History of computers
. What was Steve Jobs and Steve Wozniak contribution to the development of technology?
Steve Jobs and Steve Wozniak contribution the development of technology
Name and describe a device considered to be the first computer.
A device considered to be the first computer is call the abacus, a device on which beads are manipulated to perform calculations.
Where was debugging derived from?
Debugging was derived from when Grace Hopper found a dead moth in the jaws of a mechanical relay, causing the machine to malfunction, she then glued the bug into the operator's logbook.
Prior to the 1980's, where were computers generally used?
High Schools and Colleges before 1980s.
Why was it considered to be digital?
It is digital because the needles were either up or down (on or off, like binary numbers.)
How did it revolutionize the computer industry?
It revolutionized by making computers more efficient allowing more applications to be added.
Bill Gates made a major contribution to technology, what was it?
Micro-Chip
Name the inventors and the inventions of early computer machines?
The early computer machines are the difference engine invented by Charles Babbage in the mid-1800s, in 1890 Herman Hollerith built a punched card machine to process census data used sped things up considerably.
How was the first true digital computer operated?
The first true digital computer operated by dropping needles through holes pinched in cards.
What was the International Business Machines (IBM) Company originally called?
The International Business Machines (IBM) Company was originally called Hollerith Tabulating Company.
Name the main components of each generation of computers in sequential order.
1. Early Computing Machines in the mid-1800s 2. Vacuum Tube Computers in the 1940s 3. Semiconductors in the 1940s 4. Portable Programs 1950ss 5. The Personal Computers in the mid-1970s-1980s
By what means was a government agency assisted by an early computing machine?
A government agency assisted by an early computing machine because in 1890, the US Census was projected to take more than 10 years, but Herman Hollerith built a punched car machine to process census data speed things up considerably.
Name the invention and inventor of the first true digital computer.
The first true digital computer is the Jacquard Loom, invented by Frenchman Joseph Marie Jacquard.
What invention changed the way computers were programmed?
The invention of programming languages and the ability of computers to accept instructions through holes punched in cards allowed computers to work on a variety of scientific, mathematical, and business and problems, this was called applications.
What invention enabled the successor of the mechanical machines?
The invention that enabled the successor of the mechanical machines were the Difference Engine.
What was the main purpose of the ENIAC?
The purpose was to help the military calculate the weapons trajectories for World War 2.
Name and describe the industry that allowed for the creation of the microchip?
The transitory replaced vacuum tubes in radios and televisions and created a new industry - semiconductor which is the industry that created the microchip.
Why were these machines unreliable?
These machines were unreliable because changes in temperature and humidity seriously impaired its efficiency as well as imprecision in the manufacture of its components and the quality of the materials caused problems.
