  1. Computers 101 By: Travis 3rd period

  2. First Computer • Invented by Konrad Zuse in 1936 • Named Z1 computer

  3. “Debug” • In 1878 Thomas Edison coined the term “bug” and “debugging” when working with his inventions

  4. Internet Facts • The Internet began in 1969 by ARPA • It was designed for research, education, and government organizations.

  5. Babbage’s Analytical Engine • A mechanical digital computer which, viewed with the benefit of a century and a half's hindsight, anticipated virtually every aspect of present-day computers.

  6. Tabulating Machine • It was invented for or their ability to count combined facts. These machines reduced a ten-year job to three months

  7. ENIAC • The first general-purpose electronic computer. • Built at The Moore School of Electrical Engineering, now part of the School of Engineering and Applied Science.

  8. Program • An organized list of instructions that, when executed causes the computer to behave in a predetermined manner.

  9. Benefits of using a Transistor over Vacuum Tubes • Smaller size • Lower cost • Lower possible operating voltages • Operation without a warm up period

  10. Microcomputer • Intel’s founder, Robert Noyce, chartered Ted Hoff’s Applications Research Department in 1969, to find new applications for silicon technology.

  11. Binary System • Bit-A binary digit is called a bit. Usually expressed as 0 and 1 the two numbers of the binary numbering system. A bit is the smallest unit of information a computer can use. • Byte-A group of 8 bits are in a byte. With 8 bits there exists 256 possible denary combinations. Large numbers of bytes can be expressed by kilobyte and megabyte.
