  1. Computer History By Frankie Ratto

  2. 10 Important Computer Events 1936 Konrad Zuse - Z1 ComputerFirst freely programmable computer. 1942 John Atanasoff & Clifford BerryABC ComputerWho was first in the computing biz is not always as easy as ABC. 1944 Howard Aiken & Grace HopperHarvard Mark I ComputerThe Harvard Mark 1 computer 1946 John Presper Eckert & John W. MauchlyENIAC 1 Computer20,000 vacuum tubes later... 1948 Frederic Williams & Tom KilburnManchester Baby Computer & The Williams TubeBaby and the Williams Tube turn on the memories.

  3. More Events 1947/48John Bardeen, Walter Brattain & Wiliam ShockleyThe TransistorNo, a transistor is not a computer, but this invention greatly affected the history of computers. 1951 John Presper Eckert & John W. MauchlyUNIVAC ComputerFirst commercial computer & able to pick presidential winners. 1953 International Business MachinesIBM 701 EDPM ComputerIBM enters into 'The History of Computers'. 1954 John Backus & IBM FORTRAN Computer Programming LanguageThe first successful high level programming language. 1955(In Use 1959)Stanford Research Institute, Bank of America, and General ElectricERMA and MICRThe first bank industry computer - also MICR (magnetic ink character recognition) for reading checks.

  4. Computer Measurements Bit-1 bit Byte- 8 bits Kilobyte- one thousand bytes Megabyte- one million bytes Gigabyte- one billion bytes Terabyte- one trillion bytes Petabyte- one quadrillion bytes Exabyte- one quintillion bytes Zettabyte-one sextillion bytes RAM- Random Access Memory

  5. Worms, Viruses, and Trojans Oh My! • Who invented the first PC? -Steve Jobs and Steve Wozniak were credited in creating the first PC. • Who invented the first laptop? -Adam Osborne created the first laptop in 1981 • What is a virus, worm, and a trojan? -A computer virus is a computer program that can replicate itself and spread from one computer to another. -Worms are malicious software applications designed to spread via computer networks. Computer worms are one form of malware along with viruses and trojans. A person typically installs worms by inadvertently opening an email attachment or message that contains executable scripts. -Trojan is a malicious program that cannot replicate itself like the computer virus but can cause serious security problems. It appears as a useful program but in reality it has a secret code that can easily access your system.

  6. Major Computer Companies • Microsoft-Bill Gates • Apple-Steve Jobs and Steve Wozniak • Dell-Michael Dell • HP-David Packard • IBM-Thomas J. Watson

  8. Future Computers I think that computers will be able to read your mind in the future. Technology is rapidly changing, so anything can happen in the world of electronics. I also think you will be able to do more with a computer like do all your homework online instead of on sheets of paper.
