Vertical Cabling - Runs between floor to floor. It is used for Core to Distribution (or Access) switch connectivity. Usually consists of fiber cables
Horizontal Cabling - Runs on one floor. Runs from Distribution or Access switches to the end user. Usually copper.
CAT5 or if nessecary CAT6 Twisted pair...
Three commonly followed standards for constructing and installing cabling include the Telecommunications Industry Association (TIA) standards, specifically TIA/EIA-568 for commercial building cabling, the National Electrical Code (NEC) for electrical safety, and the Institute of Electrical and Electronics Engineers (IEEE) standards, such as IEEE 802.3 for Ethernet networking. These standards ensure proper performance, safety, and interoperability of cabling systems. Adhering to these guidelines helps prevent issues like signal interference and ensures compliance with local regulations.
The mass must be greater than the mass of the elevator including the maximum amount of cabling that it has, plus the carrying capacity plus a safety margin.
That depends on the power factor.The best the power factor can get is ' 1 ', if the load is all resistive with no reactance.In that case, 100 VA = 100 watts.If there's effective capacitance or inductance in the load or the cabling, then the V and the Awon't be exactly in phase, the power factor will be less than 1, and the 100VA will produceless than 100 watts.The 'power factor' is the cosine of the angle between 'V' and 'A' on the line. So"wattage" is (100) x cosine(angle between V and A).

Horizontal cabling is the cabling that connects the work area telecommunications room to the horizontal cross connect.

im going to assume your talking about computer networking which in this case would be RISER. In ceiling would be plenum
what is different between cross cabling and straight cabling ANSWER: a crossover cable is used to connect like devices, like a router to a router, but a straight through cable is used to connect dissimilar devices, like a router to a computer.
None of the above
