Re: Are they tracking and profiling you?
The motherboard (main circuit board) contains the main “processing circuits” (i.e., CPU (Central Processing Unit), Processor (Pentium Processor), etc.) & it also contains some “hard memory” (i.e., RAM (Random Access Memory)) next to the processor (such as we have “short term memory”), & so that the processor can perform both calculations &/or move data around in what is also called a “scratch pad memory” – one of the main actual functions of the RAM. However, most of the information that is not immediately needed by the processor to function, such as computer programs, program data, pictures, & computer (data) files, etc., are stored in what is called “secondary storage” (i.e., hard-drives, thumb-drives, floppy drives, & even tape-drives). Secondary storage is usually slower & cheaper than RAM. So, you can have just 1 computer, even your home computer, that can access via the Internet a huge “data bank” (i.e. data-farms) that stores information about not just people, but anything you can imagine.
Now the bandwidth is a measure of how much information (in bits per second) your Internet connection can handle per unit of time. If you link into this page,
Internet Frog

It will measure the bandwidth of your Internet connection. For example, my cable modem measures about 4.4 Mbps (Mega Bits per Second or 4,400,000 bits per second) download (from the ISP’s server) to the computer, & 805 kbps (kilo bits per second or 805,000 bits per second, or 0.805 Mbps) upload (from the computer to the ISP – Internet Service Provider).
