I know this may sound dumb, but i need answers and am qurious so (Oh and I can't spell) I recently got my bro a pentium 4 2.80Mhz and my sis comp came with a Celeron D 3.06Mhz (The same one I had till I went back and got an AMD) But plz explain the difference and in a Pentium 4 2.80Mhz and a Celeron D 3.06 Which is better.

Firstly, I think you mean 'GHz', not 'MHz'. 3MHz would be extremely slow in today's terms :) The difference between Pentiums and Celerons is basically that the Pentium has more processor cache. In simple terms, cache is RAM for processors. Frequently-used instructions are stored in the cache so that the processor does not need to fetch them from the main memory, a much slower process. Generally, Celerons have 256Kb of Level 2 cache and Pentium 4s have 1-2Mb. This will make a difference in processor-intensive tasks such as graphical gaming or rendering images (for example, using Photoshop or movie editing). The Celeron is the cheap option compared to the Pentium, and is intended for users who only do the occasional gaming or rendering, and more of the word processing and Windows applications. Dispite the Celeron being faster in your case, you'll probably still find that the Pentium outperforms the Celeron in almost everything.

Also the core on the P4 is faster than the one on the Celeron. That P4 will own the Celeron big time.

Are there 3GHz Celerons? I don't think I have ever seen one.

I think whenever Intel release a Pentium, they dumb down the cache and process to make a Celeron. Not sure though, it may be a different, cheaper design, but that's what I've heard. I've never seen a 3GHz Celeron, but I don't keep up with them.

Well, Celerons use the same core design as the Pentiums from their era, for example the Pentium II Deschultes core was "dumbed down" to make a Celeron Deschultes. Same with the PIII Coppermine, and now with the P4 Northwood - I think they use the cores from Pentium chips that didn't make the grade (basically that failed Intel's speed tests) and then match them up with some low-end cache, and bob's your uncle. A Celeron is born.
