Operating System

Single-Core this most basic type of processor features a control unit and an arithmetic logic unit (ALU). The control unit performs operations and executes instructions while the ALU carries out mathematics calculations. A single core processor also contains cache, which is a small amount of fast memory built directly into the processor. The cache is not typically considered part of the processing core.

* A single-core processor can perform operations very quickly, but can only perform one operation at a time.

Dual-Core has the components of two separate processor cores located on the same chip. So, one dual-core CPU contains two complete processing cores which can perform two simultaneous operations. Dual-core processors may share some cache memory between the two cores or they may have independent cache memories.

Quad Core a single chip with four distinct processors, that works simultaneously.

Difference The main difference between a single-core, dual-core, and quad-core processor is the number of cores available to each processor. A quad-core processor is very fast when compared with a single-core processor, mainly because of its multiple cores. However, single-core processors are still widely used because most users do not need any additional speed to run most applications on their computers. Single cores have one core, Dual cores have two cores, and Quad cores have four. All the cores are on the same chip they share the same memory and data path to the motherboard. A Dual core processor is basically 2 processors in 1, with some loss. A Quad core is 2 Dual core processors in 1, so a Quad core would be twice as fast as a Dual core, while a Dual core is twice as fast as a single core.

The materials that comprise a processor;

Silicon, dopants. Plastic case, tin/lead leads.

Modern processors and computer components use silicone. Older processors such as the 80486 and Pentium used ceramic on the original chips, and switched to silicone.
