features? Well, the "features" of a true standard 56k modem are that it accepts and sends information in bits and packages through a phone line. DSL and Cable modems are different. They actually convert data back and forth for a higher stream range. I suggest you goto howstuffworks.com. They have an extensive area for modems and networking materials.
The computer hardware is the part which we can touch.
One who want to connect to the internet.
no
I hope the answer must have already been clear. But still, let me give you a proper conclusion. DSL modem can have two types, SDSL and ADSL. Though, most of the times when we use the word DSL, we generally refer to the ADSL modem, but in certain cases, it can even be the SDSL modem. Hence, this is the difference. An ADSL modem can send and receive data at different speeds while SDSL modem can send data at only one speed.
if your modem has wireless capblility then you don't need a router.
You should be able to buy an external 56K USB modem at any place that sells computer parts. The modem just plugs in to a USB port, and the phone line plugs into the modem.
Because you use different modes to access it!
Yes you can because the modem router has a modem built in. There are different types of modem routers that suit different needs. If you are only going to be surfing the web you will need a "N" modem router, if you are going to be sharing files then you will need a "N+" modem router and if you are going to be gaming e.g. connecting to a Xbox 360 or PlayStaion 3 you will need a "N+N" modem router, I would personally recommend Belkin modem routers. Hope you find this useful!
External parts of the computer include the monitor and the modem or tower. Other external parts are the mouse, keyboard, and speakers.
Since this was posted under Cable Modems, I'm assuming that you are asking about the (Data Over Cable Service Interface Specification (DOCSIS) cable modem which allows different cable companies and different cable modem manufactures all to adhere to a uniform set of protocols and modulation schemes to allow for inter and intra market competition. Go to Wikipedia and search DOCSIS for more information if that truly was your question.
They can be a great deal of different. The speed of the connection depends on, among other things, the modem being used. Generally the modem in a 'phone is not as fast as the modem connection in a PC
No, a router connects 2 or more different networks. A modem just changes the signal type.

There are currently no adapters to change the gender of a modem. This is due to the way the different modems process the different types of data.
Cable,phone,satellite.
A router and a modem are two separate things. There are a few different modem/router combo's, but typically you will need both items.
