False
True
Multiple processor systems allow you to run multiple programs at the same time. Generally this means a system-wide boost in performance (when compared to a single CPU machine). This is especially true when you have one program that takes a lot of CPU time and would normally bog down your whole system. On a dual core machine, you have a whole other processor free to run your other, less intense, programs.
A P4 processor is fast, but the Pentium D is much faster. The D stands for Dual Core. This means that they have two on die processor cores instead of just one, as the Pentium 4 does. Two processors also makes it better for "demanding" applications. The Pentium D is better if you have a motherboard that will utilize the technology. As stated the Pentium D is Duel core. This is Intel's way of creating the closest environment of a true duel processor. The HT is for Hyper-Threading which acts like a zipper and allows several applications to process at the same time. The Pentium D will really make a difference when used with the new 64 bit operating system. However, HT (Hyper-threading) P4, does have emulated Dual Core processing. In short, the processor makes the computer think its runing a dual core. The Pentium 4 also has a couple different levels, so if you are trying to make a comparison, make sure that you look carefully. Although neither can match the power of an Athalon or an AMD x2 processor. If you are buying, get something with 64 bit processing. WAY faster and better for games and high graphic systems.
Processor speed is one of those tricky things that's really hard to grasp. Most retailers and computer junkies will refer to a processor's speed by the processor's clock speed (in Hertz, Hz). This is usually an indicator on how fast the processor will work. Unfortunately, that's not always true. For example, a single-core 2.16 GHz processor will not perform near as well as a dual-core 2 GHz processor. In general, newer processors that have many cores will throw clock speed ratings out the window. (For a more accurate definition of speed, try to find out how many "flops", or calculations per second, a processor can do. This is more commonly seen on supercomputers.) Assuming that these are both single-core processors, a clock speed of 2.16 GHz would be faster than a clock speed of 2 GHz. If either of these are multi-core, however, it's probably better to go with more cores.
true
Not necessarily. In the 8085, for instance, this is true. In the 8088, however, the processor is a 16 bit processor with an 8 bit data bus. The same is true for the 80386sx - it is a 32 bit processor on a 16 bit bus.
No.
No it is not true. It is a scam
True.
no it is not true. there is solid iron and nickel in the Earths core
