The core i7 processor, smaller and faster than the 8008

The CPU (central processing unit), microprocessor, or graphics card, is a single chip in a computer that is responsible for overseeing every action in a computer. The CPU is located on the motherboard. All systems in a computer must pass through the CPU to perform their task. When a task calls upon the CPU, the CPU pulls data from the RAM, SSD, or other pieces of hardware where said task originates. For example, the instruction to launch a program are stored in the RAM, so when the program requested to opened, the CPU pulls those instructions from the RAM and begins the process of launching the program. Once the CPU reads the data is has received, it guides the data on the system bus, which is where data travels to wherever it will execute its designated task.

The CPU handles two types of data. The first type of data that the CPU deals with is data that is in need of processing. The second type of data that the CPU deals with is program code. The program code is instructions for the CPU from the data that needs to be processed. The program code tells the CPU where the data in need of processing needs to go, and in what order on the system bus. The CPU also interrupts data in need of processing for components of a computer that don't understand data.

KL Intel C8008-1

The first CPU, the 8008 microprocessor

The first CPU was invented in 1972 by Intel. This processor, the 8008, ran at 200 kilohertz, and had 3,500 transistors. The faster the CPU runs, the faster it can process data. The more transistors the CPU has, the more data the CPU can handle at any one time. Intel, the leading developer in the CPU, continues to develop processors with higher speeds and more transistors. The developers are also trying to make smaller processors, so they can fit more in a computer. Intel made several breakthroughs in the development of the CPU. In 2001, the Pentium 4 was introduced. This processor ran at speeds of 1.5 GHz, and had 42 million transistors. In 2015, the Core i7 was introduced. This processor ran at speeds of 3.5-4.2 GHz, and had 1350 million transistors. The CPU will continue to grow in speed and ability as the modern demand for data in increasing in out tech driven world.
