Nowadays the CPU's could have more than one core - they may have 2, 4 cores. Of course there still are CPUs with one core and they are called single core processors.
The Intel Atom is available in both single core and dual-core varieties.The following Atom processors are single-core processors:230D410N270N280N450N470Z500Z510Z515Z520Z530Z540Z550The following Atom processors are dual-core processors:330D510

Intel Core
All intel processors Pentium 4 and down were single-core, or "core solo" processors. They weren't called "Core Solo," but by what respective family they came from. Pentium I, II, III, and 4.
Pentium 4 is an older single core processer. The Intel core 2 is a newer generation with 2 processing cores, much faster at handling multiple tasks at once. If you have a choice pick the core 2.

The Intel Core Duo.
Intel dual core
The rough equivalent would be the Intel Atom CPU, a low-power, low-performance single-core microprocessor used in netbooks and supermicro PC's.
The current lineup of Core processors includes the latest Intel Core i7, Intel Core i5, and Intel Core i3
Apple uses a range of processors depending upon their needs these include Intel Core 2 Duo, quad-core Intel Core i5, quad-core Intel Core i7, Quad-Core Intel Xeon 3500,, Quad-Core Intel Xeon 5500 "Nehalem" processors.
