Intel Core i7 is a name that the company Intel uses for the computer processors it makes for desktop and laptop computers. Intel uses this name for the fastest processors that they think will be used to build computers for consumers instead of business people. Intel started to use this name in 2008. Before 2008, Intel used the name "Core 2" for this kind of processor.
There are different types of Core i7 processor. The name does not name a type. Instead, it is the name for all of the fast processors that Intel thinks should be sold to consumers. Intel uses two other "Core i-" names for its processors for consumers: "Core i5" and "Core i3." The "Core i5" processors are mostly as fast as i7 processors, but lack the Hyper Threading technology, which create a virtual processor core, for every physical core. Intel uses the "Core i3" name for processors that only have 2 physical cores, unlike the i5 and i7 which have 4. "Core i3" can do most simple things for most people.
Intel uses a different name, Xeon, for processors that Intel makes for "server" computers for businesses. Some of the "Core i7" processors are almost the same as some of the "Xeon" processors, but each of the Xeon processors is a little bit different than the "Core i7" processor, because a "server" computer is not the same as a consumer computer. Intel also makes other "Xeon" processors that are not the same as any "Core i7" processor. Unlike the Core i7, Xeon processors support ECC (error corrected) memory, and multiple CPUs on the same motherboard.
