pela Instrução Normativa n.º 4/2010 do Ministério do Planejamento, Orçamento e Gestão (MPOG). Essa instrução determina que as contratações de solução de tecnologia da informação deverão seguir três fases. Assinale a alternativa que apresenta essas três fases.

A computer network, often simply referred to as a network, is a collection of hardware components and computers interconnected by communication channels that allow sharing of resources and information. Where at least one process in one device is able to send/receive data to/from at least one process residing in a remote device, then the two devices are said to be in a network.

Networks may be classified according to a wide variety of characteristics such as the medium used to transport the data, communications protocol used, scale, topology, and organizational scope.

Communications protocols define the rules and data formats for exchanging information in a computer network, and provide the basis for network programming. Well-known communications protocols are Ethernet, a hardware and Link Layer standard that is ubiquitous in local area networks, and the Internet Protocol Suite, which defines a set of protocols for internetworking, i.e. for data communication between multiple networks, as well as host-to-host data transfer, and application-specific data transmission formats.

Computer networking is sometimes considered a sub-discipline of electrical engineering, telecommunications, computer science, information technology or computer engineering, since it relies upon the theoretical and practical application of these disciplines.
