Evolution of Computers

Pascaline Calculator

Blaise Pascal in 1642, made a significant change in history by developing a calculator called Arithmetic Machine or Pascaline. It is considered as one of the first mechanical adding machines which perform calculations manually. It could handle numbers up to 999,999,999 and used a series of toothed wheels.

The London Science Museum’s difference engine, the first one actually built from Babbage’s design.

Charles Babbage first designed the Difference Engine by 1822, an automatic mechanical calculator designed to tabulate polynomial functions.

The Analytical Engine

Later he designed the Analytical Engine in 1837 which contained an ALU (arithmetic logic unit), basic flow control, and integrated memory. This was hailed as the first general-purpose computer design.

Charles Babbage, an English mechanical engineer, and polymath originated the concept of a programmable computer. Considered the "father of the computer", he conceptualized and invented the first mechanical computer. It was this design that the basic framework of the computers of today is based on.

Zuse made S2 computing machine, which is considered the first process control computer. Konrad Zuse was successful to achieve the world’s first programmable computer. The first functional program-controlled Turing-complete Z3 became operational in May 1941.

He founded one of the earliest computer businesses in 1941, producing the Z4, which became the world’s first commercial computer.

Types of Computer Hardware

A computer system consists of software and hardware components that work together. The Input devices, Output devices, and the Central Processing Unit which is also called the CPU are basically considered as computer hardware while the software is a set of instructions that can be stored and run by hardware. In this article we will discuss in detail about hardware components and how they function.
