DEVELOPMENT OF COMPUTERS

As we are stepping towards the era of 2020, man have consistently been innovative and creative in developing and improving technology for various sectors to make the world a better place for us to live in. If we look closely today, the development of IT and Computer sector and its application have greatly influenced various other sectors like telecommunication, transport, agriculture, labour, finance, etc to be more efficient and effective at their work.

Computers have created a drastic impact in our lives. In fact we are so dependent on computers that life without computers will certainly be incomplete. In current times most of us own computer gadgets like Private Computer Dekstops Notebooks, Tabloids,

It was designed to be used to perform basic arithmetic operations. Every computer supports some form of input, processing as well as output. In a modern computer, these processing is done electronically hence enabling a vastly greater number of calculation to be performed in lesser time. Binary codes which are representations of numerical numbers were used to process images, sounds, text and graphic. In digital computers, there are ones and zeros that represents the electrical on and off states and endless combinations of those to process any input.

Moving on, the development of computer can be assessed from two perspectives. One perspective would be the invention of hardware components over time like vacuum tubes, transistors, integrated circuits and microprocessors that can be referred to as a generation of change. In the other hand, another perspective would be how user friendly were the computers over a period of time. In the 1950s the computers were almost impossible to use except by very patient geniuses. Next in the 1960s and 1970s, it could only be programmable by highly trained people. Lastly, from the 1980s till present time the computers are now smaller cheaper and useable by just about anyone.

From the hardware development perspective, the first generation of computer was the Electronic Numerical Integrator And Computer (ENIAC). These first electronic computers used vacuum tubes. They were huge and complex,
