The Origin of Computing Machines

• Abacus: the ancient Greek and Roman, merely a data storage system• Technology of gears (19C)

– Pascal (France): Adder hard-wired in gears– Leibniz (German): Several selectable operations hard-wired in gears– Charles Babbage (England)

• Difference Engine• Analytical Engine: Read instructions in the form of holes in paper cards

– The first programmer: Ada Byron– cf. Jacquard’s loom

• Electromechanical machines: MARK I, Harvard, 1944• Vacuum tube machines

– 1941, Atanasoff-Berry machine at Iowa State Univ.– Colossus, to decode German messages in England during World War II– 1946, ENIAC (Electro Numerical Integrator And Calculator), Univ. of Penn.

• Semiconductor substrate-based bipolar digital logics– 1958: Jack Kilby’s IC (Nobel prize)– 1962: TTL (Transistor-transistor logic)– 1974: ECL (Emitter-coupled logic)

• CMOS (Complementary Metal Oxide Silicon)-based machines• Biochemical computing machines ?

Jacquard’s Loom (1801) – The first programmed machine

• The steps to performed during the weaving process were determined by patterns of holes in paper cards

Mark-I (1944) – The first electro-mechanical computer

ENIAC (1946)- The first electronic-digital computer

How to Assemble Your PC - Components

• CPU: The processing part of a brain – e.g. Intel Pentium 4 2.0A GHz (Cache 512KB)

• RAM: The memory part of a brain– e.g. Samsung Elec. 256MB DDR SDRAM(PC2100)

• Main board: A scaffold– e.g. Unitec TANK ULTRA DDR (P4X266A)

• HDD: A notebook– e.g. Seagate Barracuda 4 60GB (7200RPM)

• FDD: A letter– e.g. Samsung 3.5 inch Floppy Disk Drive (becoming non-necessary)

• ODD: A long letter or a log– e.g. Samsung Elec. 52x CD-ROM Drive

• Power Supply: A digestive organ for energy supply– e.g. DAO for Pentium 4 250W

• Case: The outer skin– e.g. DAO C710(ATX)

• Monitor, Keyboard, Mouse, Speaker, Camera, LAN Card, Modem, Printer, etc

How expensive your computer is

• You (or your parents) bought a PC: 2,000,000 KRW• Usually, you will use it for three years• Three years = 1,095 days• 2,000,000 KRW / 1,095 days = 1,826 KRW / day• 2,000,000 KRW / (1,095 days * 24 hours) = 76 KRW / hour

• Your PC is consuming ~2,000 KRW each day from your (or your parents’) pocket no matter how frequently you use

How to keep the value of your (or your parents’) money =>

Use it as frequently as possible
