You need a TV device for your PC that is compatible to your cable format. If it is DVB-C, for example my cable has DVB-C, and I'm using a "Cablestart combo HD CI" device, which I can connect to the cable and that also has a CI card slot for encrypted programs. I'm using a PC running Linux that is running a program called TVheadend that acts as a media server, and then I can watch TV running on that server using Kodi which is installed on other PC's.

If your cable is still sending out analog signals, you can also get analog TV devices. With all those devices you also get software to watch TV.

Thank you so much for your fast reply. I think it needs tv card which can match my laptop and can be bought. it looks like that Cablestart combo HD CI does not match laptop.
It does work with a laptop, it is connected via USB (but I only gave it as an example). Anything that is connected via USB will wotk with laptops. But my device is a little old and may not be available anymore. But there are many other devices available. Hauppauge makes many such TV devices.

You need a TV Tuner for the computer.  Then you need software that allows you to "tune" stations.

What you get depends on what you want to watch.  IDEALLY, you can get a network based cable card tuner such as the HD Home Run Prime which allows you to get a cable card from your cable provider (doesn't work with satellite, but works with FiOS and cable television providers).  The cable card will allow you to get full HD quality and every station EXCEPT on-demand programming that you subscribe to.  I use a Ceton InfiniTV and HD Home Run Prime so I have 7 tuners and can watch and record 7 different HD programs at once using Windows Media Center (now a paid add-on to Windows 8, was FREE with Windows 7).
The product you linked to only supports analog signals from cable TV. So if your cable TV provider only has digital TV it won't work. If you live in Europe you need something that supports DVB-C (the "C" stands for cable). If your provider still has analog signals, I suggest you first check with the provider on their plans for the future. Many I know of have turned off the analog signal, or are at least planning on doing so soon. So buying an analog tuner now usually makes little sense. Also check the standard you are using. The US uses different standards than Europe or Asia, so you would have to get a tuner built for the standards in your country. Also, not all digital cable TV providers have unencrypted channels, so you may need a tuner that can take your provider's CI card so you can watch the encrypted channels you have a subscription for. For that you'd need a tuner with CI card slot. The tuner from the link below has such a slot:
