The Generations of Computers - KidsCast!

-




Hello Everyone! Welcome to KidsCast! In today's post, we will be discussing about The Generations of Computers. There are 5 Generations of Computers. These computers used different types of Computer Languages.

The languages used in First and Second Generations of Computers are examples of Low Level Languages. The languages used in the Third, Fourth and Fifth Generations of Computers are examples of High Level Languages.


First Generation:




The period of the First Generation of Computers were from 1946 to 1959. These computers used Vacuum Tubes or Thermionic Valve Machine. The First Generation Computers used a language called Machine Language. The input of this system was based on punched cards and paper tape, the output was displayed on printouts. Examples of these Computers: ENIAC, EDVAC, etc.


Second Generation:





The period of the Second Generation Computers were from 1956 to 1963. The Second Generation Computers used Transistors. In comparison to the First Generation Computer, the size of the Second Generation Computer was smaller. In the Second Generation Computers, Assembly Language was used. UNIVAC 1108, CDC 3600, IBM 7070, and IBM 7094 are examples of second-generation computers.

Third Generation:


The period of The Third Generation Computers were from 1963 to 1971. In comparison to the computers of the second generation, the size of the computers of the third generation was smaller. The third generation computer consumed less power and generated less heat. The maintenance cost of the computers in the third generation was also low. These Computers used Integrated Circuits. PDP-8, PDP-11, ICL 2900, IBM 360 and IBM 370 are examples of Third Generation Computers.

Fourth Generation:
The Period of The Fourth Generation Computers were from 1971 to Present. These Computers used Microprocessors. The Fourth Generation Computers generated less heat. The production cost reduced in comparison to the previous generation. Examples of Fourth Generation Computers: STAR 1000, PDP 11, DEC 10.


Fifth Generation:


The period of Fifth Generation Computers is Ongoing. The computers of the Fifth Generation has high capability and large memory capacity. The computers of the Fifth Generation are based on Artificial Intelligence (AI). The computers of this Generation are fast and multiple tasks can be performed simultaneously. In the Fifth Generation Computers, VLSI (Very Large Scale Integration) technology became ULSI (Ultra Large Scale Integration) technology, resulting in the production of microprocessor chips having Ten Million Electronic Components.

Microorganisms, often too tiny to be seen without a special tool called a microscope, are remarkable living beings that are all around us. These tiny creatures, also known as microbes, have a big impact on our world. While microbes help us in many things, such as decomposition, breaking down things, digestion and making some foods, some other microbes also are dangerous to us. In this article, we will embark on an exciting journey to discover the fascinating world of microorganisms, exploring who they are, their different types, and even some surprising facts that make them both friends and foes. What are Microorganisms? Microorganisms, or microbes for short, are living things that are so small that you can't see them with just your eyes – you need a microscope. They're basically very small and very tiny creatures which you cannot see just by your eyes. They come in different shapes and sizes and are incredibly important, despite being super tiny. Microbes include bacteria, v...

It's a story filled with brave adventurers, important documents, and a quest for freedom. So, grab your time-travelling hats, and let's dive into the fascinating history of the USA! The Early Explorers: Our story begins with the early explorers who came to the land that is now the United States. These adventurous individuals, like C hristopher Columbus, Amerigo Vespucci, and John Cabo t, sailed across the vast oceans to discover new lands. They were looking for a shorter route to Asia but stumbled upon the vast continent of North America instead. So it was by accident that they reached North America. But yes, they had discovered a whole new continent! These discoveries paved the way for future explorations and the eventual founding of the USA. But it didn't come so easily.  Settlers and People: One of the most famous s...
