1. IBM produced the first hard disk drive. Find a page on an official IBM web site describing this disk. When was it made, what was it called, and how much storage space did it offer? (1) Query “IBM” to figure out IBM’s domain name, which is ibm.com (2) Query “site: ibm.com "hard disk"” for pages on IBM’s web site(s) with phrase “hard disk” in them (3) Query “site: ibm.com "hard disk" first” with additional keyword “first” to narrow search Lab 1.4: Smarter Searching on the Web 5 answer (“1956, 305 RAMAC, 5 MB”) found on second hit: http://www.storage.ibm.com/hdd/firsts/n1956.htm 2. Who is often called the “Father of Computing” and when did he live? Charles Babbage and he lived in Teignmouth, Devonshire UK. Found at http://ei.cs.vt.edu/~history/Babbage.html 3. What was the “analytical engine”? It was the design of a mechanical general-purpose computer. Found at: http://en.wikipedia.org/wiki/Analytical_engine 4. Was the Analytical Engine designed to run on electricity? No, it was to be powered by a steam engine and would have been over 30 metres long and 10 meters wide. The input (programs and data) was to be provided to the machine via punched cards, a method being used at the time to direct mechanical looms. For output, the machine would have a printer, a curve plotter and a bell. Found at: http://en.wikipedia.org/wiki/Analytical_engine 5. Who was Ada Lovelace, and how is she related to the “Father of Computing” She was the first known computer programmer. She is mainly known for having written a description of Charles Babbage's early mechanical general-purpose computer, the analytical engine. Found at: http://en.wikipedia.org/wiki/Ada_lovelace 6. Who was Ada Lovelace’s father? Lord Byron- a poet. Found at: http://en.wikipedia.org/wiki/Ada_lovelace 7. What computing “first” is Ada Lovelace known for? The world’s first known computer programmer. Found at: http://inquiry.uiuc.edu/bin/unit_update.cgi?command=select&xmlfile=u10333.xml 8. The ENIAC is often called the first general-purpose computer, though some question this distinction. In kilograms, how much did ENIAC weigh? It weighed140 kilograms. Found at: http://en.wikipedia.org/wiki/ENIAC 9. What was ENIAC designed to be used for? ENIAC was designed and built to calculate artillery firing tables for the U.S. Army's Ballistics Research Laboratory. Found at: http://en.wikipedia.org/wiki/ENIAC 10. In what year was the construction of the ENIAC completed? February 15, 1946 Found at: http://en.wikipedia.org/wiki/ENIAC 11. Some claim that other fully programmable, electronic computers were produced before ENIAC. Find at least one example, the year of its production, and who was responsible for its production. The Z3 was the first, fully programmable, electronic, computer. It was produced by Konrad Zuse in 1941.
