CSCA Computing Basics. 2. History of Computers. Topics. 1. Definition of computer. 2. Earliest computer. 3. Computer History. 4. Computer Generations. Generation in computer terminology is a change in technology a computer is/was First generation of computer started with using vacuum tubes as the basic. The Generations of Computers. The development of computers started with mechanical and elec- tromechanical devices (17th devices (17 through 19th century).

They operate according to how they are programmed, whether wrongly or truly. Despite its high intelligence, the human brain is lacking rapidity and capacity to dealing with huge tasks of data processing, thus, a machine that can process big amount of data in a very fast way must be developed to solve the demands in terms of data record and communication as well as information. That was the context in which computers emerged. In other words, they have been invented due to the need to find a device that can supersede the human brain in data processing. Therefore, they become instruments conceived to process huge amount of data, very quickly and accurately.

1st to 5th generations of computers

These were inefficient materials which generated a lot of heat, sucked huge electricity and subsequently generated a lot of heat which caused ongoing breakdowns. These computers were limited to solving one problem at a time. Input was based on punched cards and paper tape. Output came out on print-outs.

They were a big improvement over the vacuum tube, despite still subjecting computers to damaging levels of heat. However they were hugely superior to the vacuum tubes, making computers smaller, faster, cheaper and less heavy on electricity use.

This meant programmers could create instructions in words. The early versions of these machines were developed for the atomic energy industry. This led to a massive increase in speed and efficiency of these machines.

These were the first computers where users interacted using keyboards and monitors which interfaced with an operating system, a significant leap up from the punch cards and printouts. This enabled these machines to run several applications at once using a central program which functioned to monitor memory.

What filled a room in the s now fit in the palm of the hand. The Intel chip housed thousands of integrated circuits. Video game systems like Atari generated the interest of general populace in the computers. In , IBM introduced personal computers for home and office use. Ten years later, 65 million PCs were being used.

Five Generations of Computers

It went down from Desktop to laptops to Palmtops. Machintosh introduecd Graphic User Interface in which the users didnt' have to type instructions but could use Mouse for the purpose.

The continued improvement allowed the networking of computers for the sharing of data.

Soon the internet aand World Wide Web appeared on the computer scene and formented the Hi-Tech revolution of 90's. Fifth generations computers are only in the minds of advance research scientiets and being tested out in the laboratories. These computers will be under Artifical Intelligence AI , They will be able to take commands in a audio visual way and carry out instructions. Many of the operations which requires low human intelligence will be perfomed by these computers. Advances in Super Conductor technology will greatly improve the speed of information traffic.

Future looks bright for the computers. The analytical engine was then all but forgotten, with three known exceptions.

Percy Ludgate wrote about the engine in and even designed his own analytical engine it was drawn up in detail but never built. Ludgate's engine would be much smaller than Babbage's of about 8 cubic feet L and hypothetically would be capable of multiplying two decimal-digit numbers in about six seconds. Leonardo Torres y Quevedo and Vannevar Bush also knew of Babbage's work, though the three inventors likely did not know of each other.

They both built electromechanical i. Aiken was inspired by a piece of the Analytical engine deposited at the university by Henry Babbage in , and discovered by him in the s.

He gained access to Babbage's writings and later claimed, pointing to Babbage's books: In molecular nanotechnology, the earliest proposal for a way to implement extremely small and fast computers relied upon logic gates constructed from sliding rods and stubby protrusions to conditionally restrict their motion. Similar computational "rod-logic" was present in the sliding control levers and studded barrel devices which were used to access the microprogram in Babbage's design.

Second Generation Computers The invention of Transistors marked the start of the second generation. Third Generation Computers Although transistors were great deal of improvement over the vacuum tubes, they generated heat and damaged the sensitive areas of the computer.
