Overview Invented a numerical wheel was the intelligent Blaise Pascal in 1642 In 1812, Charles Baggage, a member of England’s Royal Astronomers Society, figured out the similarities between mathematics and machines In 1820, Charles Xavier Thomas de Colmar invented the arithometer, a mechanical calculator capable of performing adding, subtracting, multiplying, and division

First-Generation Computer First-Generation computers were introduced in World War II A device called Colossus was a device that could translate German Messages ENIAC was terribly absurd to operate, therefore could perform very complex calculations

Second-Generation Computers 1956 was the year when Second generation computers were actually called, “Second Generation” Transistors were really big, compared to what computers look like today

Third-Generation Computers In 1950, a computer chip was invented The integrated circuit was positively invented by Jack Kilby and Robert Noyce A thin computer chip looks like a thin wafer People have said that the ‘microchip’ is revolutionary

Fourth Generation Computers Personal Computer (PC’s) were first sold in 1947, and in 1981, International Business Machines (IBM) released it’s first PC By 1990, 65, 000 PCs were being used 1 billion computers were used worldwide Computers were evolving very fast and the software was being rushed

Define Hardware and Input/Output Devices It is nearly impossible to work computers without Input/Output Devices. Input is the device that can let us enter information so that work is possible Output is the device that can function the computer to do what it is supposed to do

Processors and Memory The most important is the Central Processing Unit, (CPU) The CPU is basically the brains of any computer Random Access Memory, (RAM) is a storage unit for data It is capable of performing extreme math and can perform millions and even billions of times per second

Hard Drives and Removable Storage Hard Drives, CD-ROMs and floppy disks are all ways to store data, or retrieving data Laptop’s memory hold 60 giga-bytes Currently people, mostly adults are amazed that a big computer, can now fit in a pocket, and can function everything a computer can do

Networks Networking is the most explosive part of having a computer in the industry Every businessmen in America voted to set up networks Nowadays, computers can find networks on it’s own With networks, we can access the internet

Operating Systems Operating systems, (OS), sometimes called platforms, performs two important tasks They manage hardware They Also provide good applications

Software Applications Today, without applications, or Apps for short, people would be infuriated What an app is on a computer, is that it is a software desktop Some software don’t have any types of applications Software very important nowadays
