Network Card
What the difference between network card and broadband modem?
Why I must go through modem to connect to the internet?
Can I connect to internet just by network card?
If modem is like a converter, then what about network card? Does the network card need to convert digital signal to analog before send the data down to the cable? When the other end of the cable is connect to the modem, what happen there? Again another signal convertion by modem?
Broadband Modem: Like you say is a converter which converts the signal. A broadband modem will convert your cable service signal into digital, where as a DSL will use your phone lines.
Signal conversion happens at the modem but not network card.
Network Card: Now your computer needs to talk to this converted signal, and the interface is network card. No, network card does not convert the signal. Just like you need a monitor to display, network card is a communication device for your computer for the high-speed internet.
Yes, you can connect to the internet using network card, assuming your home/office has set up the connections and you have rj-45 drops at the location.
A typical setup for a home/medium office would be
Cable ->>Cable Modem ->>Router ->> Computer/Computers
Now if you have the RJ-45 wiring already done, then it would be:
Router ->> Switch and then you can plug in the computer in any room with a jack.
Hope this helps.
