What is an rss reader used for? for creating a user account on a social new site

RSS which stands for Really Simple Syndication or Rich Site Summary is a way to have information easily delivered to you instead of making an effort to go look for it. With so much information and new content on the web popping up daily, it can be difficult to keep up. With an RSS feed, you will automatically stay informed by retrieving the latest content from sites you have an interest in and this will save you time.

given the options, i would say your best bet is c. the modem supports up to 56 kbps, which is too low for video streaming. dial up modems use actual phone lines, which only can go up to 56 kbps as that's more than sufficient for traditional phone calls. this is also the reason why when a dial-up modem connects, you hear all those sounds. it's literally using the phone line to establish a connection.

this seems to be in the wrong category. but i'll take some free points my dude

posting this in wrong category will result in people seeing it who won't know the answer.
