-
The day and month may not be right. Computers began to come about.
-
Was used on all the First Generation computeers.

Was designed to work with binary numbers. Built by Nazi Germany during WWII.
-
Electronic device designed to decode messages encrypted be the German Enigma machine. Contained 1,800 vacuum tubes.
-
Electronic Numerical Intergrator and Computer, was designed to calculate trajectory tables for the U.S. Army. It could perform 5,000 additions per second.
-
Again the date might not be right, but is considered the first commercially successful digital computer. The first UNIVAC computer was constructed under the auspices of the Eckert-Mauchly Computer Corp.
-
Not sure the date again, does not say in the book. They used transistors instead of vacuum tubes.
-
Regulate current or voltage flow and acts as a switch for electronic signals.

IBM, Burroughs, Control Data, Honeywell, and Sperry Rand all manufactured computers with transistors.
-
Operating systems that provided stamdardized routines for input, output, memory management, storage, and other resource managment activities.
-
Used intergrated circutry
-
One of the first two computers to incorperate intergrated circuits.
-
The second of the first two to recieve intergrated circuits.

The first successful minicomputer. They were built to be smaller and less powerful then the mainframe, but still be able to run multiple programs at once.
-
Ted Hoff developed the first general-purpose microprocessor.
-
Motorola released the first 8 bit microprocessor.
-
Was a personal computer developed by Jonathan A. Titus.

Was the first commercial microcomputer. Based on the Intel 8080 processor.
-
A kit containing a system board with 4 KB of RAM.
-
Was an enhanced 8080 microprocessor that was used in many early computer systems.
-
Featured color graphics, expansion slots, a disk drive, a 1.07 MHz 6502 processor, and 16 KB of RAM.
-
Had 4.77 MHz Intell 8088 processor, 16KB of RAM, and single sided 160 KB floppy disks drives.

Featured with RAM upgradable to 640 KB, and a 10 MB hard disk drive.
-
the key feature was the graphical user interface.
-
Featured a graphical user interface that made programs easier to use than those on the commandd-line-base IBM PC.
