For some reason known only to this oldie, I had a look at the writing on the three cables I own.

What does it all mean, has any of the info relevance to performance,use and quality experience?

Details:

E321220 PV AWM 2835 24AWG 60C 30V TIA/EIA 5688.2 UTP CAT5E RAPID CONN

E2444650 PV AWM 2835 60C 30V 24AWG 4PAIR  FT4ETL CAT5E UTP TIA/EIA 568-B-2 RAPID COMM

TYPE CM 24AWG 75C [UL] E186630 CSA  LL18295 FT4 ETL VERIFIED TIA/EIA-568-B.2 PATCH CABLE UTP

SOME of the abbreviations are

24 AWG - American wire guage - size 24 (see wiki for a converison chart to mm wire diameter)
basically the conductor size

CSA - Canadian standards approval - the cable complies with some section of this National standard.

UL - Underwriters laboratories approval originally a regional US approval organisation - now in worldwide usage as an approval standard to be met and it covers a wide range of things.
(used to give me much grief many years ago in getting non USA manufactured elec' subcomponents UL approved before they could be used on items for USA destinations)

TIA/EIA - Its some telecommunications cabling/quality/layout practices whatever standard - don't know details

60C - maximum rated temperature
30V - maximum rated voltage
UTP - unshielded twisted pair(s)
CAT5E - category 5 extended
4PAIR - eight wires in total, arranged in pairs (twisted)
TIA - the US Telecommunications Industry Association
EIA - the US Electronic Industries Alliance (originally Association)

UTP...are there also shielded Ethernet cables, or is there perhaps no use benefit?
4PAIR: is that a benefit over the other cables which do not mention in specs; or perhaps marketing blurb?
Temperature rating...60degC seems quite hot so assume 70 is not usually  needed?

Thanks all for info but is anyone of those cables better than the others?

Shielded cables have their uses, as do 2-pair.

I have quite a few short 2-pair cables that came with routers, only good for 100mbps.
And my lengthy LAN cable (runs a fair way round the house) from router to PVR (for iPlayer) is only 2-pair running at 100mbps - it's actually CW1308 phone cable.

Can you expand a little?

I'm trying to lose weight so you'll need to be specific and have good reason...  8)

I thought I might get similar come-back after I posted!

I meant on

Shielded cables have their uses, as do 2-pair.

As to physical expansion, I d aren't look to see, what eating on a Orkney and Shetland tour has done to me. SWMBO will be working on it!

[HPsauce]

Still not sure what you mean. 

Shielded cables have their uses in electrically-noisy environments.
2-pair are thinner and more flexible, but limited to 100mbps.

That's it really.
