There are many, one would be low-cost provider. As with all such "advantages" as your competitors play "catch-up" they become commodities or entry-level requirements. \n\nTechnology leads are a good one, look at how all the mobile phoe operators are trying to get into premium services and move from box shifting (the actual phone)

The upside down v is an identification marker used by a number of militaries to distinguish their vehicles from enemy vehicles.  The upside-down v is actually the chevron symbol.\n\nThese markers were first used by the Israelis in the Arab-Israeli War (1967) to prevent casualties from friendly fire.

Call Centers are being downsized and outsourced to foreign countries where the wages are lower. Also IVR's (Interactive Voice Response) systems are eliminating a lot of jobs by automating much of the data handling and distribution to the customer. The IVR is the system that you hear when you call a company and the phone system says "Press 1 for Department X" . . .etc."

There are cell towers positioned all ocer the world: how many bars you have is how in tune you are to the cell phone tower. Your signal jumps from tower to tower just like a land line, but wireless. Your phone-number is a code for which thing to respond. How it finds it, that i dont know.

It's a string that has a metal weight on one end (a plumb bob). It is hung by the other end, and the weight pulls it down so it makes a vertical reference line. It's used in construction to see that walls and objects are vertical.

There is no difference.  Analog (voice) calls are digitized (sampled and quantized) the first time they hit a telco switch, usually within three miles of origin.  Everything through the network is digital.  They are converted back to analog at the local switch at the destination end -- again, within a few miles of the destination.\n\nFor transmission, calls are transmitted in 64k channels.  These are "stacked" on each other using time division mulitiplexing (TDM)and frequency division multiplexing (FDM).  T1, T3, and SONET are all built up through TDM and FDM to get the high-speed aggregate rates for long haul communications.

Vertical integration refers to the structure of the business operation meaning that the company controls all manufacturing aspects of its particular product.  A good example would be a vertically integrated oil company like Exxon Mobil that does everything from explore for oil, drill for it, ship it, refine it and sell it.  The company controls every aspect of the supply chain from getting the oil out of the ground and into your gas tank.  If you're asking about a "utility" as in the utility bills you pay, then I would guess that the phone company is the best example.  Verizon, for example, builds the network by putting wires into the ground and into your house and then it operates the network and charges you for it.

A vertical market refers to all players involved in the production of a good or service from raw materials to the end user.  For example, Paper starts with loggers, goes to paper mills, then is packaged and sold by various companies (such as HP).  As far as segment goes, it could be any one part or portions of this supply chain.
