Which is the best Buy: Shielded and Unshielded Ethernet Cables?

We are planning to wire for home or office with ethernet networking cables to set up internet network, Which is the suggestions and guidelines keep in mind for Ethernet networking cable.
Digital Signal Processing is the process of transmission and production of data that takes place without any interference. This process asks for an Ethernet Cable. Most of the wired networks of today including routers, PCs and switches use Ethernet cables for the smooth transmission of data. These Ethernet Cables are of two types – Shielded and Unshielded. They are also known as STP (Shielded Twisted Pair) and UTP (Unshielded Twisted Pair). The question that arises next is - which one out of the two you should buy? To find this out, make sure you know about the environment you need Ethernet cables for.

I agree with what  @sfcable states - only you know your environment.

Are you in a particularity noisy environment like an office - or a quieter space like an apartment or house?

Screened Ethernet cables are really designed to maximize transmission rates in an office or industrial space where there are hundreds of feet of cable lying side by side.

Home environments tend to be very quiet by comparison.

My house is wired with un-screened CAT6 and I have not experienced any problems with my content streaming of music or video.

Save your cash  and spend that money on more hi-fi stuff :-)

Unless you have a really noisy and crazy environment you are running the cable through UTP should be just fine. I have UTP cat5e I ran years and years ago, every once in a while I put a managed switch on the network and never found any dropped packets.
I run with a group of audio guys in Denver that don't fly the mainstream rhetoric. After some testing, it was determined that the CAT 7 & 8 extra shielding of each twisted pair induced audible and additional noise & distortion. 

I know the "expert" computer jocks will tell you this just is not possible. And I have found that some CAT 7 made for audio is quite good. As for me, I use CAT 6A. Consider that the positive respondents on this little forum mention CAT 5 & 6. Before you invest in wiring the place, I recommend you actually listen to a piece of whatever you think you plan to use against the older standards that we prefer. Cheaper per foot too. That advice to have 10 gig wire is overkill unless your looking to be ready for double HD4 video, which is twice the density of the filmmakers state of the art today; at least the last time I sat in front of a non-computer video screen of about two years ago.

Ultimately, you need to make the distinction between whether you are an audiophile or a movie buff. Audiophiles only care what it sounds like to them, and that is where I live. 

Thanks to everyone who has reply my question. and help me to select an ethernet cable for business & home.
