A typical computer is built with the microprocessor (CPU), main memory, and other basic components all plugged into the motherboard. The CPU is the abbreviation for central processing unit.

A BRIEF COMPUTER HISTORY. The computer as we know it today had its beginning with a 19th century English mathematics professor name Charles Babbage. He designed the Analytical Engine and it was this design that the basic framework of the computers of today are based on.

There are lots of differences between modern and old computers. Modern computers have a larger memory and can run several and more complex programs at once. The size of computers has decreased by a huge amount making computers very easy to carry around.

In the late 1950’s, computers got smaller because one of its main components – the valve – was replaced by the much smaller transistor. These made computers far more reliable and therefore businesses took a much greater interest in them. But being smaller, it lead again to a decrease in the size of computers.

Modern Day Computers – The Evolution. All modern day computers are in a nutshell a collection of electronic switches. Switches are used to represent and control the routing of data in the form of binary digits or sometimes just called bits. In the early days of electronic computers they used vacuum tubes as switches.

Given that matrix solve is an N3 operation, this means that hardware and software today, as applied to the same matrix solve technique, is now over 300,000,000 times faster than in 1985.

Future computers promise to be even faster than today’s computers and smaller than a deck of cards. Perhaps they will become the size of coins and offer “smart” or artificial intelligence features like expert intelligence, neural network pattern recognition features, or natural language capabilities.

Top500: Japan’s Fugaku Still the World’s Fastest Supercomputer | Data Center Knowledge. Arm-powered Fugaku, in Kobe, Japan, is the the world’s fastest supercomputer as of November 2020, according to Top500.org.

Computers are becoming faster and faster, but their speed is still limited by the physical restrictions of an electron moving through matter.

BEST OVERALL: Dell XPS 8930 Tower Desktop It has an 8-core i7 processor that runs at 4.7GHz, 64GB of RAM, and four terabytes of storage (2TB SSD + 2TB Hard Drive). These features make XPS 8930 the most powerful desktop computer we’re recommending by a long shot.

So, if someone ever asks you, “What makes a computer fast?” it’s all of the above. You will need the best processor or CPU, cache, RAM, bus speed, Hard Drive, GPU, and the latest software and operating system. All of these aspects, working together in harmony, are what makes a computer fast.

SSDs are much faster than hard drives since they use integrated circuits. Even though SSDs use memory chips instead of a mechanical platter that has to be read sequentially, they’re still slower than the computer’s RAM.
