Digital Subscriber Loop technologies permit high data rate transmission over existing twisted pair copper wiring in the local loop (eg home-local telephone exchange) communications infrastructure. Asymmetric DSL permits voice and digital traffic to be carried simultaneously. Broadband downstream rate typically in the range 0.5 - 8 Mbits/s. Upstream rates typically 0.1 - 2 Mbits/s.

Originally arising from the study of philosophy, an agent is an autonomous entity capable of acting out its own agenda. A software agent is defined as a self-contained program that is capable of making independent decisions. The difference between general software programs and agents can be subtle.

Student-centred learning
The model of student-centred learning is generally contrasted with teacher-centred learning and emphasises learning from the point of view of the student and student engagement. Students are not seen as empty vessels to be filled with knowledge by the experienced teacher, but as coming already equipped with their own frameworks and existing knowledge, and capable of taking responsibility for their own learning (see constructivism). There are, however, different degrees of student-centred learning appropriate in courses.
Contrasting with student-centred learning, teacher-centred learning places the teacher at the centre of the learning process, or as the expert in the subject area who transmits or conveys knowledge and understanding to students. In this model, students assume a more passive role in relation to learning.

A tumblelog is a variation of a blog, that favors short-form, mixed-media posts over the longer editorial posts frequently associated with blogging. Common post formats found on tumblelogs include links, photos, quotes, dialogues, and video. Unlike blogs, this format is frequently used to share the author's creations, discoveries, or experiences without providing a commentary. One of the many tumblelog sevices is tumblr.
