Yes. If you see a page with a facebook “like” or “share” button, they know you visited that page. And they know what that page is about so they add that to your profile.
If you are a member, they add this to your FB profile. If you are not a member, they keep an “anonymous” profile. They have many ways of getting name/email/phone/zip/etc into this “anonymous” profile. But they don’t need that use what they’ve collected for targeted content and ads on other sites you visit. Most people have visited 100s or 1000s of sites with FB buttons so they have a lot of information about them and about what they do on those sites (which pages. how long do you stay on a page, ...).
And, you only have to SEE the buttons on the page. You don’t need to click them. I did some work for a HUGE company that refused to put FB buttons on websites for this reason. I was in many technical and high level (C*O) meetings with FB to try to find a solution. FB would not budge on their being able to collect visitor data even though they REALLY wanted their buttons on 10s of millions of our page views a day. They offered things like segregating data from our sites into profiles that that wouldn’t be used for anything other than targeted ad on OUR sites.
We offered to do things like collect/store the data ourself and provide them the minimum needed if one of our brands wanted to use FB targeting for a campaign (along with a fee to them to run the targeting). Since they said they only wanted data for targeted campaigns on OUR sites, but the wouldn’t accept our housing the data and paying them almost whatever they wanted when we had a targeted campaign, it was pretty obvious they wanted the data for other reasons.
If you hit their website they know your IP. They can match that up with data from other data acquisition firms they own. If your browser is accepting cookies they scribble data to it.
Algorithms thus can be seen as simply the formal description of computer programs.
So what are they used for? For anything that you may want a computer to calculate.
From very mathematical concepts like "an algorithm that tells you whether a certain number is prime or not"
to AI systems such as "an algorithm that, based on the pages that you like at Facebook, determines which ads would be best to show you".
Once you come up with the algorithm or have read about it and understood it, then in theory you can implement it
in any programming language of your choice. (hat tip quora.com)

Facebook has been collecting and storing detailed calling and text messaging records from some of its users for years, the company admitted over the weekend. The data was collected on an opt-in basis, but the breath of information retained further adds to the privacy backlash the company is currently facing.
First reports about Facebook collecting this data surfaced last week, when some users made use of a Facebook feature that allows them to download all of their data from the company’s servers. Some users found that these records included detailed records about phone calls they made in the past, including numbers called, as well as date, time and duration of each and every call.
