What are the advantages of UPS - Uninterruptible Power Supply?

Answer

The primary advantage to a UPS is that in cases of sudden power loss the UPS will continue to power the computer system long enough for you to save your work.

Additionally, in environments which have problems with "dirty power"... meaning the electrical supply may have sudden spikes or dips such as in an older building or neighborhood the UPS offers a great deal more protection than a standard surge suppressor would.

In a new technology of UPS system the manufacturers offer lots of features including the surge suppression built-in device, hot-swap power module and battery module replacements. Additional backup time and run time calculation during power failure has great advantage for the end users to know the approximate time left for them to save their data before it completely shuts down (if the absence of utility power is too long and beyond the capacity of the UPS to operate).

A programmer usually tells a computer what to do through a series of instructions. A programmer designs a program that instructs the computer to follow back-to-back commands.

Now, if you mean what component of the computer is responsible for displaying what you need, then it would be the CPU (microprocessor), which is the brains and "calculator" of a computer system.

DHCP servers are found in home routers, gateways, modems, or corporate servers. However, If there is no DHCP server that is reachable, you will get an APIPA. APIPA is a range of IP address just for Microsoft operating systems. An APIPA ranges from 169.254.0.1 through 169.254.255.254. When it is activated, it constantly looks for a DHCP server to get a configuration from. When it finds a proper configuration, APIPA is disabled.

What was the problem using valves in computers?

The main problem with valves is their reliability. A secondary problem is the sheer size. Not only are transistors far more reliable, they are very much smaller by several orders of magnitude. To get some idea of the scale, the valve equivalent of a 32 GB iPhone would be bigger than the average family house and would, therefore, be anything but portable.

Max speed of coax?

Coax cable is OK for R.F. up to several gigahertz, over medium to short runs.

For data, we went to twisted-pair with 100 megabit Ethernet, and twisted-pair is now used in 10 gigabit Ethernet.

So... using Nyquist, you can probably use coax cable up to gigabit speeds over medium-short distances, but I'm not aware of anyone doing it.

Maybe try a google search.
