In this day and age, people tend to buy trendy electronic devices with exciting features and requirements to help fulfill their different needs. This successively helped producers come up with an idea that would not only help make the processor powerful but would also guarantee electronic gadgets to have an extended battery life, better speed, graphics, and software, and the ultimate idea was to increase the cores. 
Difference between dual core processor and Quad Core processor

 Multi-core processors help individuals manage multiple programs or applications by splitting the load between multiple processors and help make the laptop quicker and stronger to carry out intensive tasks.

Dual-Core vs Quad-Core

The difference between Dual-Core and Quad-Core is that dual-core has two core processors and are useful for individuals who require energy-efficient and cost-effective computers for basic multitasking and day-to-day activities like going through their email or surfing the internet whereas quad-core has four core processors and are useful for individuals who require faster speed and can manage numerous tasks simultaneously.

What is Dual Core?

A dual-core processor is a central processing unit with 2 processors. Each processor has its own set of controllers which enables the dual-core to work more efficiently and effectively than a single-core processor. Since there are two processors they can perform functions all the more swiftly. A few examples of dual-core technologies would be the AMD X2, Intel core duo, etc.

Some of the advantages of dual-core are that dual-core processors perform better than single-core processors. Dual-core processors have the benefit of dividing the data for processing by several units. When one has to run more than one process at a time the performance boost is very helpful.

What is Quad Core?

The quad-core processor is a central processing unit with 4 processors. Since there are multiple cores, chip manufacturers can initiate a better performance without having to boost the clock speed. This permits the operating system to divide the processing load between many processors so that the work is done all the more swiftly. Some examples of quad-core processors would be AMD Phenom X4, Intel Core 2 Quad, etc.
