Computer Technology Advancement
From the past to now the computer technology has escalated very rapidly. Unlike the past now a day we have computers that do a lot of processing and that have many features. In our day to day life computers have been a thing that we use very frequently from important business work to scientific work, education and even entertainment.
Throughout the time even computers have been classified under different generations. Mainly there are five generations throughout the timeline. The first generation of computers started from the 1940. The significance of the first generation computers were that the used vacuum tubes. The second generation started from 1956 and they used transistors. With this up gradation the space and the heat emitted became much lesser. The third generation of computers was from 1964 and they consisted of integrated circuits. From 1972 to the present could be taken as the fourth generation of computers. Presently we use microprocessors and the computers that we use now emit less heat and occupy less space, some are even portable. The fifth generation is a very ground breaking generation as it is going to give the computers a thinking capacity as well. From the start of 2010 the fourth generations’ transition to the fifth generations can be seen. In the future we can expect the whole world to be automated.
The types of computers
There are four main types of computers and these types of computers are mainframe computers, mini computers, super computers and microcomputers. First we’ll talk about the computers we buy. We normally buy desktop computer and these computers fall under the category of microcomputers.
These computers are normally produced to general domestic usage and they have rapidly grown in the field of technology. We can buy simply Yoga Notebook Lenovo or even a touchscreen mobile phone now a day.
Supercomputers can be known as the most powerful computers that are available in the world and they are more likely to be used in laboratories and huge research centers. They equip a lot of space yet processes data like no other computer in the world.
The mainframe computers are quite expensive yet low power than super computers and is been mainly used by government agencies and large firms in the world. Even though mainframe computers are the fastest computers even the mainframe computers can process and hold many data and information.
Last but not the least is the mini computers. Mini computers are not normally very powerful as super or mainframe computers but they can certainly process chunks of data with speed efficiently. These computers aren’t single user computers. Normally these kind of computers are used by small business and agencies.
