Among the virtual events the Greater West Bloomfield Historical Society has scheduled this year is a Roosevelt School 100th anniversary open house in October. The school is located in Keego Harbor.

 The Greater West Bloomfield Historical Society and West Bloomfield Parks have teamed up for some virtual programming events this year. One of the events scheduled for November is “D-Day: The Most Important Day in 2,000 Years.”

WEST BLOOMFIELD — In a “step toward normalcy” during the COVID-19 pandemic, the Greater West Bloomfield Historical Society has positioned itself to continue to keep history alive for local residents via virtual programming.

At a July board meeting, GWBHS President Gina Gregory brought up the idea, and according to Cory Taylor,

Computer, device for processing, storing, and displaying information.

Computer once meant a person who did computations, but now the term almost universally refers to automated electronic machinery. The first section of this article focuses on modern digital electronic computers and their design, constituent parts, and applications. The second section covers the history of computing. For details on computer architecture, software, and theory, see computer science.

Computing basics

The first computers were used primarily for numerical calculations. However, as any information can be numerically encoded, people soon realized that computers are capable of general-purpose information processing. Their capacity to handle large amounts of data has extended the range and accuracy of weather forecasting. Their speed has allowed them to make decisions about routing telephone connections through a network and to control mechanical systems such as automobiles, nuclear reactors, and robotic surgical tools. They are also

Just a few years after Pascal, the German Gottfried Wilhelm Leibniz
(co-inventor with Newton of calculus) managed to build a four-function
(addition, subtraction, multiplication, and division) calculator that he called
the stepped reckoner because, instead of gears, it employed fluted
drums having ten flutes arranged around their circumference in a stair-step
fashion. Although the stepped reckoner employed the decimal number system (each
drum had 10 flutes), Leibniz was the first to advocate use of the binary number
system which is fundamental to the operation of modern computers. Leibniz is
considered one of the greatest of the philosophers but he died poor and alone.




Leibniz’s Stepped Reckoner (have you ever heard
“calculating” referred to as “reckoning”?)

Today’s personal computers are drastically different from the massive, hulking machines that emerged out of World War II–and the difference isn’t only in their size. By the 1970s, technology had evolved to the point that individuals–mostly hobbyists and electronics buffs–could purchase unassembled PCs or “microcomputers” and program them for fun, but these early PCs could not perform many of the useful tasks that today’s computers can. Users could do mathematical calculations and play simple games, but most of the machines’ appeal lay in their novelty. Today, hundreds of companies sell personal computers, accessories and sophisticated software and games, and PCs are used for a wide range of functions from basic word processing to editing photos to managing budgets. At home and at work, we use our

A Look at the History of Computers

Before the age of electronics, the closest thing to a computer was the abacus, although, strictly speaking, the abacus is actually a calculator since it requires a human operator. Computers, on the other hand, perform calculations automatically by following a series of built-in commands called software.

In the 20th century, breakthroughs in technology allowed for the ever-evolving computing machines that we now depend upon so totally, we practically never give them a second thought. But even prior to the advent of microprocessors and supercomputers, there were certain notable scientists and inventors who helped lay the groundwork for the technology that’s since drastically reshaped every facet of modern life.

The Language Before the Hardware

The universal language in which computers carry out processor instructions originated in the 17th century in the form of the binary numerical system. Developed by German philosopher and mathematician Gottfried Wilhelm Leibniz, the system came about

History of Computers







This chapter is a brief summary of the history of Computers. It is supplemented by the two PBS documentaries video tapes “Inventing the Future”
And “The Paperback Computer”. The
chapter highlights some of the advances to look for in the documentaries.



In particular, when viewing the movies you should look for two things:

  • The progression in hardware representation of a bit of data:
    1. Vacuum Tubes (1950s) – one bit on the size of a thumb;
    2. Transistors (1950s and 1960s) – one bit on the size of a fingernail;
    3. Integrated Circuits (1960s and 70s) – thousands of bits on the size of a hand
    4. Silicon computer chips (1970s and on) – millions of bits on the size of a finger nail.

  • The progression of the ease of use of computers:
    1. Almost impossible to use except by very patient geniuses (1950s);
    2. Programmable by highly

Computer programming history

Year Event 1843 Ada Lovelace is credited as being the first person to describe or write a computer program. In 1843, she described an algorithm to compute Bernoulli numbers using the Analytical Engine. 1889 The Hollerith tabulating machine was invented by Herman Hollerith in 1889, allowing for data to be programmatically counted and tabulated. 1956 One of the first programming languages, FORTRAN, was introduced to the public on October 15, 1956. It was developed by John Backus and others at IBM. 1958 The second-oldest programming language, LISP was developed by John McCarthy and was first used in 1958. 1959 COBOL started being developed in 1959 by Grace Hopper and Bob Bemer. 1964 The original BASIC programming language was developed by John Kemeny, Mary Keller, and Thomas Kurtz, and was introduced to the public on May 1, 1964. 1965 Simula is considered the first ever object-oriented programming language, developed around 1965

Event-Driven Programming: Introduction, Tutorial, History

In late 2005, I was trying to learn event-driven programming. I searched
the Web for an explanation of the basic concepts of event-driven programming, but I
couldn’t find one. So I wrote one. I hope it will help you in your attempt to learn
event-driven programming.

You can download the paper HERE.

It is available in both PDF format and in Microsoft
Word format. I make it available in Microsoft Word format so that it will be
easy to translate or subset the document, complete with embedded
images.

This document is finalized and no longer being actively maintained, but if you wish
you can leave a review.

Definition of a Computer
Simplest definition of a computer: A device that processes input and generates
output

Key words:

  • Input
  • Output
  • Processes
  • Information

Modern Computers are electronic, complex, and interactive, but can be reduced
to simple input-output processing devices
