Computers: The Wheel of Modern Advancements

Can you imagine a situation where computer functioning has suddenly stopped? There is no prize in guessing the pandemonium that will take shape in every aspect of life in such case. There is any step we can take without computer in modern world. Form emergency services like health, media, banking, security to luxury facilities like tourism, music and entertainment all of them depend on computers.

Origination of Computer

During the 17th century, when the term ‘computer' came into existence, it had hardly any association with machine. Rather it signified a person who used to perform calculations. The term became associated with machine much later, in the late 19th century. However, initially the task of computer was very much complex which consisted of two separate machines to carry out calculation activities. They used to perform automated calculation and programmability. Model K of George Stibitz is regarded as the first prototype of modern computers. During the initial years computers were used only in high important functions like defense activities. Modern smart phones and super computers owe a great part to the early computer models.

Structure of a Computer

The arithmetic logic unit (ALU), the control unit, the memory, and the input and output devices form the main body of a general computer. Electrical circuits are some vital components of a computer's functions. Control unit, memory, Arithmetic/logic unit (ALU), software, hardware and many other equipments and programs run computers.

Computer Usage

I bet you will find it difficult to point out a sector, which has not been touched by computers yet. Drive your car straight to a toll plaza. You will find computer operator is maintaining the automatic system. Traffic signals will become inactive without the backing of computer-aided programs. Defense sector will become toothless without computers. Your office also maintains computer aided registers. Medical equipments will be of no use without the help of computers. Computer aided systems help to solve a complicated criminal case. These modern wonders have heralded a new era in sports arena. These machines are helping to generate revelations about the mysteries of history. The list is endless. Even entertainment world owe a big thanks to this wonder of modern technology.

Computer Controversies

Various sections of societies of different nations voiced against entry of computers in general life. They feared that computers would rob many jobs, as a computer is equal to ten hands. But in reality these scientific machines have given birth to new streams of education as well as job positions. Computer has helped to enhance industrial productivity, thus ensuring better life quality and profit margin. Internet could not have been possible without computers. E-governance is gradually becoming a reality even in under developed countries. But computer related environmental hazards couldn't be ruled out. They consume lots of electricity. Moreover, carbon emission level of these technology giants is a matter of concern. New technologies are coming up to produce e-friendly machines. They will also save lots of power. So, smile all the way with a computer.
