Lets Take A Look Back In Time To See How The Computer Has Evolved



Let’s take a​ look back in​ time to​ see how the​ computer has evolved.
In many ways,​ man has been using computers for millennia: an​ abacus is,​ after all,​ simply a​ very basic form of​ computer .​
The first mechanical calculator (the ‘calculating clock’) was built in​ the​ 17th century .​
Programming with punch-cards has been around for about 200 years now.
It was in​ the​ 1940s,​ however,​ that the​ first electronic,​ digital computers started to​ appear – that is,​ computers as​ we​ know them today .​
These computers were massive machines,​ filling a​ large room (in some cases,​ a​ whole building) and yet having less computing power than a​ simple calculator does today .​
Reprogramming them often required extensive amounts of​ physical rewiring,​ as​ the​ only way the​ computer knew what to​ do was by how it​ was connected together .​
Still,​ these computers were helpful in​ the​ war effort – most famously,​ the​ British code-breaking computers at​ Bletchley Park that broke the​ Germans’ code is​ widely thought to​ have shortened the​ war by years.
Fast forward to​ the​ ‘60s .​
This was when wires and tubes were replaced with the​ transistor – an​ overnight leap forward in​ technology that reduced computers’ size to​ an​ amazing degree,​ replacing the​ hefty vacuum tubes that somewhat like those still used in​ CRT TVs and microwaves .​
Combined with the​ invention of​ semiconductor integration circuits,​ by the​ ‘70s,​ it​ was possible to​ make personal computers small enough for people to​ have in​ their homes.

This is​ generally regarded as​ being the​ beginning of​ the​ ‘computer age’,​ as​ the​ popularity of​ home computers quickly drove prices down and made them very affordable .​
Computer companies sprung up left,​ right and centre,​ hoping to​ carve themselves a​ piece of​ this exploding market .​
The result was chaos and buyer confusion,​ and few of​ them survive today .​
However,​ the​ stage was set for a​ huge computer battle that led to​ the​ machines we​ know and love today.
