ADSL is a type of broadband connection. Do you get your internet service through a cable provider or a phone provider? If it's a phone provider, you have some type of DSL.
yes you can
Speed, mainly. Broadband (cable internet) is going to be much faster than DSL.
A wireless router provides a wireless network, but does not provide Internet connectivity by itself, unless it is a combination router/modem, such as a Motorola Surfboard. A typical home wireless router will not have this functionality included, so a cable modem is often required to access a cable provider's Internet service. Buying a device that includes both wireless routing and cable modem features will allow the network to access the Internet without a dedicated cable modem, while all others will require a cable modem separately. In either case, a device that provides the features of a cable modem is required for cable Internet.
Moderm modems (Dial-up, Cable, ADSL) are connected directly to the Ethernet port of the computer.
