Advantages of computers

Comparing the computer and the brain has been instructive to both computer engineers and neuroscientists.

Computers are faster with basic operations, at a speed of 10 billion operations per second, while the brain can perform at about a thousand basic operations per second.
The computer has considerable advantages in the precision of basic operations. A 32-bit computer has a precision of 1 in 4,2 billion, while the brain has a precision of 1 in 100 at best.

Serial and parallel processing

The brain is not slow nor imprecise in performing calculations.

The human brain vs. the computer

When we contemplate which has more problem-solving power, the brain or the computer, we might think that the modern computer would come out on top. Indeed, computers have been built and programmed to beat human masters in complex games, such as chess.

Improving computer design

Over the years, engineers have taken inspiration from the brain to improve computer design.

Signaling mode

In the signaling mode of their elementary units, the computer and the brain have similarities and differences. The transistor in a computer employs digital signaling, which uses zeros and ones to represent information. The brain uses digital as well as analog signaling

Parallel processing

The brain takes advantage of the large number of neurons (100 billion neurons) and the large number of connections each neuron makes. (100 trillion synapses)
