why does  cable internet need a modem if modems are for transforming analog signals...isnt cable digital?

The signals on the cable are many frequencies, and they have mixed a lot of types of data all on one cable.  The modem extracts a digital data stream which connects to the provider's server.  The modem then gives 10BaseT ethernet data to your computer.  That conversion must happen in the modem, since the cable has regular TV channels and other stuff mixed in.

No. Need analog modem for phone line

dsl  is an ethernet connection. to upgrade it, you can call your dsl company and ask for more bandwidth., or switching to  the cable company  POSSIBLY could be faster, depending on how many other people on your block are using it.\n the difference between ethernet and usb is which plug you stick the cord into your computer. i would get the ethernet modem, that way it will be much easier to add a router later on if you want to. a router lets you plug more than one computer up to your dsl connection. b y the way 512kbps is pretty fast in my opinion. it's more than fast enough to stream video.

Coaxial cable.. is used by the broadband land lines...\n\nBut in essence, a signal can travel with all  circuits.\n\n\nexample ( phone companies that have broadband on their phones move the signal via Microwave and fiber optic networks).\n\nDSL at home usess Coaxial

By cable.......and you need cables.

I have an analogue and digital phone and also run a wireless network. The signal to the modem and the phones is analogue over copper wire. It would be very rare for a broadcast signal (digital cordless phone) to effect cable. You must ensure however that all the required ADSL filters are in place and they usually come with the modem. These are primarily to filter the ADSL signal from the phones and the analogue telephone signal from the ADSL Modem.\n\nPS: Cable broadband similar but I was assuming you were refering to DSL.\n\nCheers

ok, here, i'll explain, in much better etail than the other 2 answers. \nA dial-up modem is really nothing more than a telephone. only, it is programed to interpret certain sounds/electrical signals that come from the telephone as somthing that your computer can understand. because of this, it does act as a telephone call, thus, you cannont make any calls on that line. \n\na DSL modem is basically the same thing, believe it or not. it still uses your phone line, but, it uses a different frequency to transfer information. it uses a higher frequency of the phone line, like the fast and slow lanes of a highway. but, the major difference between the dial-up modem and the DSL one right now is that the DSL modem has to be configured to recieve these high frequency messages.\n\na Cable modem is completely different from both dial-up and DSL modems. a cable modem uses a different wire, instead of a telephone wire, it uses a digital coaxle wire. this wire supports more data transfer at a time than phone wires do, thus, you may get higher speeds of interent.\n\nnow, there is one last thing that is usually overlooked. as you probably know, you have 1+ telephone wire per a house. and this wire, never joins with other wires. thus, it is alwayse only you on your phone, nodoby else. because of this, DSL's speed of internet remains relativly the same throught the day. However, the coaxle cable that you have for a cable modem joins togeather with everyone in your community, so, if more people are on the internet in your community, then your connection will be slower. so, at different times during the day, your connection may be slightly faster of slower, depending on how many other people in your community are on the internet.

When the modem is first making the connection it is sending digital signals which are being translated into audible noises.  The higher pitched sound is one digit, the lower sound is a zero.  The computer at the other end receives the audio signal, and converts them back to digital signal.\n\nHence the word MODEM - it MOdulates and DEModulates

DSL is through your phone company which will require that you have a phone line hooked up to the modem  If you don't want to pay for a phone in your house then depending on the company they can do it.  Most of the time they will require you to have a phone line make sure you put it to the most basic service there is. But the best way to go in my opionion is Cable modem if they offer it in your area.  if you live in Texas then you might be lucky and be in the area that they are testing out Internet through the powerlines.

Cable is typically 3Mbps or faster throughput, and DSL is usually limited to 1 or less. You can get business DSL and get faster speeds, but the latency on cable is much faster then DSL. The company I work for the majority of my employees use Cable and I suggest cable just because of that reason. Cable can actually reach speeds of 10Mpbs a second I beleive and DSL is pretty limited as cable companies I've heard across the US are upgrading the speed already from what its at now.

Yes u can use Modems To USB there are many modem presend U can also use a usb hub that make it big USB so Its goes more easy for u

Yes you need one for dial up.It is usually a 56 kpbs internal modem that comes with the computer.You can also get an external modem if your system dont have that

You would need to contact your cable company...They will furnish you with a cable modem.

Ya U must have cable modem for the cable connection

Yes, you can order just cable internet. You don't have to buy TV, nor   phone service to get internet from almost all cable companies.

Neither one is more secure than the other.  The security comes in how you secure your own computer using AntiVirus software, personal firewalls, Ad or Spamware, etc.  You may see a slight degradation of service using Cable in the evening when more people are home and using their cable modems.  Otherwise, the main difference will be in cost.  As for what you need to connect to your computer, both Cable and DSL will come into your home into some sort of a modem.  From there you will just need an ethernet cable (you can get these at any computer or electronics store, such as Best Buy, Radio Shack, Fry's Electronics, etc), which will plug directly into your Ethernet (NIC) card in your computer.  The plug on your computer will look like the modem plug, but will be slightly larger.  See the link below for more information on DSL and Cable.  Good luck.

If I am not mistaken, when you plug in the ethernet cable (which looks like a huge telephone wire), your computer should recognize that it is receiving information via this cable.  Your Internet Service Provider may have additional, service-specific, instructions that must be followed.  There may also be variations on these directions if you have to run your connection through both a router and a modem.  Hopefully, when your provider activated your service, all of that was done for you and then you can just "plug and play."
