The history of computer dated back to the period of scientific revolution (i.e. 1543 - 1678). The calculating machine invented by Blaise Pascal in 1642 and. that of Goffried Liebnits marked the ...
The SSEM (June 1948) was the first such machine to work. The Manchester Mark 1 (Intermediate Version, April 1949) was the first full-sized computer available for use. The completed Manchester Mark 1 (October 1949), with a fast random access magnetic drum, was the first computer with a classic twolevel store.
Assignment 1 - History of Computer - Free download as Word Doc (.doc / .docx), PDF File (.pdf), Text File (.txt) or read online for free. The document traces the evolution of computer technology from ancient counting devices to modern digital computers and networking. It begins with early mechanical calculating aids like the abacus in 1200 AD and Napier's Bones in 1614.

The Atanasoff-Berry Computer (ABC)The Atanasoff-Berry Computer (ABC) The ABC was the first electronic digital computer, invented by John Vincent Atanasoff.
But their history stretches back more than 2500 years to the abacus: a simple calculator made from beads and wires, which is still used in some parts of the world today. The difference between an ancient abacus and a modern computer seems vast, but the principle—making repeated calculations more quickly than the human brain—is exactly the same.
That is one way to approach the history of computing —the history of solid-state electronics in the past 60 years. But computing existed long before the transistor. Ancient astron - omers developed ways to predict the motion of the heavenly bodies. The Greeks deduced the shape and size of Earth. Taxes were summed; distances mapped.
Massively-parallel computer: a parallel computer containing hundreds or thousands of (micro)processors. MIMD: Multiple Instruction streams, Multiple Data streams. Microcomputer: a small computer driven by a microprocessor. Minicomputer: it costs much less than a large computer (such as a mainframe) but can yield very substantial performance.

of communications systems. However, the computer wasn't invented in 1990, and it has a very long history. The very name computer describes the role it originally performed—carrying out tedious arithmetic operations called computations. Indeed, the term computer was once applied not to machines but to people who carried out
to work on the Universal Automatic Computer, or UNIVAC. In 1949, Romington Rand acquired the Eckert-Mauchly Computer corporation and in early 1951 the first UNICAC-1 became operational at the Census Bureau. It was followed by EDVAC (Electronic Discrete Variable Automatic Computer) which had a storage capacity of 1024 words of 44 bits each.

IBM introduced a smaller, more affordable computer in 1954 that proved very popular. The IBM 650 weighed over 900 kg, the attached power supply weighed around 1350 kg and both were held in separate cabinets of roughly 1.5 meters by 0.9 meters by 1.8 meters. It cost $500,000 or could be leased for $3,500 a month.

Generations of Computer: The modern computer took its shape with the arrival of your time. It had been around the 16th century when the evolution of the computer started. The initial computer faced many changes, obviously for the betterment. It continuously improved itself in terms of speed, accuracy, size, and price to urge the form of the fashion
Abstract-In this paper, emphasis has been given on the gradual and continuous advancement of computer from on and before 300BC to 2012 and beyond. During this very long period of time, a simple device like computer has witnessed many significant changes in its manufacturing and development. By and large, the changes are conceptual ...
The word 'computer' has a very interesting origin. It was first used in the 16th century for a person who used to compute, i.e. do calculations. The word was used in the same sense as a noun until the 20th century. Women were hired as human computers to carry out all forms of calculations and computations.

The history of computer begins with the birth of abacus which is believed to be the first computer. It is said that Chinese invented Abacus around 4,000 years ago. It was a wooden rack which has metal rods with beads mounted on them. The beads were moved by the abacus operator according to some rules to perform arithmetic calculations.
