On the motherboard, there are two chips-the northbridge and the southbridge.Įven while there may be some disagreement as to what the computer’s heart is, comparing it to the northbridge makes the most sense: What is the brain of the computer? The heart in the human body is in charge of maintaining blood pressure and pumping blood throughout the body.Įven while there may be some disagreement about the computer’s heart, comparing it to the northbridge makes the most sense. We, therefore, cannot process information without the RAM and the CPU, respectively. Most of us associate the word “brain” with the processing carried out by our brains, thus in that sense, the computers attached to the RAM serve as the metaphorical “brain.” But the computer has limited storage capacity. Both the permanent storage device (hard drive, SD card, etc.) and the RAM can store data, but neither one can process it. The human brain, for instance, processes information and stores memories. Some say RAM is the brain of the computer while others say the operating system is the brain of the computer: What is the brain of the computer?Īlthough the analogy will depend on your definition of brain. It processes information using RAM for the incoming data and the final output. The hardware in a computing device called “Random Access Memory” (No, we are not talking about your favorite Daft Punk album) stores the operating system (OS), application programs, and data that are currently in use so that the processor of the device can access them rapidly. But from our perspective, they are wrong. Some say RAM is the computer’s brain, while others say the operating system is the computer’s brain. The history of data processing technology Three new Intel microprocessors with 14, 16, and 18 cores each were released in 2017. The 4004 used more than 2,000 transistors and 640 bytes of memory to accomplish around 60,000 operations per second. The first microprocessor, the Intel 4004, was released by Intel in 1971. In the early 1970s, Intel introduced the first computers with central processing units. CPUs must process many of the millions of running computer instructions in milliseconds: What is the brain of the computer? The history of CPUs
