The Analytical Machine
The Analytical Engine was, or would have been, the world's first general-purpose computer. Features included a store and mill, analogous to today's memory and processor -
Holes in Cards (Punch Card)
Punch cards were the primary method of storing and retrieving data in the early 1900s, and began being replaced by other methods in the 1960s and today are rarely used. -
Von Neumann Architecture
von Neumann wrote an incomplete set of notes, titled the First Draft of a Report on the EDVAC. This widely distributed paper laid foundations of a computer architecture in which the data and the program are both stored in the computer's memory in the same address space -
ENIAC
t was a secret World War II military project. The challenge was to speed up the tedious mathematical calculations needed to produce artillery firing tables for the Army. -
High-level Programming Language
Designed to be closer to human languages and are easier to use -
UNIVAC
UNIVAC Short for Universal Automatic Computer. The US's first commercially available computer system. Its memory was in the form of mercury delay lines; it involved turning electrical pulses into sound waves, sending them through long tubes of mercury, and re-electrifying them at the other end. -
PC
one of the most significant of the inventions that paved the way for the PC revolution was the microprocessor. Microprocessors were the size of a thumbnail,they could run the computer’s programs, remember information and manage data all by themselves -
UNIX Operating System
Unix is a family of multitasking, multiuser computer operating system. which is an operating system that orchestrates the various parts of a computer from the processor to the keyboard. -
CRAY-1
Cray Research, Inc. is the world’s premier producer of supercomputers high-performance computer systems that can handle a large number of calculations in a very brief time. -
Apple
Woz, one of the founders, had seen the first Altair, which today looks like little more than a box of lights and circuit boards – and was inspired by MITS’ build-it-yourself approach to make something simpler for the rest of us. You can see this philosophy shining through in Apple’s products today. -
Altair
The Altair was the world's first personal computer ( PC ) to attract a substantial number of users. The first Altairs shipped without an operating system, but with an Intel 8080 processor (the first 8-bit chip ) on the CPU card; 256 bytes of memory , and toggle and switch LED panels on the front. -
First Electronis Spreadsheet
Professor Richard Mattessich pioneered the development of computerized speadsheets for use in business accounting.The program helped users input and manipulate a matrix of five columns and 20 rows. -
Windows
Created by Bill Gates and Paul Allen. Started when the two men heard about the Altair 8800, they called MITS (the makers of the Altair), and offered their services to write a version of the new BASIC programming language for the Altair. The Altair BASIC was their first product sold which later gave Gates the idea of starting their own company, which is now known as Microsoft. -
Macintosh
he Macintosh is run by activating pictures (icons) on the screen with a small hand-operated device called a "mouse". the Macintosh is considered to be the first commercially successful computer to use a GUI (Graphical User Interface)
