Neste artigo será mostrado que os tipos diferentes de objeto de aprendizagem contribuem para facilitar o processo de aprendizagem do estudante. Esses  objetos podem ser compostos apenas de um elemento ou de vários recursos  digitais combinados. Podem ter a lógica e a estrutura para gerar outros objetos,  mas acima de tudo devem interagir com os alunos colaborando em sua  aprendizagem.

Providing QoS-guaranteed services in current installed networks is an important issue, but only deploying QoS services is not enough to guarantee their success: QoS management must also be provided. Nowadays, police-based network management (PBNM) addresses this need, but such management is not enough either. Network managers deal with QoS tasks that cannot be performed using only PBNM. Other solutions, besides PBNM, have to be used to proceed with QoS management-related tasks. Unfortunately, these solutions are independent from each other, leading to a scenario where integration is difficult. This paper introduces QAME (QoS-Aware Management Environment) which main goal is the provisioning of facilities to allow a common and integrated Web-based management of QoS-enabled networks.
