- History of Computer A computing machine is basically an electronic device which is used to input, output, process, and store data but there argon rough definitions which will include devices such as digital calculators and digital watches in the category of a computer. Software is also considered when looking at the history of computers, not only the physical hardware and the capabilities of the hardware purchasable at the particular time. Operating systems with the features they carry and videogames with their utilization of the available applied science are sometimes also used as markers in computer history.The earlier computers were practically larger in comparison to the computers available today, sometimes filling entire rooms or sections of buildings. Some persons may be familiar with the term mainframe which is a large computer which whoremaster do many different tasks simultaneously. Modern mainframes and elder mainframes were not much different in their function whi ch is to provide a centralized bill for all data to be processed and sometimes stored but older mainframes did not have the benefit of the newer technologies available today.As computers evolved and got smaller and smaller, the use of mainframes to get by workloads decreased as standalone computers became more than popular. The difference with standalones versus those attached to the mainframe which were called workstations, is the particular that standalones could mould applications by themselves while workstations depended on the mainframe being online in order to function. Much older mainframes would run different programs based on a schedule and persons were assigned to feed or load the plan application at the appointed time.When the appointed program was scheduled to be run a person would have to load either scoke cards or tape spools into the mainframe in order for it to run the specified application and the workstations would then load the application to the mainframe . In more recent times servers have generally replaced mainframes but in some companies there are still those who use modern mainframes as an preference to having hundreds of servers in different locations. The size of the computer is the greatest measure of how far-off technology has come.We have moved from computers filling entire buildings to laptops that have as much functionality as a desktop and portable enough to push around everyday. A quick timeline of how computers have evolved include the movement from laggard card program input to magnetic tape program input, the travel of storage devices to magnetic drum media, moving from vacuum tube electronic components to transistor electronic components and ultimately the reduction in the size of transistors which is the old reason for computers having reached where they are.An interesting concept to examine in computing would be Moores Law which outlines a trend in computing and the third power, which will be the farthest p oint that computing will reach. As components keep getting smaller and smaller allowing for more features to be crammed into a single circuit, Moores Law dictates that once transistors reach atomic blood corpuscle sizes the improvement of computers will have to stop.
