Do networks that connect computers eliminate theneed for wires between the computers?

If you are talking about a home network for example, sure! You can have many computers in your house all connected without wires and it would work just fine. But when the Internet becomes involved, things aren't as simple.

The Internet is a massive 'world wide web' of networks, enabling all types of devices plugged in to the Internet to communicate with one another. The network is interconnected with wires, radio waves, satellites, IR, fiber optics, etc. Theoretically, you could have an Internet based solely on wireless technologies, but it would not be as secure or as stable or most importantly, as fast as a wired Internet. The Internet carries massive amounts of information being sent continuously by all computers and devices connected to it all over the world! Because of the amount of bandwidth being used, you must use wires because it is the fastest means of sending data. Without physical wires linking computers together, the Internet would be a very inefficient way of transferring massive amounts of data to the far reaches of the globe.

In my computer center ip is assigned automatically by dhcp . But some time IP is not set to my PC .I will come 168.254.1.1?

It's hard to speculate about the problem, but DHCP has three methods how IP might be assigned to he machine. Manual (You set which machine which IP has), Dynamic (When you machine asks for IP and it gets from free IP pool and it can ask every time the same IP, extend it's usage. In this case you might loose your IP and you will get different one.) and Automatic (DHCP sets IP to machine permanently, it uses MAC-IP relation. Changing the MAC, might change your IP).

I was told yesterday that Wikipedia is more reliable than Encyclopedia Britannica. How does that make sense Why should I trust a publication that anyone can just edit or change?

Wiki is faster, so it's more reliable regarding things that are prone to fast changes.

Wiki probably have a decent piece on the upheaval in Egypt now already for instance. EB might be more reliable for things that stay the way they are.

What are high-speed memory locations built directly into the CPU which hold data while it is being processed?

There are 2 types of high-speed memory built into a CPU:

Registers - these are the fastest (and also the smallest) memory sets, they usually contain a single instruction, set of characters, an integer etc.

Cache - this is the biggest memory bank (usually up 4-8 megabytes on modern consumer CPUs) on a CPU, and will usually hold data values from the RAM that are most frequently accessed or are required for the current or upcoming computation being performed

Is the modem built into the tower?

Most computers these days - have a modem 'card' plugged into a vacant slot on the motherboard. This is the same whether it's a desktop machine or a tower unit.

How is a CPU's performance measured 2 ways?

A CPU's performance usually is determined by its clock speed (separated into two values: a multiplier, and a base clock), number of cores, and what most average people don't take into account, is instructions per clock cycle.

A base clock is the base unit of speed that the clock runs at. Typically it's at 100MHz. This value is multiplied by the multiplier to get the total clock speed (A CPU running at a clock speed of 3.4GHz will have a multiplier of 34 [34*100 = 3400MHz = 3.4GHz])

Is weather map computer generated?

Yes. Weather forecasts are calculated by supercomputers that are all over the world, in weather research centers and in certain universities.
