Multilink dial-up provides increased bandwidth by channel bonding a number of dial-up connections and accessing them as a single data channel. It requires two or more modems, telephone lines, and dial-up accounts, in addition to an ISP that supports multilinking – and naturally any line and information expenses are additionally doubled. This inverse multiplexing possibility was briefly well-liked with some excessive-finish users earlier than ISDN, DSL and other applied sciences grew to become out there. Diamond and different vendors created special modems to assist multilinking. Operating on a single channel, a dial-up connection monopolizes the cellphone line and is one of the slowest methods of accessing the Internet.

Web-conferencing software program and Facebook also yielded probably the most constructive findings, influencing four of the seven indicators of student engagement, compared to different collaborative applied sciences, similar to blogs, wikis, and Twitter. Facebook is an online-based service that permits users to create a public or personal profile and invite others to attach. Within an educational context, Facebook has usually been used as a supplementary instructional tool to lectures or LMSs to support class discussions or develop, deliver, and share academic content and resources. The majority of research on Facebook tackle behavioral indicators of scholar engagement, with far fewer focusing on emotional or cognitive engagement. We chose to concentrate on applied sciences for which there were multiple research printed, allowing us to determine areas of convergence and divergence in the literature and draw conclusions about positive and adverse effects on scholar engagement.…
