Evolution of Processors
The x86 architecture is one of the most widely used processor architectures in the world today. It was developed by Intel Corporation in the late 1970s and was first used in their 8086 microprocessor. This architecture has undergone significant changes and improvements over the years from its early versions to its modern versions. In this lesson, we will explore the rise of Intel and the x86 architecture.
In the early days of computing, processors were generally simple and slow, but Intel changed the game when they introduced the 4004 microprocessor in 1971. This was the first commercially available microprocessor and it paved the way for the development of more advanced processors. Over the years, Intel continued to improve their processors and in 1978 they introduced the x86 architecture with the 8086 microprocessor.
The x86 architecture quickly became popular and was used in many different types of computers. One of the main reasons for its success was its compatibility with previous versions of the architecture. This meant that software written for older processors could still be used on newer processors without any problems. This made it easier for software developers to create programs that could run on a wide range of computers.
Intel continued to improve the x86 architecture with the release of the 80286, 80386, and 80486 processors. These processors were faster and more powerful than their predecessors, and they helped to usher in the era of personal computers. In the early 1990s, Intel released the Pentium processor, which was even more powerful than the previous versions. This processor was used in many popular computers including the original IBM PC.
Today, the x86 architecture is still widely used in desktop and laptop computers, as well as servers and other devices. Intel continues to improve the architecture with the release of new processors such as the Core i3, i5, and i7. These processors offer even more power and speed than previous versions, and they are used in many different applications including gaming, video editing, and scientific computing.
