The Computer and the Brain by John von NeumannPicked this up to read with a friend who said they were reading it so Im still waiting for them to finish it. I think it was really cool reading for understanding the advent of computer architecture and where it was at this point and seeing computers compared to the brain. This book combined all the things Im really interested in lately and what Id love to see would be an updated look at the ideas approached in the book. Like computers have gotten way smaller and faster and able to hold much more memory than at the time this was written so would it be fair to still make the argument that the brain computationally is more powerful? Also I thought it was interesting to think about the memory capacities and the different ways in which memory may be stored in the brain. I think the role of the Hippocampus was realized a little later, like the 70s, but it does help encode/consolidate memories and it was just interesting to see some parallels there with the stored memory in computers. Also really want to know more about the math specially the differential analyzer and the difference in the ways we understand/do math and the other possibilities which was kind of brushed upon at the end.
How Computers Work: CPU, Memory, Input & Output

Throughout history, people have compared the brain to different inventions. In the past, the brain has been said to be like a water clock and a telephone switchboard. These days, the favorite invention that the brain is compared to is a computer. Some people use this comparison to say that the computer is better than the brain; some people say that the comparison shows that the brain is better than the computer. Perhaps, it is best to say that the brain is better at doing some jobs and the computer is better at doing other jobs. This list describes only some of the similarities and differences between the computer and the brain. Can you think of any more?
Barnes Subscribe to Pewdiepie. The correct answer to this question is A, CPU. Standing for central processing unit, the CPU is the most important part of the computer , for it is where the calculations take place. There are two components of the CPU. The first is the arithmetic logic unit. This component is where arithmetic and logical operations are performed. The second component is the control unit.
The base of operations for the brains of a computer is the motherboard. The motherboard serves as a literal foundation for many of the other elements inside your computer. It's a large printed circuit board. The motherboard provides the connections and sockets that let other components communicate with each other. Motherboards come in different shapes and sizes -- a motherboard in a laptop computer might not look like one from a desktop PC. The computer brain is a microprocessor called the central processing unit CPU. The CPU is a chip containing millions of tiny transistors.

Have you ever looked inside a computer case , or seen pictures of the inside of one? The small parts may look complicated, but the inside of a computer case isn't really all that mysterious.
A region of the human brain that scientists believe is critical to human intellectual abilities surprisingly functions much like a digital computer, according to psychology Professor Randall O'Reilly of the University of Colorado at Boulder. In a review of biological computer models of the brain appearing in the Oct. Digital computers operate by turning electrical signals into binary "on and off states" and flexibly manipulating these states by using switches. O'Reilly found the same operating principles in the brain. The brain as a whole operates more like a social network than a digital computer, with neurons communicating to allow learning and the creation of memory, according to O'Reilly. However, the computer-like features of the prefrontal cortex broaden the social networks, helping the brain become more flexible in processing novel and symbolic information, O'Reilly said. The prefrontal cortex is the executive center of the brain and supports "higher level" cognition, including decision making and problem solving.
